After pruning the camellias, which are called camellia balls, not only do you have to work hard to learn the pruning techniques, but daily maintenance of the camellias is also very important, otherwise it may cause the beautiful camellia balls to wither and die. Defoliation.
Key points for Camellia cultivation and care
When cultivating Camellia, you need to pay attention to the three stages of Camellia:
The first stage is the new period of Camellia The peak period of shoot and new root growth is probably March to April. The pot soil should be dry and moist, and should be mainly nitrogen fertilizer. Here you can store the daily rice water and use it in 4 to 5 days. The effect is very good.
The second period is the camellia flower bud differentiation period, which is in late June. Fertilization at this time is mainly phosphorus and potassium fertilizer. Potassium dihydrogen phosphate, superphosphate, etc. can be sprayed. 0.1% boric acid can also be added during spraying. Boric acid can promote the differentiation of flower buds and prevent the flower buds from falling off easily. When forming flower buds, you should also pay attention to watering (reduce the amount of watering). In summer and autumn, put it outdoors for maintenance under a shade shed and avoid direct sunlight.
The third period is the transition period between autumn and winter. During this period, there is little evaporation from the roots and leaves of camellias. The soil for potted camellias should not be too dry. The humidity of the pot soil should be maintained at a moisture content of 60% to 70%. Normally. Increase leaf surface moisture. Apply potassium fertilizer appropriately in early winter to enhance cold resistance.
Camellia bulb pruning principles
Camellia pruning is usually done in late autumn before winter. First, cut off all diseased and dead branches, then trim back the long branches, and then follow your own ideas. Prune into pagoda shape, semicircle shape, umbrella shape, large tree shape, etc. Generally, it should be pruned vertically according to the type of pruning.
Camellia Shulei generally starts to be thinned out when the buds are about the size of soybeans. For strong trees, more can be left, and for less robust camellias, try to leave as little or as little as possible. We generally grow flowers for our own appreciation, so we need to see the flowers and maintain the trees well, so we should try to keep as few flower buds as possible, instead of being like flower farmers, the more flower buds the better.
According to the camellia bud soothing principle, at most one flower bud can be left on each branch. Do not leave flower buds on thin branches. However, it should be noted that when soothing Dian tea, you must be careful. You must use two hands together, one hand to protect the bud head that you want to sooth, and one hand to sooth it, otherwise it will be easy to break the buds together. . Because the branches of Yunnan tea are relatively fragile. Dian tea does not germinate much, and can leave a few more flower buds than East China tea and foreign varieties.
How to deal with Camellia buds but not blooming
Pay attention to frost protection. The suitable temperature for the camellia bud stage is 10-15℃. Cold air activity is frequent in early winter and spring, and the temperature often drops suddenly below 5°C, which can cause frostbite in flower buds and prevent them from blooming. The remedy: Place the flowers in a warm, windless place during the day and move them indoors at night; if the temperature is below 5°C, cover the flowerpot with a plastic film bag to increase the temperature.
Maintain humidity. In winter and spring, after 10 a.m. on a sunny day, spray water or mist on the camellia to maintain air humidity. Generally, watering should be done every 3-5 days on sunny days to keep the pot surface moist and not too dry or too wet. Large pots can be watered every 5-7 days. When planting camellias on the ground, you should flexibly control the spraying or watering according to the situation.
Control pests and diseases. The main pests in the camellia bud stage are aphids and rust ticks. Aphids can be sprayed with 1000 times of 40% omethoate EC, and rusty ticks can be controlled by spraying with 50 grams of washing powder, 10 ml of diesel fuel, and 10 liters of water, mixed evenly.
Generally speaking, it is relatively easy to cultivate camellia bulbs, and there are relatively few things to pay attention to when pruning them. Therefore, it is very suitable for novice gardeners to plant and practice shrub bulb pruning techniques.
