Watering nowadays has become a priority in our nursery. We still choose to perform this task manually and even determine the amount of water each individual tree needs. In summer when we have high temperatures it is common to do this twice a day. Even our young starter material is being watered manually.
The difference is being made by how we water them:
1) Keeping the trees merely alive without constant growth meaning not enough air humidity and not watering regularly.
2) Keep trees growing constantly which requires “feeling” and knowledge.
3) It is not difficult to ruin trees by drowning them during watering.
4) And drying them out is the easiest way.
Automatic sprinkling systems do not differentiate between varieties of trees. These maples need other requirements than the juniper plants next to them.
