Fertilizing Your Roses
There are specific times and methods for fertilizing your roses;
- When to fertilize – You can start to fertilize when you have four to six inches of new growth and see the roses’ first real new leaflets. You must stop fertilizing at least eight weeks before you expect frost or a cold front. Plants with serious deficiencies to better with faster-acting liquid fertilizers than those just needing some maintenance. Apply fertilizer with very little or no nitrogen as it gets closer to falling.
- Granular Fertilizers – Granular fertilizers should be given to older plants as they are hard for younger plants to process. Use liquid fertilizers on younger rose plants.
- Compost and Mulch – Keep in Mind that compost and mulch may rob your plants of nitrogen, so nitrogen may be needed to add.
- Container Roses – Contained roses need to be fertilized with water-soluble liquid fertilizers on a more regular basis.
Features of a Good Fertilizer for Roses
Roses need five basic nutrients, Nitrogen, Potassium, and Phosphorus, besides a small number of other nutrients.
Here is an explanation of the nutrients that you need to look for in a good fertilizer for roses;
- Nitrogen – Roses need Nitrogen first to initially promote healthy and vegetative, green growth. Nitrogen is a component of all proteins, and because water washes it away from the roots of roses, they need a consistent supply. It’s needed for building Chlorophyll and allows the plant to use light to turn to water and carbon dioxides to turn to sugars to feed itself. If you use too much nitrogen, you will have very lush rose bushes with very little blooms; though, if you use too little, your roses may have yellow leaves and very pale roses.
- Phosphorus – Phosphorus is required to promote healthy root development in roses and for abundant flower production. A lack of phosphorus may result in leaves and stems that will drop and weak flowers, with most buds that will not open.
- Potassium (K) – This is also known as potash in some ingredient lists. Potassium K encourages vigorous growth and ensures everything in the rose plant is in excellent working order. It is an immune system booster for roses that helps the plant through stressful times and disease, insect attacks, as well as damage and cold temperatures, A ack of potassium may lead to weak stems, poorly developing buds, and yellow edges on the leaves, which in turn will discolor to brown.
- Other Nutrients – Other Nutrients include Calcium to strengthen cell walls and help roses ward off aphids. Magnesium is crucial to promote dark green leaves and intensify flower colors. Magnesium also flushes harmful salts from the soil. That’s why most gardeners love Epsom salts as a time-honored secret. Sulfur, Boron, Copper, Iron, Manganese, and Zinc are some required nutrients in small amounts for your rose.
