If you have only a few plants that need to be fertilized regularly, it can be a pain to do it, and it is something that we often end up putting off because of the time and mess doing it, even though the results are worth it.
Next time you need to fertilize the plants, take the time to measure out the right amount of fertilizer and put it into ziploc bags sealed tight to keep the moisture out, then write the instructions on the outside of the bag. Then next time you need to go and fertilize the tomatoes (or whichever plant needs it) you simply grab the baggie and add the appropriate amount of water, saving you the time needed to bring it out, measure it correctly, etc.
This trick will definitely make your future fertilizing jobs quick and painless.
