There are many ways to solve this sandy problem without going to great expense. Before You spend You hard earned $$$. Start a compost corner of Your garden. Only 'organic' matter from Your garden goes in. The seaweed, can You add this in ? If not keep all kitchen scraps, mown grass, other cuttings but do remember that 'weeds' have seeds and will invade Your efforts put them in Your bin. If there are any places where bagged horse, cow, chook poo etc are sold at road sides these will bring up Your soil Nitrogen levels as well. Spent mushroom compost has two advantages, it's perfect for You and new mushies usually grow. !! Good luck. Gregg.

Apologies for the late reply.Thank you for your advice on improving my sandy soil problem...I'm lucky enough to be able to acquire a great variety of animal manures and have started keeping all my organic matter for a that little compost corner including my kitchen scraps, seaweed,egg shells and banana skins. I have progressed to doing one half of my plot with layering all of the above with peastraw in my No Dig garden and it's coming along beautifully. As they say it's cooking!!! We get a little impatient as gardeners and expect things to happen yesterday but I'm doing all the right things so all is good. Thank you again for your imput I have really appreciated the advice. Heather.

Hi Heather. I was in a more temperate area of Tas when I started gardening in nearly pure sand. Every weekend I took the kids to the beach and we collected bags of sea grass. Spread, and when dry tilled in. After two or three years, carrots were huge, tender and flavoursome. Some could be over 600mm long and completely edible. So there are advantages in persistence. Beware sheep manure!!!! It can be full of the most obnoxious weeds. Better to hessian bag it and place in a barrel of water for two weeks or more. Dilute the 'water' in your watering can, to the colour of weak tea and use as a plant leaf spray and around the roots. Once I had built up the humus, I could grow anything.

Can you also plant them from carrot tops from carrots in the supermarket?

Yes & usually quite easily. Bear in mind though, that supermarket produce varieties are developed & adapted by industry to suit their needs & to overcome the mass production issues of farmers (who are often in other parts of the continent). They are therefore not necessarily going to be as well-suited to you as a variety that you can actually access info about, & can determine if it matches your garden's needs. That said, I often regrow things like spring onions from the supermarket too, rather than throw them away, as that seems quite wasteful to me too.

Of course you can! You won't get a carrot root but keeping it in a tray of water will let it develop a flower stalk from which you can collect seed true to type. Why would you throw away free seed? Same applies to celery and beetroot!!!

Growing carrots from the tops leftover after cooking the roots will get you a lovely plant from which, if placed in a tray of water, a flowerhead and resulting seeds.Collect them to grow on all year round!

I have grown carrots successfully for years, using either purchased seed, or some I have saved myself. I usually plant just after the shortest day of the year and find that they will stay in the ground, growing happily for a year (or just over). This year however, they all seem to have bolted to seed. I used saved seed, and planted just two days before the shortest day - didn't check the calendar properly. I can't work out why this has happened. Can anyone help with an answer?

There were a few days of very hot weather in October which has made my uncovered carrots go straight to seed but the ones growing with some cover and next to a water tank (cool thermal source) are forming nice roots, no flower heads on any of them. Secret to successfull carrot growing? Grandad said always plant your root crops 14 days apart all year round, that way you avoid famine/feast issues and you have a rolling crop of baby/mature carrots with only some going to flower.

Always grow your carrots in loose well dug soil..great after broccoli, leafy greens, cabbage, sprouts etc.(heavy nitrogen users) do not fertilise carrots!! High nitrogen in the soil will cause the carrot to fork and twist etc, as mentioned by others here. Also do not over water carrots.

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.
