I started the seeds in January and planted all my veggies in something I learned a long time ago .I use course sand loam and pasturized manure and peat .Keeps the veggies cleaner and just add liquid growth food .Great for things like lettuce ,carrots,radishes,potato's ,and any kind of fast growing veggie .I have even planted my straberris in it and they are alreay out of the ground and I can see the flower buds on a couple .Great for blueberries ,raspberries and grapes also .It allows the fertilizer to get down where the plants need it more .Boy will you get a crop of potato's .
