Can West Lake Longjing tea saplings make bonsai?

West Lake Longjing tea saplings can be used as bonsai. Here are the main points of cultivation:

1. Planting: spring planting in the north of the Yangtze River and autumn planting in the south of the Yangtze River. Good drainage and strong water retention should be selected for land cultivation. A sandy loam rich in humus. Pot culture was made of rotten leaf soil, sandy soil, stable fertilizer soil, or 4 parts of rotten leaf soil, 5 parts of peat soil and 1 part of coarse sand. The value of pH is 5-6.5. The planting land should choose a place where there is no stagnant water or can not be exposed to the hot sun. The potted Longjing tea is placed in a ventilated and transparent place in winter and in a shady shed or other shady place in summer. Tea Longjing is not allowed to move randomly, otherwise it is disadvantageous to its growth.

2. Light and temperature: Longjing tea is a long-day plant. The optimum growth temperature was 18-25 ℃, and higher than 35 ℃ would burn leaves. Not cold-resistant, should enter the room in winter, the temperature should be maintained at 3: 5 ℃, can also withstand a low temperature of-10 ℃ for a short time, but not more than 16 ℃ for a long time, otherwise it will promote germination and cause fallen leaves. During the growing period, you should be placed in a semi-overcast environment and should not accept excessive direct sunlight. Especially in summer and autumn, shade should be carried out, or under the trees in a sparse shade.

3. Watering and fertilization: Longjing tea has higher requirements for fertilizer and water, and both neutral and alkaline loam are disadvantageous to its growth. In the north, special attention should be paid to the acidification of alkaline water before it can be watered. The specific method is to store the rice water for 2 days, volatilize the chlorine in the water, and then add an appropriate amount of ferrous sulfate (about 0.5% of the water). The amount of water should not be too large, otherwise the roots will rot easily. The basin soil can not be dry, otherwise it is easy to make the roots shrink because of water loss, so as to keep the basin soil and the surrounding environment moist. It is better to apply fertilizer with thin alum fertilizer and water, and avoid applying thick fertilizer. Generally, after sprouting in spring, thin fertilizer and water are applied every 17 days, phosphorus and potassium fertilizer are applied in summer, and fertilizer can be stopped for about one month in early autumn.

4. Shaping and pruning: Longjing tea planted in the ground mainly cut off dry and withered branches, diseased and weak branches, cross branches and overdense branches, which obviously affected the tree-shaped branches. In addition to the above work, potted Longjing tea should also be shaped and trimmed according to personal preferences, but it should not be re-cut, because its growth potential is not strong.
