12/8/17: In the garden this week
Winter is finally settling in–snow tomorrow, and cold temperatures for most of next week. I always hope for a really cold winter, what I think of as a real winter. Cold weather will kill or slow the spread of harmful insects and control the population of out-of control herbivores like deer and rabbits. The garden will look much better next season if we have a cold winter.
Cold or not, there are always garden chores to address:
— start pruning your shrubs. Winter is the time to do this. We used to recommend that you start around the end of December and stop by the beginning of February, to ensure complete dormancy, but as the climate warms, it’s best to snatch at any period of cold weather. Why prune during cold weather? Most important, because the plants will recover best when they don’t have to expend energy on other important tasks. Also because fungi and other disease-causing organisms are less likely to be spread in the cold.
— leave the leaves! Do not rake your leaves out to the curb–you are throwing away the fertility of your soil. Mow over them to use them as lawn fertilizer, use them as mulch on your planting beds (see the photo above), save them to use in compost, but use them in some way on your own property. You can find complete directions here.
— watering new plantings is not necessary this week; we received a scant inch of rain. And of course you can’t water if the temperature is at or near freezing. But be vigilant: Until the ground freezes, in any week in which we receive less than an inch of rain, water thoroughly all woody plants installed this season or last fall. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will not water my new trees and the clients’ gardens I oversee this week.
— clean up the vegetable garden thoroughly: remove all spent plant material. Throw out infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material).
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): mow the grass very short, then spread a 3-4” layer of shredded cedar or hemlock bark mulch over the area to kill the grass. You can also use a thicker layer (12-18″) of leaves. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there now as you collect them.
— collect seeds. Most seeds are ripe, so collect before the birds eat them all. But leave some for the birds that remain through the winter. Seeds of native plants need a cold period before they can germinate, so store them in an unheated garage or shed, or scatter them where you want the plants to grow in spring.
— remove seeds of nonnative (potentially invasive) plants. If you grow butterfly bush (Buddleia), and I hope you don’t, remove the seed heads. The same goes for nonnative ornamental grasses like Miscanthus and Pennisetum. Remove and discard the seedheads–do not compost them. These plants are already invasive in the upper south and mid-Atlantic states and will be here very soon. Better still, remove the plants and replace with natives in the spring. Try this experiment: plant an aster or liatris near your butterfly bush next spring. When the plants are in bloom, watch the butterflies ignore the butterfly bush in favor of the native plants.
— follow a sustainable lawn care regimen: if you feel you must fertilize your lawn, best practice is to give it no more than two applications of slow-release organic fertilizer each season, around Memorial Day and Labor Day. It’s too late to fertilize now, and because the weather has turned cold, it’s too late to seed as well. If you have a place where grass won’t grow, plan to plant something that will, like shade-loving native perennials. If the lawn is doing well, let the grass grow at least 3″ tall for maximum photosynthesis.
— plan for next season: Do it now, while the garden is still green. Notice things that did great and things that didn’t, make lists of areas you want to improve, areas of lawn you could get rid of, places that are getting sunnier or shadier and need new plantings to suit. I bet those dead annuals look pretty terrible now. Plan to replace them with native perennials next year.
The garden catalogs are starting to arrive! Here’s to next year.
11/17/17: In the garden this week
Seasonally cold weather is finally here, and along with it, almost-adequate precipitation (just under an inch this week, and annual totals back up to normal). Most fall color has faded, and the leaves are finally coming down. But there’s still plenty to do in the garden:
— leave the leaves! Do not rake your leaves out to the curb–you are throwing away the fertility of your soil. Mow over them to use them as lawn fertilizer, use them as mulch on your planting beds, save them to use in compost, but use them in some way on your own property. You can find complete directions here.
— watering new plantings is not necessary this week; we received a scant inch of rain over two different rainfalls. But be vigilant: Until the ground freezes, in any week in which we receive less than an inch of rain, water thoroughly all woody plants installed this season or last fall. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will not water my new trees and the clients’ gardens I oversee this week.
— clean up the vegetable garden thoroughly: remove all spent plant material (we finally had a killing frost this week). Throw out infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material).
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): mow the grass very short, then spread a 3-4” layer of shredded cedar or hemlock bark mulch over the area to kill the grass. You can also use a thicker layer (12-18″) of leaves. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there now as you collect them.

— do not clean up the perennial garden until spring: the seeds that remain will feed the birds all winter; the stems and dried leaves will shelter innumerable small creatures; and the detritus the ground harbors next season’s butterflies and moths.
Enjoy the garden this week! And Happy Thanksgiving to all!
11/3/17: In the garden this week
The weather can only be described as freaky. I am longing for autumn–the two cool days this week were a mere teaser. Most trees are holding their leaves, although most perennials have finished blooming. I am still seeing monarchs almost every day. I wonder what they’re finding to eat.
