8/18/17: In the garden this week

IMG_20160808_170305

The perennial border displays its brightest colors in August. Rudbeckia subtomentosa, Agastache foeniculum, and Hibiscus mosceutos vie for attention amid the greenery.

August may be a dull time of year, but not in the garden, when the floral display is at its height. This is the time to sit on the patio with a cold drink and enjoy the fruits of your labor. But while you’re out there, here are a few things you could be doing:

water new plantings: I watered my young trees last Sunday and will do so again this week unless we receive considerably more rain tonight and tomorrow: this morning’s downpour amounted to just over half an inch, and I aim for an inch to an inch and a half per week. Remember that perennials and woody plants that you planted this spring or last fall need supplemental water during dry periods throughout this growing season. The rule of thumb is at least an inch of water per week for newly installed plants. In dry weeks throughout the growing season (weeks with less than an inch of rainfall), you need to water all plants installed this spring or last fall. Trees need supplemental watering even longer: the rule of thumb is one year per inch of trunk diameter. How do you know when we’ve received an inch of rain? You can make a highly sophisticated rain gauge–an old plastic container or tin can placed among the plants. I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings each week.

— if you intend to plant a second crop of cool-weather vegetables, you should be starting seed. Water the vegetable garden deeply during dry periods, particularly when the weather is hot, and watch carefully for pests and diseases. Removed diseased plants promptly to prevent spread. Continue to remove the flowers from basil plants as they form. And pick those zucchini before they reach the size of baseball bats!

— continue to properly tie, stake, and prune your tomato plants. Most tomato cages are much too small: the plants outgrow them before they start to bear fruit. And unless tomato plants are properly pruned, by pinching out the suckers, they will be so bushy that they’ll be especially susceptible to fungus infections like verticillium wilt. You’ll find general guidelines for growing tomatoes here and specific watering instructions here.

—  do not plant ornamentals like perennials and shrubs until the weather turns cool in fall. During hot weather, plants put their energy into top growth and blooming rather than growing new roots. If you do continue to plant, water very thoroughly and keep an eye on those new plants. They will need extra water during dry periods, as explained above.

it’s also a bad time to fertilize your lawn or to reseed bare patches, no matter what your lawn-care service tells you. Lawn grasses are adapted to much cooler summers than we experience. All they want to do during this time of year is go dormant, so they can’t use any extra nutrients. Here’s a suggestion: don’t feed at all this year. The lawn will look just fine. Or wait until Labor Day and use one application of a slow-release organic fertilizer. Avoid pesticides, fungicides, and herbicides. Pesticides kill butterfly and firefly larvae and native ground-dwelling bees as well as “bad” insects. And garden chemicals are not so great for kids or pets either; common herbicides, in addition to killing butterfly host plants like violets, are carcinogens. Best to avoid them.

— this is a good time to prune woody plants. You want to prune when the plant is relatively quiescent—when it’s not using so much energy growing, flowering, and fruiting that it has little to spare to heal a wound. This quiescent period occurs between now and leaf drop (abscission) in fall. Basically, when you see that the plant has finished fruiting and that it has formed next year’s buds, but the leaf color is not fading yet, you have a window of time for pruning. Of course, you should prune diseased or injured plants at any time as well as remove any safety hazards, such as overeager shrubs that block sidewalks or diseased trees that might fall down.

do not deadhead your perennials. Seeds represent winter food for birds and other creatures and new plants for you. Collect seeds as they ripen, and store them in a cold place (such as an unheated garage) for next year’s planting, or simply scatter them on the ground where you want them to grow. Do deadhead potentially invasive plants like butterfly bush, miscanthus, and pennisetum grasses however.

Enjoy the garden this week!

Nodding pink onion (Allium cernuum) is not flashy, but it’s nonetheless a star of the August garden. This is a front-of-the-border plant that thrives on full sun and dry soil.

Rudbeckia triloba has just started blooming. I’m always very happy to see it. The flowers are just so cute.

Some clients resist planting native grasses; resistance usually ends when they see the colors of little bluestem (Schizachyrium scoparium). Look carefully at the blues and purples in this plant, and remember that every plant is slightly different.

We are into what I think of as the summer doldrums, or maybe just a reli=atively q uiet period in the garden. Certainly the prairie perennials continue to bloom with all their might, and there are all the asters to look forward to, but in the ornamental garden there’s not much to do except to keep things tidy (that is, if you like your garden to be tidy).

