7/31/15: In the garden this week

_DSC7103

Little bluestem, one of the toughest native grasses and, to my eyes, one of the most beautiful, is putting out its seed stalks now and will soon flower.

We’re having a heat wave; this weather shows the benefit of planting natives. Tough prairie plants stand up to heat and drought and just go on blooming. The sunny border is at its most colorful and exuberant right now.

Yesterday’s rain was abundant in some places, but according to my plastic rain gauge, we got less than half an inch, so the vegetable garden and newly planted shrubs and perennials need supplemental watering this week. Other than that, there is little to do in the garden:

water new plantings: newly installed plants and annuals, like vegetables, need watering. Any week in which we receive less than an inch of rain, water all woody plants installed this spring or last season. Perennials planted last spring should be well-established, but those planted last fall and this spring need supplemental watering during dry spells. How do you know when we’ve received an inch of rain? An old yogurt container placed on the ground among the plants makes a great rain gauge. A tunafish or catfood can works equally well.

practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers: 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). Cucumber vines are showing signs of wilt: remove them immediately to prevent the spread of this fungal disease. Pick frequently: smaller vegetables taste better.

— As tomatoes ripen their fruit, cut back on watering to avoid split fruits. Keep removing suckers all summer long. Look at this post, this one, and this one for basic information about growing tomatoes.

Plan the fall vegetable garden: second crops of cool-season plants like peas, lettuce, and spinach can seeded directly in the garden in August.

— it’s not too late to extend a garden bed or start a new one, and it’s always a great idea to eliminate some lawn: spread a 3-4 inch layer of cedar or hemlock bark mulch over the area to kill the grass. In the fall, you’ll be able to plant right through the dying grass and mulch. I mulched an area of lawn about a month ago and am scattering perennials seeds there as they ripen.

— it will soon be a good time to prune woody plants. Once all growth, flowering, and fruiting are done, the plants are relatively, but not completely, dormant, giving you a window of time to prune before they get ready for their next critical task: leaf abscission (shutting down for the winter). I do most of my pruning in winter, but I also prune back shrubs as needed after they have ripened their fruit.

— 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 now to reseed bare areas: wait until early fall. (Better still, if you have a place where grass won’t grow, plant something that will, like shade-loving native perennials.) Let the grass grow at least 3″ tall for maximum photosynthesis. Lawns do not need water now (or ever), but if you do water, do it infrequently and deeply to encourage deep root growth. One inch of water once a week is much better than a few minutes each day (watering every day is likely to cause fungal diseases). But remember: the more you water, the more you’ll have to mow! If you hold off on watering entirely, your lawn will go dormant until the next rain, but it will not die.

Stay cool! I wish everyone a shady patio and a glass of lemonade this weekend.

Sometimes Rudbeckias are almost too exuberant. You can find them in any size to suit your garden. This is R. subtomentosa, which grows up to 5′ tall. I give away plants every spring.

Sheep

https://upload.wikimedia.org/wikipedia/commons/7/72/Detail_Thaddeus_Wilkerson_Postcard_Sheep_Fold_Central_Park_NY.jpg

Central Park, circa 1910. Detail of the Thaddeus Wilkerson photo postcard #53, ‘Sheep Fold, Central Park, New York’

Yes, sheep grazed the Sheep Meadow in Central Park until 1934, when Robert Moses (who else?) had them moved to Prospect Park and then to the Catskills. Sheep Meadow was part of the original plan for Central Park; although it was first used as a parade ground for military drills, it soon became a peaceful bucolic space. And I bet that lawn was healthy, green, and sustainable while the sheep were there to maintain it.

What is it about sheep? I’ve just finished reading The Shepherd’s Life: Modern Dispatches from an Ancient Landscape, by James Rebanks. The author grew up in the English Lake District in a family of shepherds and wanted nothing more than to follow in his grandfather’s and father’s footsteps: raising good sheep, maintaining the family farm, and carrying on an ancient tradition. But he also, rather improbably, went to Oxford, and he advises UNESCO on sustainable tourism, traveling all over the world to examine traditional ways of life.

The book is an autobiography, but it’s also a detailed description of a place (one of the most gorgeous places on Earth) and a way of life that used to be common but that has nearly disappeared. Rebanks and his fellow shepherds practice traditional pastoral techniques: moving sheep throughout the seasons to use the land sustainable, raising breeds of sheep that are best adapted to a harsh environment, caring deeply for the animals and the land. He says that the yearly rhythms of the Lake District haven’t changed appreciably in 1000 years (and that the millions of tourists who visit the Lakes each year are completely oblivious to the traditional way of life that’s going on all around them). His appreciation for the flowery, fragrant, vitally important hay he makes to keep the sheep going all winter, and his despair when a wet harvest season destroys it, are equally memorable.

