Yes we are using gutters to grow Strawberries!
I was so intrigued when I saw Mavis from http://www.onehundreddollarsamonth.com/ growing her Strawberries in gutters in a Greenhouse!
We installed a few brackets, placed the galvanized gutters on top of them at a bit of an angle for drainage..we put two gutters in, one on each side of the greenhouse, both are 10 feet long, 5 in deep…we decided to experiment with both of them, so one is a straight soil mix…the other has pebbles at the bottom topped with landscape fabric then soil..
They were filled with the same mixture of potting soil used for my pots, equal parts of garden soil, organic seasoil (compost), vermiculite or pearlite, and peat moss. I also added an organic granular fertilizer ( recipe to follow) and lime…
We put in our plants , a combination of Everbearing and June bearing Strawberries
and placed them on the brackets..
Berries are forming already….
Here are the varieties that we have planted…
Everbearing/day-neutral: Seascape & Quinault
June Bearing: Rainier & Shuksan
