When using Fertilizing applications for weed control its all about the timing.
- The first application of the year, if it has pre-emergent weed control products in it, can’t be done too early in the season.
If it is applied too early in the season, your Harford County lawn can have mid-season crabgrass break through. - When pre and/or post emergent weed control products are applied, it is important to make sure that there is not new grass seed germinating. A good rule of thumb is to wait until the new grass seedlings have been cut 3 times.
- When applying pre-emergent weed control products, it should be done before it rains. This allows the product to be watered in.
- When applying dry post emergent weed control products, the grass should be wet to allow the product to stick to the weeds better. Then it shouldn’t rain for approximately 3 days to allow the product to stay on the weed leaf.
- Post emergent products shouldn’t be applied too early in the season. Some weeds germinate later than others and this would require another application of post emergent products.
