Roses are common flowers with a long blooming period. To ensure your roses bloom frequently and produce abundant, large flowers, proper fertilization is essential. So, what kind of fertilizer will make roses produce more and larger blooms? Let's find out below.
1. Potassium dihydrogen phosphate
Potassium dihydrogen phosphate not only promotes flower bud germination, resulting in more rose blooms, but also accelerates the maturation of new buds in winter, protecting roses from frost damage. To ensure roses bloom, it is essential to strengthen fertilizer and water management, spraying with a 0.2% solution of potassium dihydrogen phosphate every half month for two consecutive times.
2. Chicken manure
Chicken manure contains numerous trace elements that can promote flower growth. Using it before and during the blooming of roses can encourage more blooms, resulting in larger and more vibrant flowers. After processing, place the chicken manure in the sun to dry, as dampness can lead to the proliferation of bacteria. Then, add the sun-dried chicken manure to the rose pot and cover it with sand. Roses thrive on fertilizer and can be fertilized once a month; the manure will gradually release organic matter during watering for the plant to absorb.
3. Oilseed cake fertilizer
Oilseed cake is a favorite fertilizer for roses. It can be purchased at some oil mills and is typically made from soybean cake, peanut cake, sesame cake , etc. Crush the oilseed cake and mix it with garden soil in a 1:1 ratio. Place the mixture in a plastic bag, spray with water, and squeeze the soil with your hands; it should clump together but not release excess water. Place the sealed bag in the sun to dry for about a week to obtain fully decomposed oilseed cake. Oilseed cake is rich in nitrogen, phosphorus, potassium, and other nutrients. Using it as a base fertilizer or top dressing for roses promotes healthy growth and abundant blooms.
4. Bone meal
When you eat pork ribs at home, don't throw away the leftover bones. After pressure cooking them, dry them in the sun, and then crush them with a hammer. This bone meal fertilizer is perfect for roses. Dig a trench around your rose bushes, sprinkle in the bone meal, and cover it with soil. The bone meal is rich in phosphorus, which will slowly release its nutrients during the rose's growth process, allowing the rose to absorb and utilize them.
5. Traditional Chinese medicine residue fertilizer
Chinese medicine residue is a clean and nutrient-rich fertilizer that can be mixed into potting soil. If it is soaked and fermented into well-rotted fertilizer, the effect will be even better.
6. Eggshell fertilizer
Many people like to use eggshells, but you shouldn't just put the whole eggshell on the pot. You need to crush the eggshells, expose them to the sun, and then bury them in the pot. This will help the roses bloom.
