How to sow carrot: Direct Seed, thin to 3cm apart when seedlings are 8cm high
Sun requirement for carrot: Plant in Full Sun
The carrot is a root vegetable. It is usually orange in color, but some cultivars are purple, black, red, white, and yellow. The most commonly eaten part of the plant is the taproot, but the greens are sometimes eaten as well. The leaves appear first, and the taproot grows more slowly beneath the soil. Fast-growing cultivars mature within three months of sowing the seed. Slower-maturing cultivars are harvested four months after sowing.
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, 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 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.
Only plantings by members who have set their locations are shown.

I'm going to attempt to grow potato over winter. To prepare I'm going to do a full garden bed of mustard and then dig the greens into the soil. Add compost and blood and bone. I've never attempted potato over winter. It can get very wet here, and in …

I like to automate the calculations, analysis, and plain old remembering what has happened in the garden.
Some of the challenges in my garden is knowing when it's too late to planting something, if it will cope with the weather conditions here, and working out what is killing the [tomato](/…

Do carrot transplant well at all when they are small? I set up some rows of carrot seeds mixed with radish seeds, but I don't know if the carrots will be amenable to transplanting once they sprout. Has anyone done this?

My raspberry are flowering!
Anyone whose english pea plants yield spherical peas must be a saint. I only get spherical peas if I miss a pod. In the evening I sit out in the garden and eat peas until there is nothing worth eating left on the plant. Then I am done…

I had the first tiny strawberry of the season today! I'm looking forward to many more.
Also, I transplanted a lot of seedlings into the community garden today: 2 cucumbers, 3 green beans, 2 tongue-of-fire beans, an ornamental [sweet potato](/crops/swee…

Something's skeletonizing my carrots and dill. It did a number on the sweet basil I planted, and is taking out the kale plants one by one. I haven't caught it in the act yet, though I've seen a couple big fat grasshoppers around; they're pretty lik…