Still, there’s always something to do in the garden, and here are some suggestions:

water new plantings: unless we get a decent amount of rain this weekend (and forecasts do predict rain), go ahead and water newly planted grasses, shrubs, and woody plants. We received just under an inch of rain so far this week. Remember that perennials and woody plants that you planted this spring or last fall need supplemental water during dry periods throughout this growing season. The rule of thumb is at least an inch of water per week for newly installed plants. In dry weeks throughout the growing season (weeks with less than an inch of rainfall), you need to water all plants installed this spring or last fall. How do you know when we’ve received an inch of rain? You can make a highly sophisticated rain gauge–an old plastic container or tin can placed among the plants. I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings each week.

— if you intend to plant a second crop of cool-weather vegetables, you should be buying and starting seed. Water the vegetable garden deeply during dry periods, particularly when the weather is hot, and watch carefully for pests and diseases. Removed diseased plants promptly to prevent spread. Continue to remove the flowers from basil plants as they form; you should already have cut down the plants once to make pesto.

— be sure to properly tie, stake, and prune your tomato plants. Most tomato cages are much too small: the plants outgrow them before they start to bear fruit. And unless tomato plants are properly pruned, by pinching out the suckers, they will be so bushy that they’ll be especially susceptible to fungus infections like verticillium wilt. You’ll find general guidelines for growing tomatoes here and specific watering instructions here.

—  It’s too late to plant. Wait until the weather turns cool in fall. During hot weather, plants put their energy into top growth and blooming rather than growing new roots. If you do continue to plant, water very thoroughly and keep an eye on those new plants. They will need extra water during dry periods, as explained above.

it’s a bad time to fertilize your lawn or to reseed bare patches, no matter what your lawn-care service tells you. Lawn grasses are adapted to much cooler summers than we experience. All they want to do during this time of year is go dormant, so they really can’t use any extra nutrients. Here’s a suggestion: don’t feed at all this year. The lawn will look just fine. Or wait until around Labor Day and use one application of a slow-release organic fertilizer. Avoid pesticides, fungicides, and herbicides. Pesticides kill butterfly and firefly larvae and native ground-dwelling bees as well as “bad” insects. And garden chemicals are not so great for kids or pets either; common herbicides, in addition to killing butterfly host plants like violets, are carcinogens. Best to avoid them.

— it’s time to prune woody plants. You want to prune when the plant is relatively quiescent—when it’s not using a great deal of energy growing, flowering, and fruiting that it has little to spare to healing a wound. This will happen between now and leaf drop in fall. Basically, when you see that the plant has finished fruiting and that it has formed next year’s buds, but the leaf color is not fading yet, you have a window of time for pruning. Of course, you should prune diseased or injured plants at any time as well as remove any safety hazards, such as overeager shrub that block sidewalks or diseased trees that might fall down.

A branch of a large native hazelnut shrub (Corylus americana). It has finished setting fruit as well as forming next spring’s flower buds–the tiny things hanging down from the leaf nodes will become the male flowers. The plant is resting before its last remaining task of the year, leaf abscission, so this is a good time to prune.

do not deadhead your perennials. It will soon be time to collect seeds, which represent winter food for birds and other creatures and new plants for you. Store your seeds in a cold place (such as an unheated garage) for next year’s planting or simply scattered on the ground where you want them to grow. Do deadhead potentially  invasive plants like butterfly bush, however.

Enjoy the garden this week!

Rudbeckia triloba is in bloom now and will put on a display through September and into October. This is a short-lived perennial that readily self-seeds, so new plant appear each year. It remains a manageable 3 feet tall and doesn’t spread aggressively. And the flowers are adorable!

 

 

8/4/17: In the garden this week

IMG_20170804_090331

Two Hibiscus plants blooming side by side. Each flower blooms for one day; you can see buds and spent flowers on both plants. Both are varieties of H. moscheutos, rose mallow, a short-lived native perennial that’s incredibly easy to grow. The birds will enjoy the large black seeds in a month or so.

A hot, humid, mostly dry week, despite frequent predictions of rain: my rain gauge registered just under one inch of rain on Thursday morning after Wednesday’s prolonged showers. I watered my new trees last Sunday and will do so again this week unless we get significant rainfall tomorrow.

