How to water the potted peony flowers how to turn the peony leaves yellow

Watering and fertilization are very basic steps in plant breeding, which is to provide necessary water and nutrients for plant growth, so whether watering is correct or not will have a very direct impact on plant growth and development. may lead to plant leaves yellowing, or rotten roots and other phenomena, so to plant a plant, it is necessary to learn to water plants.

How to water potted peonies

Peony flowers for fleshy roots, watering should not be much, usually not watering in winter, other time watering there is no obvious time interval, according to the weather conditions and basin soil conditions timely watering.

After May, the weather gradually turns hot, if the weather is relatively dry, it can be properly watered, but the basin soil should be dry rather than wet.

In case of showers or continuous rainy weather, be careful not to accumulate water in the basin so as not to damage the plant. After the rainstorm, the soil should be loosened in time to improve the aeration condition of the soil.

What if the leaves of peony turn yellow when planted in pots?

1. Improper watering

Watering too often, too much, there will be the phenomenon of young leaves yellowing, old leaves have no obvious change. When the plants were not watered too much, the old leaves began to turn yellow from the bottom up. If the lack of water for a long time, the leaves of the whole plant were dark and yellow, and even died.

Solution: watering should be timely, appropriate amount, watering according to the situation of basin soil. Smaller flowerpots should be watered frequently, while larger flowerpots should be watered after the soil surface dries. It is appropriate to water thoroughly and do not accumulate water in the basin soil.

2. Improper fertilization

If the fertilization is too much or too often, the leaf surface grows well, the leaf quality is thick and glossy, but the leaf will be uneven for a long time, and the rotten root may appear in serious cases, while when the peony is insufficient in nutrients, or does not apply fertilizer for a long time, it is characterized by yellowing of young leaves and young stems, which gradually causes the whole plant to yellowing and even death.

Solution: fertilize too much, water in time, remove the plant from the pot when serious, and change the soil. When there is a lack of fertilizer, do not apply heavy fertilizer at once, replenish nutrients step by step.

3. Rotten root

Peony is a fleshy root, the pot soil is uncomfortable, did not change the basin in time, bacterial infection will cause rotten roots. In the early stage, it is difficult to find anomalies in the aboveground parts, but the absorptive capacity of the roots gradually weakens, and the lower leaves will gradually turn yellow and gradually spread to the whole plant.

Solution: change the basin every year to check the growth of the root, and trim the root in time. Be careful when watering to avoid stagnant water and rot the roots.

4. Diseases and insect pests

Peony flowers are often harmed by grubs, mole crickets and other underground pests and nematodes, the leaves are green and yellowish, and even scorched leaves. The main characteristic of this symptom is the yellowing and scorching of the leaves of a single plant or several plants in a certain place.

Solution: irrigation the root with medicine in time when there are symptoms, or remove the plant from the pot and replace the new soil after disinfection.

Pruning techniques of potted peony flowers

1. Early spring pruning

In early spring, the peony will wake up from dormancy and gradually transition to the growing period. at this time, check the buds on the branches and keep only 2 or 3 buds at the top to remove the rest. In addition, check whether the rhizome is sprouting and dig it out in time.

2. Prune the flowers after fade

After flowering, peony petals and withered leaves should be removed, which can reduce the consumption of nutrients in the basin and is beneficial to the division of flower buds. When the flower bud differentiation is more obvious, only the buds on both sides of the branches are retained, and all the buds at the top are cut off.

3. Pruning before winter

Winter plants just enter the dormant period, when pruning is the best time. All the overlapping branches, cross branches, disease and insect branches on the plant can be cut short for the thin branches, which can promote their rejuvenation. For overgrown branches, cutting short can reduce the consumption of nutrients.

Soil requirements for planting peony flowers

First, the quality of cultivated soil

If it is planted in the open air, plant it in an area with sunshine and no stagnant water. With common cultivated soil, it is also possible to use PH medium or slightly alkaline soil. It is suitable for more breathable fertile soil, the soil should be deep enough to be able to drain water.

2. Potted soil

If it is planted in a basin, it should be covered with pebbles at the bottom of the basin, which should be 3 to 5 centimeters thick to facilitate its discharge of excess water. The soil in the basin had better use loess to mix some cake fertilizer, or mix animal manure with ordinary garden soil and rough sand.

In addition to effectively watering and fertilizing it, planting peony may also face some problems in the growth process, such as yellowing of leaves, overgrowth, and so on, so we have to learn and master plant pruning and find out the causes of the problems, and so on. In short, it is not easy to raise a good plant.
