A fertiliser low in N, too much N and you end up growing a lot of leaf. A good idea is to put your fertiliser in the soil a week or so before planting and mix it in/over a few times and watering it each time, this allows the micro- organisms in the soil to convert it into usable nutrient. Check the N P K of the fert. Some organics are real low say 1.8%N, rooster booster is about 4%N. A handful or two of that spread over a square metre. All depends what the soil was like before you started.

Carrots, learn how to use this website please, the info is there. Best protection is to cover them with a fine netting. Check for grubs every day. Read about organic sprays or go and buy chemical sprays.

I often plant carrot seeds in Adelaide and they are always successful. I need to plant more but wondered if it was advisable to plant just before a heatwave? Tomorrow is forecast 31, tuesday 34 and wed is 40. Thanks jenny

Anything planted in hot to extremely hot needs protection from the sun/heat. Very small seeds are planted very shallow. With hot temps the top few mm of soil dries out very quickly. Very hard to germinate when the soil is very hot/dry some of the day then wet from watering. Try to keep the soil temp as constant as possible and moist. I use a 1.8mx1.8mx.5m high wood frame with shade cloth on it. I have 30%, 70% and 90% shade cloth.

How long should you leave the board on? Most of my seeds have germinated but are becoming leggy to search for light. Thanks.

If they have germinated then they will be ready for the board to come off. The board is used simply to keep the heat and moisture in the ground to help them germinate.

Germinating carrots - don't have too rich a soil - have a nice crumbly fine soil - even sandy loan. Rake it real flat. Dig a little furrow about 5-8 mm deep. Put some carrot seeds in your left hand and pick up a few with your right hand and spread them along the furrow thinly. Gently cover the seeds with some light soil or very fine seed raising mixture and then give a light patting down on the soil. Give the seeds a gentle watering. Build a little frame over them with things like tomato stakes on bricks etc.Then place some 30-50-70% shade cloth on the frame. Give the seeds a light watering morning and afternoon. A few days after germination take the shade cloth off. You can apply the shade cloth idea to germinating a lot of different seeds if the weather is warm to hot. If planting big seeds like corn beans peas - plant the seeds then give a good watering and then don't water for 3-4 days - then a light watering each second day. Too much water they will go rotten..

Take the board (????) off a few days after germination. A good way to protect further is to use a shade cloth device - about 30-50% shade cloth.

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.
