The drought continues! Despite all the predictions and lots of cloudy weather, we received well under an inch of rain this week, so the soil is very, very dry–unusual for this time of year. So watering new plantings is a high priority. Established plants, if they are sited properly, should not need supplemental water, however.
In addition to enjoying a Memorial day barbecue, here are some things you could be doing in the garden this holiday weekend:
— water new plantings: Water the plot thoroughly before planting, and give all newly installed plants a good soaking as soon as you put them in the ground to settle them in and eliminate air pockets in the soil. Any week in which we receive less than an inch of rain (like this week and the past two weeks), 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.
— harvest early greens such as lettuce, spinach, arugula, mustard greens, and mesclun mix, plus peas and radishes.
— If you started warm-season crops indoors, set them out in the garden now. It’s finally time to set out your tomatoes, peppers, squash, eggplant, beans, and cucumbers.
— now that all perennials have emerged, move and divide plants as necessary. This is the best time to divide perennials: root systems are small and easy to handle, and plants recover fastest this time of year. But be sure to water the plot before doing any planting. The soil is very dry.
— 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 now to kill the grass. Then plant right through the dying grass and mulch.
— 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. If you reseed bare areas, be sure to water often. Better still, if you have a place where grass won’t grow, plant something that will, like shade-loving native perennials. 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. But remember: the more you water, the more you’ll have to mow!
Enjoy the garden this week!
