My carrots grow best in a bed where something else has grown the previous year. I DON'T fertilize carrots, because as soon as they find a little bit of nitrogen, they fork, and they're really hard to clean. I sprinkle the seed and press it into the wet soil. I then put some old palings on top, and don't check them for a few days.After four days or so, I check to see if they're popping up. As soon as a few of them have popped up. I lift the boards, and put them on little blocks of something, to be about 1-2 inches off the ground. This protects the small carrot plants from the sun, and helps to keep the moisture in a bit. After a week or so, they are big enough to take the boards away, and voila, they should grow pretty well. Just thin them out after a couple of months, so you have some baby carrots for salads/steaming/whatever, and the others will grow to beautiful fat vegies. Chantenay are my faves, they just seem to have a sweeter more robust taste. Don't forget to water during summer.

Previously had planted both seeds and seedlings with terrible results - roots were curved and woody - Yuk! Almost gave up. Found out my high nitrogen soil (horse manure) has a negative affect. Used old veggie boxes (thick waxed cardboard) to create a raised bed and filled with 60% landscape sand and potting mix. Planted seeds in August and have not fed them at all and the carrots are lovely 4-5 inches, straight and very sweet. Go figure!

have never planted anything before and would like to know how long it takes for carrotts and parsnips to come up?

Carrots do not like excess nitorgen. This will cause them to fork or grow stumpy. Don't fertilise with Dynamic lifter. We planted carrots and they grew very well but you do need to leave them for about 3 months to grow sufficiently. Carrots grow best from seed. If you buy seedlings and then transplant you are disturbing the roots which are the part that grows to form the carrot.

Lisa. How long have the carrots been in? Are they getting plenty of sun & water?

my carrots are VERY leafy but have tiny root growth. Good soil. Good drainage. Not too much fertiliser. What am I doing wrong???

I have the same problem it is now 8 September and I put them in about 5 months ago. Lots of green foliage. short subby carrots. The soils is deep and mostly made up of composted lawn clippings.

Many thanks for the info David, most appreciated! I've planted another crop of them but will lay off the fertiliser this time.

Dee. "You are what you eat" same for vegies, I am guessing the bad taste came from the Liquid Nitrosol rather than the basil. Carrots don't need feeding whilst they are growing, just dig a little (very little) compost in before planting and keep well watered.

Hi all. Has anyone had any problems planting carrot seedlings with basil? I'm new to vege gardening and didnt think about companion planting too much (obviously :)). They were the round variety and ended up quite small and they were so DISGUSTING I wanted to scrub my tongue with a wire brush to get the taste out of my mouth. I used liquid Nitrosol to fertilise - do you think the basil or fertliser may have been the reason for the bad taste?

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.
