Sharing hydrangeas: This is how a hydrangea turns into two perennials
If a hydrangea has become too big, you can split the small shrub and put the two smaller plants back in a new location. However, this work requires some strength and time, as the hydrangea inside the root ball develops a compact centerpiece that can only be separated with a saw.
Digging up the old hydrangea
Very large hydrangeas can be shortened by about a third before this action. Note, however, that you then often have to do without the attractive floral decoration in the following growing season, as most hydrangeas create their flowers already in the previous year.
Follow these steps:
The sharing of hydrangea
Then saw through the hard center of the hydrangea with a sharp saw. To prevent germs from entering the plant through the open cut surface, thoroughly clean the blade before doing this work.
Then it is recommended to dust the interface with charcoal powder. To prevent it from drying out, wrap the rootstock firmly with burlap.
Planting at the new site
The planting hole should be much larger than the roots of the split hydrangea, so you can spread them freely in the planting pit when you insert them. For heavily compacted or loamy soils, it is advisable to apply a drainage layer of coarse gravel and sand before inserting the hydrangea.
When planting large hydrangeas, it will be helpful if a second person holds the plant in alignment as you progressively fill substrate into the planting pit. Take care of the soil and water the hydrangea well. Especially in the summer, the split and reacted Hydrangea must be watered regularly, so that it roots well and takes no damage.
Tips & Tricks
Mix some of the soil from the old planting spot under the substrate to fill up the new planting hole. The hydrangea then grows again very quickly.
