Answer: You may be able to transplant them into a better draining soilmix such as a soilless mix formulated for container plants, or lift the plants, add sand throughout the original mix, and replant. When you dig them up, try to take all of the roots. If necessary, wrap the soil ball in damp newspaper and set them in the shade to keep them from drying out while you work, replant as soon as possible and water them to settle out any air pockets. If you are able to get most of the roots, they should not suffer too much this early in the season (end of May).
