Discover the art of rose fertilization, an important aspect of rose care that begins right at the time of planting. Learn about your options, from slow-release granules to organic manure and compost.
Fertilization Timing and Frequency
While roses will demand nutrients during their vegetation period from March till early autumn, it’s not advisable to fertilize them during winter. Given the plant’s dormant state, it will not absorb the nutrients.
On the other hand, the frequency of fertilization depends on the type of fertilizer you choose. For instance, liquid fertilizers can be applied every 15 days. Beneficially, the minerals in these fertilizers are immediately accessible for the plant.
Alternatively, granular fertilizers, known for their slow-release nature, will require application every three months. Hence, a rose bush could get fertilized three times during its vegetation period: early spring, summer, and early autumn.
Types of Fertilizers
You can choose from a range of commercial and natural fertilizers for roses. Commercial fertilizers are available in liquid and granular form. The liquid formula is straightforward to use, just ensure the soil is damp to prevent root burn. Meanwhile, applying granular fertilizer involves scratching the substrate around the bush before application. Always pay attention to the dosage recommendations on the packaging.
Autumn Fertilizer for Roses
For the autumn season, you can opt for potassium-rich fertilizer, ideal for generous blooming. These fertilizers can either be readily bought or naturally produced.
Natural Fertilizer Options
For those who prefer an organic approach, natural fertilizers like white vinegar, banana skins, and coffee grounds are excellent choices. The white vinegar not only gives a boost to roses but also repels pests and eliminates weeds.
On the other hand, banana skins, rich in potassium, also release calcium and magnesium as they decompose. Coffee grounds, besides stimulating plant development, are also useful in keeping cats at bay.
