How to Cultivate Violets

Regarding the knowledge of how to cultivate violets and the methods and precautions for violet care in the field of green plants and flowers, the editor will provide you with detailed answers below.

Violets are common ornamental flowers. When they bloom, they emit a strong fragrance and have bright colors, making them highly ornamental and widely loved by flower enthusiasts. However, many enthusiasts often encounter various problems while cultivating them. In fact, violets are easy to grow with proper care. The following will introduce their cultivation methods and precautions in detail.

I. Cultivation Methods

1. Proper Fertilization

It is well known that fertilizer is essential for plant growth, and this applies to violets as well. Violets enjoy fertilizer, and during cultivation, special attention should be paid to fertilization. Adding fertilizer can make the violet flowers more abundant. Applying a dilute phosphorus fertilizer once a month is sufficient. However, the concentration of the fertilizer should not be too high, as it can easily hinder the growth of the violet.

2. Watering Requirements

Violets enjoy moisture, so during their growth period, they should be given ample water. Water them once a week, making sure to water thoroughly and keep the soil moist. However, be careful not to add too much water; managing the water amount is crucial to prevent root rot in the violet.

3. Suitable Temperature

Violets enjoy warmth, with the most suitable growth temperature being 18-25°C. Therefore, in the summer when outdoor temperatures are high, violets should be moved to a cool place, or they are highly likely to develop yellow leaves. In the winter when temperatures are lower, the temperature around the violet should be controlled to about 11°C to prevent frost damage and affect growth.

4. Sufficient Light

Violets enjoy light and require at least 8 hours of sunlight per day to ensure adequate light supply. Insufficient light can result in fewer or smaller flowers. However, due to strong sunlight in the summer, appropriate shading is required, usually with a 45% shade level. Note that in the winter, they should be moved to a lit environment.

II. Precautions

1. Proper Pruning

During the growth period of violets, apart from paying attention to nutrients, water, and temperature, proper pruning should be carried out.剪掉弱 and diseased branches of the violet and clean up any rotten flowers; otherwise, a series of disease problems may arise, affecting the healthy growth of the violet.

2. Timely Pest Control

Many enthusiasts neglect pest and disease issues during the growth of violets, leading to unhealthy growth. The main pest affecting violets is the scale insect. If detected, it should be promptly removed; it can be cleaned with tools or directly sprayed with pesticides. Remember, once pests or diseases are detected, immediate control is necessary.
