Because of the large amount of flowers and the large number of flowers, hibiscus flowers have higher requirements for fertilizer. The basin soil we use for cultivation can be mixed with garden soil, compost and river sand according to the ratio of 6:3:1, or it can be cultivated with the combination of phosphorus and nitrogen plus compound fertilizer plus floating sand or perlite.
Hibiscus flowers must keep enough light during the maintenance period. It is not easy to bloom in the hidden environment. It requires a large amount of water, and it is necessary to ensure sufficient water, so the growth of hibiscus flowers in the dry environment is affected. It opens a relatively large number of flowers, the number is also more, in the flowering and growth period to pay attention to timely topdressing, generally speaking, we can topdressing once every ten days or so a thin mature liquid fertilizer, pay attention to increase the content of phosphorus and potassium fertilizer, can meet the requirements of raw flowers.
The ground part of hibiscus flowers will wither in winter, and the underground part will winter in the form of roots. If it's for indoor maintenance, we suggest that it should be placed in a room temperature of more than 10 degrees, so that it can safely survive the winter. If it's a relatively cold environment of about 0 degrees, it's necessary to completely stop fertilization, control watering, cut off the dead part, and let it pass through the winter smoothly.