I learned that sheep are much smarter than I thought: older ewes know how to shelter from a snowstorm, for example, and will prevent younger, inexperienced ewes from choosing a more dangerous spot. I also learned that sheep dogs are just as smart as I thought, if not smarter, and that their work is absolutely essential, but that you can spoil a good dog with poor training. I learned that pastoralism is muddy, bloody, and often, to a city dweller, just plain gross, and that city folks who try it often can’t make it through the first (8-month-long) winter. The descriptions of the work involved in protecting the sheep during a snowstorm, or caring for them during lambing time, are unforgettable.

In case you’d like to see sheep on a daily basis, take a look at Google Sheep View, a site that uploads images including sheep from Google Street View every day. You’ll see some beautiful parts of the world. Here’s a “haunted ghost sheep” in Donegal, Ireland.

7/24/15: In the garden this week

DSCN1662

The border has finally turned yellow! Two species of Rudbeckia create the fire, along with two species of perennial sunflower and some late-blooming butterflyweed. The tall purple flowers floating in the breeze are ironweed, Vernonia fasciulata.

Compare this photo with the ones from last week and week before to see how the border evolves over time. The shade garden changes almost daily as well; here’s a picture of that gorgeous shade-loving joe pye weed taken a couple of days ago:

_DSC1663

Sweet joe pye weed (Eupatorium purpureum) grows to great height with less than half a day of syn.

This is the time of year when there’s little to do in the ornamental garden (except admire it), although the vegetable garden needs continual tending. After last week’s oppressive heat, the weather has been pleasant, but much too dry. We are in a drought: precipitation levels have been below normal for the past 90 days. So pay particular attention to the water needs of your vegetable garden and newly installed woody plants and perennials.

water new plantings: newly installed plants and annuals, like vegetables, need watering. Any week in which we receive less than an inch of rain, water all woody plants installed this spring or last season. Perennials planted last spring should be well-established, but those planted last fall and this spring need supplemental watering during dry spells. 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.

Columbine is almost finished ripening seed, and coreopsis seed ripens nearly every day.

Once all growth, flowering, and fruiting are done, the plants are relatively resting, giving you a window of time to prune before they get ready for their next critical task: leaf abscission (shutting down for the winter). I do most of my pruning in winter, but I also prune back shrubs as needed after they have ripened their fruit.

It’s a lazy time for humans in the garden but a busy time for birds, as several native shrubs ripen their fruits. Elderberry, grey dogwood, and black chokeberry fruits (shown here) are gradually ripening, and the birds check them out every day. Hazelnuts ripened this week, and all that’s left are piles of hulls on the ground.

My latest Backyard Environmentalist column appeared on the North Jersey newspapers website and in the Glen Rock Gazette today. Please take a few minutes to check it out.

Stay cool, and enjoy the garden this week!

The Lamiaceae

Beebalm (Monarda fistulosa) began to bloom this week.

Beebalm (Monarda fistulosa) is an easy-to-grow native plant that belongs to the Lamiaceae, or mint family. The square stems, strongly opposite leaves, and lipped flowers are family characteristics.

The Lamiaceae (the “-aceae” ending, pronounced “A-C-A,” always denotes a family) is a large and widespread plant family that includes over 230 genera and 7,000 species, mostly forbs (non-woody flowering plants) or small woody plants. It is commonly referred to as the mint family, and it includes most of our common culinary herbs, including the mints, basil, thyme, marjoram and oregano, rosemary, sage, and lavender. It also includes many familiar garden plants: in addition to beebalm (bergamot, Monarda), these include Agastache, Ajuga, Callicarpa, Caryopteris, Coleus, Glechoma (a weed), Lamium, Nepeta (catmints), Physostegia virginiana (obedient plant, a native perennial), Salvia (ornamental sages), and Stachys.

The aromas and flavors that make many members of this family pleasing to us as culinary herbs make them displeasing to animals. Most furry pests, like deer and rabbits and woodchucks, avoid all members of this family, which is why you can plant most culinary herbs (with the exception of parsley and dill, both members of the Apiaceae) in an unfenced garden. Although some insects do attack mints, most critters leave them alone.

Which leads us to their greatest benefit in the garden: they are distasteful to most four-footed garden pests, so if you scatter them throughout the garden, they protect or hide the more appealing plants. For example, Asters, Coreopsis, Phlox, and Echinacea are extremely attractive to deer and rabbits.But it you place these plants among members of the mint family, and they are much less likely to be eaten.

There are numerous native family members. Best known are several species of Monarda: M. fistulosa, shown above, blooms in shades of pink and lavender; M. didyma has bright red flowers. Both are about 3-4′ tall, perennial, and very easy to grow as long as they get at least half a day of sun. M. punctata, dotted mint, is an annual, although it self-seeds easily. It’s about 2′ tall, also a sun-lover, and is in bloom right now.

