It’s extremely powerful so be sure to use it with caution and experiment with the lowest measurement first: use 1 to 2 grams per litre of water per square metre of lawn and apply with a sprayer for better coverage. Pre-emergent herbicides work by preventing the weed from growing in the first place, so you shouldn’t see weeds popping up after using this type of product. When To Water After Applying Weed and Feed Fertilizer Application? Regardless of the type of weed or grass, applying weed and feed during the winter will have absolutely no effect on the appearance of your lawn in the following spring and summer. Hence, weed and feed is most effective when applied in the spring and fall.

That way, you can apply lawn feed + weed killer twice a year, but keep the grass topped up with lawn feed the rest of the time. Choosing Liquid or Granular FormulasNaturally, you can’t apply lawn weed and feed during the winter. When the temperatures are below zero weedings and feeding isn’t recommended, because the soil is too hard and can’t absorb the nutrients. Summer is also a not good idea for weeding and feeding because the soil can be too dry for absorbing the nutrients. However, there are some exceptions, for instance with Scotts weed and feed schedule. Safety Considerations Granular: If you have a large lawn, then granular weed and feeds are a better option. You load the spreader with the fertilizer and criss-cross the lawn until you’re done. There’s less risk of spillage or stains with granular fertilizers. GreenView is an excellent example of this type. It doesn’t require diluting or mixing with water which makes it less messy. This is the recommended type for lawns larger than a quarter acre but less than one acre. There are other liquid products that require a more elaborate way of mixing the concentrated material with water before you can apply. We didn’t review these products since they’re a lot of hassle and can be messy to mix and apply. How many Weed and Feed applications do I need?
