I. Treatment method of Dendrobium after flowering 1, pruning after flowering
The flowering period of Dendrobium is1~ June. Prune after flowering. All failed flowers, non-flowering branches, old branches and diseased branches of Dendrobium can be cut off, which can promote the growth of Dendrobium and increase its ornamental value. After each pruning, you need to water and fertilize in time, wait in the shade for a week, and then carefully cultivate in the sun.
2. Turn over the pots and change the soil
After Dendrobium is pruned, it is necessary to turn over the pots and change the soil, and choose a suitable soil pot. When changing soil, all old roots and rotten roots need to be cut off. It can't choose ordinary soil, and needs to be mixed with coconut coat, charcoal, fern root and water moss in a ratio of 3: 3: 2: 2. This mixed substrate is suitable for cultivating Dendrobium.
3. Water and fertilizer
Many flower friends don't know what to do after Dendrobium blossoms. After pruning Dendrobium, turning over pots and changing soil, we need to pay attention to watering and fertilizing. Water and fertilization should not be excessive, otherwise it will affect growth. After Dendrobium blooms, wait for a week, and then water it when the substrate is dry. We can apply solid controlled release fertilizer every 10 ~ 15 days.
4. Growing environment
Dendrobium needs careful cultivation after flowering. It needs to be moved to a well-ventilated and sunny place for culture. The temperature needs to be controlled at 20 ~ 30℃ to promote the growth of Dendrobium. If Dendrobium is handled well, it will continue to bloom in autumn.
Second, the propagation method of Dendrobium 1
Dendrobium can be propagated by cutting, and can be propagated in spring and autumn. Don't breed in rainy days. First of all, you need to select strong branches, then put them in the shade and wait for the wound to dry naturally to prevent the wound from rotting during cutting and affecting growth. Then, the treated branches are cut into the soil to keep the soil surface sanitation and soil moisture, and can be cultivated normally after rooting and sprouting.
2. Method of dividing plants
Dendrobium can also be propagated by ramets. Every 2-3 years, many new buds will grow at the base of Dendrobium. These new shoots can be separated from the mother plant, and the wound can be coated with carbendazim to prevent bacterial infection. After the wound is dried, it can be planted in the soil to keep the soil moist. After a week, it can be cultivated normally.
Three, Dendrobium pest control 1, macular disease
Dendrobium is prone to macular disease. At the early stage of the disease, irregular yellowish color will appear on some leaves of Dendrobium. If you don't look carefully, it will be difficult to find, and then gradually spread into black mold, affecting the ornamental value of Dendrobium, and even leading to its death. It is necessary to water Dendrobium in time, increase the amount of fertilization, get more sunshine, and spray 75% chlorothalonil 1000 times powder for control.
2.snails
Snails are insects often encountered in daily life, which will do great harm to Dendrobium. Eating it on the back of Dendrobium leaves will affect the ornamental value and seriously lead to the death of Dendrobium. Salt is usually sprayed around Dendrobium potted plants to control Dendrobium. If Dendrobium is found to be damaged by snails, the snails can be removed manually and the leaves can be washed with clean water.
Conclusion: Through the above introduction, I believe everyone knows the treatment method of Dendrobium after flowering, as well as the propagation method and pest control of Dendrobium. I hope everyone can cultivate beautiful Dendrobium in their lives.
