Have you ever turned down a friend’s offer of free plants because you didn’t know where to plant them? Or have you missed an opportunity to move plants from one home to another because you didn’t know how to care for them? If those occasions arise again, consider parking your trees, shrubs and perennials in a temporary trench. That way, you can keep them alive while you prepare a more permanent location for them.
I recently sold my Denver home to a developer. It’s not something I wanted to do, but because my house had severe mold issues and was sitting on valuable land, selling the house for a scrape was the most sensible option.
Fortunately, the builder told me that I could take all of the landscape plants with me. That, of course, wasn’t feasible. So I gave many of the plants away to neighbors so my babies could live on in the neighborhood. There were quite a few plants, though, that I took with me—stalwarts, such as Genista lydia, Isanti dogwood, serviceberry and Cheyenne mockorange.
I moved the plants temporarily to my sister’s home in Windsor, CO in late February, which is just about the worst possible time to move plants. I dug a trench about 1 foot wide, 25 feet long and 5 inches deep. The ground was frozen, so the clay soil came up in massive, solid chunks. I then placed the plants in the ground, preserving their root balls as best I could, and replaced the soil chunks, piling them around the root balls. Needless to say, there were all kinds of air pockets around the roots—not a good situation. But as the weather improved and the soil softened, I began filling in the air pockets.
It’s now late March, and the plants are starting to bud out and behave normally.
Is this a good long-term situation for the plants? Absolutely not. But for the 2 ½ months until I move to my own place and transplant them, they should be fine. Even my corydalis, which prefers shade, is hanging in there, putting on new growth in the sunny trench. I planted my ground covers in an area of the trench that’s about an inch below grade to help them retain water in Windsor’s dry, windy climate.
I water the plants every other day. It’s a good idea to keep them mulched for water conservation, weed prevention and soil temperature moderation. Dig your trench a foot or so deep, if the soil’s not too hard, to provide maximum room for roots. And try to move your plants when they’re not in bloom, so they can focus on growing roots instead of producing flowers.
The next time someone offers you plants or you move to a new home, don’t leave beloved plants on the table simply because you don’t have the perfect spot for them yet. Dig a trench to create a small parking lot. Chances are, your plants won’t mind, as long as they don’t have to stay there for more than about 3 months.
