Rose Season: The Ultimate Guide to Fertilising Roses – How, Why and When

There’s something truly magical about rose season. As gardens come alive with colour and fragrance, roses emerge as the stars of the season, gracing borders, beds, and containers with their timeless beauty. But behind every stunning rose display lies one essential ingredient: proper feeding.

To help your roses reach their full potential, fertilising is key. And if you’re looking for a simple, effective, and mess-free way to nourish your roses, Devonia Rose Plant Fertiliser Sticks are a perfect solution

Why Fertilise Roses?

Roses are heavy feeders. While they may survive without extra nutrients, they certainly won’t thrive. Regular feeding supports:

  • Stronger growth – lush, healthy foliage and robust stems
  • More flowers – richer colour, fuller flowers, and longer flowering periods
  • Disease resistance – a well-fed rose is better equipped to fend off common issues like black spot and mildew.
  • Improved root health – essential for water and nutrient uptake

Whether you’re nurturing a heritage climber, a compact patio rose, or a classic hybrid tea rose, all roses benefit from a good feeding regime.

When to Fertilise Roses

Timing your rose feeding correctly is just as important as what you feed them. Roses need a steady supply of nutrients throughout the growing season, especially when they are putting out new growth and producing flowers.

Here’s a simple timeline to follow:

  • First Feed – March/April: As soon as new growth begins in spring, it’s time to feed. This kick-starts the plant’s energy reserves and supports healthy foliage and early bud development.
  • Second Feed – Late May to Early June: After the first flush of flowers, roses benefit from another round of nutrients to encourage repeat flowering and to keep energy levels high.
  • Third Feed – July/August: For repeat-flowering varieties, a third feed will carry them through the late summer bloom period.

With our Rose Fertiliser Sticks, feeding is refreshingly easy. Each stick feeds for 60 days, so you can stay on top of your feeding schedule with a simple routine: feed in March, May, and July – and let the spikes do the work.

How to Fertilise Roses – The Easy Way

Traditional rose feeding methods can be a bit of a hassle: messy powders, smelly liquid feeds, precise measuring, and the risk of overdoing it. That’s where our Rose Plant Fertiliser Sticks really shine.

Why Devonia Fertiliser Sticks Are Different:

  • No Mess, No Smell – Unlike many other fertilisers, these solid sticks eliminate the mess and odour often associated with plant food. No splashing, no mixing, no smelly hands.
  • Zero Waste, No Wash-Away – Liquid and granular feeds often wash away when watering. Devonia’s stick formula stays put, ensuring consistent feeding at the root zone – where your roses need it most.
  • Pre-measured, No Guesswork – Overfeeding can harm your roses. These pre-measured sticks take all the uncertainty out of feeding. Just insert and forget.
  • Long-Lasting Power – Each stick feeds your rose for up to 60 days. That means you only need to feed every two months.
  • Suitable for All Roses – Whether it’s climbing, shrub, patio, or floribunda, Devonia sticks support them all.

How to Use Devonia Fertiliser Sticks:

  • Pick your plant – For best results, start in early spring when your rose shows signs of new growth.
  • Insert the stick – Push one or more sticks (see pack guidelines) into the soil near the base of your plant, roughly halfway between the stem and the outer edge of the pot or planting area.
  • Water as usual – There’s no need to alter your watering routine. The slow-release formula will do its work over the next 60 days.
  • Repeat every 2 months – For continuous support, simply replace the sticks every 60 days, right through the flowering season.

Each pack of 20 sticks offers excellent value and keeps your roses fed for months on end.

Feeding Roses in Pots versus the Ground

Roses grown in containers often need extra attention when it comes to feeding. Because nutrients in pots are used up (or washed out) more quickly, a consistent and long-lasting feed like Devonia Fertiliser Sticks is especially useful.

In beds or borders, roses also benefit from targeted feeding, and sticks are ideal because they provide steady root-zone nutrition without feeding surrounding weeds.

Tips for Healthier Roses

  • Mulch after feeding – A layer of organic mulch helps retain moisture and improve soil health.
  • Deadhead regularly – Removing spent flowers encourages more flowering.
  • Water wisely – Deep, infrequent watering is better than frequent sprinkling.
  • Feed consistently – Roses are grateful for a dependable schedule.

Roses reward care with unmatched beauty and feeding is one of the most important parts of rose care. With Devonia Rose Plant Fertiliser Sticks, you get all the benefits of a professional-grade feed without any of the fuss.

So this rose season, give your garden’s star performers the nutrients they need – and enjoy a summer full of breathtaking flowers!
