The fad racing across The UK is a polyethelyne fiber bag for growing flowers, potatoes, and herbs. As with the Yankee intuition and insane curiosity I manifest at times. Instead of paying $12.99 and trying to figure out shipping charges an electric zap hits me. The same recycled plastic fiber is used in green shopping bags. Having a few laying around the house, I got to work… Some dirt, moss, seed potatoes and the bags clocking in about a whole dollar per planted bag. I suddenly saw green in blue. Walmart bags at 50 cents each, add Mel’s mix, and seed potatoes at $2 for 6, frugallity hit reality. I could actually do this.
I just had a layer of dirt about 2 inches deep which I placed the potato on, and covered with about 3 inches of sawdust, adding about 3 inches of sawdust as the potato leaves poked thru.
Not only did I get a massive crop, but also, digging them was easy, and potatoes came out almost clean enough to cook.
And, a neighbor asked us to haul away some old leaves that were already bagged for a couple of years. Instant compost. I am so psyched to have my potato growing problem solved so cheaply and easily!! Wahoo!
Okay, that was overdoing it; the little things make me happy!
The advantage to growing plants in bags, containers, buckets, etc., is that if you don't have good soil - or any soil at all - you can control the nutrients, moisture level and weeds very easily. The containers are portable so if you find your plants need more or less sun you can move things around as needed.
