Late September.

I planted 2 pear trees a few years back in the fall (after September). It was fabulous, I barely had to water them and it rained a lot and they are beautiful trees now. I suggest waiting until September when it cools down and starts raining a lot, we are having a dry/hot spell right now and I would not do it now. An alternative is planting in the early spring, when we have similar conditions- very rainy, fairly cool. But in that case you would probably have to water during dry spells in the summer.

I've always heard late summer/early fall is the best time to plant trees. This would allow them to establish during the fall and be best prepared for a hot summer. When I Google this, I read a variety of responses, all which are based on regions, but nothing I would consider reliable.

So, I wanted to ask here - if there is any suggestions on when I should plant?

For reference, I'm looking to plant 3-5 large Leland Cyprus (probably 30 gallon tubs and already 20 feet tall), and a few crepe myrtles. The lawn does have a sprinkler system.

Thanks.
