Why Doesn't Nepenthes Grow Pitchers?

Nepenthes is a rather special plant, and its specialness lies in the fact that it has a unique organ——the pitcher, which can break down the nutrients inside insects and absorb them for its own use. As one of the few carnivorous plants, it is also grown by quite a few people in our country. But some people wonder: they have grown their Nepenthes for one or two years, so why has it still not grown any pitchers? Today Qinnong Network will introduce to you how to grow Nepenthes so that it produces pitchers.

From sowing to producing pitchers, Nepenthes needs at least 18 months. If the growing time has not yet reached 18 months, then it simply has not yet reached the growth stage at which it forms pitchers. If the time has been reached and it still has not grown any, then you need to consider the following reasons.

1. No plant of the opposite sex

Nepenthes is a dioecious plant, and therefore there must be two plants of different sexes for pollination to occur. In the wild, male Nepenthes account for about 70% and females for 30%. Because Nepenthes grows in low-latitude regions, where there is no obvious distinction between the four seasons, Nepenthes can flower all year round; as long as the stem of the upper pitcher can form, it may flower. If a potted Nepenthes has only one plant or several plants of the same sex, then it very likely will not be able to produce pitchers; just pay attention to pairing male and female.

2. Water and fertilizer do not meet the requirements for growing pitchers

If the growing environment does not meet the needs of Nepenthes, then Nepenthes is also not very likely to grow pitchers. Nepenthes likes a high-humidity environment with plenty of light. The growing environment must not be too dry, otherwise it will fail to form pitchers. When growing it, pay attention to watering, but do not let it become too wet and develop root rot.

Improper fertilizing can also cause Nepenthes not to form pitchers. If too much fertilizer is applied, the soil will become compacted; if too little fertilizer is applied, the nutrients will be insufficient, and it will be unable to form pitchers. When growing Nepenthes, you can apply fertilizer once every half month, but it should be a dilute fertilizer.

3. Temperature too low

When growing Nepenthes, if the growing temperature is too low, growth will stop. The suitable growing temperature for Nepenthes is between 25°C——30°C, and in winter the temperature must not be lower than 16°C, otherwise the Nepenthes plant will begin to stop growing.

In addition, when the weather is relatively hot, you need to spray water at night to lower the temperature and ensure a relatively large temperature difference between day and night, which is beneficial to the growth of Nepenthes.

4. Changing location over the long term

If the growing location of Nepenthes is changed frequently, it may also fail to form pitchers. Therefore, do not frequently change the environment for your Nepenthes. Even if your current environment is not very ideal, as long as you patiently wait for it to adapt to the surrounding environment, it will still keep forming pitchers.

The above are the reasons why Nepenthes does not grow pitchers, compiled by Qinnong Network for everyone. Nepenthes likes a hot and humid environment and is relatively suited to being grown in the southern regions of our country. If the growing environment is suitable, Nepenthes can also grow very large. Therefore, when planting, it is best to first choose a suitable spot for it to grow, and afterward do not casually change its growing environment.
