can carrots be transplanted and how
No. Sow them thinly and when you thin them to final spacing you can use thinnings for salad. Yum.
They can be sown in lengths of guttering, which can then be slid into a matching hollow in the soil, then proceed as above.
A variation on figrat's suggestion - I sow some of mine in 2" peat pots. As soon as they show through the soil I put them in the ground with the pots almost touching. This eliminates any very early thinning out. I then pull every second carrot when big enough to use and leave the rest in the ground to grow on. It seems to work for me.
The problem with thinning is that it can encourage carrot fly(Monty covered this in last weeks episode of GW)so I plant as thinly as possible to avoid this,no to transplanting.
I sow carrots in situ, in a 50/50 mix of sharp sand and garden soil. The carrots grow in large containers, which are approx a metre height off the ground.
thanks for replies everyone most helpful
