Rose Feeds Explained: Choosing and Using the Right Feed for Your English Roses
Caring for English Roses is as much about understanding their needs as it is about admiring their beauty. With the right nourishment at the right time, roses grow with greater strength, produce more abundant blooms, and remain resilient through the changing seasons.
Feeding is a simple but important part of rose care. By providing a steady supply of nutrients, you help your roses build strong roots, healthy foliage and generous flowering throughout the growing season.
Roses are naturally vigorous plants. As they grow, flower and repeat bloom through the season, they gradually use up the nutrients available in the soil. Regular feeding replenishes these nutrients and supports steady, balanced growth.
Well-fed roses tend to develop deeper root systems, stronger stems and fuller foliage. Most noticeably, they reward the gardener with more generous and reliable flowering. Feeding also helps plants remain resilient when facing stress from weather, pests or disease.
Different feeds serve different purposes in the garden. Many gardeners find it helpful to combine a few types over the course of the season.
Common options include:
- Slow- or controlled-release rose fertiliser
- Liquid seaweed feed
- Tomato fertiliser
- Mycorrhizal fungi for planting
Each plays a slightly different role in supporting healthy growth and flowering.
Most feeding begins in early spring, just as roses start to grow again after winter. A slow-release fertiliser applied at this time provides a steady supply of nutrients as the season begins.
Through spring and summer, additional feeds such as liquid seaweed or tomato fertiliser can be used to support healthy growth and encourage flowering. Newly planted roses may also benefit from mycorrhizal fungi at planting time to help establish strong roots.
Slow- or Controlled-Release Rose Feed
A granular slow-release rose fertiliser is often the simplest and most reliable choice for regular feeding. Once applied, it releases nutrients gradually into the soil, providing steady nourishment for several weeks or months.
When to Use
Apply in late March or early April, just before new growth begins.
Why It Works
- Provides consistent nutrition over a long period
- Reduces the need for frequent feeding
- Encourages strong root systems and healthy growth
Step 1With a hand fork, clear away weeds, fallen leaves, and lingering debris from around the base of your rose, leaving the soil neat and open.
Step 2Scatter around 30g of David Austin Rose Food evenly at the base, using the measuring scoop provided. For shrub roses, 30g will suffice; for climbing and rambling roses, offer 60g.
Step 3If the soil is dry, water well to settle everything in. Then follow with mulching for the best results.
Liquid Seaweed Feed
Liquid seaweed is a gentle, natural feed that supports overall plant health. Rather than pushing rapid growth, it helps strengthen roots and improve a plant’s natural resilience.
When to Use
Apply throughout the growing season, particularly if plants are recovering from stress such as drought, transplanting or pruning.
Why It Works
- Encourages healthy root development
- Supports natural resistance to pests and disease
- Suitable for gardeners who prefer organic feeding methods
Tomato Feed
Although designed for tomatoes, this fertiliser is rich in potassium, a nutrient that helps encourage strong flowering. For roses, it can be particularly useful once buds begin to form.
When to Use
Apply during the flowering period in late spring and summer.
Why It Works
- Promotes abundant and well-formed blooms
- Supports plant health during flowering
- Especially helpful for roses grown in pots or containers
Mycorrhizal Fungi
Mycorrhizal fungi form a natural partnership with plant roots. Once established, they extend the root system’s ability to absorb water and nutrients from the soil.
When to Use
Apply when planting new roses or transplanting existing ones.
Why It Works
- Encourages stronger, more extensive root systems
- Improves nutrient and water uptake
- Helps roses establish more successfully in new soil
A Few Tips for Effective Feeding
- Feed at the right time: Begin with a slow-release fertiliser in early spring, then supplement with liquid feeds during the growing season if needed.
- Avoid overfeeding: More fertiliser does not always mean better growth. Follow the recommended quantities for each product.
- Prepare the soil: Clear away weeds, fallen leaves and debris before feeding so nutrients reach the roots more easily.

Mulching Roses in SpringMulching is one of the simplest and most beneficial tasks you can do for your roses each year. In spring, a protective layer placed around the base of the plant helps the soil retain moisture, suppresses weeds and gradually enriches the ground with nutrients as it breaks down.

Training Climbing Roses into Decorative ShapesThere is a distinct charm in allowing a climbing rose to do more than simply cover a surface. A wall awash with bloom is undeniably lovely, yet when a rose is thoughtfully guided into a deliberate form, such as a sweeping arc, a relaxed swag, or a flowing wave, the effect becomes something altogether more expressive. The plant is not constrained, merely encouraged, its natural grace quietly emphasised.
