I only grow baby carrot types in pots these days.
Would say its a bit late now for mine. I sown mine in April/May and will stay in the pots till late winter for picking.
Have in the past grown some like this in pots as late as July and they have done fine for a winter picking.
Have just planted out a load of Chard, Spinach, Russian Kale and Nero di Toscana.
Normally do this about now, and the Kale and Chard will give plenty of pickings through Autumn and Winter and the Spinach through till next Spring/ Summer and beyond.
By the way, have never had any problems with any from of attack on my Kale that I have planted over the years. Did used to grow the Curly types, but last few years just the ones I mentioned above.
All my Kale, Chard and Spinach has been slug/snail and Cabbage White caterpillar free in decades of growing with no covering in many parts of the garden.
Do not use any kind of chemicals on them either.
I use the fake butterfly method that was mentioned on here many years back. and since then have had great success. It was mostly for my Brussels Sprouts that got attacked and they have been caterpillar free since.