_DSC1655

Dotted mint (Monarda punctata) is in bloom now. Notice the beautiful flame-shaped milkweed pods behind it. There’s some late-blooming M. didyma to the right.

_DSC1652

M. punctata’s flowers are the small, lipped, dotted structures. The large curved white “petals” are bracts, or modified leaves.

Also in bloom now is Agastache foeniculum, or lavender hyssop, a biennial (but easy to keep going with seed). This plant has an anise, or licorice scent, and the edible flowers make a refreshing addition to salads (in small amounts only–the taste is very strong). It’s about 3′ tall and like its cousins needs a sunny spot.

_DSC1645

Stalking out

_DSC1598

Little bluestem (Schizachrium scoparium) in late July, when the flowering stalks reach above the leaves.

Little bluestem is the dominant grass of much of North America; it’s also one of the best native grasses for the average home garden. It’s a nice compact size, never reaching much above 3 feet tall, and for most of the growing season it forms a neat and beautiful mound shape. Individual plants show a great deal of color variation, ranging from deep green to subtle blue-grey. This time of year, it begins to stalk out, or send up flowering stems. The inconspicuous flowers are gentle shades of tan, green, purple, and blue, and the seedheads are golden. In fall, the plant turns first russet and then tan, and it glows in the sun. And the birds eat the seeds as fast as they ripen.

Little bluestem just stalking out.

Individual plants of little bluestem show a great deal of color variation. The plant on the right shows how the species got its common name.

The current hot, dry weather doesn’t bother this plant–in fact, it prefers it. It thrives in dry sites. If your soil is very rich or tends to be moist, choose a different prairie grass, such as prairie dropseed (Sporobulus heterolepsis). Prairie dropseed is finer-textured than little bluestem, but it is about the same height and forms a similarly attractive mound shape.When I plant prairie dropseed in my sandy soil, I mix in a scoop of compost.

Farmer’s markets and CSAs (and an easy recipe)

Today was a pick-your own day at the CSA we belong to, and we fully intended to have a nice trip up to Warwick, NY, pick peas, sugar snaps, and herbs, and buy strawberries and tomatoes at a farmstand, and get fabulous ice cream at a local dairy. But by 10:00 the temperature was over 90 degrees, so we decided to visit a farmer’s market instead. We went to the Ramsay market, a large one that operates on Sundays from 9:00 to 2:00 at the train station. They were out of strawberries, but we got gorgeous and delicious peaches, apricots, and plums, in addition to vegetables.

If you don’t belong to a CSA or shop at farmer’s markets, I encourage you to do so. The Jersey Fresh website lists both by county. (If you live in northern New Jersey, check out the many small farms that operate in the famous black dirt region around Warwick, NY, at well). You’ll get fresh, healthful, and delicious produce while you help support open space and local agriculture.

There’s no substitute for fresh tomatoes and basil. With tomatoes from the farmer’s market and basil from the CSA, I made a caprese salad that will form an uncooked sauce for tonight’s pasta. Here’s what you do: cut up 1 lb. of Roma tomatoes and about 12 oz. of fresh mozzarella cheese in 1/2-inch dice. Tear about 16 large basil leaves in small pieces. Mix everything in a large bowl (large enough to hold the cooked pasta, too), and season liberally with salt, pepper, and olive oil. You need quite a bit of olive oil.

Cover and leave the sauce to sit at room temperature for several hours (the flavors will blend, and the tomatoes will release their juices). At dinner time, cook 1 lb. of pasta (tubular or shell shapes work best), drain, and mix the hot pasta with the sauce. Serve immediately.

Serves 4-6 people. Leftovers can be refrigerated and then very briefly reheated in a microwave to bring them back to room temperature.

7/17/15: In the garden this week

Everything’s finally turning yellow: Rudbeckia subtomentosa will dominate the sunny border from now through September. Compare this picture with the one taken on July 3.

It’s a funny summer season: some plants, like Rudbeckia, are blooming a bit late; others, like Boltonia, are early. Shade asters are showing buds–surely it’s almost a month too early for that to happen–but sun-loving asters are not.

In the shade garden, Eupatorium purpureum has reached the height of bloom, and the butterflies love it, as they do all plants in this large genus.

DSCN1639

Besides relaxing in the shade, here are some tasks you might accomplish in the garden this week:

water new plantings: for the first time in quite a while, we had a dry week, so newly installed plants need watering. Any week in which we receive less than an inch of rain, water all woody plants installed this spring or last season. Perennials planted last spring should be well-established, but those planted last fall and this spring need supplemental watering during dry spells. 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.

