Diabolo Ninebark leaves curling and dry
I just planted a Diabolo ninebark plant and watered the hole well, watered the ball and packing soil and watered a few times since planting 5 days ago. In the pot, leaves would wilt, but firm up after watering. The leaves were a uniform color. Now the leaves are 2 different colors, with the bottom leaves curling and crunchy. Am I not watering enough? Watered too much? Transplant shock? Thank you for your assistance.
The plant is trying to establish itself.
We could not see around the base of the trunk. Some reasons for decline include planting too deeply; too much moisture or not enough; poor drainage; were the roots teased apart so they could grow into the native soil; if you added a lot of organic matter into the planting hole you may have created a bathtub effect as water sits in the planting hole and drowns the plant. Take a look at our website for the planting process, video (explains the process), and aftercare. http://extension.umd.edu/hgic/plants/planting-process
At this point make sure it is not planted too deeply. You should be able to see the flare of the trunk where it joins the root system. If planted too deep, you may be able to lift and replant. Tease out the roots if growing in a circle within the rootball.
Plant the shrub with the top of the root ball slightly above the existing soil line. This is helpful when planting in heavy clay soils that drain poorly.
Mulch to conserve moisture, keep away mowers and string trimmers, and to keep the weeds down. Make sure mulch is no thicker than several inches and keep away from the base of the trunk. You can mulch out to the dripline of the shrub.
Check the soil moisture at least once a week. In this dry weather depending upon your soil type check the moisture every several days. Soil should be damp like a wrung out sponge. You may need to probe with a screwdriver. Water deeply and let the top several inches dry slightly before watering again. Water up until the ground freezes. Do not overwater.
