February is the ‘sweet spot’ of the year when it comes to applying pre-emergent herbicide to your lawn. A little effort now can greatly reduce the weed pressure in your yard later in the season. Pre-emergents work by drying up weed seeds so they never get a chance to sprout. The trick is, you have to apply the pre-emergent before the seeds begin to germinate. And that means, you have to do a little yard work before it is warm enough outside for you to really feel like doing yard work.
We have several pre-emergent options at Gaddy’s. If you want an organic pre-emergent, we sell corn gluten meal. Besides being a desiccant, corn gluten is a natural source of nitrogen, the element that helps ‘green-up’ your grass once it starts growing. Our Fertilome-Hi Yield Grass and Weed Preventer is an economical chemical pre-emergent. One $15.99 bag will cover 3,500 to 5,000 sq ft. If you want a product with a pre-emergent and a post-emergent, we sell Weed Beater Complete.
Use a broadcast spreader to apply pre-emergent granules. Read the directions carefully. Most pre-emergents need a little bit of moisture to become active. For example the Hi Yield product recommends about 1/2 inch or rainfall or irrigation. But too much rainfall immediately after application can lessen the effectiveness of the pre-emergent by washing it away.
When using pre-emergent, think about places in your yard where you want seeds to germinate and avoid those areas. Don’t apply pre-emergent in a vegetable bed where you want to start seeds next month or in an area of your yard that you want to reseed. Some pre-emergent can be effective for up to 3 months. The pre-emergent will not differentiate between the seeds you want to grow and those you want to kill.
