water

Dendrocalamus latiflorus needs a lot of watering during its growth to keep the basin soil completely wet. But don't let the plants soak in water, otherwise the leaves will turn yellow, wither and even the roots will rot and die. As long as the soil in the basin is not dry enough in winter.

Step 4 apply fertilizer

Fertilize Dendrocalamus latiflorus once a week during its growth.

Step 5 cultivate and change pots

Longtu bamboo should be planted in porous and well-drained culture soil, and humus, such as humus and compost, should be mixed in the soil. Or use peat soil and perlite to make the soil breathable and permeable. Planting flowers in smaller flowerpots will bloom well. You can turn over the pots in April every year and use fresh pot soil.

6. Reproduction

Cutting is the main way to grow Longtu bamboo at home. In spring or autumn, select healthy top branch 8- 10 cm, insert it in a flowerpot, cover the flowerpot with plastic film, keep moist and warm, and take root after 3 weeks.

Matters needing attention in Longtu bamboo culture

1, Dendrocalamus latiflorus is a flowering plant with a long flowering period. Potting of Dendrocalamus latiflorus should use fertile and slightly acidic sandy loam with good drainage. Generally, the pot should be changed once every 1-2 years, and it can be changed in early spring or after the flowers wither. When changing pots, first pad the drainage holes with broken tiles, then put a small amount of bone meal as base fertilizer, then put in 4 parts of new soil, 4 parts of garden soil and 2 parts of sandy soil, plant plants, and leave 2-3 cm along the mouth for fertilization and watering. After changing the pots, water them, put them in the shade to slow down the seedlings, and then move them to the sunny place for maintenance.

2. Long Tuzhu should not be fertilized too much. Every 7- 10 days at flowering stage, apply 1 times of decomposed pancake fertilizer and fertilize for 3-4 times. If Dendrocalamus latiflorus turns yellow during cultivation, topdressing and 0.2% ferrous sulfate water can be used to make the leaves turn from yellow to green gradually. Fertilize every half month 1 time. Add 1-2 times phosphorus and potassium fertilizer at the flowering stage of Longtu bamboo, or use "Huiyou" potassium nitrate for 20-8-20 seasons. Reduce watering and stop fertilizing in winter.

3. Pots of 12- 15 cm are commonly used for potted Dragon Tuzhu, and 3 plants can be planted in each pot. Adequate water is needed in the growing season. If the soil humidity is too high, the leaves will turn yellow and fall off. If the branches are not withered, stop watering and let them recover and grow new leaves.

4. In order to shape the beautiful plant shape of Dendrocalamus latiflorus, when the cuttings or seedlings grow to 15cm after potted, the branches are cut off from the pot mouth 10cm to promote the germination of stout new branches. During the growth period, the height of branches should be strictly controlled, and topping and coring should be paid attention to, so that the branches will be neat and densely flowered in the future. Half a month after coring, apply Bijiu or Chlormequat chloride to control plant height, so as to achieve short plants, luxuriant leaves and many flowers.

5, plastic pruning: household dragon spit beads generally grow very short, but in fact, its branches can grow very long, pay attention to plastic pruning, you can cultivate very beautiful dragon spit beads. It can not only grow branches, but also be pruned into beautiful dwarfs.
