How to fertilize plants growing in water
I have several lovely plants growing in water only - in clear jars in a windowsill. I'm wondering how to fertilize a few that aren't doing so well. Are there any home remedies you'd recommend - i.e. diluted green tea mixed in, finely crushed egg shells in the water, epsom salts in the jar, etc.? These are all tips for fertilizing potted plants, but I need to help out those in clear glass jars without overpowering them and the water they are in and without making the jar look gross. Thanks!
