In contrast to farmer's and garden hydrangeas, panicle hydrangeas are considered to be sufficiently hardy to be planted in regions with a harsher climate. In addition, many varieties reach a considerable height and width, whereby Hydrangea paniculata, as the panicle hydrangea is botanically correct, can be limited by pruning measures.

Panicle hydrangeas in tubs need to be watered regularly

The right planter and substrate

Pot hydrangeas need a planter with a diameter of at least two-thirds the diameter of the plant, and you shouldn't skimp on the soil either. Good substrates are characterized by the fact that they are evenly crumbly and store moisture. They contain a sufficiently high proportion of clay minerals and high-quality peat. Rhododendron soil is best suited.

Fertilize potted hydrangeas regularly

Ready-to-use substrates also contain stored fertilizer and thus all the nutrients necessary for plant growth. Additional fertilization is therefore only necessary six to eight weeks after planting. After that, it makes sense to use liquid special fertilizer for ericaceous plants. Fertilize your potted panicle hydrangeas about every 8 to 14 days.

Pour panicle hydrangea properly in the bucket

Since the root space of all plants that grow in boxes, pots and tubs is always limited, they must be watered regularly. Otherwise, the root balls will dry out quickly. Daily watering, also in the morning and evening in the summer heat, is an absolute must so that your panicle hydrangeas are in top form on the balcony and terrace.

Instructions for watering hydrangeas

Check the surface of the substrate before pouring. If it has already dried, it is high time to water it. Water generously but slowly - this way the soil cannot be washed out. Excess irrigation water runs out through the drainage holes on the bottom. If you have coasters under the buckets, pour off the water that is in them. Panicle hydrangeas are very sensitive to waterlogging.

Cut panicle hydrangea

Panicle hydrangeas bloom on one-year-old wood and can therefore be pruned back vigorously in spring before they sprout. This is actually very useful, because the cut stimulates the growth of new shoots and thus the formation of flowers. Even after flowering, the shoots can be cut back a little. Repot either in spring or after flowering in autumn.

Overwinter panicle hydrangea in a bucket

Pot hydrangeas can be outdoors between March and November. Panicle hydrangeas can tolerate a few minus degrees, but should not be exposed to the cold for long periods of time. The problem with potted plants, even if they are actually hardy, is that the root ball freezes much faster than in the bed. Therefore, the plants must overwinter in a frost-free, but cool and bright place.

tips and tricks

The dwarf varieties “Bobo” and “Dharuma”, which remain quite low, are ideal for containers, but also larger varieties such as “Phantom” or “Vanille Fraise”.
