Panicle hydrangeas are among the most popular and beautiful hydrangea species and can be found in numerous gardens, which is partly due to their ease of care. However, in order for the panicle hydrangea to produce a sea of flowers, the right care strategy is of great importance. Even the wrong location can cause the plant to wither and die. To prevent this from happening to you, we would like to give you a few tips on caring for panicle hydrangeas.

Panicle hydrangea care – Which location is best?
Ask yourself, ” which hydrangeas tolerate sun “? Panicle hydrangeas do feel very comfortable in a sunny to partial shade location, but you should keep in mind that summers have become much hotter in recent years, making the plants more at risk of drying out. For this reason, the location should be determined not only by how sunny it is, but also how often you can water the plant. This type of hydrangea can certainly survive shorter periods of drought. However, regular watering is still the better decision when it comes to proper panicle hydrangea care. Also, make sure that the hydrangea is protected from the wind.
Planting the hydrangea bush
Once you have found the perfect location, you can plant the panicle hydrangea. Spring is especially good for this, but only when frost is no longer expected. If you have missed this time of year, it does not matter. You can make up for it until autumn. However, it is important that the flowering shrub is well supplied with water from the beginning. Therefore, start by removing the root ball from the pot and then place it in water for a longer period of time. This will allow the plant to fully soak up enough water.
Dig a hole twice as large in diameter as the root ball, place the plant in it, and refill the hole with soil (and compost if needed). You can protect the young plant from drying out by covering it with a layer of mulch that can retain moisture.
Fertilize panicle hydrangea
So, abundant water is very beneficial for proper panicle hydrangea care and its lush flowering, but the water should not accumulate, otherwise the roots will rot. Therefore, make sure that the soil is permeable and enrich it with nutrients, because hydrangeas need a lot of them. If your garden has a rather nutrient-poor soil, enrich it with compost or mature manure already when planting and spread a layer of organic fertilizer under the mulch layer (e.g. horn shavings).
Otherwise, the shrubs do not need much fertilizer: once in the spring, before they sprout, organic fertilizer can be incorporated, which will be perfectly sufficient for the season. An exception, however, is the panicle hydrangea in the pot . If the plant is grown in a pot, the need for fertilizer is also higher. In this case, use special liquid fertilizer, which you administer regularly until the beginning of September (frequency should be noted on the package).
Your panicle hydrangea gets yellow leaves? This may be a sign that it is suffering from a nutrient deficiency.
Properly prune the lush flowering shrubs
How, whether and when to cut back hydrangeas depends mainly on the variety. Some form buds immediately after flowering, and if you remove the branches in the fall, the new flower will fail. Fortunately, this is not the case with panicle hydrangeas. How should you properly prune the panicle hydrangea?
When to cut panicle hydrangea?
The best time to cut back your panicle hydrangea is in the spring, and here you simply shorten the shoots by about a third. The cut is then made directly above the respective pair of buds. Try to maintain a certain amount of topiary by shortening the shoots from the inside to the outside. In this way, light can also penetrate better into the interior. This pruning time is also just right to remove dead plant parts as well as shoots that are growing weak and thin.
Wintering panicle hydrangea
These hydrangeas are extremely hardy, so you can expect to survive the cold winter without any problems. However, this does not yet apply to the particularly young plants. With them, it may well be necessary to dig them up in the first year or two and overwinter them in a milder place.
Older specimens, on the contrary, have no problems with frost, ice and snow, and even in the tub they will not freeze to death, if you then protect them with special mats and place them in a sheltered place. In this case, a house wall that radiates a certain amount of heat is recommended. It is also important that the pot is then larger than 50 cm in diameter. Small pots, on the contrary, place in winter quarters, for which you can choose the garage or basement, provided that they are not too dark (then provide them with a plant lamp).
During the winter, make sure that the plant does not dry out. For this purpose, water it from time to time.
