Am not sure where you live but they need two things I have found out (besides good sunshine amounts), nutrients on a regular basis and dry out just a tad in between waterings. The pot should be large enough that the roots have oodles of room for,expansion and growth. The trees also require soil with good drainage and do well in loamy and sandy loam soils. The soil can range between 5.5 and 6.5 pH. You can amend your soil to reach the desired pH level, either adding sulfur to increase soil acidity or lime to lower overly acidic soil.
