How to propagate hydrangeas by apical cuttings? Step by step!
Hydrangeas are easily propagated by apical cuttings. It is best to perform this procedure in June.For seedlings, we use flowerless tops of this year's shoots with 4 leaves (they should be about 15 centimeters long), remove the two lower leaves and cut the top of the shoot.Cut the remaining leaves in half to reduce the evaporation area . Fill a litter box or a flat pot with fresh soil for cuttings (a special substrate or peat), gently tamp the substrate.
Using a pickup, make vertical holes in the substrate, into which we put the seedlings, so that the traces of the lower leaves are underground.Then cover the container with a glass or plastic shade (it can even be a jar), or put on a cap made of a transparent foil bag.
The hydrangea seedlings should be placed in a bright position (however, it should not be exposed to direct sunlight), with a temperature of around 20 ° C. There must be high humidity under the lampshade. Roots and new leaves usually develop within 2-3 weeks. We plant hydrangeas only when they are well rooted.
Winter cut as a way to make beautiful flowers
The best time to trim hydrangeas is February / March, mainly due to the fact that faded inflorescences are a natural protective mantle that protects plants against frost. At the garden hydrangea, cut the dry flower balls over the first pair of green buds.
This treatment will cause flowers to develop from them.When cutting, we should also remove all stems that are frozen, weak and tangled. The same is done with the Sargenta Hydrangea sargentiana hydrangea, the sawn Hydrangea serrata, as well as the oaky Hydrangea quercifolia.
Bouquet hydrangea Hydrangea paniculata and bushy Hydrangea arborescens set their buds after winter, so in early spring they can be trimmed even very low.Cut last year's shoots, leaving only one he althy pair of buds on them.Such a cut stimulates the plants to quickly rebuild the crown.