But this weather is pretty much ideal for tomatoes, which are the most finicky of plants. They love heat, but if it gets too hot they stop forming new fruits. They need moisture, but if they get too much, the fruit cracks as it ripens. And too little of course causes blossom end rot. The trick is to water consistently and deeply.

The summer hiatus is upon us—it’s too late to plant and to early to clean up. But it’s never too early to plan next year’s garden, so take careful notes on what did well and what didn’t, what could go more smoothly, and how things could be changed in future years. I’m thinking of eliminating more lawn in front and perhaps plant a couple of large trees that would eventually turn a sunny border into a shady on.

Here are a few more immediate chores you could do this week:

water new plantings: unless we get a decent amount of rain this weekend (and forecasts do predict rain), go ahead and water newly planted grasses, shrubs, and woody plants. Remember that perennials and woody plants that you planted this spring or last fall need supplemental water during dry periods throughout this growing season.

Most people keep their lawns growing all summer by applying excessive amounts of water. I never water my lawn. Most summers it turns brown–it goes dormant. This summer, with normal rainfall amounts, it’s still green. So here’s another suggestion: stop watering and see what happens. The lawn will not die, and the earth will be grateful.

The purple glow in this photo is the gazillion tiny flowers of purple lovegrass, Ergostratis spectabilis. This short (12-18″) native grass is impervious to heat and drought, demands poor soil, and displays a cloud of purple flowers and then seeds from August to October. Hard to find, but very easy to grow.

This plant combinations says “the height of summer” in no uncertain terms. The Rudbeckia will be in bloom until September, but the Vernonia (ironweed) will only last a few weeks.

Who says there are only four seasons? To me, we are transitioning from early summer to what I think of as the height of summer: the brightest-colored flowers are blooming, native fruits are ripening fast, fall bloomers such as asters are showing buds, and some late-summer plants, such as great blue lobelia, are coming into bloom. And of course, tomatoes are beginning to ripen fast in the vegetable garden. Here are some not-too-strenuous garden chores for this hot weather (in addition to weeding, made necessary by a season of normal rainfall, in contrast to the past couple of years of drought.

water new plantings: unless we get a decent amount of rain this weekend (and forecasts do predict rain), go ahead and water newly planted grasses, shrubs, and woody plants. Remember that perennials and woody plants that you planted this spring or last fall need supplemental water during dry periods throughout this growing season.

I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings each week.

— all vegetables, including tender crops like tomatoes and peppers and corn, should be planted out by now, and it’s time to remove early greens like lettuce and spinach. In fact, if you intend to plant a second crop of cool-weather vegetables, you should be buying seed. Water deeply during dry periods, particularly when the weather is hot, and watch carefully for pests and diseases. Removed diseased plants promptly to prevent spread. Continue to remove the flowers from basil plants as they form; you should already have cut down the plants to make pesto.

If you do continue to plant, water very thoroughly and keep an eye on those new plants. They will need extra water during dry periods, as explained above.

The first blossoms of Hibiscus moscheutos, rose mallow, opened this week in my garden. This native hibiscus is a short-lived perennial that self seeds readily, produces flowers of different colors, and is very easy to grow.

7/14/17: In the garden this week

IMG_20170711_161319

A luxuriant summer border–a bit too luxuriant this year. With all the rain, I have to keep cutting plants back.

Despite all the rain and warm temperatures throughout this growing season, when I look back at photos of past years’ gardens it’s obvious that many things are blooming 10 days to two weeks later than usual. Normally Rudbeckia subtomentosa begins around July 4; right now the first flowers are  opening, as you see in the picture above.

Over 4 inches of rain this week, and still counting! (It’s raining hard as I write this.) If you have a rain garden, or a spot that might become one, it’s probably been dry for the past 3 years, but it’s most likely nice and wet now. I’m seeing more powdery mildew than in recent seasons, and if it keeps raining, ripening tomatoes may crack on the vine. But all the rain is really good for our poor forest and street trees, which have had a thirsty time recently.

When it stops raining, here are some things you might do in the garden this week:

water new plantings: NOT! Rainfall for the week is well over 4 inches, so nothing should need watering. BUT keep monitoring: perennials and woody plants that you planted this spring or last fall need supplemental water during dry periods. The rule of thumb is at least an inch of water per week for newly installed plants. In dry weeks throughout the growing season (weeks with less than an inch of rainfall), you need to water all plants installed this spring or last fall. How do you know when we’ve received an inch of rain? You can make a highly sophisticated rain gauge–an old plastic container or tin can placed among the plants. I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings each week.

