Can crab claw orchids be pruned in autumn? In autumn, as the weather gets cold, the crab claw orchid becomes active and will gradually return to normal growth. Moreover, whether the autumn management work is done well or not will directly affect the winter flowering. So can crab claw orchids be pruned in autumn?

Can crab claw orchids be pruned in autumn? 1 After entering autumn, the crab claw orchid gradually wakes up from the dormant state in summer, thus resuming normal growth. Although the crab claw orchid blooms in winter, it differentiates and even breeds flower buds in autumn. Therefore, normal watering and fertilization must be resumed in autumn.

The pruning of Crab Claw Orchid is usually carried out after the flowers wither in spring, which can save some nutrients and is more conducive to the recovery of plant growth. After a summer's suffering, after entering the autumn, the crab claw orchid can resume its growth, and it can also be pruned properly besides topdressing.

Pruning crab claw orchid in autumn can generally be combined with plastic surgery. The effect after pruning must be that the plant shape and flower shape are more beautiful. Because useless and slow-growing branches on plants will consume nutrients continuously, pruning in time can reduce nutrient consumption and help plants rejuvenate.

However, in autumn, the crab claw orchid is pruned, usually by cutting off the redundant part of the branch and cutting off 2-3 leaf nodes at the head of the branch. And pruning has another advantage, that is, if the stomata at the top of branches are blocked due to dust accumulation or other reasons, it will also affect the germination of plants and inhibit the differentiation of flower buds.

Therefore, crab claw orchids can usually be pruned in autumn, and sometimes it is very necessary. However, to grasp the degree of pruning, it is usually only necessary to cut off useless branches, especially 2-3 leaf nodes at the top of the plant. This can not only save nutrients, but also stimulate plants to sprout new branches and leaves.

Can crab claw orchids be pruned in autumn? Crab claw orchid can be pruned in autumn, when the plant is in the transition stage from dormancy to growth, and pruning will not affect its growth. In the process of pruning, it is necessary to cut off the dry and damaged stem segments of the crab claw orchid with sterilized scissors to help the plant preserve nutrients. After pruning, plant ash can be applied to the wound to help it heal.

Can crab claw orchids be pruned in autumn?

1, which can be trimmed.

Crab claw orchids can be pruned in autumn. Because the crab claw orchid will have a short dormant period when the weather is hot in summer, and the temperature will gradually decrease in autumn, the crab claw orchid will enter the growth period from the dormant period, and pruning will not harm it at this time, so it can be pruned in autumn.

2. Pruning method

In the process of pruning crab claw orchid, it is necessary to choose scissors with sharp edges and disinfect them, and then use scissors to cut off the stems of crab claw orchid with poor growth, dryness and damage to help plants preserve nutrients, or cut off the stems of crab claw orchid with excessive growth to improve the ventilation between plants.

3, wound treatment

After pruning, plant ash or carbendazim solution can be applied to the wound of hawthorn to help the wound heal. At the same time, the pruned Fructus Crataegi needs to be kept in an astigmatism environment, and only after the wound of Fructus Crataegi has healed smoothly can it be moved into a sunny environment.

4, post-management

In the later period of maintenance, unpolluted natural water and river water can be used to keep the soil moist, compound fertilizer with balanced nitrogen, phosphorus and potassium can be provided for the crab claw orchid to improve the growth speed of the plant, and pesticides can be sprayed to make the plant grow healthily.

Can crab claw orchids be pruned in autumn? 3. What will happen to Crab Claw Orchid in autumn?

We all know that the crab claw orchid will undergo flower bud differentiation and produce buds after it enters autumn, but it does not mean that it will produce buds immediately in autumn. When the temperature is high in summer, the crab claw orchid will be in a dormant or semi-dormant state, that is, it will not grow or die, which is a state of dead seedlings. When the temperature drops in autumn, it will first enter the rapid vegetative growth period (that is, the long leaf period) and then enter the budding period.

