Alright so I have a problem, the only available fertilizer I have right now is a 50 pound bag of Vertagrow for farm, lawns, and gardens. Now under the directions on the back for flowers it says use 1 pound per 100 sq ft every six weeks. All I'm growing is one plant in about a 1 square foot amount of space so I'm trying to figure out how to calculate how much I should give my plant but I don't know how and also it's almost time for my plants to be fed. Also what's the best way to apply granular fertilizer to a plant that needs food within the next week? Any help will do please.
