I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Continue to maintain moderate soil moisture and avoid overwatering since soggy soil can be deadly because it excludes oxygen from the roots. You can begin to fertilize very lightly starting sometime in April. Just make sure that the applications are not excessive or you might burn the tender roots as the fertilizer salts wash down into the soil. Regarding the variety up your tree, we don't have access to the various varieties sold in the many stores across the country.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
