We say it every year and can’t say it often enough. Watering of new plants is absolutely the most important part of their care!
Absolutely never depend on an automated irrigation system to meet the water needs of new plants. Automated systems usually do not provide enough water to the depth required. Nothing takes the place of human attention–frequent monitoring to make sure the plant is neither too wet nor too dry.