— all vegetables, including tender crops like tomatoes and peppers and corn, should be planted out by now, and it’s time to remove early greens like lettuce and spinach. Water deeply during dry periods, particularly when the weather is hot, and watch carefully for pests and diseases. Removed diseased plants promptly to prevent spread. Remove the flowers from basil plants as they form, and cut down the plants to make pesto as soon as you have enough leaves for a batch.

— be sure to properly tie, stake, and prune your tomato plants. Most tomato cages are much too small: the plants outgrow them before they start to bear fruit. And unless tomato plants are properly pruned, by pinching out the suckers, they will be so bushy that they’ll be especially susceptible to fungus infections like verticillium wilt. You’ll find general guidelines for growing tomatoes here and specific watering instructions here.

—  It’s a bit late to clean up the perennial garden or to divide and replant. Once the weather turns hot, plants put their energy into top growth and blooming. I would no longer move or divide plants, but if you continue to plant, water very thoroughly and keep an eye on those new plants. They will need extra water during dry periods, as explained above.

it’s too late to fertilize your lawn or to reseed bare patches, no matter what your lawn-care service tells you. Here’s a suggestion: don’t feed at all this year. The lawn will look just fine. Or wait until around Labor Day and use one application of a slow-release organic fertilizer. Avoid pesticides, fungicides, and herbicides. Pesticides kill butterfly and firefly larvae and native ground-dwelling bees as well as “bad” insects. And garden chemicals are not so great for kids or pets either; common herbicides, in addition to killing butterfly host plants like violets, are carcinogens. Best to avoid them.

— it’s also a bad time to prune woody plants. The plants are using so much energy growing, flowering, and fruiting that they have little to spare to healing a wound. There will be short window of time later in the summer. Of course, continue to prune diseased or injured plants at any time and to remove any safety hazards, such as overeager shrub that block sidewalks or diseased trees that might fall down.

It’s supposed to stop raining sometime tomorrow! get out and enjoy the garden this week.

Rudbeckias will start to bloom very soon: this is Rudbeckia subtomentosa, the earliest one in my garden. It’s a large, tough plant, and it blooms nonstop from late June through September.

As you approach this long Fourth of July weekend, filled with outdoor activities, take some time to reassess your garden: would you like to spend more time enjoying the outdoors and less time on lawn care? would you like to see more birds and butterflies? Do you see fireflies? (You should, unless you poison them with lawn chemicals and insecticides.) Do your plants attract pollinators? (They should, unless they are sterile hybrids.) How could your outdoor environment be more sustainable and environmentally friendly?

Here are some additional seasonal tasks you might address during this long hoiday weekend:

water new plantings: We received almost no rain in the past week, so perennials and woody plants that you planted this spring or last fall need supplemental water: at least an inch of water, not just a little sprinkle. In addition, if you are still planting despite the hot weather, be sure to water well after planting to settle the new plants in the ground. In dry weeks throughout the growing season (weeks with less than an inch of rainfall), you need to water all plants installed this spring or last fall. How do you know when we’ve received an inch of rain? You can make a highly sophisticated rain gauge–an old plastic container or tin can placed among the plants. I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings each week.

— all vegetables, including tender crops like tomatoes and peppers and corn, should be planted out by now, and it’s time to remove early greens like lettuce and spinach. Water deeply during dry periods, particularly when the weather is hot, and watch carefully for pests and diseases. Removed diseased plants promptly to prevent spread. Remove the flowers from basil plants as they form, and cut down the plants to make pesto as soon as you have enough leaves for a batch. If you don’t grow basil, it’s not too late to buy a flat and plant it out this season.

— be sure to properly tie, stake, and prune your tomato plants. Most tomato cages are much too small: the plants outgrow them before they start to bear fruit. And unless tomato plants are properly pruned, by pinching out the suckers, they will be so bushy that they’ll be especially susceptible to fungus infections like verticillium wilt. You’ll find general guidelines for growing tomatoes here and specific watering instructions here.

—  It’s a bit late to clean up the perennial garden or to divide and replant. Once the weather turns hot, plants put their energy into top growth and blooming.

