What to do if Cosmos grows too tall

What does it look like when Cosmos grows leggy?

Cosmos is prone to excessive growth during maintenance, especially in the seedling stage. After the growth occurs, its branches and leaves will grow very fast and become slender. If it is serious, it will lead to a small amount of flowering or no flowering, which is extremely detrimental to the growth of the plant.

Causes of Cosmos's Lean Growth

1. If Cosmos grows too tall, it is first because there is not enough sunlight. The plant cannot carry out photosynthesis, causing it to grow too fast and thus grow too tall.

2. During the maintenance period of cosmos, if the fertilizer and water management is not done properly, excessive watering is performed, and a large amount of fertilizer is applied during the growth period, especially nitrogen fertilizer, which leads to excess nutrition, it will cause excessive growth.

How to deal with the excessive growth of cosmos

1. After the cosmos starts to grow too tall, it needs more light and should be moved to a place with sufficient sunlight for maintenance. Under the effect of light, it will gradually resume its growth and the plant will become stronger and stronger.

2. After the cosmos starts to grow too tall, you need to control watering and it is best to stop fertilizing first, so that it can gradually recover. It is best to apply some potassium dihydrogen phosphate when fertilizing.

3. When Cosmos is growing, it needs to maintain a good ventilation environment. If the excessive growth is serious, it is necessary to pinch and top the plants.
