Q.Fertilizing dogwood when planting
So am planting this dogwood in November fall in chicago area. ..jus wanted to knw if I need to fertilize it or use any organic matter for better growth …so the plants root r strong enough to survive winter…
Fertilizer should not be applied directly in the planting hole, because fertilizer can burn the tree's roots. Instead, you can add fertilizer the following spring:

Compost can be mixed in with the soil around the tree, but also shouldn't be used unmixed in the planting hole. It is also fine to not add any compost or fertilizer.
