Potted pitaya planting method
DIY Pitaya D Bonsai Practice
Planting flow chart:
1. Choose fresh pitaya. After cutting, scrape off the pulp of pitaya with a spoon. Those small black particles are the seeds of pitaya.
2. Put the pulp into a large bowl, soak it in water, and gently screw out the seeds from the pulp by hand. Keep soaking all night.
3. The next day, put the pulp into a gauze bag, filter and knead it, then put it in clean water and squeeze it out. This process has to be repeated many times before the pulp and mucus stuck to the seeds can be completely separated.
4. Use a filter to control the water content of clean seeds for later use.
5. Prepare a cup with a layer of coarse sand at the bottom to prevent water from entering.
6. Mix the culture soil with water until it is wet but not dripping, then put it in a cup and gently compact it.
7. Press the biscuit mould 1/3 into the soil.
8. The outer ring is paved with fine white sand.
9. Spread the dried seeds evenly on the soil surface, and then spray them back and forth with a watering can to make the seed surface moist.
10. Cover the mouth of the cup with plastic wrap and put it on the bright windowsill, waiting for germination. Spray water with a watering can every two days to keep the soil and seeds moist.
1 1.5-7 days later, new buds will grow, and the plastic wrap can be removed at this time. Let the small potted plants gradually receive mild sunshine and spray water with a watering can every 2-3 days.
After 12.3-4 weeks, the cotyledons of pitaya spread out and were full of green. There is no soil to see at this time, just like laying a rug. But thorns like cactus take at least 3-4 months to grow.
Tips:
The optimum germination temperature of pitaya seeds is about 25 degrees.
A medium-sized pitaya seed can at least be made into a small pot like 10, and just pick the seeds according to your own needs.
To choose culture soil with fine particles, you can also use commercially available sowing soil instead.
Be sure to remove the pulp and gum attached to the seeds, otherwise mold will easily grow when sprouting.
To make a small potted plant, the seeds should be spread densely, especially at the edges, otherwise it will be scattered loosely and lose its aesthetic feeling.
Because the cup has no bottom hole, so don't water it directly with the kettle, so as not to water it too much. Just spray water with the watering can once every 2-3 days.
Correct pruning method of potted pitaya
First, trim the seedlings.
Pruning of potted pitaya should start from seedling stage. Because there are many upward branches, nutrients and water will be too scattered if they are not pruned. In this way, all the upward branches are relatively uniform, but there is not enough ability to blossom and bear fruit, so appropriate pruning benefits should be carried out. When pruning, one of the strongest branches should be kept to continue to grow, and all the other lateral branches should be cut off, so that nutrients and water can be concentrated on the strong branches left, laying a good foundation for flowering and fruiting. Moreover, pruning is a continuous work, which is carried out once every 10 day.
Second, plant pruning
Potted pitaya can be capped when the pot surface is about 10 cm long. Here, topping is not a single coring treatment, but a sharp knife is needed to cut the top flat to keep the wound smooth. Topping should be carried out at a height of about 5-6 from the basin surface, and the main branches can be interrupted horizontally. If you pinch the top by hand, it is not easy to cut it off, which may lead to serious injury to the trunk and affect the growth; Secondly, even if the tip can be cut off by hand, it will leave a lot of stubble, which is not conducive to wound healing.
Third, trim flowers.
When potted pitaya blooms, it is necessary to keep strong flowering branches as much as possible to ensure the fruit, but the accidental side branches of flowering and fruiting branches should be cut off purposefully and selectively. This can reduce unnecessary nutrient consumption, but more of the saved nutrients are concentrated and transported to the fruiting branches, ensuring that the fruit can get more nutrients. During operation, the position about 15 cm from the tire periphery or even the root can be cut off, so that the side branches at the tail of the branches should be cut off. At the same time, when the bearing branch is about 1.3 meters away from the tire periphery, it should be cut off, so that nutrients can be transported to the fruit more intensively, and the fruit expansion and quality can be effectively improved.
