Answer:Redbuds are well adapted to many soil types except to permanently wet ones; he also specifically indicates that they tolerate a wide range of pH, so it is unlikely that you would need to do anything drastic to your soil in order to get these trees to grow. (They are in fact native over a wide range of climates and conditions.) He does point out that they should be kept vigorous by regular watering and fertilization. The amount and type of fertilizer would be determined by the results of some basic soil tests; your county extension (223-8627) should be able to help you with the tests and interpreting the results. However, in early spring you could apply some compost and/or a complete fertilizer such as 5-10-5 in granular form broadcast around the root zone of the plant according to the label instructions.
