Brussels Sprouts
How to sow brussels sprouts: Sow seeds indoors, harden off seedlings before transplanting outdoors
Sun requirement for brussels sprouts: Plant in Full Sun
Brussels sprouts grow on the sides of stalks up to 91cm tall. The stalks are covered with leaves and the sprouts look like miniature cabbages. They are a cool weather crop and are delicious roasted.
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 brussels sprouts, the FAO EcoCrop database gives a lowest growing temperature of 7°C and a shortest growing cycle of 100 days at its best temperature, about 900 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 brussels sprouts 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.

What's better than Brussel sprouts? Home-grown Brussels Sprouts grown by robots.
The automation (aka Robots) I'm using is an open source app called "Home Assistant". It runs nicely on a raspberry pi, but I'm running it on an old laptop, which is ve…
