How does Larvanem work?

The nematodes enter the pest and release symbiotic bacteria into the pest's body cavity. These bacteria convert the host tissue into a food source, on which nematodes feed, develop, and reproduce inside the host. This kills the pest within a few hours to days after infection. The Infected host turns red-brown but may be difficult to find, due to rapid degradation in the growing media.

Clover Multi-Purpose Compost is a peat-based growing medium for all plants. It is suitable for seed sowing, potting-on, containers, hanging baskets, tubs, vegetables, and bedding plants. It’s one of the most versatile composts for both home and professional gardeners.

Yes, Clover Multi-Purpose is an all-purpose compost designed for almost every type of plant. However, for lime-hating plants such as rhododendrons, camellias, and azaleas, we recommend using an ericaceous compost for best results.

Clover Multi-Purpose is peat-based, giving it superior water-holding capacity, root aeration, and consistent performance. Many gardeners prefer it over peat-free options for reliability, though we also stock peat-free alternatives if you want an eco-friendly choice.
