How to take care of dahlia flowers

1. Dahlia needs a cool climate , a preferred temperature of 15-30 degrees C. It needs high humidity but cannot tolerate waterlogging.
2. This flower species needs to be well lit but by the time of flowering it is necessary to have less light and cold conditions to differentiate the flower buds.
3. Dahlia flowers early, only about 50 - 60 days for flowers.Therefore, anyone who intends to plant dahlia must calculate to be able to collect flowers right on Tet.
4. Care before flowering : disconnect all buds on the young branch from the letter of the letter upward.Place the pot in a sunny position, then water it after the soil surface in the pot is dry.
5. After flowering : proceed to pruning, keep only 2-3 branches to help develop axillary buds and can enjoy flowers again in the fall.During blooming flowers, fertilize once a month.
6. This flower needs to be well lit but by the time of flowering it needs less light and cold conditions to differentiate the flower buds, so it should be kept in a place that is free from frost.

About 4 - 5 months when the medicinal plants do not allow the flowers to die, cut off the stem.

Dahlia can be propagated by seeds, by tubers or by cuttings. The branches of the dahlia are cuttings, if there are stimulants, only 5 - 7 days will be rooted.

Propagation by seeds, only applied to single flower size, dual flower varieties propagated by sprouting buds or bud buds, axillary buds. About 4 - 5 months when the medicinal plants do not allow the flowers to die, cut off the body, leaving 20 - 30cm, beat the whole tree, put it in a cool place or put the soil into bundles, put in the house.

At the beginning of August, the roots were planted, remembering that if the stem fragments were lost, self-cultivation could not produce well-grown shoots, after 15 - 20 days from the stems, sprouting sprout. Once every 12-15 days, take the scion once and bring the cuttings. If the soil is in a high place, leave the whole tree intact, summer need eao trees to cover it.

In July - August, the buds were sprouted, and many shoots were removed with 4 - 6 leaves. If the whole stem was removed, the roots of the new tree were quickly rooted. Can also cut the tree.

Digging roots: the appropriate time is mid-November. After digging up the roots, do not remove the soil, so store in a place that is not soaked with dew.

In the old days, people had to split the sprouting foot into 2 - 4 so that the vinegar gave much root.

After 2 tops of tops from an original mother tree, 9 to 15 tops can be cut and cutted.

- Preparing mother tree garden : if needing to grow from 15-20 ha of dahlia flower, there should be 1 ha of mother seed garden to ensure quality and pestilent. In addition to the standards of flower production gardens, the arrangement of the force to select the mother plant must ensure the technical requirements such as tall, airtight, close to the road to facilitate the transportation and preservation of preschool and if there are things It is recommended to build a house covered with nylon to avoid heavy rain, high winds, hot sun .

The selected seedlings were imported, from tissue culture or from sprouts in the garden that produced a strong, healthy, pest-free root grown at a distance of 15 x 15cm (density of 400,000 trees / ha). After planting from 12 to 15 days, start the first time to plant the branches for many branches and 20 times after the first time to press the tops.

After 2 tops of tops from an original mother tree, 9 to 15 tops can be cut and cutted. This tops also has the effect of creating canopies and sprouting plants. After that, every 1 to 20 days will be collected. Thus, from 1 tree can be up to 50 - 70 sprouts.

With such a high level of cutting and sprouting in one crop from 4 to 6 months, 1 ha of mother trees can provide from 6 to 8 million buds to grow from 15-20 ha.

Choose cuttings, not too old, not too young.

- Prepare the cuttings house : If conditions permit, use fixed houses with greenhouses, greenhouses with devices to regulate light, wind, temperature and humidity. In addition, people can design simple houses with cheap materials such as curved bamboo sticks with arc shape with the arch from n2.2 to 2.5m, 1.8 - 2m high. covered with 2 layers of nylon to limit the light intensity and reduce the temperature, limiting rain and wind and keeping moisture inside.

Choose the cuttings, not too old, not too young, have a healthy life with a length of 6 - 8cm, from 3 to 4 green leaves, no pests to bring cuttings. Big branches, leaves are too thin (3 x 3cm = 1,000 branches / m2); small branches, less thick leaves (2.5 x 2.5cm = 1,500 branches / m2); autumn is thicker than summer.

- Handling cuttings : Cut cuttings in the morning, handle and soak immediately to avoid dehydration, wilting plants will affect roots. Use growth stimulants such as IAA, IBA or NAA to dilute the concentration from 25 to 50ppm, immerse the branch root in the solution for 10-15 seconds to stimulate plants to root.

- Cuttings : Plug stem branches 1.5 - 2cm deep on the beds or in specialized plastic trays containing clean soil. Can be caked in two ways: dry cuttings (plug stems into clean sand and water) or wet cushions (water soaked wet sand and cuttings). The time for root cuttings is about 10 - 15 days depending on the weather (hot season and cold season takes 15 - 20 days, cool months take only 7-10 days) so need to base on planting season production for appropriate cuttings layout.

Regularly water enough water by spraying mist for fast cuttings roots (the first days of spraying 3-4 times / day, the days after spraying gradually reduce but still ensure green leaves). Cut yellow leaves, old leaves, spray additional foliar fertilizer when the branches have recovered and rooting for good growth. After 12 - 15 days after cuttings, each tree gives 3-5 roots 2 - 3cm long, the leaves are stable and can be planted to produce garden.

Technical care for dahlia flowers

When preparing to bud, pay attention to put the tree in the dark, where the temperature is low to make the plants flowering.

After 7-8 days the seeds will germinate. After 20 - 25 days, seedlings will be transferred to new pots to take care. Dahlia is a light-loving species so leave the plants outdoors. But when preparing to bud, pay attention to put the tree in the dark, where the temperature is low to make the plants flowering. At the same time watering every morning and evening to create moisture for the soil, avoiding the situation of sunburned trees.

Fertilizer for dahlia is mainly manure and compost. In the process of making the bud, pay attention to adding nutrients to the plants for beautiful flowers.

Pest and disease control: Dahlia flowers are often eaten by leaf worms, leaf rollers and fungi. Leaf spot disease will arise mainly in the rainy season due to humid weather, yellow head spots on the leaves appear, then spread into round brown spots. In this case you should use Zineb 0.1% water and Boocdo 0.5% to spray.

If the plant has root rot, the main reason is because water is irrigated so much that the soil is too moist. The only way to deal with this situation is to clean the 60 degree alcohol, then replant it.
