How to Fertilize Roses: Ways to Keep Them Happy

Michelle - December 19, 2020

The rose is considered the most beautiful flower, which is why it’s called the “queen of the garden.”

Roses are most commonly associated with love and romance, which are always the most popular bouquet to give to someone. It can also mean secrecy or confidentiality.

Each color of the roses symbolizes a different meaning. However, we cannot deny the fact that roses emit beautiful positive feelings. Roses established a strong base in human thoughts, minds, and hearts.

When counting down the top 20 most beautiful flowers in the world, roses can be on the top list. However, growing roses will present you with thorny matters.

Roses are very delicate. They are considered one of the plants that need high-maintenance care, as they are prone to insect infestations.

Your roses need two things: sun and water.

Why do flowering plants need light? All living things need food and water. Light helps plants produce food, while water helps transport and distribute nutrients and other substances necessary for their health and growth.

Nutrients roses need

The primary nutrients (macronutrients) that all plants need are nitrogen (N), phosphorus (P), and potassium (K).

- Roses require nitrogen in the soil to grow tall and keep their leaves green. Since a rose’s ability to make flowers resides in its leaves, healthy foliage results in more flowers. Too much nitrogen will result in too much foliage and fewer blooms, while not enough nitrogen results in yellow leaves, stunted growth, and smaller blooms.

- Phosphorus promotes healthy root development and abundant flower production. Phosphorus serves an equally important purpose. It takes care of the roses’ roots, ensuring they’re well enough to absorb nutrients from the soil. It also supports the transfer of energy throughout the plant for root development and flowering. A shortage of phosphorus can result in leaf drop, weak flower stems, and buds that won’t open.

- Potassium, also referred to as potash, helps roses recover when stressed by insect and disease damage or by extreme weather conditions. Lack of potassium can result in yellow leaf margins, weak flower stems, and poorly developed buds. However, excessive potassium causes chlorosis, poor root growth, and wilted new shoots.

- Other nutrients: In order to thrive, roses also need micronutrients, including calcium, magnesium, sulfur, boron, copper, iron, manganese, and zinc.

It is true that planting and growing roses need extra care. Fertilizers are needed to make your rose grow healthy and beautiful. There are two basic types of rose fertilizers, organic and inorganic.

Organic fertilizers, which are derived from plant or animal matter, are better for the environment. Organic fertilizers include manures, compost, or other plant and animal products (alfalfa, bone meal, fish fertilizer, kelp extract, etc.).

Inorganic fertilizers also are referred to as artificial or artificial fertilizers. They are ready-to-use and convenient, more concentrated, and often less expensive than organic.

However, these products don’t improve soil and have no positive residual effect. Some also contain insecticides and should be avoided altogether, as they can harm wildlife. Fertilizers are good sources of nutrients for plants. However, too much of it can also be harmful to the plants.

Organic Rose Fertilizers

Compost promotes overall plant health, helping roses to be more resilient to pests and diseases.

Compost improves the texture of your garden soil, allowing it to hold both water and air better. It also adds nutrients and promotes healthy root development in garden plants.

Mix into the soil at planting time, or apply a 1- to 2-inch layer each spring around the base of established rose plants.

- When using manure (other than commercially processed products) in the home garden, it is best to allow it to age first for 6 months to avoid any potential problems. Manure can be worked into the soil at the time of planting or mulch established rose plants with a one-inch layer in spring.

- Make sure manure is well-aged, so it doesn’t burn plants. Well-rotted farmyard or horse manure is excellent but do make sure that it is at least three to four years old, as fresh manure can burn the roots of plants.

- Before applying your chosen compost material, make sure the ground is diseased-free, and you watered your roses. Manure teas also work well.

- Avoid manure from animals that eat meat. You can also use chicken manure sparingly - as these are too acidic for roses.

- Bone meal can be applied in spring for a slow-release effect through the growing season and again in fall to promote root growth and next year’s flowers.

- Fish fertilizer can be used as an all-purpose fertilizer and promotes lush growth. It also provides an excellent nitrogen source. It is safe for all plants and will not burn the roots.

- To use as the primary fertilizer, apply every 3 weeks during the growing season; often used in combination with kelp.

- Alfalfa is one of the best overall organic amendments, resulting in more vigorous growth and increased bloom production.

- Coffee grounds can be sprinkled around the base of rose bushes at any time during the growing season for a boost of nitrogen. Coffee is acidic, so soil pH may need to be adjusted with lime or other alkaline sources.

- Epsom salts, seaweed extracts, cottonseed meal, and coffee grounds are organic fertilizers available out there in the market. These can be used in your rose flowering.

Inorganic Rose Fertilizers

Since inorganic fertilizers are more concentrated than organic fertilizers, don’t pile them up on dry soil, which can cause a burn. Instead, spread the fertilizer thinly and evenly around the plant and lightly rake it into the damp or wet soil.

The best time to apply the fertilizer is just before it rains or before watering. Keep the fertilizer away from the canes and the graft union, and water the plants well after applying fertilizer.

The rule of thumb is about half a cup per plant for controlled-release fertilizer unless specified otherwise on the product label. Liquid fertilizer provides a quick boost of plant food in the short term, usually requiring reapplication every two weeks or so. There are many options for roses liquid fertilizer.

Fertilizing does not need to be hard, especially when you have the right tools for it. A high-performing sprayer is your best bet when it comes to fertilizing your roses and other plants, too.
