Then drop a drainage layer (gravel or clay balls) and complete with heather earth. All that remains is to plant your Japanese camellia, being careful not to bury it too much.
Potted camellia japonica is perfect for Japanese gardens.
Plant in the ground:
For your shrub to flourish fully, it is strongly recommended that you plant it in a acid earth. It will be able to tolerate a neutral soil, but in no case will it support limestone.
After checking that your soil has the correct pH, you can move on to planting by digging a hole large enough to accommodate the root ball. However, this should not be too buried. The ideal is that she outcrops lightly the ground.
