The plants with mud balls were then planted in the newly cultured soil. ③ was watered after transplantation.

Key points of maintenance of potted flowers in spring

The temperature difference between morning and evening in early spring is very large, sometimes the temperature at night will be below zero, and sometimes there will be late frost or cold snap. At this time, keeping the basin soil dry and doing a good job of anti-freezing is still the key. It is best not to ventilate for a long time, let alone put the plant in the place of air convection. Therefore, potted flowers should come out of the house a little later and not too early in spring, and should be slow rather than urgent. Generally speaking, the method of window ventilation can be taken about 10 days before leaving the room, so that it can gradually adapt to the external temperature; you can leave the room in the morning and enter the room in the afternoon; leave the room in cloudy days, but not in windy days.

Change the pot for sap sprouting potted flowers, such as June snow, pomegranate, rose and other flowers and trees with strong cold protection, planted for several years, the basin has been too small, should be carried out at this time to change the soil. The basin soil should have a certain amount of mountain mud, and other humus soil can be used. For flowers and trees that are blooming or appreciating fruit, they should wait for flowers and fruits to fall, such as kumquat, camellia, rhododendron and so on. For flowers and trees in a semi-dormant state, such as big leaf masts, hanging orchids, etc., pots can be changed before and after the Qingming Festival. For cold-fearing flowers and trees, such as Milan, Zhulan, jasmine, epiphyllum, arrow lotus, as well as most foliage plants such as rubber trees and rich trees, they should continue to keep warm from the cold, and change pots and soil after Qingming Festival.

Pruning according to the growth characteristics of different kinds of flowers, pruning, root pruning, heart-picking and leaf-picking and so on. The rose, mulberry and poinsettia that bloom on the annual branches can be re-cut to remove withered branches, disease and insect branches and overdense branches that affect ventilation and light. For rhododendron, camellia, Yingchun, gardenia, etc., which bloom on biennial branches, it is usually only necessary to cut off diseased and over-dense branches.

Water and fertilizer management to fertilize flowers in early spring, we should grasp the principle of "thin fertilizer less, gradually increase", should apply fully mature thin cake fertilizer and water, the number of times should be from less to more. The time of fertilization in spring should be in the sunny evening.

Early spring watering should also pay attention to the right amount, should see dry and wet, do not water too much at once. In late spring, the temperature is higher, the sun is stronger, the evaporation is larger, watering should be diligent, and the amount of water should also be increased. In short, watering potted flowers in spring should grasp the principle of not drying and watering, watering must be thoroughly watered, and avoid stagnant water in the basin. Watering time should be carried out before noon, and the soil should be loosened in time after each watering.

Breeding in spring is the best time for cutting, planting and sowing potted flowers. Such as rose, geranium, spring, pomegranate, etc., can be cut off robust branches for cutting; orchid, asparagus, orchid, can be propagated; such as mimosa, impatiens, morning glory, string red, peacock, marigold, colorful pepper and other herbaceous flowers, can be sown or on demand for reproduction.

Prevention and control of diseases and insect pests in spring is the season of flowers in full bloom, but it is also the period when diseases and insect pests begin to multiply, so it is necessary to check frequently, detect early, prevent early, and treat early. The common pests in spring are aphids, red spiders, whitefly, shell insects, etc., and the common diseases are powdery mildew, rust, black spot and yellowing. Melon and leaf chrysanthemum, dahlia, impatiens and rose are easy to get powdery mildew; crabapple, rose, peony and bamboo are easy to get rust; peach, rose and plum blossom are vulnerable to aphids; camellia, pomegranate, rhododendron, rose, hibiscus, clove, begonia and evergreen are vulnerable to shell insects, which should be prevented and controlled early.
