Maintenance method of potted flowers in autumn and timely sowing.
A year's plan starts with spring. Many people know that spring is best for sowing, but the temperature is moderate in autumn. After sowing in autumn, many flowers will bloom brilliantly in spring after resting in winter.
Autumn is suitable for planting biennial or perennial flowers, such as snapdragon, carnation, chrysanthemum and cyclamen. In addition, common Gerbera jamesonii, delphinium and begonia are very suitable for autumn sowing.
Enter in time
After the cold dew in the northern region, the temperature drops, and there is first frost in the morning and evening. According to the cold resistance of flowers and plants, they should be moved indoors one after another to avoid cold. The specific time to enter the room will vary from flower to flower. For most flowers, the weather in autumn is changeable, hot and cold, so don't rush into the house.
The premature entry of flowers will affect the accumulation of nutrients, which is not conducive to the growth and development of plants in the coming year. Therefore, if it is not cold, you can enter the room later.
Dressing and shaping
After autumn, when the temperature is 20 degrees Celsius, most flowers will sprout. We can set up a framework according to plant types and plant growth, keep some shoots and cut off all others to reduce nutrient consumption.
For the shoots that have just grown and kept, we should also pick the hearts in time so that the branches can grow up quickly before the arrival of winter. Chrysanthemum, dahlia, Chinese rose, jasmine, etc. After these flowers germinate in autumn, when the buds grow to a certain extent, only one bud at the top is kept, and the others are removed.
Proper water and fertilizer
In autumn, many flowers change the decadent ink color in autumn and begin to grow faster. At this time, they need adequate nutrition. But fertilization is also particular. Annual autumn chrysanthemum, osmanthus fragrans, camellia and rhododendron need topdressing for 2-3 times in the whole autumn, mainly phosphate fertilizer. For roses, Milan, jasmine, etc. Flowers bloom many times a year and topdressing 3~4 times. To make sure it keeps blooming.
Matters needing attention in autumn potted flower maintenance: change pots.
After autumn, it is the best time for many flowers to turn over pots and change pots. The flowerpot is very small, and the roots of flowers are densely distributed around the wall of the pot. You can change the soil in Jining, or change it into a cauldron to promote its growth. At the same time, it can be trimmed properly and cut off dead branches and leaves to improve the ornamental value of potted flowers.
relight
The light intensity becomes smaller in autumn, and some flowers that like light can't adapt quickly, so they need to be supplemented in time. Move the plants to a sunny place in the morning and evening to increase the illumination time (for summer use). At the same time of supplementing light, N, P and K combined with nitrogen fertilizer can be applied 1~2 times, which makes the plants grow more robust and improve their cold resistance after overwintering.
Collect seeds
The seeds of many flowers will mature after the Mid-Autumn Festival and need to be harvested in time. After raising flowers for so many years, do you only know how to buy seeds, surrender and be self-sufficient? A bunch of red, dill, morning glory and other seeds (common small wildflowers on the roadside), after harvesting, remove impurities, put them in cloth bags and store them in a ventilated place. Some seeds can be planted immediately after harvesting, harvesting seeds and sowing hope. You can grow flowers at home without spending money on seeds!
