About Ultimate Rose Bloom Booster

Completely transform the way you grow roses with the Ultimate Rose 'Bloom-Booster' Complete Fertiliser. This extraordinary blend of nutrients and natural enhancers is the secret behind the lush, vibrant blooms we come to expect in our gardens.

Now, we've been growing roses professionally for years and we don't say this lightly. This isn't your average feed. It's been tested, proven and perfected with one aim: to help UK gardeners grow the most glorious roses possible.

And the results really do speak for themselves. So what's the magic? The formula is packed with five powerful components; a Natural Organic Fertiliser, Mycorrhizal Fungi, Slow-Release and Controlled-Release Nutrition, plus a Bio-Stimulant.

Each one plays a role in building stronger roots, richer colour, and longer flowering. It feeds deeply and steadily, releasing nutrients across the whole growing season.

Whether you're planting a brand-new Hybrid Tea or giving a tired old Floribunda a spring wake-up call, this fertiliser makes all the difference. You'll see richer foliage, more blooms, better shape, and you won't have to constantly reapply.

And here's the kicker: it's so easy to use. Just one annual application at planting or in spring is enough to fuel exceptional results. It's a quick, affordable and foolproof way to see what your roses are really capable of.

So here's your moment. Either continue growing as usual, or take the leap and experience the rose garden you've always imagined.

To use: Shake the pack while closed to remix the product ingredients, as some settlement may have taken place while in storage or transport. In March and April, apply to the soil around the plant, or at time of planting. For dosage, use 30g of fertiliser for a shrub rose or shrub, or 60g for a climbing rose.

Planting new roses - Sprinkle 30g evenly into a prepared planting hole and mix in at the outside of the hole.

For top dressing - Clear soil of any leaves, weeds, or debris. Work the soil so it is open to a depth of 5-10cm. Apply 30g of fertiliser evenly around the plant, about 15cm away from the stem and then work into the topsoil so all product disappears. After fertilising, apply 5L of water per plant to help incorporate the fertiliser into the soil.
