I have three in-ground plants in holes…each filled with 1.5 bags of coast of Maine Stonington blend soil. Hole sizes are about 15 gallons dug in packed sandy soil. Problem is plants got so big and healthy so early (in ground May 4) they need water about every other day (noticeable leaf drooping when thirsty) because I think the roots have filled the soil area and have reached the packed sandy walls of the holes. It’s mid July in NE Massachusetts with many hot days to come. Should I:
- continue to water and feed every day or two till end of season?
- cover the soil at base of plants to minimize evaporation?
- try to soak the sandy areas around the holes to prevent plant water from migrating to dry sandy surroundings?
