Pruning principles and maintenance points for attention of Camellia Ball

After the camellia is called the camellia ball, it is not only necessary to make more efforts in pruning, but also very important to its daily maintenance, otherwise it may cause the beautiful camellia ball to die with a large number of defoliation.

Key points of cultivation and maintenance of camellia

When cultivating camellias, we should pay attention to three periods of camellias:

The first period is the peak of new shoots and roots of camellias, probably from March to April. The basin soil should be dry and wet, and it is mainly nitrogen fertilizer. Here can be taken to store the daily rice washing water, which can be used in 4 to 5 days, and the effect is very good.

The second period is the flower bud differentiation period of camellia, which is in late June, when the fertilizer is mainly phosphorus and potassium fertilizer. Potassium dihydrogen phosphate and calcium superphosphate can be sprayed, and 0.1% boric acid can be added during spraying. Boric acid can promote flower bud differentiation and make the bud not easy to fall off. In the formation of flower buds, we should also pay attention to buckle water (reduce the amount of water). Summer and autumn in the outdoor shade under the shed maintenance, avoid direct light.

The third period is the transition period of autumn and winter, during which the evaporation of roots and leaves of camellias is less, the soil of potted camellias can not be too dry, and the humidity of potted soil should be kept at 60% to 70%, which usually increases the moisture of leaves. Appropriate application of potash fertilizer at the beginning of winter to enhance cold resistance.

Principle of camellia ball pruning

Camellia pruning is generally pruned before late autumn and winter, first cut off all diseased and dead branches, then cut only long branches, and then trim them into pagoda, semicircle, umbrella, big tree and so on according to their own ideas. generally, it should be pruned according to which kind of vertical pruning is better.

Camellia Shuli generally begins to sparse when the buds are the size of soybeans, sturdy trees can stay more, and unrobust camellias stay as little or no as possible. We usually grow flowers for our own appreciation, so we should look at both flowers and trees, so leave as few buds as possible, instead of selling as many buds as a flower farmer does.

The principle of Camellia Shuli is that each branch can leave at most one bud. Thin branches are not allowed to leave buds. However, it should be noted that the Yunnan tea Shulei must be careful, with two hands together, one hand to protect the bud head of Shulei, and the other hand to Shulei, otherwise it is easy to break the bud together. Because the branches of Yunnan tea are relatively crisp. Yunnan tea does not sprout much, and there can be a few more buds than East China tea and foreign varieties.

Treatment of camellias with buds but not blossoms

Be careful against freezing. The suitable temperature for camellia bud stage is 10-15 ℃. The cold air is active in winter and early spring, and the temperature often drops below 5 ℃, which can cause frostbite in buds and do not blossom. The remedy: put the flowers in a warm place without wind and sun during the day and move them indoors at night; if the temperature is below 5 ℃, cover the flowerpot with a plastic bag to increase the temperature.

Keep it humid. After 10:00 on a sunny day in winter and spring, spray or spray the camellias to keep the air humid. Generally, water is watered every 3-5 days on sunny days to keep the basin moist, not too dry or too wet. Large pots can be watered every 5-7 days. When planting camellias on the ground, you should flexibly master spraying or watering according to the situation.

Control diseases and insect pests. The main pests in camellia bud stage are aphids and rust wall lice. Aphids can be sprayed with 1000 times omethoate EC, and rust wall lice can be sprayed evenly with 50 grams of detergent, 10 milliliters of diesel oil and 10 liters of water.

Generally speaking, the cultivation of camellias balls is relatively easy, and there are relatively few things to pay attention to, so it is very suitable for novice gardeners to plant and practice shrub ball pruning techniques.
