Japanese Camellias (Camellia japonica) have an exceptional life cycle: they flower in late summer or late summer and open under glass in the winter months.
So that they have enough strength for their lush pile, the pot should be big enough. If the roots already pass through the earth so densely and densely that they press against each other, the supply of the plant falters - despite constant watering and ten to fourteen days of fertilization. The time has come to repot your camellia, you recognize above all by the fact that on the surface of the pot bale, the roots are visible. Younger camellias are planted every two to three years, with older plants the rhythm is between five and six years. The best time to repot camellias is autumn, starting around the beginning of October. Camellias go through a period of rest in August and September, when they should also be less well watered. From October or November, they will start with a new growth spurt in the upcoming flower season.
Camellias need acidic, airy humus soil
Place the flowering shrubs in a new planter, about five centimeters in diameter larger than the old planter. It should also be at least as deep as it is wide. Camellias are flat-pollinated, but the larger earth volume makes it easier to ensure a steady supply of water. Also make sure there are enough holes in the bottom of the pot and drill two or three more if necessary.
Rhododendron soil is best suited as a substrate because camellias have very similar soil requirements. It should be low in lime, acid, rich in humus and well drained. When it comes to potting soil for Rhododendron in the field, you should give a part of coarse building sand or lava chippings on three parts of ready soil. This achieves higher structural stability and permeability.
Although camellias need even moist substrate, but are also very susceptible to waterlogging, the lower quarter of the pot is filled with a drainage of expanded clay
The camellia is carefully pulled out of the old pot at the branch base, which is usually relatively easy, as camellias, unlike many other potted plants, do not have a particularly unruly root system. If the bale is too tight, simply water the plant thoroughly and wait about an hour. Then he can usually solve easily from the pot.
Now fill a new drainage layer and some fresh substrate as described in the new pot and put the root ball of the camellia in the middle - so deep that the surface of the bale is about one to two fingers wide under the pot edge. The root ball is not loosened up with your fingers before, as this causes the sensitive camellia unnecessary stress.
Camellias are not suitable for warm living spaces, as they throw off their buds here. You need a bright and cool place
Camellias are sensitive to water hazards
When the plant is upright and centered in the new pot, refill the substrate on the sides to the top of the bale and gently compress it with your fingertips until the pot is filled all the way up to the top of the old pot bale. Now the camellia is still thoroughly poured and brought back to its old place. If you want to resettle the plant, you should do so right after repotting. As soon as the flower buds are swollen, the plant reacts very sensitively to a change of location and easily sheds the buds.
Camellias feel most comfortable in the winter in an unheated greenhouse, because they love a cool and humid, draft-free environment. Dry heating air, on the other hand, does not like it very much. Do not use a coaster for the new pot. Although camellias appreciate a consistently fresh to slightly moist substrate, they are also extremely susceptible to stagnation. If you need the coaster to keep the floor from getting wet, simply place the pot of your camellia on small clay feet.
