Carrot Juwarot
A variety of carrot
How to sow carrot juwarot: Direct Seed, thin to 3cm apart when seedlings are 8cm high
Sun requirement for carrot juwarot: Plant in Full Sun
Another rare carrot from the Henry Harrington Collection. It is a well known carrot overseas, however it is also a New Zealand heritage cultivar, having been grown here for at least 80 years. Juwarot was bred especially for juicing and raw eating, and is juicy crisp and sweet and has double the Beta carotene content of other carrots! 249 mg/kg highest ever recorded in carrots!
Planting Instructions: Sow seeds fairly thickly, in successive sowings during spring, summer and early autumn in warm areas.

What are growing degree days?
A plant grows with warmth, not with days. A growing degree day is one day's worth of useful warmth: how many degrees the day's average temperature is above the lowest temperature the crop grows at. Add them up from planting and you know how far along the crop is, whatever the calendar says.
Say that lowest temperature is 10°C. A day averaging 17°C gives 7 growing degree days. A day averaging 8°C gives none, as it is too cold for the crop to grow. That is why the same lettuce takes about 50 days in a summer and 90 in an autumn: it needs the same total warmth either way.
For carrot juwarot, the FAO EcoCrop database gives a lowest growing temperature of 3°C and a shortest growing cycle of 40 days at its best temperature, about 660 growing degree days to a first harvest.
Where you've told us where your garden is, we use this and the weather there to predict when your carrot juwarot will be ready to harvest. We don't use it for how long a plant lives or when it finishes: we go by what members have logged for that.
