How to cultivate potted rhododendron

I. Matrix:

Because the roots of this kind of plant are very fine, we had better choose some loose soil when selecting the cultivation substrate, whether it is drainage or irrigation. Generally, we use fine-grained soil such as rotten leaf soil or peat soil plus coarse-grained perlite, which are generally mixed evenly to form the culture soil of the plant. Before transplanting to the basin, you can put a little bit of bone powder on the substrate as the base fertilizer, and then cut off some old dead branches, which is conducive to the germination of new roots.

2. Ventilation:

The potted plants should be placed outside the house in a well-ventilated place, not in a hot and poorly ventilated place, and not in a closed room, otherwise the leaves of the plant will turn yellow and fall until death.

3. Lighting:

This kind of flower does not need too strong light, just scatter the light, in addition, when the temperature is above 35 degrees, you should pay attention to shading it.

Four. Fat and water:

1. Because its roots are relatively weak, and afraid of waterlogging, but also can not adapt to the lack of water, so the soil is too dry or too wet will cause its poor growth. So wait for the basin soil to dry before you drench it. If you don't dry, don't worry about it. Dormant in winter, so you need to stop the supply of water and fertilizer, if the temperature is high, you can be drenched every 3 to 5 days. Once a day when it blossoms. Summer not only replenishes water, but also sprays branches and leaves and the ground. Just keep the basin soil moist in autumn.

two。 Machine fertilizer is mainly used when fertilizing, and thin fertilizer can be added every other week in the peak growing season, and some special solution is sprayed when gestating the bud to make the flowers more colorful. Fertilizer should be stopped in summer and during flowering, and phosphorus and potassium fertilizer should be added twice after flowering.

5. Pruning:

It grows slowly and does not need to be cut when it is young, but after a few years, when the branches grow more, we need to cut off the delicate, diseased branches that are too long in early spring, cut off the axillary buds around the buds and concentrate nutrients. After blooming every year, it is necessary to prune the residual flowers to ensure the retention of nutrients, which is conducive to the flowering of the following year.
