Why are the leaves of Cymbidium orchids curling? How to prevent and treat the curling of Cymbidium orchid leaves?

As people's quality of life improves, more and more people like to grow some flowers and plants at home, and cymbidium is one of the common flowers. So what is the reason for the curling of cymbidium leaves? How to prevent and treat the curling of cymbidium leaves? Let's take a look.

Why are the leaves of Cymbidium orchids curling?

The main cause of leaf curling is malnutrition caused by improper watering and lack of fertilizer! The leaves are loose and lack nutrients. If the leaves are curled due to nutritional imbalance, you can use potassium dihydrogen phosphate mixed with water to spray the leaves. Or fertilize them with trace element water-soluble fertilizer.

How to prevent leaf curl

1. Improper watering

First of all, orchids like to grow in moist but not wet places with good air permeability, and they also need good ventilation. The planting material of cymbidium orchids should be as coarse as possible. It should be able to flow out directly from the bottom when watered. Water thoroughly when it is completely dry.

2. Nutrition

Orchids need a lot of fertilizer. Livestock manure, rice washing water, egg shells, leftover rapeseed cakes, and unfinished milk are all good fertilizers. But they must be "decomposed" before use. Otherwise, after fertilization, the fertilizer will ferment in the pot, causing root burn and leading to the death of the entire plant.

Orchids do not like heavy fertilizers. No matter what kind of fertilizer you use, it should not be too concentrated. Apply thin fertilizers frequently. Raising orchids is difficult and easy. Just observe more and pay more attention.

How to grow cymbidium orchids

1. Matrix

Remember, all orchids are not grown in soil, and cymbidium orchids are no exception. They all have fleshy roots and need sphagnum moss or wood blocks as a substrate. You can use sphagnum moss or wood blocks alone, or a mixture of the two.

2. Sunshine

It likes sunshine and can tolerate partial shade. Compared with Phalaenopsis, Cymbidium orchid prefers sufficient sunshine. If there is insufficient sunshine, the leaves will become very long and the flowers will not bloom well.

3. Watering

This mainly depends on what substrate is used. If it is sphagnum moss, the moisture retention is relatively good, and water it once every 5 days. If it is wood blocks, the moisture retention is poor, and water it once every 3 days. Because its leaves are hardy, water evaporates slowly, and the root system is fleshy, if watered too frequently, it will cause root rot.

4. Fertilization

Cymbidium usually blooms around the Spring Festival. If you fertilize it enough, it will have more flowers and they will be relatively larger. When you have time, you can dilute the liquid fertilizer with water and water the flowers and spray the leaves. During the flowering period, phosphorus and potassium fertilizers are mainly used. Potassium dihydrogen phosphate and bone meal have higher phosphorus and potassium fertilizers.

5. Temperature

The suitable temperature for its growth is 10-25℃. It is afraid of cold in winter and heat in summer. In the north, it should be moved indoors in winter and properly shaded in summer.
