4/1/16: In the garden this week

_DSC4437

We lost a large Norway maple in the windstorm on Monday night. It smashed one of our cars; luckily, we were out, or it would have smashed both. The only good thing about this tree is that its rotten branches sheltered a lot of birds. Scroll down to the bottom of the post to see what’s left.

It’s been an eventful week, to say the least, in and out of the garden. Truly bizarre weather, very strong winds; it’s 70 degrees now, but it’s supposed to snow on Monday.

Are you absolutely itching to get out there and plant? It really is too early, but I did succumb to temptation yesterday afternoon and dig up and divide a couple of plants of very tough native grasses. Grasses respond best to being divided in early spring, and I knew we were going to have some rain, so I went for it. But I’ll hold off a while onger on the full-scale dividing and moving of perennials I do every spring.

In the meantime, here are some things you could be doing in your garden this week:

— you should have cleaned up the vegetable garden last fall, but if you didn’t, do it now! Remove dead plants and weeds, spread compost or rotted manure to prepare for spring planting.

— continue to direct sow seeds of cool-weather crops such as lettuce, mesclun mix, spinach, arugula and peas. They’ll germinate and grow when the weather is warm and stall when it turns cold. But cold weather won’t hurt them, and you’ll have spring greens as early as possible.

— start vegetable seeds for warm-weather crops such as tomatoes and squash. You can find a list of dates for starting seeds in this post.

— Weed! Dig up wild garlic and dandelions and pull garlic mustard. It’s too late to pull western bittercress, which has already gone to seed. Mustards go to seed particularly early, so it’s a good idea to pull them as soon as you recognize them. And they’re easy to pull.

— as weeds and lawn grasses begin to grow, neaten the edges of your perennial and shrub beds. It’s easier to do it now, when the weeds’ and grasses’ root systems are relatively small, than it will be once the weather turns warm.

— if you or your lawn service has sown grass seed, water several times a day until the grass is up. Otherwise you’re just scattering birdseed. And it’s much too early to fertilize the lawn. Wait until Memorial Day. Even better, don’t fertilize at all this year. I bet the grass will do just fine.

And here’s what’s left of that Norway maple–a large snag. Dead trees are excellent shelter for wildlife, so we left the trunk standing. Eventually we’ll plant a good-sized silver maple (Acer saccharinum) nearby. Silver maples are trees that were originally growing here in our sandy river-bottom soil but have been largely replaced by alien species.

Enjoy the garden this week!

Eventually we’ll disguise this snag with additional plantings. The front island will get too much sun now that the big tree is gone.

5/16/14: In the garden this week

DSCN1425

In the perennial garden, columbine and tiarella are in full bloom; native geraniums are just starting to bloom; and Canada anemones and Virginia waterleaf are showing buds. The earliest viburnum to bloom, V. prunifolium, is in full bloom, as is chokeberry (see the photo below). Other viburnums, dogwood shrubs, and ninebark are showing buds and should bloom within the next two weeks. The earliest summer-blooming perennial in my garden, Penstemon digitalis, is beginning to put up flower stalks. And all the perennials have finally emerged from dormancy.

The cooler weather, particularly the relatively cool nights, is predicted to continue this week, so we can think of ourselves as still being in mid-spring for at least a week longer. So continue with your spring gardening chores:

plant cool weather crops such as lettuce, spinach, radishes, and peas. It you have room, sow a row each week. Keep the seedlings well watered. DO NOT plant warm-weather crops (almost anything besides the ones I listed above) until sometime in late May. The nights are still quite cool.

reseed bare lawn patches while the weather is still cool, or, better yet, plant something else such as native perennials or shrubs. Lawn grasses will not grow in a spot that is very shady or very wet. DO NOT feed the lawn until Memorial Day (if you feel you must feed).

— while the weather, especially the night-time temperature, remains cool, continue to plant and divide and move perennials. Just be sure to keep them well-watered after you plant, especially if the weather turns warm and sunny.

do not do any pruning except removal of dead or diseased material while woody plants are in active growth. They are using all their energy to accomplish the vital tasks of leafing out, blooming, and setting fruit. They have no energy to spare for making scar tissue. The next window of pruning time will come in midsummer. The exception is very early blooming shrubs, such as forsythia, which can be pruned once they’re fully leafed out. Prune early bloomers in late spring or early summer to allow them time to make next year’s flower buds.

– continue to pull up garlic mustard. However, because the plant is already setting seed, DO NOT COMPOST IT. The temperature that develops in most home compost piles is not high enough to kill weed seeds. Discard the plants instead (or, if you are sure the plants haven’t been aprayed, eat them–there are many recipes for garlic mustard pesto and other delicacies on the web). This is one invasive you can really get rid of, since it’s a biennial. Pull it up this year and next year, and it’s gone from your property except for isolated seedlings from time to time.

Soon it probably be time to plant summer crops and tender herbs such as basil. Check back next week for an update. In the meantime, enjoy the garden after the rain tomorrow.

Warm thoughts

It seems like every day for the past month, the weather forecast has predicted higher temperatures than we’ve actually experienced. I think the meteorologists are as sick of cold weather as the rest of us, so they’re giving optimistic forecasts. Today, for the first time, it’s nearly as warm as the forecast said. The temperature has been rising all afternoon, and I just spent a pleasant and anticipatory half hour in the garden, surveying the damage of winter and the promise of spring.

This year’s spring cleanup will be a doozy. Leaves that usually either settle gently or get blown away were buried under two feet of snow and now form a compact layer. There are broken branches everywhere (even though I did remedial pruning whenever I could all winter). BUT . . . when I gently push some of the detritus away or just look closely, I see new growth everywhere. Perennials are starting to come up under the leaf mulch, and buds are starting to swell. I may be able to harvest some sorrel next week.

The forecast now is for temperatures in the 50s for the next ten days. I’ve been waiting for a warm spell to sow early greens, patch the lawn, and uncover the earliest perennials. Maybe, just maybe, I’ll start all of that on Sunday.
