About Swell Gell & Feed

If you've ever come back to parched pots or limp, lifeless baskets after a hot weekend away, you're not alone. We've all been there! Fear not, this is a real game-changer for what goes under the compost, not just into it.

Introducing Blooming Fast Swell Gel & Feed, a breakthrough formula that's nothing short of magic for containers, tubs and hanging baskets. This clever little blend holds water like a sponge, then slowly releases it where your plants need it most: right at the roots.

And as if that wasn't clever enough, it also contains a tried-and-tested slow-release fertiliser that keeps plants thriving for a full 6 months. This is the exact kind of water-retention and feeding tech used in the commercial growing world, and now it's yours, in a ready-to-use, easy-to-measure form.

Just mix a few scoops into your compost at planting time, and it quietly gets to work, saving you time, water and effort all season long. Healthier plants, more flowers, less watering.

Imagine not having to dash out with the watering can every evening, yet still enjoying baskets that are overflowing with colour. That's the kind of garden success we all want, and this product helps make it happen.

For best results, mix in at planting out and filling your baskets, containers, growbags and pots indoors and outdoors.
