Can pesticide spraying and fertilizing be done at the same time?

1. Can it be done at the same time?

If you want to fertilize the roots when growing flowers, you can do it together with spraying pesticides, because the roots will absorb some nutrients. Water-soluble fertilizers can be directly applied to the roots, and the roots will absorb them themselves. The spray is sprayed on the leaves, so the two are not in conflict and can play their respective roles. However, it is not recommended to carry out the two operations at the same time, because they are both chemical agents, and it is not known whether there will be conflicts with each other or adverse consequences. Especially for foliar fertilization, it is best not to use the two together on the leaves to prevent affecting the growth of the plant itself.

2. Correct Method

In order to fully exert the effect, the two aspects can be separated by a few days. If the pests and diseases are serious, you can apply pesticides first to remove the pests and diseases, and then wait for a few days for the effect to evaporate before applying fertilizer, so that the fertilizer effect can be fully exerted. There are also some flowers that are suitable for both treatments at the same time, such as roses, which can be done at the same time, and foliar fertilizer can be added while spraying pesticides. However, please note that bactericidal copper pesticides and calcium-containing foliar fertilizers cannot be mixed.
