Plant Care in July
Temperatures are still high in July. Raised garden beds absorb most of the heat from the sun. Among the methods of physically cooling plants, the use of mulch is one of the most common methods to keep soil moisture, breathable and cool.
Most of the plants are ready for harvest, although in July, the spring growth of the plants is over. In July, it is still a strong period for the growth of many plants. Therefore, the garden maintenance work in July cannot be ignored.
Planting: Plant in July with proper space between plants. Plants need enough space between the individual plants to ensure completely healthy growth.
Watering: Hot weather can easily cause plants to lack water, so watering is very important. It is best to water in the morning and evening. Be careful not to do it at noon. Watering when the temperature is the highest can easily damage the roots of the plant. For more details, please refer to the article: When is the Best Time of Day to Water the Raised Garden Bed?
Pruning: If trees and flowers are planted, pruning should be done in July. In summer, the growth of branches and leaves slows down. Gardeners should prune according to the growth conditions of the plants so as to achieve the effect of ventilation, light transmission, and clear layers.
