Many people may not know what Kerria japonica is. In fact, Kerria japonica is a very beautiful flowering plant that is relatively rare in daily life. Its petals are yellow, small and delicate, and it has extremely high ornamental value. Quite a few people like to grow Kerria japonica as a potted plant at home, so how exactly should Kerria japonica be cared for and managed?
How to grow Kerria japonica
Fertilizer application: During the growing season, fertilize Kerria japonica once every 2 months, and carry out a complete renewal once every 2-3 years.
Key watering points: Kerria japonica likes a moist environment, so attention should be paid to timely watering. From before spring bud break to the flowering period, it can be watered 2-3 times. During summer drought, it can be watered 3-4 times. During the rainy season, attention should be paid to drainage. Before frost, water once with antifreeze water. During the growing season, fertilize once every 2 months. Before spring bud break or after leaf fall in autumn, fertilize once at the root zone so that the plant grows robustly and has abundant flowers and lush leaves.
Pruning essentials: Because its branches are dense, slender and weak, and easily age, Kerria japonica must be renewal-pruned once every 2-3 years, cutting off old, weak and damaged branches to restore growth vigor and encourage more flowering shoots. When dieback branches are found (branches gradually die from top to bottom), immediately cut off the dead branches, otherwise they will spread to the roots and cause the death of the whole plant. After flowering, leave 50cm of height and cut off the upper branches to encourage underground buds to sprout. After Kerria japonica loses its leaves, dead branches may still appear. In the second year in spring (February-March), choose several consecutive sunny days for pruning so that the current year's branches bloom vigorously. If more branches are desired, leave only about 7cm and cut off the rest. In cold regions, repot potted plants about once every 3 years, combining root trimming, division and renewal of old and weak branches.
Potting soil replacement: Transplanting or repotting Kerria japonica is best done before spring germination (February to March) or during October, and the original soil should be kept. When transplanting, apply base fertilizer to encourage more new branches and more flower buds.
Kerria japonica cultivation methods and precautions
1. Cultivation methods:
1. Soil. Kerria japonica does not have strict soil requirements. It grows best in fertile, loose sandy loam, and the soil needs to remain well-drained, soft and non-alkaline.
2. Water. Kerria japonica generally does not need much watering, but in summer when the temperature is too high and water evaporates too quickly, the amount of watering should be appropriately increased to prevent the potting soil from becoming too dry.
3. Temperature. Kerria japonica likes a warm and humid environment, so in winter it should be brought indoors to overwinter.
4. Fertilization. Potted Kerria japonica needs to be watered with cake fertilizer solution in the afternoon, but not too much. During the growing season of Kerria japonica, apply 1-2 additional applications of liquid fertilizer as appropriate according to the plant's growth condition.
2. Precautions:
When dieback branches are found on Kerria japonica (branches gradually dying from top to bottom), the dead branches must be cut off immediately, otherwise once they spread to the roots, they will cause the death of the whole plant. After Kerria japonica loses its leaves, dead branches may still appear, and more pruning should also be done at this time.
Kerria japonica shaping and pruning methods
Kerria japonica likes a sunny and warm environment, is also fairly shade-tolerant, not very cold-tolerant, but relatively moisture-tolerant. To make Kerria japonica bloom abundantly every year, reasonable pruning must be carried out every year.
Pruning is carried out from January to February. Cut off dead branches, excessively dense branches, old branches that are hard at the base and have turned white, and other branches from the base. Carry out plant renewal once every 5-10 years. After flowering, leave 10-15cm above the ground and cut off all the rest.
After Kerria japonica finishes flowering, leave the branches about 50cm high and cut off the upper half of the branches. This can encourage new buds from the underground part to sprout.
In the second year in spring, around February to March, choose consecutive sunny days and prune Kerria japonica over several days. This can make the current year's branches bloom more vigorously and increase the number of flowers.
If you want Kerria japonica to have more branches, you can keep only 7cm and cut off the remaining part.
Kerria japonica propagation methods
Propagate by division, cuttings and sowing.
1. Division: The main propagation method is division. The mother plant does not need to be dug up. Carry it out in early spring and late autumn. Use a knife or spade to directly separate new plants each with 1-2 branches from the mother plant in the soil and take them out for transplanting. The mother plant left in the soil can be divided again the next year. Double-flowered Kerria japonica is suitable for the division propagation method.
2. Cuttings: Use early spring cuttings, with hardwood cuttings (March) using one-year-old branches that have not sprouted. In the plum rain season, around June, use softwood cuttings, using robust current-year branches, leaving half the leaves, with cuttings 12-450px long, inserted into brown soil, mature soil or sandy soil. If inserted in the open field, shade is needed to prevent drying.
3. Sowing: The sowing propagation method is only used when mass-propagating the single-flowered original species. After the seeds are harvested, they need to undergo cold stratification in sand at 5°C for 1-2 months, and be sown the following spring. After sowing, cover with fine soil and mulch with grass. After seedlings emerge, build a shade frame.
As mentioned above, although Kerria japonica is beautiful and charming, it also needs careful care! If you grow some Kerria japonica in your home courtyard, balcony or room, when it blooms it will absolutely be a beautiful scenic line. Hurry and plant some!
