|OK, I'm thinking of cutting down 1 of my 3 crape myrtles that is about 15Ys and replacing it with a 3Y Peach Tree that has been growing in a 23
|Cutting down a crape myrtle isn't the best approach. If the roots are still alive they will send up suckers in an effort to replace the lost leaves (trees need leaves for photosynthesis). A better way would be to dig up the crape myrtle, roots and all. Once you've removed the roots you can amend the soil with some organic matter and then plant your peach tree. I don't think the crape myrtle will have changed your soil's pH but you can test it with a pH test kit. If it falls withing the neutral to slightly acid range (6.0 to 7.0) your peach tree will be happy. I don't think your peach tree will suffer too much stress if you plant it when it is dormant. The roots will settle in and your tree will be ready to grow in the spring. Hope this answers all your questions.
