Cutting of crab claw orchid

The temperature drops in autumn, which is a good time for crab claw cutting

Cutting steps:

1. Cut off the robust branches of crab claw from the mother plant of crab claw orchid, preferably in the same year, so that the cutting survival rate will be higher. Soak the cut leaves in carbendazim for about 20 minutes, and then dry them

2. For the soil needed for cutting, we must choose loose and breathable nutrient soil, such as perlite, vermiculite or pine needle soil

3. Spreading some rooting powder on the lower end of the dried crab claw can speed up the rooting speed of the crab claw

4. Insert the crab claw orchid into the prepared soil, put it in a cool and ventilated place, and spray some water on the soil for about 3-4 days

5. In about a week, the cutted crab claw can take root

6. After rooting, the crab claw orchid can be directly put into the basin, and then put it in a cool and ventilated place to slow the seedling for about 1-2 weeks, and then it can be maintained normally

Water plug of crab claw orchid

If flower friends think Cutting Rooting is too troublesome, they can also directly adopt water cutting to reproduce

Water plugging steps:

1. Cut the stem to be cut from the mother plant of crab claw, dry the wound slightly, and then insert the stem into the water. The lower part is about 3-5cm in the water

2. Fix the crab claw orchid in a hydroponic flask, and then put it in a place with sufficient scattered light to wait

3. Before the roots grow, change the water once every 2-3 days. If it's tap water, it's best to dry it for 24 hours. It took about a week to take root. Rooting can be cultivated in soil or in water all the time

Grafting of crab claw orchid

The most suitable temperature for crab claw grafting is between 17 ℃ - 25 ℃, so it's a good time to take advantage of the cool autumn

Grafting steps:

1. Selection of rootstocks. As a cactus grafted with rootstock, we must choose a cold resistant variety. It is best to choose a variety that will not wilt in winter, and the leaves must be plump, so that nutrition can grow enough

2. Scion selection. The scion should choose relatively old, strong and plump leaves, and then cut the lower end into a duck mouth shape

3. Prepare sharp knives, carbendazim solution and cotton wool. Use carbendazim solution to disinfect all crab claw leaves, cactus leaves and knives, otherwise it is easy to black rot when grafting

4. Make a cross cut about 1cm away from the top of the cactus, so that the inner section can be exposed

5. Use a knife to cross cut the cut surface of the cactus. The length is about 2 / 3 of the cuttings of crab claw

6. Remove the epidermis of the crab claw to be grafted, about 0.8-1cm, and remove the skin on both sides. When removing the epidermis, don't cut it too long, otherwise the wound will be exposed and rot

7. Insert the pruned crab claw into the cut of the cactus, fix it with a toothpick or clip, and then put it in a cool and ventilated place for about 2 weeks

8. After that, prepare the soil for cutting, insert the grafted cactus into the soil, pour half of the water, maintain in a cool and ventilated place for half a month, and then transfer it to the light

9. As long as careful care is taken, the grafted crab claw will soon produce beautiful flowers

Light of crab claw orchid

The crab claw belongs to a short sunshine plant. In autumn, the crab claw is given about 8 hours of light every day, and the rest of the time is put in a dark place, which can make the crab claw differentiate flower buds as soon as possible, so as to bloom in advance, which is commonly known as "closing a small black house"

Watering of crab claw orchid

Crab claw orchid cannot be watered too much, otherwise it is easy to get root rot. It can be watered once in 3-5 days in spring and autumn, and once in 10-15 days in summer dormancy. Be sure to wait until the surface of the basin soil is completely dry

Fertilization of crab claw orchid

Crab claw orchid likes fertilizer, but fertilization should be stopped in high temperature period in summer. From the beginning of autumn to before flowering, apply rotten liquid fertilizer or compound fertilizer about once a week, and apply more 0.2% potassium dihydrogen phosphate solution during bud pregnancy to promote flower bud differentiation and bloom more. When applying fertilizer, use a fine spout to slowly apply it along the edge of the basin. Don't touch the leaves, otherwise it will burn the leaves

Pruning of crab claw

1. Post flower pruning

After flowering, the residual flowers should be cut off in time. It should be cut short at the place where 3-4 stem nodes are under the flower, so as to reduce unnecessary nutrient consumption and let the crab claw bloom the next crop

2. Autumn pruning

After a summer dormancy period, the plants of crab claw begin to become messy. Pruning in autumn can not only ensure good-looking, but also avoid unnecessary nutrient consumption, so that crab claw has more nutrients to prepare for flowering

How does crab claw orchid leaf become soft

Huahua receives the most problem about crab claw orchid backstage, that is, the leaves are soft. Then why are the leaves of crab claw soft? Huahua thinks it is caused by rotten roots

Solution:

1. If the rotten roots are not too serious, pour less water and increase the light appropriately, so that the crab claw can slowly adapt to it

2. If the rotten roots are very serious, we can only change the pots

(1) Remove the crab claw from the original flower pot, and then clean up the soil on the root system

(2) Find a pair of sterilized scissors, trim all the old and weak roots on the root system of crab claw orchid, soak them in carbendazim solution for about 20 minutes, and then take them out and dry them in a cool and ventilated place

(3) Prepare loose and breathable nutrient soil, put the dried crab claw back into the basin, then pour it once for water penetration, then put it in a cool and ventilated place for about a week, and then transfer it to the sun
