How to grow bell flowers to be beautiful
Note watering and lighting
Flowering plants grow well in cool conditions (about 50% light). Regularly water in the early morning, do not water in the afternoon because the plant will be susceptible to disease. Watering can be done in many ways such as misting, drip irrigation, etc., but must ensure enough moisture to cool the plants. When the flower has bloomed, only water the root, do not water the leaves and flowers, do not water too wet because the plant is easy to rot.
Fertilize properly
Plants under 1 month old need to be sprayed with micronutrients such as: Polyfeed (19-19-19); Growmore (30 – 10 – 10)… Plants over 1 month old, in addition to micronutrients, need to be sprayed with other growth stimulants such as: Atonik 1.8 DD, AgrostimTM USA… To form buds, it is necessary to add Muti – K (13 – 0 – 46) and calcium nitrate (11 – 0 – 0 – 20 CaO) for long lasting flowers.
If you want a tree to grow quickly, you must cut off leaves and prune buds
In order for flowers to bloom in focus, the first 2 buds need to be trimmed (when the buds have changed color). Prune away dead leaves and flowers to avoid disease. The dead flowers separate the flowers from the sepals. After all the flowers have died, it should be cut close to the base, so new shoots will grow from the tuber below the ground. Continue to fertilize and take care of the process, the tree will have new flowers.
