When does the pineapple flower bloom?

The flowering of pineapple does not have a fixed season, and it is generally related to growth time and maintenance, as long as the growth time is more than 8 months (different varieties require different time, from 8 months to several years), the plant is strong enough (including dead old leaves). It is possible to blossom. Let's take a look at when the pineapple blossoms will bloom.

When will the pineapple blossom?

When the pineapple grows naturally with more than 30 leaves, it can blossom on its own under suitable conditions, and the flowering period is mainly in late spring and early summer. In order to make the ornamental pineapple blossom as soon as possible, most of them carry out artificial flowering, and when some festivals are approaching, in order to enable people to see colorful ornamental pineapple flowers on festivals, people carry out artificial flowering.

Artificial flowering method of pineapple

The most commonly used method for artificial flowering treatment of pineapple is to treat with acetylene saturated solution, connect the acetylene gas bottle and the storage bucket with a skin tube, and evenly immerse the skin tube with pores in water. The acetylene gas is slowly released from the bottle to the water at a pressure of 0.5 Pa, and the outgassing time of 100 liters of water is at least 45 minutes. When the water from the container has a strong smell, it can be used to promote flowers. Pour the acetylene solution into the pineapple leaf cup which has been drained, and the dosage is just enough to fill the leaf cup. It was repeated 3 times, each time at an interval of 2-3 days, and it could blossom in 3-4 months after treatment.

Notes on promoting flowering of pineapple flowers

1. The plants that have completed the vegetative growth stage should have at least 20 fully developed leaves, including dead old leaves, in order to accumulate sufficient nutrients. If the number of leaves is too few and the nutrition is insufficient, even if the flower is successful, the flower will not reach the ornamental standard.

2. Generally, it should be carried out at about 20 ℃ at room temperature. The higher the temperature is, the shorter the flowering time is, and the lower the temperature is, the longer the flowering time is, but the daily absolute low temperature below 15 ℃ is difficult to succeed.

3. Stop fertilizing two weeks before pineapple flowering treatment, only irrigate clear water, and start fertilizing after two weeks, applying less nitrogen fertilizer and more potassium fertilizer, which can prevent the formation of green spikes.

4. do not close the acetylene valve while promoting the flower, because the acetylene gas is easy to evaporate from the water. If you turn off the valve, the concentration of acetylene in the water will gradually decrease, affecting the effect of promoting the flower.