Monarda didyma, the red species, doesn’t do as well in my garden as the more familiar pink/lavender Monarda fistulosa. This year it’s quite lovely, and both are excellent pollinator plants.

it’s too late to fertilize your lawn or to reseed bare patches, no matter what your lawn-care service tells you. Here’s a suggestion: don’t feed at all this year. The lawn will look just fine. Or wait until around Labor Day and use one application of a slow-release organic fertilizer. Avoid pesticides, fungicides, and herbicides. Pesticides kill butterfly and firefly larvae and native ground-dwelling bees as well as “bad” insects. And garden chemicals are not so great for kids or pets either; common herbicides, in addition to killing butterfly host plants like violets, are carcinogens. Best to avoid them.

— it’s also a bad time to prune woody plants. The plants are using so much energy growing, flowering, and fruiting that they have little to spare to healing a wound. There will be short window of time later in the summer.

Enjoy the garden and the fireflies!

June is bustin’ out (couldn’t resist) in a perennial bed glorious with yellow sundrops (Oenothera fruticosa), orange butterfly weed (Asclepias tuberosa), and bergamot/beebalm (Monarda fistulosa), plus grasses and numerous species that have finished blooming or not yet bloomed. This border gets full sun and was originally planted over 20 years ago. The soil, which is very sandy, has never been amended in any way.

During the past few years of drought, I had forgotten what a gardening season with normal rainfall looks like. I had forgotten how the plants grow so exuberantly that I have to keep cutting them back along paths, in front of patio chairs, near the air conditioner, how quickly tomato plants grow (more on that below). And what it’s like not to have to exhort clients to keep newly-installed plants well watered until they’re established. It’s a pleasant change.

As I write this, the predicted rain has just started. Can I confess that given a choice between a dry weekend and a good soaking rain, I’d vote for the rain in most cases? But the thing about gardening is that we don’t get a choice.

Here are some things you might consider in your garden this week (after the rain stops, of course):

water new plantings: We received about 1 1/2 inches of rain in the past week, so no watering should be necessary this week. However, you should always water well after planting to settle the new plants in the ground. In dry weeks (those with less than an inch of rainfall), you need to water all plants installed this spring or last fall. How do you know when we’ve received an inch of rain? You can make a highly sophisticated rain gauge–an old plastic container or tin can placed among the plants. I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings each week.

— all vegetables, including tender crops like tomatoes and peppers and corn, should be planted out by now, and it will soon be time to remove early greens like lettuce and spinach. Water deeply during dry periods, particularly when the weather is hot, and watch carefully for pests and diseases. Removed diseased plants promptly to prevent spread.

— be sure to properly tie, stake and prune your tomato plants. Most tomato cages are pretty useless: the plants outgrow them before they start to bear fruit. And unless tomato plants are properly pruned, by pinching out the suckers, they will be so bushy that they’ll be especially susceptible to fungus infections like verticillium wilt. You’ll find general guidelines for growing tomatoes here and specific watering instructions here.

—  It’s a bit late to clean up the perennial garden or to divide and replant. Once the weather turns hot, plants put their energy into top growth and blooming. I would no longer move or divide plants, but if you continue to plant, water very thoroughly and keep an eye on those new plants. They will need extra water.

it’s too late to fertilize your lawn or to reseed bare patches, no matter what your lawn-care service tells you. Here’s a suggestion: don’t feed at all this year. The lawn will look just fine. Or wait until around Labor Day and use one application of a slow-release organic fertilizer. Avoid pesticides, fungicides, and herbicides. Pesticides kill butterfly and firefly larvae and native ground-dwelling bees as well as “bad” insects. And garden chemicals are not so great for kids or pets either; common herbicides, in addition to killing butterfly host plants like violets, are carcinogens. Best to avoid them.

— it’s also a bad time to prune woody plants. The plants are using so much energy growing, flowering, and fruiting that they have little to spare to healing a wound. There will be short window of time later in the summer. Of course, continue to prune diseased or injured plants at any time and to remove any safety hazards, such as overeager shrub that block sidewalks.

And don’t forget to count the fireflies! The more you see, the healthier and more sustainable your garden is.

We moved the patio chairs forward to get out of the way of the raspberries. The elderberries (white flowers in background) are especially tall and vigorous this year.
