Good morning, thank you so much for your monthly tree advice column.
We live in the south valley and we have a couple of trees that we are uncertain of.
1.The Hawthorne- we planted the Hawthorne about two years ago and this year the leaves seem dwarfed (very small not full size). I’ve done a couple of google searches on this and all I’ve found is the drought conditions causing this. If it is the drought what can we do to recover the tree?
a.We also have very dense clay soil conditions throughout out property, when we had our septic system installed we were told we have clay at least ten feet down. Could this be causing our problem?
2.We have another Elm in another area of the yard that has the same dwarfed leaves on a majority of the leaves. We’ve noticed recently some leaves are coming in full size. However on this tree we did some over excavation on the hole we planted it in. We used a mix of compost, sand, and clay soil while planting about three years ago. Is this a result of drought or transplanting
3.Final question. We have 2 trees planted in a grassy lawn area. can we fertilize the lawn with weed and feed products? Or fertilize with regular lawn fertilizer? Or fertilize at all?
a.On that note should we fertilize our trees? If so, how often?
