There are plenty of vegan fertilizer products on the market, but please don't focus on spikes, a poor delivery system for fertilizer.

You will need to apply a lot of product in order provide your container plants with what they need in order to survive. Your nitrogen source will probably come from soybean meal.

Maybe we could go back a step and verify that fertiliser is the real problem? If you could post some pictures people can see if that is really what is amiss. It could be something else and fertiliser may even make the trouble worse.

We'd also like to know what kind of potting medium that you're using. Please know that container grown plants rely solely upon us for essential nutrients. 'Essential' means that without those elements, plants can't survive.

Thank you for your responses. I am growing Basil, Rosemary, Mint and Curry leaves. I am in DC. So currently they are all indoors. Have kept them in the kitchen where they get Sunlight till late afternoon. I have used some basic potting soil, not the enriched kind I used for veggies during the spring. The leaves are starting to dry out. Not sure if it is weather/indoor heat related or if I need to fertilize them. I am especially concerned about the basil and the curry leaves.

Thank you Once again

Kurt
