The best time to repot dahlias, preparations and steps for repotting

The right time to repot dahlias

The time to repot dahlias can be chosen from March to April each year. At this time, the temperature gradually rises, the light is sufficient, and the dahlia has strong growth momentum. This is the best time to repot, which can increase the survival rate of dahlias. You can also choose to repot from September to November in autumn, which is also a period of rapid growth and can promote the rapid survival and growth of dahlias.

Preparations for repotting dahlias

Before repotting the dahlia, stop watering and keep the soil dry to reduce damage to the roots. Gently pat the surrounding areas of the pot to loosen the soil. Hold the pot with one hand and take the dahlia out of the pot with the other hand. Be careful not to damage the roots of the dahlia during the process.

Dahlia repotting methods and key points

1. Pruning

When repotting dahlias, the roots should be trimmed appropriately. Since the root system of dahlias is relatively dense, proper pruning is beneficial to their later growth. All rotten and dead roots must be cut off, and overly dense roots also need proper pruning.

2. Soil preparation and planting

When repotting dahlias, choose nutrient soil and put base fertilizer at the bottom of the pot. Fill part of the soil in first, then plant the dahlia in, fill the soil around it, water it thoroughly, and place it in a place with scattered light for maintenance.
