Many of the different varieties of yellow elders can be treated in the same way.
Give yellow elders a minimum of 6 hours of sun every day. If the shade of trees and plants is a problem for the plant, trim them back when you can. If the plant is in a shaded area the yellow elder won't bloom as beautifully or grow as large and upright as it does in more light.
Create a 1- two-inch to 1-inch thick layer of compost in that area around the yellow elder, if the soil isn't draining properly. Yellow elders don't like damp roots and need well-drained soil for them to flourish.
The plant should be watered only in dry, hot weather, placing about 1 inch of water near the base of the plant. A lot of water could cause mildew, rot, or other harm to the yellow elder. It generally thrives on rainwater alone.
