Thanks, Italia.
I learned about trimming oaks this year. (I'm new to Texas, since June 2012.) I had an arborist come in to trim some big oaks that were too close to my roof. He explained how the big old trees will break because they get too heavy.
Should I fertilize now? I don't have compost I've made myself--I keep scooping it out with the soldier fly larvae for the chickens, so it is spread around the grassy areas. If I put compost on, it is the store bought stuff and I'm not impressed with any in a bag. Suggestions?
I planted some Bigtooth maples and two are not as happy as the third. I think they had more heat to deal with. Their leaves are a little yellow, but I don't think I want to give them any nitrogen at this time of year. What about some iron?
Thanks for your help. I've gardened in Saudi Arabia, the Caribbean (a challenge!), Canada and Texas, and I think the plants in Texas have the toughest environment. Not only do they have to deal with heat and drought, but also cold.
