What fertilizer is best for Koelreuteria paniculata

Fertilization time of Koelreuteria paniculata

1. The growing period of Koelreuteria paniculata is short. It sprouts late in spring, so fertilizer should be applied after sprouting. Nitrogen fertilizer should be used mainly and should be applied frequently. Phosphorus and potassium fertilizers should be used mainly in autumn and should be applied frequently.

2. Don't apply too much fertilizer to the tree for the first time. You can use 2500g to 3000g of nitrogen fertilizer per mu. After that, you need to apply fertilizer every 15 days or so, and the amount of fertilizer can be slightly increased.

What fertilizer to use for Koelreuteria paniculata

1. When fertilizing the Koelreuteria tree, it is generally advisable to apply quick-acting fertilizers mainly composed of nitrogen fertilizers. In autumn, the application of nitrogen fertilizers should be stopped, and phosphorus and potassium fertilizers should be increased. This can promote the nutritional growth of the plant, increase the lignification degree of the plant, and improve the cold resistance of the seedlings.

2. In winter, you can apply some organic fertilizer from farmers as base fertilizer to the Koelreuteria tree. It not only provides nutrients for the growth of seedlings, but also improves the soil. As the seedlings grow, the amount of fertilizer should be gradually increased to meet the nutrient needs of the plant growth.

Fertilization method of Koelreuteria paniculata

The Koelreuteria tree has its vigorous growth period between June and September. You can use 0.2% compound fertilizer or urea to water around the roots of the seedlings. Be careful not to water the leaves of the plant. After August, you need to loosen the soil in time. Apply 5-8 kg of compound fertilizer each time to promote the growth of seedlings.

Precautions for fertilizing Koelreuteria paniculata

In late September in autumn, the seedlings of Koelreuteria paniculata have entered the late growth stage. At this time, topdressing should be stopped. 0.3%-0.5% potassium dihydrogen phosphate solution should be sprayed twice every 10-15 days to promote the lignification of the seedlings so that they can safely overwinter.
