2017 was a year experimenting with growing carrots in 17 litre polypot bags.
Back in September I harvested Sweet Candle carrots sown for show, with 11 roots weighing 7.5lbs.
The second experiment concerned sowing carrots late (at a time later than normal garlic harvest). The date chosen was 30th June 2017.
Seeds were sown at a higher denisty than the Sweet Candle bags as it was unclear what sort of yield would emerge.
The results of harvesting the first bag on 7th February 2018 were excellent, as shown in the feature image.
32 roots were harvested:
4 large roots weighing a combined 2.2lb;
14 medium roots weighing a combined 2.5lb;
14 small roots weighing a combined 1.0lb.
A total yield of 5.7lb was achieved, suggesting further optimisation of sowing density and date is worthwhile.
Whilst there is minor damage to around eight roots from carrot fly, the quality is more than good enough for home use.
The conclusion to be drawn is that six months worth of autumn/winter carrots can be grown in six bags through two sowings in late March/early April and late June/early July.
This represents no more than 1 square metre of space required on a patio and the issues of slugs eating young seedlings can be largely eradicated.