Most garden chores for this week are the same ones I usually suggest in early September, except for this first one:
— leave the leaves! Do not rake your leaves out to the curb–you are throwing away the fertility of your soil. Mow over them to use them as lawn fertilizer, use them as mulch on your planting beds, save them to use in compost, but use them in some way on your own property.
— watering new plantings is not necessary this week because the rainstorm on Tuesday gave us approximately 1 1/2 inches of precipitation. But be vigilant, especially while the weather remains warm: In any week in which we receive less than an inch of rain, water thoroughly all woody plants installed this season or last fall. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will not water my new trees and the clients’ gardens I oversee this week.
— practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers. This is particularly important as the season winds down. When you clean up the garden, throw out infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material). Fall-planted cool-season crops are not doing well this year!
— because of the warm weather, tomato plants have not died back yet, so keep picking, and keep removing suckers and diseased plant material (and again, don’t compost diseased material). Look at this post, this one, and this one for basic information about growing tomatoes. And keep picking: don’t let the fruit rot in the garden.
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): mow the grass very short, then spread a 3-4” layer of shredded cedar or hemlock bark mulch over the area to kill the grass. You can also use a thicker layer (12-18″) of leaves. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there now as you collect them.
— collect seeds. Seed of purple lovegrass and of little bluestem is ripe, as are seeds of joe pye weed, penstemon, prairie onion, and monarda. Aster seeds are ripening. Milkweed seed is done.
— remove seeds of nonnative (potentially invasive) plants. If you grow butterfly bush (Buddleia), and I hope you don’t, remove the seed heads. The same goes for nonnative ornamental grasses like Miscanthus and Pennisetum. Remove and discard the seedheas–do not compost them. These plants are already invasive in the upper south and mid-Atlantic and will be here very soon. Better still, remove the plants and replace with native in the spring.
— follow a sustainable lawn care regimen: if you feel you must fertilize your lawn, best practice is to give it no more than two applications of slow-release organic fertilizer each season, around Memorial Day and Labor Day. However, because of the warm weather, you could fertilize now (and legally you cannot fertilize after November 15). If you reseed bare areas this fall, be sure to water newly seeded areas frequently: grass seed will only germinate if kept moist, so give seeded areas a light sprinkling several times a day. If you have a place where grass won’t grow, plan to plant something that will, like shade-loving native perennials. If the lawn is doing well, let the grass grow at least 3″ tall for maximum photosynthesis. Do not water, or if you feel you absolutely must water, water infrequently and deeply. And always remember: the more you water, the more you’ll have to mow!
— plan for next season: Do it now, while the garden is still green. Notice things that did great and things that didn’t, make lists of areas you want to improve, areas of lawn you could get rid of, places that are getting sunnier or shadier and need new plantings to suit.
— do not clean up the perennial garden until spring: the seeds that remain will feed the birds all winter; the stems and dried leaves will shelter innumerable small creatures; and the detritus the ground harbors next season’s butterflies and moths.
Enjoy the garden this week!
An autumn day at NYBG
This morning I was privileged to attend a master class with landscape architect Caspian Schmidt, a leader in the New Perennial Movement of naturalistic garden design. The class was wonderful–he actually showed us how he does it–but even better was spending the afternoon enjoying the gardens. Here are some highlights.
10/20/17: In the garden this week
Is everyone as sick of warm, dry weather as I am? I feel like I’ve moved to South Carolina. I want a beautiful northern fall.
We’ve had barely an inch of rain since the beginning of September; normal rainfall is over 4 inches per month. And temperatures remain stubbornly high–more than 10 degrees above normal most days. Tomorrow is supposed to be close to 80 degrees once again (a normal high for this time of year is in the low 60s). I look out my window at a backyard of persistent green. NOAA Predictions are for a winter with above-normal temperatures but normal precipitation.
What does this mean for the garden? A lot of chores we normally do in September, such as putting the vegetable garden to bed or feeding the lawn, can be put off until late October or even later (I’m still picking tomatoes). And we may have only a very short window for cold-dependent chores like shrub pruning, which should be done when the plants are completely dormant.
But there are always things you can do in the garden this weekend, if you can bear the heat:
— water new plantings this week: there’s been almost no precipitation for the past 6 weeks. In any week in which we receive less than an inch of rain, water thoroughly all woody plants installed this season or last fall. The soil is very dry, so even perennials planted this spring might be in need of water. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will water my new trees and the clients’ gardens I oversee this week.
— practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers. This is particularly important as the season winds down. Monitor for insect eggs and larvae and remove them before infestations become serious. Throw out infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material). Fall-planted cool-season crops are not doing well this year!
