How to plant and cultivate azalea

Rhododendron growth environment requirements

Rhododendron prefers a cool and humid growing environment. It is not resistant to direct sunlight and dryness. It is suitable for planting in acidic soil rich in humus, loose, moist and with a pH value between 5.5 and 6.5. Most species are produced in high altitude areas.

Rhododendron planting time

Rhododendrons are usually planted in early spring and late autumn. They can also be planted in other seasons, but a shade shed must be set up and the soil must be compacted when planting to ensure that the roots and soil are evenly distributed.

How to plant azalea

There are many ways to propagate azalea, mainly cutting propagation, sowing propagation, grafting propagation, division propagation, and layering propagation. Cutting propagation is generally used, which has the largest propagation amount. Layering can produce seedlings faster. Grafting propagation is the most complicated, and only varieties with low cutting survival rates will use grafting. Sowing can cultivate new varieties.

Cutting planting method : When cutting, you should choose branches grown in the current year, about 6-10cm in length. The cut should be smooth. Cut the leaves below and keep 3-4 leaves on the top. In order to make it take root better, you can apply vitamin B12. After it dries, you can cut it.

Key points for planting azalea

Rhododendrons need to be fertilized before and after flowering, and a thin nitrogen and phosphorus fertilizer solution should be applied once or twice a week to promote the growth of branches and leaves and improve the conditions for bud formation.

How to grow azalea quickly

If you want the azalea to grow fast, you need to cut off diseased branches, weak old branches and dense branches. This can increase ventilation and light transmittance, which is beneficial to the growth of the plant, and can regulate its growth and development, making it grow more vigorously.

Azalea cultivation precautions

If you want to grow azalea well, the most important thing to pay attention to is water. You need to give it water with a pH value below 7.0 and the water temperature should also be appropriate. You should replenish water in time and not let the soil dry out. In addition, you must prevent and control diseases and pests in time, and pick off the remaining flowers after the flowers wither.
