Diseases and pests of peony young shoots twist and die, leaves turn yellow, leaves do not stretch .

See if there is a picture in this?

When potting, the bottom of the pot can be spread with coarse sand or small stones 3-5 cm thick to facilitate drainage. The potting soil should be mixed with yellow sand soil and cake fertilizer, or with fully decomposed manure, garden soil, and coarse sand at 1:1:

1 ratio of mixed culture soil. The soil should be filled so that the root system is stretched and cannot be curled; After covering the soil, it should be compacted by hand so that the root system is in close contact with the soil, so that it is easy to survive. After potting, water once and put the seedlings in the semi-shade.

After being transferred to normal management, it can be placed in a sunny place to ensure that it has sufficient sunlight exposure. During the growth period, the soil should be loosened frequently, and compound fertilizer should be applied every half a month or so. Newly potted peonies can not be fertilized, especially avoid thick fertilizer, otherwise the fleshy roots will be moldy and rotten to death.

After half a year, you can gradually apply some thin fertilizer, such as rotten chicken manure or bean water, etc., and the ratio of fertilizer to water is 20%-30%. Newly potted peonies may not produce good flowers in the first year, but after 1-2 years of cultivation, they can bloom year after year. Peony blooms in mid to late April a year, and liquid fertilizer can be applied 1-2 times before flowering; Half a month after flowering, apply liquid fertilizer 1-2 times; Futian can use sesame paste residue (about 40-50 grams per pot) to apply dry fertilizer once to facilitate flower bud differentiation.

Peony is a fleshy root, slightly drought tolerant, most afraid of stagnant water, so whether the watering is proper is a key issue in the success or failure of potted peonies. Generally, the peony that comes out of the room in early spring should be fertilized once, and then watered thoroughly, and the soil should be loosened after the water is slightly dried. In the future, watering should be carried out in a timely and appropriate amount according to the weather and potting soil conditions, and the potting soil should be kept moist frequently, which is conducive to the growth and flowering of peonies.

Reasonable watering should be dry and wet, not suitable for large watering, to prevent water accumulation in the pot, so as not to rot roots and leaves.

When the peony blooms, it can be covered by a shed or temporarily placed indoors, avoiding direct sunlight, which can prolong the flowering period, and the top bud of the main branch is a leaf bud, which should be removed, so as not to grow and affect flowering. In order to make the peony bloom brightly, the dihydrogen phosphate solution available during the flowering period is sprayed 2-3 times. After the peony flowers are gone, it is necessary to carry out a plastic pruning, cut off the residual flowers and flower stalks in time, do not let the seeds set, and retain the 1-2 outer buds of the stem, so that the plant can grow vigorously and ensure that the next year blooms.

The reason for the yellowing of peony leaves is not one aspect, under normal circumstances, the wet and waterlogged young leaves are yellow first, the old leaves of the ground are yellow first, the yellow leaf veins of the ground alkali leaves are green and then yellow, and the lack of fertilizer and hypertrophy also have the situation of yellowing, you can refer to these situations.

1. If the potting soil is too wet for a long time, it will cause the root system to breathe poorly and the leaves will shrink and wither. The coping method is to loosen the soil in time, strengthen ventilation, control watering, and then watering will be dry and wet, which is expected to prevent water accumulation in potting soil.

2. Although the arid yellow-leaved peony likes to be dry, but too much drought will also cause the leaves to shrink and wither, and the response is to water and replenish water in time when the peony pot soil is too dry.

3. Peony cannot grow in too alkaline soil, so when mixing soil, use bran ash instead of plant ash, because plant ash is too alkaline. If the potting soil is too alkaline, the peony flowers will grow poorly, and the leaves will shrink and wilt, and acidic fertilizer should be applied in time to neutralize the alkalinity of the soil.

The soil is alkaline. Saline-alkali soil reduces the uptake of water and nutrients by the roots of peony, resulting in nutrient disorders. The high temperature and sunburn in summer aggravate the imbalance between the supply and demand of water and nutrients for plants, and the leaves are more prone to dry tips and dry edges, and in severe cases, the whole leaves wilt and dry out.

How to remedy the withering of peony flower leaves.

If you want to solve the problem of dry branches of peony, you need to prune dead branches, trim the potting soil, control watering, and control light. First of all, it is necessary to prune off the useless branches of the peony that have dried up, promote the germination of new shoots, trim the potting soil, eliminate the phenomenon of compaction, strictly control the watering, and prefer dry to wet, so that the plants can receive sufficient scattered light.

1. Prune dead branches

When we find that the branches of the peony are dry, we should use sterilized sharp scissors or tools to trim the dried branches in time. These branches are no longer recoverable, and continuing to attach to the plant will only waste nutrients, so removing them as soon as possible will preserve the nutrients stored by the plant.

2. Trim the potting soil

If the peony is dry, it is likely that there is a problem with the potting soil, and after we have cut the dead branches, we must start to tidy up the potting soil. We must first loosen the potting soil, if we find that the phenomenon of compaction or large soil clods should be crushed in time, pick out the weeds and other materials inside, and turn the soil back to the pot after drying and disinfecting.

3. Control watering

Peony is a plant that does not have high requirements for water, but it is easy to rot due to stagnant water and then dry up the plant, so when we water the peony, we must ensure that the soil is in a slightly dry state, and apply a little water appropriately, and it must not be too wet.

4. Control lighting

Peonies prefer a sunny environment, in which peonies tend to grow healthy and strong, but if we put peonies in a strong direct light environment for a long time, it will cause peonies to wilt. When the sun is too hot, we should move the peony to a place where there is enough scattered light.
