Due to the limitation of specific environmental conditions, the daily maintenance and management of potted flowers is much more complicated than that of terrestrial flowers, and it is also the key to success or failure. Daily maintenance management should pay attention to the following points:

First, water. Potted flowers can only survive by artificial watering. When watering, we should first understand the water demand habits of flowers, and also comprehensively consider the sunny weather, temperature and humidity, plant size, pot soil, flower pot size and other factors.

1, watering amount. The watering amount of potted flowers must be treated differently according to different types and different growth and development stages, and different watering amounts should be mastered in different seasons. Generally, the consistent wetting from the pot surface to the bottom of the pot is the degree. Avoid watering the waist (wet on the top and dry on the bottom) and water in the pit (water accumulated at the bottom of the pot), and avoid the loss of soil and fertilizer from the hole of the pot, which will cause the center of the pot to sag and seriously affect the growth and development of potted flowers. In spring and autumn, in addition to normal watering, water should also be sprayed on leaves and the ground frequently to increase environmental humidity and prevent young leaves from dying and flowers from dying prematurely. When new seedlings are put into pots and big seedlings are put into pots, because the roots are damaged to varying degrees, it is advisable to plant them with moist soil (once squeezed into a ball, they will be scattered when rubbed). According to the climatic conditions, irrigation is not allowed for 4-48 hours, which can accelerate the healing of root wounds, promote plant rejuvenation, prevent rotten roots, yellowing leaves and plant rejuvenation, and prevent rotten roots, yellowing leaves and plant atrophy and deformation. When the pot soil is too dry due to drought or leakage, and the tender leaves droop and shrink, put the flowerpot in the shade, water it a little, and spray a little water until the leaves stand up. If there is too much continuous watering or the soil is too wet in rainy days, the whole potted flower can be taken out and placed in a cool, ventilated and rainproof place, and a small amount of water can be sprayed on the leaves. After 3-5 days, the plants will be restored to the pots for maintenance.

2, watering time. The watering time varies with the season. Before spring, summer and autumn 10 am, after 2 pm in winter. The water temperature is close to the soil temperature, slightly higher in winter and slightly lower in summer.

Second, fertilization.

1, base fertilizer. Potted flowers are often applied with base fertilizer, which is mainly organic fertilizer with appropriate compound fertilizer. Organic fertilizers are mostly mixed with soil, such as livestock manure, cake fertilizer, bone meal, etc.

2. Top dressing. Potted flowers should be topdressing according to different growth stages during the growth period, and topdressing should be based on the principle of light fertilizer and diligent application. Commonly used as topdressing are: cake fertilizer, decomposed cow dung, residue after oil pressing, hoof pieces and horns, alum fertilizer and water. Topdressing should be targeted. For example, for foliage flowers, oil residue cake fertilizer with more N content should be used at seedling stage, and P and K fertilizers should be used for flower bud differentiation and bud stage, such as decomposed chicken manure.

Third, plastic trimming. Plastic pruning usually includes the following measures: pruning, coring, bud stripping, bud removal, flower thinning, fruit thinning and so on. Pruning is mainly to cut off branches of pests and diseases, overlap branches and adjust plant shape. The purpose of core removal is to enrich branches, regulate growth, increase lateral buds, and make plants plump and flowers in full bloom. The main purpose of stripping and removing buds is to preserve nutrition and concentrate nutrition on pregnant buds. Flower thinning and fruit thinning are mainly aimed at fruit-viewing flowers. After flowering, the flowers that are not ready to bear fruit should be picked as soon as possible, and some residual flowers can be cut off before the flowers wither. If there are too many fruits, you can also thin some fruits.

Fourth, turn over pots and change pots.

1, change the pot. There are two situations: first, because the roots have filled the soil in the pot, and even some roots have drilled drainage holes, it is necessary to change a larger flowerpot; Secondly, because of the long time of potting soil and the lack of nutrients in the pot, it is necessary to replace the culture soil. The size of the pot is variable, and changing the pot is mostly carried out before and after leaving the house in spring.

2. Turn the washbasin over. After the original pot soil was poured out, the old roots of the plants were cut off by 1/3, leaving only the protective soil and most of the roots. At the same time, properly prune the branches and leaves, then put them back into the original pot and put on new culture soil.

Five, in and out of the room time. Generally, greenhouse flowers in the northern region will leave the house one after another at the end of April and the beginning of May. Before leaving the house, the ventilation frequency and time should be gradually increased, so that greenhouse flowers can gradually adapt to the external environmental conditions. Flowers generally enter the room from the end of September to the beginning of 10, and should be moved in or out in stages according to the temperature requirements of flowers.
