I grow carrots really successfully every year, twice a year. We don't have Carrot Fly in Australia, as far as I know.Carrots fork a lot when grown in freshly manured or fertilised soil. I grow them about 15 cm apart, the rows that is. I water the soil after raking it even. Then sow the carrots, and then put old fence palings over them and press them down a bit to get the seeds in contact with the soil. If it's sunny, I water the boards lightly every day for a few days, just to keep them moist. This is the trick to germinating the seeds. After a few days, between four and seven, Icheck by lifting up a board. If you see little green shoots that look like new grass, in the area you sowed the seeds, then you have germinated. I then lift the boards up about two inches or so, and put little bits of something under the boards at the ends to keep them there foe a few more days, to protect the new carrots from excess heat. After that, I just take the boards away, and I seem to get very good germination with this method. Carrots don't have a hard growing tip, so if they have to struggle growing down, they will twist and get weird shapes. Parsnips DO have a very strong growing tip, so I plant them together to get the soil opened up for the carrots. Hope this helps. Cheers.

That trick with the parsnips is clever.

on this site it says to avoid sowing carrots and parsnips together?

I suspect you would plant parsnips at the start of the season, then sows carrots once the parsnips are done. giving you 2 crops from the same piece of soil, pulling the parsnips would make turning the soil easier before planting the carrots. (Unless this is considered a no-no as well?)

Our group looks after the vegetable garden for our company - a disability service. We manage to grow successfully, - lettuce, shallots, silver beet, spinach, tomatoes and cucumbers. However our carrots fail dismally - they are short and stumpy and grossly misshapen. Can you suggest what is wrong?

Possibly because your soil is to hard I've heard that if they can't grow down they come out looking like short stubby midgets

It sounds very much like too much fertiliser, also carrots prefer open type soils if you have heavy clay soils add about a good handful of gypsum or hydrated lime (same stuff) per square meter and hopefully you should see and grow better carrots

I'm interested in the answer to this, too. I get exactly the same problem!

Carrots prefer light, sandy soil, mulched to keep cool and moist. Light soils give them a chance to grow long roots. If your soil is heavy clay, it is best to grow stump-rooted or chantenay types. A raised bed might be the answer.

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.
