Cultivation skills of rhododendron daily maintenance of rhododendron

There may not be many people who have seen this kind of plant, so let's take a look at the cultivation skills and daily maintenance of Maojuan's rhododendron.

Cuckoos like cool, moist and sunny environments. Cold-resistant, heat-resistant, semi-overcast, not resistant to long-term strong light exposure. The suitable temperature for growth is 15-28 ℃ and can withstand low temperature of-8 ℃ in winter. The soil should be acid sandy loam which is fertile, loose and well drained. Traditional varieties include "Jade Butterfly", "Purple Butterfly", "Ryukyu Red", "Yuling" and so on. Rhododendron, summer cuckoo, western rhododendron, honeysuckle, Yunyin rhododendron.

The rhododendron is planted in pieces, and the flowers are colorful and colorful, which can add to the natural landscape effect of the garden. From large trees (up to more than 20m in height) to small shrubs (only 10cm-20cm in height), the trunk is erect or creeping, with alternate or whorled branches.

Cultivation techniques of rhododendron

Basin soil

Acidic soil is required to be loose, well drained and rich in humus. Take 4 parts of humus soil, 2 parts of old basin soil, 1 part of sandy soil, 1 part of burning soil and 1 part of sawdust, mix with proper amount of cake fertilizer and compost for half a month.

Upper basin

When potting, the seedlings take more soil, less damage to the roots, the long roots are shortened appropriately, and the larger plants should be pruned to the upper branches. First, cover the drainage hole of the basin bottom with broken tiles in the flowerpot, spread a layer of coarse-grained soil as the drainage layer, fill part of the culture soil in the center, put the plant into the pot and add soil to compaction. The planting depth is the same as that when the original seedlings were unearthed. Water it thoroughly.

Watering

Afraid of both dryness and waterlogging. From the end of November to the middle and early February of the following year, most of the open-field potted rhododendrons were dormant or semi-dormant, and they were properly watered according to the dry and wet condition of the basin soil. The temperature rose in late February, the flower buds and leaf buds sprouted, and the watering times were increased appropriately. The peak period of new shoot growth is from March to June, and the water demand increases, so it is necessary to increase the watering times. The temperature is high from July to September and it has to be watered every day. After October, the amount of water can be reduced.

Fertilizer application

If you don't like big fertilizer, you should apply thin fertilizer frequently. Base fertilizer with long-acting fertilizer, such as cake fertilizer, bone meal and dry stable manure and other organic fertilizer, in the upper basin to change the basin or buried in the basin soil in winter. Topdressing with quick-acting fertilizer, such as human manure organic fertilizer or nitrogen, phosphorus, potassium fertilizer, the Beginning of Spring before flowering, apply phosphorus and potassium fertilizer 1-2 times a month, stop fertilization when flowering. Apply liquid fertilizer mainly with phosphate fertilizer for 1-2 times after cool autumn, and stop topdressing after winter.

Key points of cultivation

Potted plants change pots after flowering every spring and use acidic soil rich in humus. Usually watering should be timely, especially at the flowering stage, to keep the pot soil dry. Fertilizer and water is the key to growth and development, fertilizing once every semimonthly or using Huiyou 21-7-7 acid fertilizer. Growth is basically stagnant in winter, so fertilizer and water should be strictly controlled. During the growing period, it is necessary to prune and remove withered branches and sprouting branches, which is conducive to the balanced development of the tree. The planting chooses the acidic soil with high dryness, sufficient sunshine and deep soil layer. Fertilize once a year before and after flowering, cut off the overdense bore branches, truncate only long branches, and cut off dead and diseased branches.

Newly decorated houses are not suitable for raising cuckoos, because harmful gases such as formaldehyde in decorated houses have not dissipated, which is easy to cause harm to cuckoos. Cuckoos and cuckoos are difficult to raise flowers, so it is necessary to carefully grasp the habits of flowers when planting rhododendrons.