Here's a little popular science. Plants that bloom in winter, such as crab claw orchids or longevity flowers, breed buds in autumn, not because the temperature drops, but because they are short-day flowering plants. Generally, after the autumnal equinox, the day is shorter than the night, and the sunshine time in a day is gradually shortened, so that the light will stimulate it to differentiate flower buds.

As we all know who have studied geography, the sunshine time becomes shorter after the autumnal equinox, but the process of shortening is very slow, and it is getting shorter every day. Therefore, before it can be clearly felt that the time of day is shorter than that of night, the crab claw orchid is growing nutritionally, that is, the old leaves resume growing and the new leaves keep growing.

After the autumnal equinox, the crab claw orchid will slowly sprout buds. By the end of autumn or early winter, the flower bud differentiation of the crab claw orchid was basically completed, and most of the flower buds had appeared. Therefore, pruning or coring Crab claw orchid in autumn should be done reasonably in different periods, otherwise it will be difficult to bloom if its flowering branches and leaves are cut off.

Second, crab claw orchid pruning in autumn

1, rapid growth period

Some crab claw orchids will wither, wrinkle and wilt in summer (water control, shading and fertilizer stop). So summer has passed and autumn has come, and the crab claw orchid has to restore the withered leaves before it can grow new leaves. If some leaves wrinkle badly and shrink like a thin layer of paper, it is difficult to recover and it takes a long time. It is better to cut them off directly and let them grow new leaves again and grow faster.

2. Germination and incubation period

When the crab claw orchid is ready to breed buds and grow small buds, the growth of branches and leaves has basically come to an end. However, we will all find that the leaves that grow first must be full and long, and the leaves that grow later are still relatively small and short. Since it's time to breed buds and all the conditions are met, it's necessary to stop the growth of leaves, and this small leaf can also be pinched off.

This kind of small leaves is obviously much shorter than mature leaves, and it is difficult to grow buds on them in the future, and the number is relatively small. It is better to pinch it off and leave the leaves with mature nutrition to grow buds. Autumn pruning (whether cutting withered old leaves or pinching immature small leaves) should not be too large. Pinch a leaf or two is enough. Too much coring will affect flower bud differentiation.

Third, it is indispensable to promote flower fertilization.

If you want Crab Claw Orchid to grow more buds and blossom smoothly, there will be no bud elimination and bud drop. Reasonable and appropriate fertilization is definitely indispensable. Crab claw orchid has two different growth periods after autumn, so fertilization must be corresponding.

When 1. grows rapidly, compound fertilizer or fertilizer with high nitrogen and potassium content should be applied. There is a simple reason. Long branches and leaves need fertilizers with high nitrogen and potassium. Nitrogen promotes the formation of leaves and makes them greener, while potassium makes the roots and branches of plants stronger.

In particular, there is another situation. Some crab claw orchids should grow rapidly in autumn after summer, but there is one situation that is persistent and rigid, that is, they will not grow or die. At this time, it is necessary to properly apply a little high-nitrogen fertilizer to stimulate its growth, break its dormancy and let it wake up as soon as possible.

2. When the crab claw orchid enters the flower bud differentiation, that is, when we see the flower bone with small protrusions growing at its tip, it is necessary to apply high phosphorus and high potassium fertilizer at this time. Common fertilizers for promoting flowers are potassium dihydrogen phosphate, Huaduoduo No.2 and Bi Hua, so choose one of them.

These three kinds of flower-promoting fertilizers are all quick-acting fertilizers that can be dissolved in water, so they are all mixed with water at the ratio of 65,438+0,000 times, and then used to spray the leaves of crab claw orchid or pour pot soil once every 65,438+00 days and a half. You can stop until the bud grows to a centimeter long. When the bud grows to a centimeter long, it is ready to open. If we continue to use chemical fertilizer, it will accelerate the metabolism of flower buds and make flowers wither early.