— because of the warm weather, tomatoes continue to ripen their fruit, but be sure to cut back on watering to avoid split fruits: provide no more than an inch of water per week. (If it rains, don’t water.) Keep removing suckers. Look at this post, this one, and this one for basic information about growing tomatoes. And keep picking: don’t let the fruit rot in the garden.
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): mow the grass very short, then spread a 3-4” layer of shredded cedar or hemlock bark mulch over the area to kill the grass. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there now as you collect them.
— collect seeds. Seed of purple lovegrass and of little bluestem is ripe, as are seeds of joe pye weed, penstemon, prairie onion, and monarda. Some aster seeds will be ripe soon. Milkweed seed are almost done. I try to harvest just when the pods split open so I can easily separate the seeds from the down.
— follow a sustainable lawn care regimen: if you feel you must fertilize your lawn, best practice is to give it no more than two applications of slow-release organic fertilizer each season, around Memorial Day and Labor Day. However, because of the warm weather, I would still hold off on fertilizing. If you reseed bare areas this fall, be sure to water newly seeded areas frequently: grass seed will only germinate if kept moist, so give seeded areas a light sprinkling several times a day. If you have a place where grass won’t grow, plan to plant something that will, like shade-loving native perennials. If the lawn is doing well, let the grass grow at least 3″ tall for maximum photosynthesis. Do not water, or if you feel you absolutely must water, water infrequently and deeply. And always remember: the more you water, the more you’ll have to mow!
— plan for next season: Do it now, while the garden is still growing. Notice things that did great and things that didn’t, make lists of areas you want to improve, areas of lawn you could get rid of, places that are getting sunnier or shadier and need new plantings to suit.
— do not clean up the perennial garden until spring: the seeds that remain will feed the birds all winter; the stems and dried leaves will shelter innumerable small creatures; and the detritus the ground harbors next season’s butterflies and moths.
Enjoy the garden this week and always. It’s not too cold for a cookout!
10/6/17: In the garden this week
I don’t know about you, but I could have done without the return of summer temperatures. A little more precipitation would be nice as well (last night rainfall was less than a quarter inch). In other words, wouldn’t it be nice to have fall, with crisp days, chilly nights, and lots of colorful leaves?
Although warm, dry weather is not good for fall planting, there are still lots of things you can do in the garden:
— water new plantings this week: there’s been almost no precipitation for the past 4 weeks. In any week in which we receive less than an inch of rain, water all woody plants installed this season or last fall. The soil is very dry, so even perennials planted this spring might be in need of a little extra water. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will water my new trees and the clients’ gardens I oversee this week; last Sunday I’ll even watered some of the perennials I put in this past spring.
— practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers. This is particularly important as the season winds down. Monitor for insect eggs and larvae and remove them before infestations become serious. Throw out infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material).
— because of the warm weather, tomatoes continue to ripen their fruit, but be sure to cut back on watering to avoid split fruits: provide no more than an inch of water per week. (If it rains, don’t water.) Keep removing suckers. Look at this post, this one, and this one for basic information about growing tomatoes. And keep picking: don’t let the fruit rot in the garden.
— continue to plant cool-weather crops such as lettuce, arugula, spinach, mustard greens, and peas for fall harvest. I’m betting on a warm fall, which means an extended season.
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): mow the grass very short, then spread a 3-4” layer of shredded cedar or hemlock bark mulch over the area to kill the grass. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there now as you collect them.
— collect seeds. Seed of purple lovegrass and of little bluestem is ripe, as are seeds of joe pye weed, penstemon, prairie onion, and monarda. Some aster seeds will be ripe soon.

— do not clean up the perennial garden until spring: the seeds that remain will feed the birds all winter; the stems and dried leaves will shelter innumerable small creatures; and the detritus the ground harbors next season’s butterflies and moths.
Enjoy the garden this week, and think good thoughts about rain, followed by crisp, colorful autumn leaves.
9/29/17: In the garden this week
After several weeks of unseasonable heat and drought, we finally feel a hint of fall today (thought still no rain in sight). Fruits have ripened, but most trees and shrubs are holding fast to their leaves, which for the most part look both green and sad. Some early-turning shrubs and trees are showing color, but the color is subdued. The drought and heat are having an effect.
In the vegetable garden the prolonged heat means that pests and diseases have longer than usual to weak havoc, and fall cool-weather crops are sparse. On the positive side, tomato plants are still producing.
Fall is a good time to plant, especially trees and shrubs (though not as good as spring). But the reason it’s good is the cool temperatures: plants concentrate on growing roots when the soil turns cool, top growth when it’s warm. So far this fall has NOT been a good time to plant, although lots of watering helps.
Fall is a good time for lots of other garden chores, however:
— water new plantings this week: there’s been almost no precipitation for the past 3 weeks. In any week in which we receive less than an inch of rain, water all woody plants installed this season or last fall. The soil is very dry, so even perennials planted this spring might be in need of a little extra water. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will water my new trees and the clients’ gardens I oversee this week, and on Sunday I’ll water some of the perennials I put in this past spring.
— practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers. This is particularly important as the season winds down. Monitor for insect eggs and larvae and remove them before infestations become serious. Throw out infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material).
— as tomatoes ripen their fruit, cut back on watering to avoid split fruits: provide no more than an inch of water per week. (If it rains, don’t water.) Keep removing suckers. Look at this post, this one, and this one for basic information about growing tomatoes. And keep picking: don’t let the fruit rot in the garden.
— continue to plant cool-weather crops such as lettuce, arugula, spinach, mustard greens, and peas for fall harvest. I’m betting on a war fall.
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): mow the grass very short, then spread a 3-4” layer of cedar or hemlock bark mulch over the area to kill the grass. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there now as you collect them.
— collect seeds. Seed of purple lovegrass and of little bluestem is ripe, as are seeds of nodding joe pye weed, penstemon, prairie onion, and monarda. Milkweed seed needs to be collected almost daily. I try to harvest just when the pods split open so I can easily separate the seeds from the down.
— follow a sustainable lawn care regimen: if you feel you must fertilize your lawn, best practice is to give it no more than two applications of slow-release organic fertilizer each season, around Memorial Day and Labor Day. Now that the nights are cool, it’s a good time to reseed bare areas. But be sure to water newly seeded areas frequently: grass seed will only germinate if kept moist, so give seeded areas a light sprinkling several times a day. If you have a place where grass won’t grow, plan to plant something that will, like shade-loving native perennials. Let the grass grow at least 3″ tall for maximum photosynthesis. Lawns certainly do not need water. And always remember: the more you water, the more you’ll have to mow!
— plan for next season: Do it now, while the garden is still growing. Notice things that did great and things that didn’t, make lists of areas you want to improve, areas of lawn you could get rid of, places that are getting sunnier or shadier and need new plantings to suit.
Enjoy the garden this week! Keep a lookout for fall monarch migration (they’re going south). Will they find nectar for the journey in your garden? If not, plant some asters!
9/8/17: In the garden this week
It feels like fall is coming early. The evenings and mornings are crisp, and many trees are already showing color. I hope it’s a sign of a cold (dare I say normal?) winter. However, the National Weather Service is predicting above-normal temperatures for the Northeast over the next three months. We must adjust to the new normal: zone 7 rather than zone 6; more fungus diseases of plants; more insect pests.
At least rainfall has been normal this year, even slightly above average (approximately 52 inches for the past year versus a normal of 49). The garden doesn’t look nearly as tired as it usually does in September; I’ve had to water my newly installed trees only two or three times. Normal rainfall is good for the street trees, too: they really suffered during the drought of the previous two growing seasons.
The weather over the next few days promises to be perfect for gardening, so here are some things you might address:
— no need to water new plantings this week: we received approximately 2 inches of rain the past week. But in general, in any week in which we receive less than an inch of rain, water all woody plants installed this season or last fall. Perennials planted this spring should be well-established by now. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I will not water my new trees or the clients’ gardens I oversee this week.
— practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers. This is particularly important as the season winds down. Monitor for insect eggs and larvae and remove them before infestations become serious. Throw out badly infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material).
— as tomatoes ripen their fruit, cut back on watering to avoid split fruits: provide no more than an inch of water per week. (If it rains, don’t water.) Keep removing suckers. Look at this post, this one, and this one for basic information about growing tomatoes. And keep picking: don’t let the fruit rot in the garden.
— plant cool-weather crops such as lettuce, arugula, spinach, mustard greens, and peas for fall harvest.
— extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): spread a 3-4” layer of cedar or hemlock bark mulch over the area to kill the grass. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there as you collect them.
— collect seeds. Coreopsis seed ripens nearly every day. So does seed of daisy fleabane, a lovely native annual. It pops up in different parts of my garden each year. Seed of purple lovegrass and of little bluestem is ripening, as are seeds of nodding joe pye weed, penstemon, prairie onion, and monarda. Milkweed seed needs to be collected almost daily. I try to harvest just when the pods split open so I can easily separate the seeds from the down.
— follow a sustainable lawn care regimen: if you feel you must fertilize your lawn, best practice is to give it no more than two applications of slow-release organic fertilizer each season, around Memorial Day and Labor Day. Now that the nights are cool, it’s a good time to reseed bare areas.

Lawns certainly do not need water. And always remember: the more you water, the more you’ll have to mow!
— plan for next season: Do it now, while the garden is still growing. Notice things that did great and things that didn’t, make lists of areas you want to improve, areas of lawn you could get rid of, places that are getting sunnier or shadier and need new plantings to suit.
Enjoy the garden this week!
The garden right now
I hope you enjoy these pictures of the early fall garden, taken yesterday, on this rainy day.
