Cover with board? I don’t understand how a plant grows when it’s covered with a board? I must be missing something.

Cover the planted SEEDS with a board until they germinate to maintain a moist soil. Uncovered soil dries quickly (which is why we use mulch to cover them as well). Seeds will not sprout when stressed by dry soil. You barely cover the carrot seeds with soil since they are so small. Good luck!

It's mostly to help with moisture. Carrot seeds cannot be allowed to dry out. They come up from under just fine.

A board such as a 1 X 3" is simply to keep rain from dislodging the tiny seed from the soil and retain moisture. I check my seed germination after a week then daily until the seedlings are about 1". Then I remove the board, thin the seedlings and cover with a floating row cover. I plant them right next onions and have no problem with flies.

You only cover with a board temporarily as to keep the seeds from washing away and from birds eating them. After a week or more, You are to begin checking for sprouts. Within a week to 10 days, if it’s getting hotter in your climate, you elevate the board above the sprouts by placing a rock at each end of the board length and place the board on top of the two rocks. This keeps it a bit shaded since carrots are cool weather. Then as they get larger ferns and safer to expose, you remove the board. I hope that’s helpful.

Thank you. Your explanation was clear and much appreciated.

Use shade cloth or hessian bags above the soil.

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.

Will it be too late to sow these in early September?

Carrots: -- Germination minimum temp is 2c: optimum germination temp is 10c to 25c (the temperatures must be sustained). Seeds germinate over a 2-week period -- if crust forms on the top of the soil, germination will be restricted. *********** Optimum growing temps : 15C to 20C , with a minimum of 5C and a maximum of 24C Outside of the growing range (less than 5c or more than 24c) the carrot goes into "dormancy/holding pattern" with extreme temps killing the carrot. ********* Average days to harvest for carrots is 60 to 80 days. The days to harvest are calculated based on ideal growing conditions (temperatures/sunshine/water). *************** Having lived in your area MANY years ago – I can recall – and checked with environment Canada – Based on last year’s temp – June was a good month to start planting carrots – and September had decent carrot growing temps – as did the first week of October. I would plant carrots in semi-shade as Stoney Creek can get VERY HOT in mid-summer – and this is a problem for carrots that don’t like temps over 24c. ********* So, what I see is a total of 129 days of good carrot growing weather (June 01 – to the first week in October). You need 2 weeks for germination and depending on the type of carrot about 80 days to harvest: total of 94 days. If you plant starting June 01 – you can plant carrots every couple of weeks until around July 5th (07/05 plus 95 days yields a date in the first week in October). If you want to do only 2 plantings – then I would plant on June 01, and again the last week of June. This is based on 80 days to harvest – if you have carrots with a higher number of days to germination and/or days to harvest (like dragon carrots that take 90 days) – adjust accordingly. You need your last harvest in by the first week in October so count backward to find your last planting date. Bolero Nantes have the following stats: Germination 10 - 20 days and days to harvest 70. The site indicates that your last planting should be 3 months before your first expected frost date -- and it looks like your first expected frost date is October 15 -- which yields a last planting date of: July 15th which is a couple of weeks later than what I have calculated .... remember that Nobody can guarantee what your weather will be ..... when it comes to your last planting, I would error to the side of planting a little early -- and I would feel a little bit short on time with a July 15th planting...but I have heard of people planting later and doing just fine.
