There’s an old English saying, ‘Ne’er cast a clout till May be out.’ This is said to mean, don’t discard your winter clothing until the end of this month. Another interpretation is that ‘May’ refers to the hawthorn, also known as the Mayflower, and you should keep your long johns handy until the Mayflower is in bloom (probably in another week, for us).
Whatever the case, the message is that winter’s grasp has not been released until the end of this month and that’s why I never write off a plant as dead until June although this year I have serious doubts about my Buttonbush. I cannot find the slightest glint of a growth point on it. Buttonbush (Cephalanthus occidentalis) is a wetland shrub with gorgeous globe-shaped flowers that start to bloom in July. While many wetland plants (for instance, Meadowsweet, Joe Pye Weed, Spiderwort, Smartweed) do fine in dry conditions, the Buttonbush may not be so accommodating.
I recently planted some Bunchberry (Cornus canadensis), a low-growing dogwood that makes an excellent groundcover, with showy white bracts in spring and bright red berries in the fall. Various authorities state uncompromisingly that it requires moisture or it will die, so I used a method I learned from nursery industry veteran Keith Squires. I half-filled a bucket with peat, added water, came back, added more water, and repeated over the next couple of days. Keith says peat will absorb six times its volume in water so it has to be soaked repeatedly before it’s used. I dug the plant holes, laid a couple of handfuls of wet peat in each hole, added two inches of soil and then the plant. Once well covered, the peat will stay wet with the occasional recharging from rain, Keith says. It’s very important it stay wet, because when peat dries out it starts sucking in moisture, desertifying nearby soil. Regular readers will know I don’t like to use peat, but when it comes to accommodating wetland plants, a small amount will go a long way and I expect my bag of peat to last a few years. Read more
