How to care for newly bought black heart chrysanthemum

How to care for newly bought black heart chrysanthemum

1. Lighting

Rudbeckia loves light, but for newly bought potted plants, it is best to place them in a well-ventilated place with diffused light for 2 days to adapt, and then increase the light to full sunlight after 2 days. If it is maintained in a semi-sun environment, blackheart chrysanthemum can grow normally, but poor light will affect the flowering of the plant.

2. Temperature

The most suitable temperature for the growth of blackheart chrysanthemum is 15-28℃. Potted plants should be moved indoors for the winter. If planted in the ground in winter, the soil should be cultivated and covered with hay to prevent the cold during the winter.

3. Watering

For potted black chrysanthemums, the soil should be kept moist during the growing period, but water should not accumulate. Normally, you can observe that the soil surface turns white, and when you hold the pot, you can feel that the soil has become noticeably lighter, so water it thoroughly until water flows out from the bottom of the pot.

4. Pruning

The newly purchased rudbeckias are often potted plants that have already bloomed. We have to wait until the flowers fade and then cut off the remaining flowers and the two pairs of leaves under the flowers. By the way, cut off the dead branches and leaves to encourage new branches to sprout and another batch of flowers to bloom.

5. Fertilization

Do not apply fertilizer to blackheart chrysanthemums during their flowering period. After the plants have bloomed and been pruned, apply phosphorus and potassium fertilizers once every half a month. If you buy seedlings, apply balanced nitrogen, phosphorus and potassium fertilizers during the growing period to promote growth. Before flowering, use phosphorus and potassium fertilizers to promote flowering.

6. Pests and diseases

Among the Asteraceae family, rudbeckia is considered to be a plant with relatively few diseases and pests. In daily care, just avoid waterlogging and prevent root rot. Once root rot is found, the soil can be irrigated and disinfected with a solution of carbendazim.
