2,4-D is a popular herbicide used to control weeds in lawns and gardens. It is often mixed with nitrogen fertilizer to provide both weed control and plant nutrition in one application. However, while 2,4-D and nitrogen can be applied together without problems, there are a few things you should keep in mind.
First, the timing of the two products should be coordinated so that the 2,4-D has time to work on the weeds before the nitrogen is applied. This usually means applying the 2,4-D first and then waiting a few days before applying the fertilizer.
Second, you need to be careful about how much of each product you use. Applying too much 2,4-D can damage your plants, while too much nitrogen can cause excessive growth or burn your plants. Be sure to follow the directions on the labels carefully.
Finally, keep in mind that mixing 2,4-D with other chemicals can sometimes cause problems. If you are using any other pesticides or herbicides in your garden, check with an expert before adding 2,4-D to make sure it will not create any harmful chemical reactions.
