Plant food for roses.
This arrived in packaging which had been wrapped over the original packing. The box is quite badly damaged and I have had the rose food everywhere. The product itself seems to be very good, my roses are quite happy.

Bringing the Garden Back to Life: A Reliable Boost for My Roses and Shrubs
After a particularly dull season in my garden where my roses and flowering shrubs looked more tired than thriving, I decided to give the AMK® Phostrogen Toprose Rose and Shrub Feed a try—and I’m genuinely glad I did. I’ve used various plant foods over the years with mixed results, but this one offered noticeable improvements within just a few weeks of application.The 1kg size is generous and should last through the growing season for a modest-sized garden like mine. I mainly applied it to my rose bushes and a few hydrangeas that had been struggling with slow growth and underwhelming blooms. The granular texture makes it easy to apply directly around the base of plants—there’s no complicated mixing or need for a feeding can if you’re short on time. I sprinkled it on just before a rainy spell, and nature did the rest.What impressed me first was the subtle change in the foliage. My roses in particular began to produce richer, greener leaves within two weeks, and even the smaller, struggling bush at the edge of my garden perked up noticeably. The new leaves appeared glossier and fuller, and the overall look of the plant was visibly more vigorous. Over the following weeks, the bloom count improved too—more buds, better colour, and longer-lasting flowers. The difference in vibrancy was enough for a friend to comment during a visit, which speaks volumes.One of my favourite things about this feed is that it doesn’t have an overpowering smell like some other garden products. It’s pleasant to use and doesn’t feel like a chore. I’ve also noticed that the plants seem to be more resistant to the pests and fungal issues I usually battle every summer, which I suspect is partly due to the improved strength and resilience that comes from being properly nourished.The shrubs that I had sort of written off as permanently underperforming have started to look like part of the garden again, not just filler. I’m not saying it’s a miracle cure, but the difference with regular use (about every 4–6 weeks) is undeniable.For those who love their garden but don't want to overcomplicate feeding schedules or invest in a million different products, this Toprose feed is a really practical, effective solution. It’s a product that delivers what it promises—stronger, healthier plants and more reliable blooming. I’ve already picked up a second pack to make sure I’m stocked for the rest of the season.If your roses are looking a bit sad or your flowering shrubs aren't pulling their weight, this is absolutely worth a try. It's straightforward, dependable, and has brought real results to my garden.

AMK® Phostrogen Toprose Rose and Shrub Feed 1kg Fertiliser Food for Stronger Healthier Plants
Really could see difference on my roses. I have tested this product on two roses which were not doing well at all. Now they looks soo much better and healthy and they have actually flowers which I could not remember when I have seen them last time. Really happy with the product and happy to recommend it. Worked very well for me so hope it will for you. The result came after 2weeks of application to be honest. Thank you

Easy straight forward to use
Easy and straight forward to use rose and shrub feed, which come packaged within a really convenient 1kg cardboard box. The box has a pull on the side so you can easily pour the feed out and then reseal it again.The consistency of the feed is granular, so easy to dispute around the plant or mix in at root level. This feed can be used in multiple ways and only needs to be applied across two seasons’ spring and summer according to the instructions. So depending on how many plants you have, this box should last a few uses. My roses have just survived winter again so hoping this feed does them some good but, it’s going to be a while until I see any results from this feed.Overall, very easy to use feed and takes up little room to store in its packaging. This product will take a while to see the overall results but so far really happy with the feed.

Fantastic experience overall. Will recommend to friends and family.
1. Scatter the granules onto the soil surface around your roses. 2. Water the granules in to help improve root development and encourage efficient nutrient absorption. 3. Use when transplanting new rose bushes and shrubs to help them survive the process. 4. For a complete rose care solution, use with Toprose Bug Killer and Toprose Fungus Control & Protect for stunning, healthy roses.
Safety Warning
