We are all friends on here I'd like to believe, I'd like to take my hat off to you but I don't wear a hat lol. Getting back on to the subject of plants, I'm no expert in plants but I have also learned a lot from the many good people on here. I was speaking with my friend today who had there Lemon tree die after he had giving it citrus feed a while ago and I've also had similar experiences in the past with plants going down hill once they have had either fertilizer or general plant feed. I've learned from my experiences so I always just leave plants to there devices and I only use natural things like compost or dead leafs from trees to line plant pots with. Oak leafs I've found are a good way off feeding a plant, however all plants are very different that require different kinds of feed. Most indoor plants don't need such feeding. One thing that I've always wondered is how much watering should various plants get as there are sometimes issues with over watering or under watering.
