There wasn’t much “structure” to the root systems of my young fruit trees when I planted them in the fall. They’ll need plenty of water as they come out of dormancy this spring.
I’m poised to plant my small kitchen garden, having finished late-winter pruning and grafting in my fruit trees. I’m poised, but holding. March teased early with some very warm days, but then plunged into barely-tolerable cold.
The soil has thawed, so a more rugged gardener could have planted peas, lettuce, spinach, and other cold weather crops by now. I tend to wait until April for those, and sometimes am simply too busy to plant them until late April. But this year there’s something else that’s very important for me to do in my garden: water young perennials.
Fall Planting Time Bombs
Back in mid-Autumn, I argued in this blog that you should plant fruit trees in the fall (this goes for most perennials, but if they’re not going to feed you, don’t waste your energy planting them). I shared my experiences of trying to find fruit trees at local nurseries, I explained that I ended up buying via mail-order, and I showed how I planted my young trees in mid-November.
Among the advantages I listed for planting perennials in autumn: you don’t have to water, and you can omit fertilizer. Dormant plants aren’t demanding.
Come spring, those young perennials emerge from dormancy and require the creature comforts you denied them in the fall. If you had plenty of rain or snow over the winter, your soil will thaw and be moist; your perennials will be happy. However, if your neighborhood is emerging from a dry winter, your perennials may awaken to desert-like conditions. This is especially bad for the young ones.
What’s more, even if your ground thaws wet, you need to make sure the young plants don’t dry out along with the soil. Unless you’re experiencing substantial seasonal rainfall—or massive snow melt—you should start watering when the ground thaws.
How Much Water?
In early spring, water deeply once or twice a week (again, don’t water if Mother Nature is doing a good job of it). As plants (any plants—not just the perennials you planted in autumn) emerge from dormancy (you see leaf buds plump up), increase your watering to once daily unless the soil is obviously saturated.
When you plant perennials, you should soak them till the soil can’t hold more water. This helps you work out air pockets and get the soil up against young roots. Subsequent watering needn’t saturate the soil. Your goal is to keep everything damp, not to maintain a mud pit around your tree.
When leaves emerge and you see vigorous growth, cut back the water to two or three times a week, and keep it up until fall. Skip watering if there’s a decent rainstorm.
Especially if you planted bare root trees in the fall, they need a lot of moisture in their first year to help them develop strong root systems. But temper daily watering: the point of planting in autumn was to reduce the amount of water you had to provide. Especially in March and April, the soil may stay wet for several days between watering.
It’s good to provide fertilizer as your young fall plantings wake up in the spring. Best of all, mulch with compost (but don’t let the compost rest against the plant). If that’s not an option, provide a light feed of 10-10-10 chemical fertilizer.
For my older fruit trees, I’d always driven holes in the ground with a crow bar, and then filled the holes with fertilizer. A friend who runs an orchard told me he prefers to broadcast fertilizers on the surface and let them dissolve into the soil. For young trees, just dust fertilizer on the loose soil around the tree trunk—a small handful at most. With all the watering, it’ll soak in quickly.
