The growth of Picea crassifolia is closely related to light, and too strong or too weak light will affect its growth. When the light is too strong, especially when the temperature is higher than 30 degrees, the color of the leaves of Hupilan will fade and the growth will slow down. Even under the strong light, Hu Pilan didn't grow at all, as if he were asleep. When the light is too weak, Huperzia serrata, which has weak photosynthesis, grows slowly or has a long Yi Bai, and its leaves are narrow and thin, easy to be discounted, dark green and dull. In late autumn, winter and early spring, the tiger orchid can be maintained in a place with direct light. In late spring and early summer, you can try to keep the tiger orchid in a place with bright light and no direct light.
The growth of spruce is also closely related to fertilization. Insufficient fertilization or long-term non-fertilization, slow growth, low new leaves. When the lowest temperature is higher than 15℃ and the highest temperature is lower than 30℃, the fertilizer should be applied every fifteen days, and the fertilizer property is preferably nitrogen fertilizer or compound fertilizer with balanced nitrogen, phosphorus and potassium. It is best to have a decomposed organic fertilizer, which can not only supplement the nutrients needed for growth, but also prevent the soil from hardening. The small pot of Hupilan is changed once a year. When changing the pot, some organic fertilizer is added to the bottom of the pot, which will be of great help to the growth. It's whimsical to let the tiger orchid grow taller without fertilizing it for a long time. Fertilization must be done in the peak season. Don't hear that it doesn't like chemical fertilizer, but doesn't like thick fertilizer and raw fertilizer!
The growth of Euphorbia humifusa is directly related to the quality of root system. Good roots grow fast and leaves grow wide and fat. Roots grow slowly if they are not good. There are three main reasons that affect the root system of Picea crassipes: First, the pot is too small for the root system to grow. One is excessive watering, root aging or capillary root rot. The last one is soil hardening, and the roots can't be stretched out. The hardening of small pots and soil can be solved by changing soil. Small trees should be changed every year, and big trees should be changed at least once every three years. The problem of watering is the biggest headache. Dry with less water, and waterlogging with more water. I suggest you water the tiger orchid, otherwise it will dry and not be waterlogged. Hupilan is drought-tolerant and not waterlogged. It only grows slowly when it is dry, and it is more troublesome when it is waterlogged.
If there is no problem with light, fertilization and temperature, and the tiger orchid at home is not high, turn over the pot and change the soil to replant it, and it usually takes one month to one and a half months to resume growth.
