What should be noted when growing flowers at home in spring?

1. Repotting

Generally, flowers and green plants are bought in pots, and after bringing them home it is best to keep them in the original pot and not repot them hastily, especially at this time, when the weather is warm at first and then cold again; many plants have deeper roots, and once repotted, the roots of the flowers will not absorb nutrients well, causing the plants to die. When buying, also pay attention to whether the potted flowers have already been repotted when they are sold. Generally, soil that has not been repotted is rather hard and clumpy, while the soil of flowers that have already been repotted is looser. Of course, some flowers have already been grown for many years, and you can choose to repot them once from March to April, because the climate conditions in these two months are favorable for the survival and growth of the flowers.

2. Watering

For fruit-viewing plants such as Buddha's hand and kumquat, not only should the potting soil be kept moist, but water must also be sprayed on the leaves, flower buds, and fruits, so that the leaves can be emerald green, the flower buds can swell rapidly, and the fruits can be brightly colored. For purchased cymbidium orchids, poinsettias, and others cultivated in greenhouse sheds, because the temperature and humidity in their original environment differ greatly from those in the home, if the leaf surfaces are not frequently sprayed with water, the leaves will often become shrunken and dry. For various bromeliad flowers such as Guzmania and Guzmania 'High Red', if the room temperature is below 10 to 15°C, not only should watering be controlled, but too much water should also not be poured into the leaf cups, to prevent heart rot.

3. Fertilizing

For camellias, sasanqua camellias, azaleas, clivias, red plum, cymbidium orchids, and others, as long as the room temperature is not below 15°C, a compound fertilizer can be applied once every about 15 to 20 days; for tree-stump bonsai and potted foliage plants that have entered dormancy, all forms of topdressing should be stopped.

4. Pruning

From March to April, for potted ornamental plants, the dead branches, yellow leaves, and branches and leaves infected with pests and diseases should be cut off together and destroyed. Some varieties such as rubber tree and happiness tree need "pinching," that is, cutting off the highest growing tender tip, with the cut length being 2 to 3 cm; after cutting, pot-bottom ash can be used to seal the cut surface for disinfection.

5. Cold protection

Because it is still a season of warm at first and then cold again, the potted plants placed on the balcony should be determined according to the lower limit temperature that different ornamental plant species can tolerate. Before a cold wave arrives, they must be moved indoors to avoid the cold, or a double-layer plastic shed can be built directly above the plants for cold protection.

6. Pest and disease control

For scale insects, whiteflies, and others appearing on potted plants, they should be wiped off promptly with a damp cloth; for aphids appearing on potted plants, water soaked with tobacco powder (or tobacco shreds) can be used to kill them.

Flowers can make people feel happy, and beautiful flowers are even more pleasing to the eye. Take good care of those flowers.
