Firethorn is an evergreen shrub, a small tree, generally used as a hedge in the courtyard of the home, landscaping will use it, because of the high ornamental value of firethorn after fruiting, many friends will also plant potted firethorn. But in the process of planting firethorn, there will be no fruit. So what should I do if the potted firethorn does not bear fruit?
1. Maintenance during flowering.
In the flowering period of firethorn, especially the differentiation period of flower buds, watering must not be too much, as long as the potting soil is moist, you can spray more water to the foliage. In addition, some phosphorus and potassium fertilizers can be sprayed to promote the growth of flower buds and give sufficient light.
2. Reasonable pruning.
The flowering branches of firethorn are mostly short annual branches, and the new branches of the year generally do not open. When pruning, be careful not to cut short branches by mistake, you can cut off the long branches, cut off the rainy branches, and prune the branches and leaves in August.
3. Temperature management.
Because there may be low or high temperatures in winter and summer, it is important to manage the temperature during these two seasons. In summer, when the temperature is high, take measures to cool down, spray water or shade the light. In winter, the temperature should be kept at about 5, and it should be noted that the temperature in winter should not be too high, otherwise it will affect the dormancy of the plants.
Fourth, scientific fertilization.
Fertilization is mainly done in two aspects, the growing season and the flower bud differentiation period. Reasonable application of nitrogen, phosphorus and potassium fertilizers during the growing season can promote the growth of firethorn and store nutrients for flowering and fruiting. During the flower bud differentiation period and the subsequent flowering and fruiting, more phosphate and potassium fertilizers need to be applied, so that the flowering is good and the fruit is more vigorous.
Fifth, change the pot. Firethorn can choose a pot of the right size and caliber, and the material can be a tile pot, a clay pot, or a plastic pot. The soil can be configured with nutrient soil, the garden soil, sandy soil mixed with a little compound fertilizer, configured into a substrate, in addition to putting the substrate on the pot, you can also add broken tiles at the bottom of the pot.
The firethorn plants are removed, the old roots and soil are removed, and the pot is carried out. When potting, put a few broken tiles in the pot, spread a layer of coarse sand, and put in the prepared substrate. Unfold the root system of firethorn, place it in the soil, and fill it with soil, taking care that the soil is uniform and compacted, and not overfilled. After the firethorn is repotted, it should be watered and kept in a cool place for about 10 days, after which it can be managed normally.
When watering potted firethorn, we must pay attention to the time, not too long, not too much, otherwise it may cause the phenomenon of plant death and lead to no fruit.
