Watering hydrangea - Plenty of water, but no waterlogging


Anyone who has ever dealt with the care of hydrangeas, or even cares for this beautiful shrub in the garden, knows how moisture-loving it is and that it requires frequent watering, not only in the summer. In this respect, hydrangea care in the pot is no different in any way. Here, too, it is watering, watering, watering! It is even the case that in the pot the need for water increases, because the soil is simply much less and thus dries out faster. This is especially true during the hot summer months.

Nevertheless, you should not give the hydrangea too much water. Waterlogging should be avoided at all costs. So excess water that has collected in the plate, it is necessary to dispose of, or water in such a way that none collects in the first place. As for the water itself, low-calcium is best. You can get it, for example, by collecting rainwater. Only in this way can you guarantee the acidic soil that the garden hydrangea, but of course also the hydrangea as a houseplant, loves.

You can (and should) help them out a bit by enriching the watering water with vinegar from time to time. Also, use test strips to check the pH (it should be a little below 7). Also, use rhodondendron soil instead of regular potting soil, which is sufficiently acidic, and repot every two years.

Use special hydrangea fertilizer or fertilizer for azaleas or rhododendrons, which you administer as a liquid fertilizer with the water. Once a week during the growth period is enough.
