Hydrangeas watering and exposure

Hydrangea exposure

Almost all hydrangeas love a shaded exposure, although they are not particularly afraid of morning or evening sun. However, for proper cultivation, it is best to shelter them during the hottest hours of the day, especially during the summer season, to prevent direct sunlight from damaging them.

Hydrangea hardiness

Almost all hydrangeas are very resistant to frost. In any case, the most resistant varieties, which can also be grown at higher altitudes, are undoubtedly the paniculata and arborescens. The climbing petiolaris and quercifolia are also excellent choices. The greatest danger, especially for the more sensitive varieties, is actually late spring frosts, which can burn the buds resulting in the loss of blooming for that year.

Watering

Hydrangeas require abundant watering and it is advisable during the summer to water them with a certain regularity. However, waterlogging must be carefully avoided as it can damage the root system and make iron more difficult to absorb, increasing the risk of chlorosis. There is no need to be overly alarmed if the plant appears dehydrated and wilted during the hottest hours of the day. Most of the time, it will return to its normal splendor with the cool of the evening.

If the problem persists until the morning (and you also notice sunburn on the leaves), it is best to provide some shade for the plant and mulch the soil to prevent excessive moisture loss.
