I used to recommend that newly planted trees in the landscape should be thoroughly soaked every other week or so in the hot growing season and maybe once a month in the cooler seasons, all to be done in addition to regular watering of the grass areas or planting areas surrounding of the trees. If trees are planted properly and watered thoroughly and properly additional soakings may not be needed. Obviously, rain will alter this schedule.

Once trees are established, a regular watering of the surrounding planting areas is normally enough. During periods of extreme drought, the soaking procedure may need to be used again on introduced trees.

On the other hand, adapted trees, planted properly and grown under an organic program will have huge root systems and healthy populations of beneficial mycorrhizal fungi on the roots. As a result, those trees will have the ability to access water and nutrients from the soil even in the harshest of conditions. If native trees are used, even the summer watering may not be needed.
