It is certainly not an easy task to grow hydrangeas in pots and we must be very clear about this.

Surely many people will have known both painful experiences. But finally, you can have beautiful pot-grown hydrangeas as long as you follow a series of guidelines. Here are some tips on how to care for potted hydrangeas.

The first factor to take into account is the location. Most of them will do very well in the mild morning sun, but from midday onwards, they will be better in the shade. So, we must look for a suitable place that meets this condition or simply change the site.

Not only for this reason but for example to enhance a certain space in your garden or patio, for example, it will be important a correct choice of pots. A pot with wheels or a similar device that can be attached to it will make it easier to move. They are large plants that require large pots and in the end, are quite heavy.

Hydrangeas wilt quickly if they do not have enough space. The appropriate pots for them are those of 18″- 20″ (45-50 cm) in diameter so that they have enough substrate to thrive. They must have drainage holes because hydrangeas do not tolerate waterlogging.

This is a golden rule for all types of plants and is essential in the case of hydrangeas. We will choose the most suitable variety for the climate of the place where we live.

Plant the hydrangea at the same level as it came in its pot when purchased, no deeper or shallower. And leave enough space at the top of the pot for abundant watering. The hydrangea needs a substrate very rich in organic matter. The substrate should be well compacted so that there are no air pockets.

Watering is another essential point in hydrangea care. It is better to err a little on the side of under-watering than over-watering. When the upper part of the substrate, 1″ (2.5 cm) or so, is dry, it is time to water.

Hydrangeas do not need much fertilization; in any case, we will only add some slow-release fertilizer or cured manure a couple of times a year. Certainly, never after summer if you live in a warm climate. In cool climates, you can only fertilize once a year in early summer. We should not fertilize the plant if we perceive any symptom of disease, it is better to clarify before the origin of this one.

When the flowers begin to fade, they should be cut to encourage new flowering. Finally, it should be noted that success in growing hydrangeas in pots is based on the correct choice of variety. Dwarf hydrangea varieties include Hydrangea paniculata ‘Little Lime’; Hydrangea paniculata ‘Bombshell’; Hydrangea paniculata ‘Little Quick Fire’; Hydrangea macrophylla ‘Mini Penny’; Hydrangea macrophylla ‘Buttons ‘n Bows’. They all reach a similar height, between 35″ and 71″ (90 -180 cm), but vary only in the color of their flowers and their different adaptability to different climates.
