There's so much baking going on here, stuck at home under the nationwide pandemic lockdown – and when we can get eggs we end up with many eggshells. These can be crushed and placed around the base of brassica like cabbage and broccoli. Snails and slugs do…

How to sow broccoli: Sow seeds indoors and transplant outside
Sun requirement for broccoli: Plant in Full Sun
Broccoli has large flower heads known as "crowns" that are green to blue-green in color, grouped tightly together atop a thick stem, and surrounded by leaves. Broccoli resembles cauliflower, a different cultivar in its species. It thrives in cool weather.

flower harvested 27 timesWhat 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.
Broccoli needs about 0 growing degree days.
For broccoli, the FAO EcoCrop database gives a lowest growing temperature of 5°C and a shortest growing cycle of 60 days at its best temperature, about 750 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 broccoli 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.

The nets are up
by shiny,
Due to the pandemic lockdown, I can't go to the hardware store to get things. I've been in semi-isolation since the start of march, and we've been in nationwide lockdown since last week.
I needed to set up the nets to keep out the white butterfly. I've had to be creative and i…

Summer broccoli doesn't work
by shiny,
I planted some broccoli at the start of spring.. I grew fast, made long stems and quickly turned into yellow flowers. I conclude the first spring summer months aren't good for brocoli.
So I've got some new seedlings in now, in the heat of summer, hoping that by the tim…

Some of features id like
by shiny,
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](/…

Transplant day!
by inkstone,
I originally wanted to do this yesterday but it rained in the morning so that kinda put a damper on things.
So I did it all today instead! A bunch of the seeds I wintersowed in the milk jugs and soda bottles were getting crowded so it was time to move them to their bigger (permanent) containers….
