How to dwarf potted dahlias?

The cultivation techniques of potted dahlia include cutting with buds, changing pots and cutting roots to control water and picking hearts for many times at the right time.

1. Cutting with buds. Select the newly budding stem, cut it at 0.5 cm below the 12cm section, cut it into a horseear shape, first dip in the ash of the grass, remove the leaves at the bottom of the stem, cut it into the basin soil, place it in a cool place, and then move it to the sunny place when it begins to grow. In the process of management, watering should be combined with foliar spraying, and fertilizer and water management should be appropriate to avoid excessive water.

2. Change the basin and break the root to control the water. The seedling branches propagated by cutting method will be broken after 3 or 4 times of pot change, and then control the fertilizer and water squatting seedlings, which can control the exuberant vegetative growth and dwarf it.

3. Pick the heart at the right time. When the main stem of the potted plant grows to 6 cm high, it can begin to pick the heart, promote the lateral branches, and then pick the heart. At the same time, continuous smearing, spraying dwarf and plastic construction treatment can control the exuberant vegetative growth and achieve the purpose of dwarfing.

① cuttings with buds. Select the stem branches that just show buds, cut them at 0.5 cm below the 12 cm long section, cut them into horseshoe shape, first dip in a little rooting powder, then dip in a little plant ash, remove some large leaves on the stem, cut them in the potted soil, and place them in a cool place. It began to take root after 10 days and moved to the semi-shady place. When it begins to grow, it will be moved to the sun.

In the process of management, it is necessary to combine watering with foliar spraying, and the management of fertilizer and water should be appropriate to avoid excessive water and dwarf growth.

② changes the basin and breaks the root to control water. After 3 or 4 times of pot change, the seedlings propagated by cutting must break part of the roots. Coupled with the control of fertilizer and water for squatting seedlings, the bud growth of bandit Sheng can be controlled and dwarfed.

③ picked the heart at the right time. When the main stem of the potted plant grows to 6 cm high, it can begin to pick the core, promote lateral branches, and then pick the heart, plus continuous sprouting, spraying dwarf, shaping and pruning treatment, which can control the exuberant vegetative growth in order to achieve the purpose of dwarfing.

What should I do if I want to dwarf potted dahlias?

To dwarf dahlia plants and make their flowers plump, you can start with the following points:

① uses buds for cutting propagation, that is, branches grow about 12 cm, cut off with a sharp knife from 1 cm below the node, cut off the stem leaves, cut with plant ash or purple medicine solution and other antiseptic, cut with the sower prepared in the plain sand basin, pour water thoroughly, cover the plastic film on the shade, spray water twice a day, move to the semi-shade after about 10 days, take root after 20 days, and transplant the pot when the root grows to 4 cm long. It is not suitable to water too much in the early stage of potting, but Zhai often sprays water on the leaves and carries out normal management during the growing period of new seedlings. Potted dahlias with about 35 cm flowers can be cultivated in about 2 months.

② change basin to control water. Potted dahlias were selected as dwarf varieties and germinated indoors at the beginning of April. when the buds grew to 2 or 3 true leaves, plain sand was inserted under the base to promote roots, and when the roots grew to 4 cm, they were boiled. In the process of seedling growth, the pots were changed for 3 or 4 times from small pots to large pots, and some large roots could be properly cut off each time to inhibit plant growth. At the same time, controlled watering should be carried out to "squat seedlings" to prevent overgrowth. Usually less watering, hot summer weather should be sprayed to the leaves once or twice a day, in order to supplement the water lost due to rapid evaporation, do not pour water in the evening, in the morning can only water enough water needed during the day, in order to keep the tender leaves and shoots can stretch naturally.

③ picked the heart at the right time. When the seedling grows to 6 cm, 4 leaves are left on the main branch, 2 leaves are left on the side branch, and then the heart is removed properly according to the need, and the axillary buds are wiped off at any time.

④ was sprayed with chlorpheniramine. When the plant grows to a certain height, spraying appropriate amount of B9 at the right time can shorten the Internode and dwarf the plant.
