From bindweed to dandelions and thistles, weeds are the bane of every gardener’s existence. As the old joke goes, the best time to deal with them was yesterday, and the second best time is right now—so the quicker you tackle them, the better. But before you buy, it’s worth bearing in mind a few important points.

If you’re dealing with a small area of weeds, you might find a bottle with a trigger spray is adequate. However, for larger areas, it’s worth taking the time to think about how you’ll distribute the weed killer. Some formulas come in large plastic jerry cans with an integrated pump and spray, but for others, you may have to buy a spreader separately.

Look at the ingredients and consider what you want in your weedkiller. Some contain compounds that are suspected of harming marine and aquatic life when they drain into the water system, or are used near ponds. However, more natural alternatives are available so it’s worth doing your research before splashing your cash.
