Why do orchids grow leaves and not bloom for years

Winter is a good time for many orchids to breed flower buds. Those who have long flower buds are happy. They don't get tired of watching them ten times a day. Without all kinds of anxiety for long flower buds, they can't see flower buds twenty times a day. How come your orchids grow leaves and don't bloom for years? For answers, read on.

1. Determine the variety

If you want orchids to bloom, you must first determine the species of orchids. Some flower friends don't know much about orchids. When they buy them, the seller says what variety they are, but in fact they may not be. For example, if you want to buy molan, the seller sells you Whelan. If you raise Whelan according to the method of maintaining molan, it will not bloom. Because black orchid flowering does not need vernalization, normal maintenance can open, and white orchid flowering needs vernalization, not vernalization is unable to bloom. Therefore, it is very important to determine the variety of orchids. The growth habits of different varieties are different. Only when the maintenance method is right for its temperament can it bloom normally.

2. Determine the flower bud differentiation time

After determining the variety of orchid, we can roughly determine the flower bud differentiation time of orchid, so as to adopt some means to make it successfully complete flower bud differentiation, so as to have the basis of flowering. For example, the flower bud differentiation in Chunlan, Jiangsu and Zhejiang provinces is about between summer and mango seed, while in northern areas it will lag half a month to 20 days. When spring orchid is about to enter flower bud differentiation and has entered flower bud differentiation, we can apply a little phosphorus and potassium fertilizer according to weather conditions, increase light, strictly control water, and ventilate more to promote flower bud differentiation smoothly. If water, fertilizer and light are not properly managed during the flower bud differentiation period of orchids, flower buds cannot differentiate or differentiate incompletely, thus losing the flowering foundation, and no matter how hard they try later, they are all useless. Different varieties of orchid flower bud differentiation time is also different, find their own orchid flower bud differentiation time, pay special attention to it, flowering foundation will have.

3. Conservation and management during reproductive growth period

From the beginning of flower bud differentiation of orchids, it is to change from vegetative growth to reproductive growth. Fertilization should also include nitrogen fertilizer or nitrogen, phosphorus and potassium balanced fertilizer gradually biased towards phosphorus and potassium fertilizer to promote flower bud growth. If phosphorus and potassium are insufficient during reproductive growth, flower buds may not grow even if they differentiate. In addition to fertilization, light should be gradually increased during reproductive growth stage, especially after autumn, the temperature gradually decreased, and sufficient light was a necessary condition for flower bud to germinate smoothly. If you raise orchid varieties need vernalization, when the flower buds grow to two or three centimeters, obviously slow growth or stagnation, you can carry out low-temperature vernalization, vernalization temperature between 5~10, vernalization time should not be less than 40 days, so that flower buds can be successfully taken out flowering.

In addition to the above three points, the number of Chinese orchids less than three is also unable to flower, at least one pot must have more than three false bulbs to have the possibility of flowering. Many flower friends 'orchids do not grow flower buds for several years, mostly because of maintenance problems, improper management of flower bud differentiation period makes flower buds unable to differentiate, or after flower bud differentiation, do not pay attention to fertilization flower buds can not grow, etc. If you want orchids to bloom, you must pay attention to them from the flower bud differentiation period, and don't wait until they enter the flowering period to think about ways.
