Our price comparisons cover sprays rather than concentrates, which are likely to be ideal for most home owners. If you are unsure on what to buy, please convsider supporting your local plant nursery (or garden centre if you don't have a local nursery). We recommend nurseries over garden centre's because nurseries are usually better for purchasing plants in your area. This is because the plant will have been brought up in similar soil to your own, so it is more likely to survive and flourish. Nurseries are excellent sources of information on gardening.
