I had two peach trees planted about 4 months ago by a landscaping company. Initially, the leaves on the tree looked brown with holes in them. I now see what looks like white clear things (looks like worms) on the tree stump with more leaves getting holes and being brown. When I contacted the landscapers, they sold me a spray to use for a 7-14 day period. However, the trees are not looking better. Do they have to be replaced or is there still a chance they will be ok?

I personally like neem oil as it is also a pesticide but does not hurt bees. Here is more information on it: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
