You're mention of carrots prompted me to post. Doing the shopping in Sainsbury's on Thursday, I bought a pack of Chantenay carrots for all of 90p. ($1.14) Vegetables are relatively cheap compared to other foods in this country.
When we bought this house, half of our small garden was a vegetable plot. In the corner where our tea-house now sits, was an old cedar greenhouse.
We had some success with runner beans and potatoes, but little else in the veg plot. Tomatoes, peppers and cucumbers grew well in the greenhouse.
Our house is built on the aluvial plain of the river Mersey and on the site of a former farm. The soil is free from stones and a bit sandy, so probably ideal for growing some varieties of veg, particularly carrots, but I never bothered. We had young kids, so we got rid of the veg. plot and when the kids left home, the greenhouse.
I was never into veg. gardening. It was a bit of a chore. I'm all for "low maintenance," when it comes to gardening, if there ever is such a thing. I've so many other hobbies I enjoy.
