Cultivation methods and precautions of Vinca rosea

1. Temperature

It likes a warm environment, and the temperature is best maintained at 20 to 33 degrees. In summer, the temperature should not be too high, and in winter, it should not be too low, and it should not be lower than 10 degrees. Below 10 degrees, it may cause it to not grow or enter a dormant state.

2. Lighting

It likes light and can tolerate partial shade. When growing it, be careful not to expose it to direct sunlight at noon in summer. It can be exposed to sunlight in the morning or evening. In winter, it should be given direct light throughout the day.

3. Watering

Catharanthus roseus likes high air humidity, but avoids waterlogging in the soil. When growing it, spray water more often to keep the soil in the pot dry and moist. Water thoroughly every 2-3 days in summer and every 5-7 days in winter, and spray water 1-2 times a day.

4. Soil

It can be grown in any soil, but it is best to use soil that is breathable, water-retaining and fertilizer-retaining. Mix leaf mold, garden soil, river sand and perlite in a ratio of 5:1:1:1.

5. Fertilization

It has a high demand for potassium fertilizer and a moderate demand for nitrogen fertilizer because of its abundant flowering. When fertilizing, you can use homemade organic fertilizer or buy common fertilizers for growing flowers. The time is once every 15-20 days, and the principle is to apply thin fertilizers frequently.

6. Notes

It is a relatively easy flower to cultivate. However, please note that the temperature should not be lower than 10 degrees. It will be frozen if it is lower than 5 degrees. It mainly depends on light and water. It likes high humidity so you need to spray more water, but the soil should not be wet so you need to water less, especially in summer and winter. Keep it wet when dry and water it thoroughly when watering. Dry means that the soil 2-3 centimeters above the surface is dry. Also note that it must not be exposed to direct sunlight at noon in summer.

If the humidity is too high, it can cause leaf diseases and pests like black spot and neck disease. Therefore, it is necessary to keep the watering and soil surface dry and not too wet. If pests and diseases occur, you can spray with carbendazim or thiophanate-methyl.