Toward the back left of the photo, you’ll see Eupatorium dubium ‘Little Joe,’ a handsome cultivar I put in late last summer. So far, I’m pleased with it, but I’m not sure yet that it attracts pollinators as well as the species. This grouping also includes culver’s root (Veronicastrum virginicum; white), a perennial sunflower (but I can’t remember which one), lavender hyssop (Agastache foenicuoum; light purple), and Rudbeckia (R. triloba and subtomentosa).

The garden right now

On this dreary, cloudy day, let’s look at some bright and cheerful flowers. Here are some pictures of the garden taken yesterday.

_DSC1516

Wild petunia (Ruellia humilis) grows about 12-18 inches tall and likes full sun and dry soil. I love it, but so do the rabbits, so I hide it among the sundrops, which are about the same height but bloom earlier in the season.

_DSC1537

Bergamot (Monarda fistulosa) has been in bloom since late May, and most plants are almost finished, but . . .

_DSC1543

. . . some individual plants are still in full bloom. This plant both self-seeds freely and spreads by rhizomes, and it appears in a natural range of shades from pale lavender to bright pink.

_DSC1548

Rudbeckia (this one is R. subtomentosa) started blooming a bit late this year, but it will be in bloom through September. The purple is a cultivar of Phlox paniculata.

_DSC1565

Hoary vervain (Verbena stricta) is relatively new to my garden, but it will probably be promoted to “Indomitable” status.

_DSC1566

Ironweed (Vernonia fasciculata) has gorgeous rosy-purple flowers that butterflies adore, but the bloom is relatively short-lived (and the plants are 8 feet tall).

7/10/15: In the garden this week

_DSC1508

This is the same part of the garden I showed you last week. Orange butterflyweed is almost finished blooming, and culver’s root (white) dominates for a short time while we wait for Rudbeckia to take command.

The garden changes so quickly in midsummer that I thought you would enjoy seeing the same views for a couple of weeks in a row. Compare this photos with last week’s—there’s not quite as much yellow as I expected, but the Rudbeckia is certainly primed to take over. In the shadier garden, the sweet joe pye weed that was in bud last week is in full bloom.

_DSC1451

This garden gets only half a day of sun. The sweet joe pye weed (Eupatorium purpureum) is at its peak as the orange butterflyweed fades.

Here are some chores you might attend to in the garden this week:

water new plantings: we got well over an inch of rain this past week, so no watering is needed now, but keep watching. Any week in which we receive less than an inch of rain, water all woody plants installed this spring or last season. Perennials planted last spring should be well-established, but those planted last fall and this spring need supplemental watering during dry spells. 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.

finish harvesting early greens such as lettuce, spinach, arugula, mustard greens, and mesclun mix, plus peas and radishes. As greens bolt, or go to seed, pull the plants and plant something else. A row of beans, perhaps?

practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers: Monitor for insect eggs and larvae and remove them before infestations become serious.

Culver’s root (Veronicastrum virginicum) does well in any sunny site. It attracts pollinators by the score and makes a nice backdrop for more colorful plants. Beebalm (Monarda fistulosa) has been in bloom since late May and won’t stop anytime soon.

7/3/15: In the garden this week

_DSC1351

Part of a sunny border. As Monarda and milkweeds begin to fade, Rudbeckias, sunflowers, and Boltonia will take over.

The first Rudbeckias are beginning to bloom: it’s summer! In my garden, Rudbeckia subtomentosa begins the show, usually around July 4, and continues blooming until September. Only a few are just opening, so they’re hard to see in the photo. Next week the predominant color in this same view will be yellow.

The shade garden presents quite a different show:

_DSC1431

This garden gets morning sun and is in deep shade by mid- afternoon. Sweet joe pye weed (Eupatorium purpureum) grows 8′ tall with only half a day of sun. Goldenrod will soon take over.

Wildlife has been abundant this week: we’ve seen many butterfies, including Peck’s and silver-spotted skippers, red admirals, monarchs, and small brown ones that fly so fast we can’t get a good look at them; hummingbirds, flickers and red-headed woodpeckers (a pair of each), besides the usual suspects: mockingbirds, catbirds, robins. If you’d like to go a bit farther afield to search for wildlife, today’s NY Times has a great article on city critters. And by the way, it’s an open secret that NYC is absolutely delightful in summer. New Yorkers head for the beach; museums, theaters, and restaurants are uncrowded. Check out the High Line at dusk. It’s magical.

This long weekend is perfect for hanging out in the garden while the burgers cook on the grill. In between beers, you might want to think about these fairly simple tasks:

water new plantings: we got about an inch of rain this past week, so no watering is needed now, but keep watching. Any week in which we receive less than an inch of rain, water all woody plants installed this spring or last season.

While we’re relaxing in the garden, predatory insects are taking care of it for us. If I look carefully at my Rudbeckia plants, each tall spike is capped by a daddy long legs. I don’t see any pests, but there must be some. Thanks, guys!

Happy Fourth!
