How to make and use rose fertilizer

Suitable fertilizer for roses

If you want to apply base fertilizer when planting roses, the more commonly used flower fertilizer is organic fertilizer. Usually, oil cake, bone meal or decomposed fertilizer can be used, which is beneficial to the growth of the plant.

Wood ash is more suitable for roses, as it contains a very high potassium content. If you apply some wood ash during the flowering period, the flowers can be made larger and brighter. Or you can use animal manure on the plants, which is a purely natural fertilizer with sufficient nutrients that can provide nutrients for the plants to maintain growth.

How to make rose fertilizer

An organic fertilizer made from river mud, straw, animal excrement, grass, green manure and other plant organic matter, which is mixed and then decomposed and fermented by anaerobic microorganisms under flooding conditions.

How to use rose fertilizer

1. Apply enough basal fertilizer

When planting roses, sufficient base fertilizer needs to be applied. The base fertilizer is generally mainly organic fertilizer. Usually, fully decomposed organic fertilizer is applied, and then combined with high-concentration compound fertilizer. The base fertilizer is generally used after the leaves fall in autumn, and the method is to apply it by digging trenches.

2. Apply fertilizer at the right time

Roses have a relatively high demand for fertilizer during their growth process, and generally require timely application of quick-acting fertilizers, usually about three to four times a year.

Too much fertilizer for roses

If roses lose leaves due to overuse of fertilizer, you can water them with plenty of clean water to rinse them. This way, the fertilizer will be diluted and flow out with the water, thus avoiding fertilizer damage. If the situation is serious, it is best to change the soil as soon as possible and use new soil to avoid root rot.

Precautions for fertilizing roses

1. Potted roses should be mainly fertilized with light fertilizers, and special attention should be paid to not using strong fertilizers, especially chemical fertilizers, which will cause partial root rot and dry up and lose vitality.

2. The amount of fertilizer for roses should be determined according to the size of the flowers and pots. Every month and a half, some compound fertilizer or nitrogen fertilizer should be used, and it should be evenly sprinkled on the soil beside the pot. Alternatively, water the roses about 1 to 2 times a month. Rice washing water that has been fully fermented can be used as a light water fertilizer.