Water and Fertilizer Maintenance and Management of Potted Pitaya
Pitaya is a drought-tolerant plant. It would rather be dry than wet, and water it when it is dry. Once a week, the organic fertilizer solution mainly containing nitrogen fertilizer should be poured, not too thick. Fertilization should be based on the principle of sufficient amount, small amount and multiple times, so as to be economical and diligent. Because of the long harvest period of pitaya, organic fertilizer should be applied again, and nitrogen, phosphorus and potassium compound fertilizer should be applied in a balanced way for a long time. Completely using fertilizers with too high nitrogen content in pig manure and chicken manure makes the branches thick, dark green, fragile, easy to break in strong wind, large and heavy fruits, poor quality, low sweetness and even sour or salty.
blossom
Pitaya has a long flowering period, large flowers and high demand for nutrition. Therefore, in addition to strengthening the management of fertilizer and water at seedling stage, organic liquid fertilizer containing phosphorus and potassium fertilizer should also be topdressing 1 time before flowering, and topdressing 1 time every 5 to 7 days. Potted pitaya on balcony and roof is limited by the small amount of soil and nutrient supply, and the lateral branches should not be too long, and each branch should not exceed 3. Finally, we have to pick two flowers to eat, leaving only 1 flower. Pitaya can be self-pollinated, but cross-pollination has higher seed setting rate and delicious fruit, so artificial pollination should be carried out if possible. When the flowers bloom at night, use a new brush to get some pollen from the stamen anther of one flower and bounce it onto the pistil stigma of another flower.
Fruit stage
Pitaya ripens within a month from flowering to fruiting. After the pitaya bears fruit, the fruiting branches should be pruned in autumn, and the pruned branches can be cut. Fertilize as little as possible after pruning in autumn, and there will be more fatty new branches. Generally, 3-4 new shoots are left as fruiting branches every year.
Spend the winter
In most parts of the north, to keep out the cold, just move indoors. It's best to put it on a sunny windowsill. It should be noted that fertilization is not allowed in winter. Proper control of watering. Don't leave the room too early after spring. Generally speaking, you will definitely leave the room after mid-May. After leaving the room, the side branches that bear fruit in the first year are cut off from the near roots to promote the appearance of new side branches and lay the foundation for early flowering and fruiting in that year, otherwise the original side branches can no longer blossom and bear fruit.
Making potted pitaya at home may have the following problems.
How to plant potted pitaya?
I. Insufficient nutrition
Pitaya likes to eat fat meat, so it is recommended to choose fertile and loose soil when mixing soil. But after all, the nutrients in the soil are limited. With the continuous growth of plants, more and more nutrients will naturally be needed, and the nutrients in the basin soil will be less and less, which will easily lead to the phenomenon of poor growth or growth stagnation of plants because they can not get enough nutrients to meet their growth needs. So there will be slow growth or short height.
Second, the temperature reason
As we all know, pitaya is a tropical plant, so the temperature requirement is very strict. If its growth environment can't meet the needs of its own growth and development, it can't meet its growth, and naturally it will grow slowly or not. In the maintenance and management of potted pitaya, water and fertilizer management is very important, which not only affects the growth of plants, but also determines the flowering and fruiting. The principle of "watering thoroughly without watering" should be adopted for watering, and the principle of "applying thin fertilizer frequently" should be adopted for fertilization.
Third, scientific and reasonable pruning.
Pruning can not only make potted plants more beautiful, but also be a common means to promote plant growth. Potted pitaya should be pruned from the growing period. In order to make it grow more vigorously, it is necessary to erase the lateral buds and branches sprouting on the plant during the growth period, and only keep the terminal buds with growth advantages, so as to accelerate its germination and make the plant grow taller. When the plant grows to a suitable height, we need to top it and cut off the terminal buds, which will promote it to grow more lateral branches and make the plant more plump and beautiful.
Fourth, it is caused by rotten roots.
Root rot is a puzzling problem for most plants, even if it is not a devastating disaster, it will hurt vitality. Once the root rot of pitaya occurs, the plants can't get the nutrients and water needed for growth from the roots, which leads to poor growth and even death. Of course, there are many factors that lead to rotten roots, but it is mainly caused by excessive watering.
When can potted pitaya blossom?
Pitaya, native to tropical and subtropical areas of Central America, is a cactus plant that has settled in Chinese mainland in recent years. It can not only watch flowers, but also collect fruits. It can not only be cultivated in high yield on land or in greenhouse, but also potted on balcony and roof.
Pitaya can bloom continuously from April to June every year +0. 1.65438. Mature fruits weigh more than 500 grams, and the big ones can reach 1.500 grams. The skin is bright red with golden scales. There are two kinds of pulp, red and white. The fruit is sweet but not greasy, light and fragrant, better than cantaloupe, and has excellent taste.
Pitaya is very adaptable, regardless of soil quality. It can be planted in an environment where the temperature is below 8 for a short time, and can be put indoors for wintering in places with low winter temperature in the north. A small amount of pitaya can be cultivated by buying seedlings or asking friends for some pruned branches (10- 15 cm long), and can generally survive in plain sand. If well managed, it will bloom more than 70 days after planting.
