Spruce Weed & Grass Killer being used in the garden

Rain can be a blessing for your garden, but when it comes to weed control, it's a bit of a wildcard. You might be wondering: should you apply Spruce weed and grass killer before or after rain? The answer is simple: why wash away your hard work? For best results, apply Spruce when sunny and temperature is above 60 degrees F. Spray the entire weed, including leaves and stems, until all visible parts are thoroughly wet. Reapply as needed. Spruce starts working on contract, so rain showers won't compromise its effectiveness.

Why Timing Matters

Spruce weed killer works by dehydrating the weeds to death, delivering fast, visible results. But for it to work its magic, Spruce is a contact herbicide and starts going to work once it makes contact with the weed. And since it works by dehydration, it is most effective on a warm, sunny day. A cloudy or rainy day may make your efforts less effective. That's why timing is key.

How Much Rain Is Too Much?

A drizzle is manageable, but heavy rain can complicate things. If your area is expecting a downpour, hold off on applying until the weather clears.

By timing your application around the weather, you'll maximize its effectiveness and keep your yard looking great.
