How to fertilize roses

1. First planting

If it is the first time to plant, when the seedlings are larger, organic fertilizer or some medium mixed with pine peat should be applied as fertilizer. Cake fertilizer, bone meal and other organic fertilizers can also be used. When applying, 20 to 50 grams of fertilizer can be placed in a 20-centimeter pot. Be careful not to use too much.

2. One or two years

One-year or two-year-old plants should be applied with a high concentration of cake fertilizer or a continuously effective organic fertilizer before winter. For example, well-rotted cake fertilizer will do. You need to turn the soil over and apply it so that there are enough nutrients during the winter. It does not need to be applied during dormancy.

3. Ground Planting

If the plant is planted on the ground, dig a circular trench around the rhizome after pruning. Depending on the specific size of the plant, bury 200 to 300 grams of fertilizer cake for each plant. You can also apply about 500 grams of animal manure. This will meet the nutrients needed in the second year.

4. Potted Planting

After pruning, potted plants should be removed from the pots, withered and rotten roots should be cut off, and new nutrient soil should be replaced. At this time, 50 to 100 kg of fertilizer cake can be buried in the lower middle part of the pot to meet the growth needs of the second year.
