Cultivation methods and precautions of Ageratum

How to grow Ageratum

Pot soil selection

To grow ageratum, you need to choose suitable potting soil. Generally, when planting in pots, a ageratum seedling can be planted in a 4-inch pot. The soil should be a mixture of garden soil and fine sand, with some fertilizer added. After planting the ageratum seedlings in pots, you need to water the pots sufficiently and place them in a cool place to help the seedlings grow.

Light and temperature

Ageratum prefers a warm and sunny growing environment. It is not cold-resistant or heat-resistant. The suitable temperature for growth is between 12℃ and 25℃. There must be sufficient light, otherwise it will cause the plant to grow too tall. Ageratum is not cold-resistant and needs to be placed in a well-lit place indoors in winter, and the temperature over the winter should be kept above 5℃.

Water and fertilizer management

Ageratum needs good water and fertilizer management. Basically, the soil in the pot should be moist. Water it when the soil is dry. Water it more frequently when it is growing vigorously, and reduce watering in winter. Generally, a thin layer of fertilizer water is applied every 10-15 days. In order to achieve better flowering, some phosphorus fertilizer and potassium fertilizer need to be sprayed frequently.

Things to note when growing Ageratum

Pests and diseases

Ageratum is often harmed by pests and diseases. The main diseases are root rot and rust, which can be treated by spraying pesticides. There will also be attacks by pests such as fall moths, whiteflies, and aphids, which must be discovered and controlled in a timely manner.

prune

Generally, in order to make the plant compact, plump, and produce more flowers, it is necessary to pinch the top frequently to promote branching. After the ageratum blooms, you can promote the sprouting of new branches by pruning the branches. Be careful to prune the branches that are too dense.
