Reasons Why Bougainvillea Does Not Sprout and the Correct Way to Handle It

Flowers & Gardening 0 views
Many gardening enthusiasts find that their bougainvillea does not sprout, which gives them a real headache. How should this problem be solved? We mainly look for the cause from the following three aspects and take corresponding measures: the first is temperature, and if it is unsuitable, adjust it to the range of 15°C-30°C; the second is whether the roots were damaged during transplanting, and if they were damaged, adjust the environment around it and place it in a bright, well-ventilated spot; the third is whether it has been watered too much, and if there is too much water, reduce the amount of watering somewhat.

1. Temperature problems

(1) Specific cause: As we said above, this plant is native to the tropics. So it needs a relatively warm environment. Specifically, the suitable temperature for its growth is around 15 to 30°C. However, it also varies with the change of seasons. From May to September, when growth is fast, it is 19 to 30°C. From October to April of the following year, it is 13 to 16°C.

(2) Solution: If it is a temperature problem, then we have to "treat the disease accordingly." For the various provinces in the south, open-field cultivation is fine. However, for the more northerly regions, the temperature conditions generally cannot reach the requirement. Therefore, it must be grown in a greenhouse. If it is potted, then when the temperature is low, it must be moved indoors in time. No matter where it is grown, try to keep the temperature within the range suitable for it.

2. Root damage after transplanting

(1) Specific cause: This situation refers to plants that have just been transplanted. We all know that during transplanting, the roots of the plant are easily damaged. If they are damaged, then it may also temporarily fail to sprout.

(2) Solution: Adjust the environment around it and place it in a bright, well-ventilated spot, such as a balcony. As for watering, remember to water when the soil has dried out completely. In addition, you can also spray some water on the leaves.

3. Watering problems

(1) Specific cause: Although it relatively prefers moisture, it still cannot be watered too much. If there is excessive water, then the roots may rot from being soaked for a long time. Then, naturally, it will not sprout.

(2) Solution: If this is the case, then the amount of watering must be adjusted. It itself is relatively drought-tolerant, so just water after the soil has dried out completely.
