1. What about rotten roots

1. It's muggy in summer. Hurry to check whether the root is black and rotten. The root is under the soil and sometimes can't be found. When you see air roots growing on the stem, or the stem is black and soft, nine times out of ten it is rotten

2. First, cut off the rotten part with a sharp knife. Apply carbendazim to the incision and leave it in a cool and ventilated place for 4 hours

3. For water insertion, prepare a bottle, pour in purified water, immerse the cuttings in water, and do not touch the bottom at the root, otherwise it will be unfavorable to rooting. There is no need to change the water halfway. The slowest time is 10 days

2. How to change one basin into many

1. First, cut off several strong and disease-free long-lived flower branches. Coat the cutting surface with rooting powder and dry it

2. Prepare transparent seedling box. You can use the plastic box of egg belt bought in the supermarket, one by one, which is very convenient to use. The medium is mixed with vermiculite and coarse sand, poke holes with chopsticks, bury cuttings and compact the soil

3. Water every night to keep the soil moist. It will take about 8 days to take root

4. After rooting, it can be transplanted. The flowerpot is first padded with half of the mixed soil of garden soil and vermiculite. If not, use the exposed garden soil. Put the long-lived soil mass after rooting into the middle and fill it around

3. How to grow into a big flower ball

1. If longevity flower wants to bloom into a big flower ball, it must first learn to top and pick the heart. The above figure is an example. An independent longevity flower is not good-looking. After picking the heart, side branches will grow from the side to make the plant shape more beautiful

2. The figure above identifies the number, representing 4 lateral branches. If you pick the heart twice, you can develop four lateral branches, which look more symmetrical, and the plant type is round and good-looking after flowering

3. The secret of topping is to pick branches wherever you want to be plump

4. How to water and grow fast

1. Not rotten roots is the basis for growing fast. Do not water too often. Prepare a small piece of bamboo near the basin on weekdays, insert it and pull it out. If the surface is dry without soil, you can water it

2. You can sprinkle a layer of bone meal on the surface of the basin soil, and it will infiltrate along the water when watering, which can supplement nutrition for longevity flowers

3. Watering liquid nitrogen fertilizer once a month can make the longevity flower grow strong branches and more flower buds. You can also buy some leaf fertilizer and spray it on the leaves, which can make the leaves grow big and shiny

5. How can we blossom early

1. Longevity is a short day plant, which explains why it usually blooms in winter. If you want to blossom in advance, you should simulate the winter environment, that is, shorten the sunshine time

2. The sun exposure time is controlled from 9 a.m. to 6 p.m. every day, a total of about 8 ~ 9 hours, and shading treatment at other times. You can find a large paper case or a large black plastic bag. If possible, it is best to use sunscreen net, which has good shading and ventilation

3. In such a month, you can conceive buds. When shading, don't have too much water. When you see that the basin soil is dry, pour it again. Otherwise, the air is not circulating and black rot is easy to occur

3. In such a month, you can conceive buds. When shading, don't have too much water. When you see that the basin soil is dry, pour it again. Otherwise, the air is not circulating and black rot is easy to occur

4. It is best to conduct flower induction treatment when the temperature drops below 28 ℃. Only large seedlings can be used for shading and flower induction to ensure that there are 5 pairs of leaves, otherwise there is little nutritional savings and can't afford to toss
