Carrot fly seems to be getting rampant, you can buy resistant seed. One way to prevent them is to spray with diesel/kerosene which not only deters flies but kills weeds! The only sure way is to buy some biomesh insect screen and put it over the carrots as soon as you sow them. Make sure there are no gaps at the bottom though as the fly operate at about ground level.

Hi Max, I have been growing carrots in large black plastic pots and have had no trouble with any bugs or nasty things. I sow the seed one by one in separate holes and in a circle around the pot, cover with some sacking and then lay a couple of largish stones to hold the sacking down till they sprout and then uncover them. I hope this helps. Joss Roberts

If you transplant them - cover them with shade cloth or something similar for the first week.

It really comes down to what kind of carrots you would like to grow and eat. Long, thin, short, fat, orange, purple etc. Depending on your weather maybe better to wait until cools a bit. From the notes it likes cool soil - like 40 degree days in summer will nearly fry them.

If covered with agribon frost cover or pv now (Dec. 1), could I sow carrots ? We have had 2 frosts?

I suggest you go by the planting guide for your climate zone.

Cover with a board means: place a board on the ground flat over the seeds. Carrot seeds do not need light to germinate. Look under board a couple times a day if possible, until you see first leaves of carrots. When more than 10 % or so appear, remove the board so they can grow normally. PS it works well to plant not a single ROW of carrots, but a band of carrots, maybe 6 to 10 inches wide. Whatever width you can manage to work. To thin. If sown thicket enough, you can pull the little babies to thin and use them in salads.when you have carrots left about 2” apart, leave them to grow to size. As you need carrots, thin further. By the time they mature you should have enough room for them to grow full since. You might leave 2 or 3 in a back corner to continue on to next year, when they should eventually go to seed for you. To save seed, allow them to die and brown, save the tops and further dry seed indoors on an herb rack of mesh that should prevent seeds from coming through. When dry, collect on a piece of paper and allow to dry further. When dry, store in a paper envelope or seed pack.
