Hello, This year im going to try a couple of small plots with 5-7 plants at two different areas. I found an unopened bucket of: Plant Prod-All Purpose Fertilizer (20-20-20). On the box it says is is a "concentrated water soluble fertilizer with micronutrients. I know im supposed to only do 1/4th or 1/3rd of the recommended fertilizer per litre of water, but how often should i water the plants using these fertilizers? And how often with just regular water? I will be growing in Kamloops, British Columbia, so it's quite dry, and the ground has some clay in it. Would i need to mix potting soil in with some of the regular dirt thats already there? Whats the best brand and how much will it cost? Will classic old miracle grow work? Also, how big should each hole be? I am planning to start them on cups right outside my house, then once they are big enough, i will plant them in the soil at my grow spot. Also, since im slightly low on money at the moment. are there any other fertilizers that are absolutely needed for the succesful growth of the plant? I read online that the last frost in Kamloops is around May 1rst, so how far after that should i start my seeds in cups?
