Back in April, I sowed eleven triplets of Sweet Candle Carrot seeds in a vermicompost layer atop 17 litres of Multipurpose Compost containing some friendly bacteria, fungi, rock dust and a smidgen of Nutrimate in a Polypot bag, which I usually use to grow show potatoes.
I did a post about how well the seeds had germinated after about 3 weeks and then I thinned each station to one plant.
Over the summer, the polypots lived on a plastic tray in our front garden. After letting the roots develop for 6 weeks through minimal watering, I started to fill the plastic tray regularly with water, allowing the roots to swell through absorbing moisture from below.
I also fed the roots twice with comfrey tea on root days, once in July and once in August.
I harvested the first polypot on Saturday 9th September, the morning of the village show. The feature image shows the eleven roots, which weighed in at 7.5lbs.
The largest two roots had cracked, making them unshowable, so they and the smallest root were turned into carrot and coriander soup.
The other eight formed two groups of four to exhibit, winning a first prize for carrots and a second prize as part of the four vegetables class:
Given that one pot only occupies between one tenth and one twentieth of a square metre, you could in theory grow 75-150lbs of carrots on an area of just one square metre!!
For those limited in space to garden, this may be a valuable option in freeing up space for other vegetables best grown in soil.
