Olive trees are associated with Mediterranean conditions, but rainfall and soil moisture vary considerably from one garden to another. When a rainy period begins, the useful question is not how often to water by the calendar. It is whether the tree’s growing medium is still wet and whether excess water can leave the root zone.
Let rainfall guide watering
Check the soil before adding water. A tree in a container may receive little rain beneath a roof, while one in an exposed garden may receive enough that extra watering is unnecessary for a time. The tree’s size, stage of establishment, pot, soil, and weather all affect its needs. Avoid leaving the mix continuously saturated.
Give water somewhere to go
Look for standing water around an in-ground tree after heavy rain. For a potted tree, confirm that the drainage holes are open and empty any saucer that holds water. If the planting site stays waterlogged, improving drainage or choosing another location may be more useful than changing a watering schedule alone.
Watch the individual tree
Yellowing leaves or slow growth can have several causes. If you suspect a root or fungal problem, ask a qualified horticultural professional to assess the tree before using a treatment. A fungicide is not a routine substitute for drainage and diagnosis.
Olive De Casa can discuss the growing conditions and care of a particular tree. Share photographs of the tree and planting area, and describe how water drains after rain.
