About to give up with radish

Radishes are funny things, they either like you or the alternative...

I could never, ever grow the things properly, but this year, I started sowing Annabelle F1 (Unwin) in trays, on a shelf in the GH, and they have romped away!

They seem to have adjusted to the extra heat, care and watering, and have really improved my faith in human nature - for once!

The seeds are big enough to sow separately, so I pop them in at inch and a half spacing, and for the first time in about three-hundred years, have the best results I could wish for!

Have a go, the seeds aren't cheap, but at least you'll get a reliable crop - even in a sunny spot outside if you are without a GH of course!

Best of luck!

(Lucky you, North Devon too)!

Never really have any problems growing radish and not had anything ever attack them.
But I always grow mine in a greenhouse and put on the lowest shelf of a shelf unit, so they are basically on the floor.
I sow them in small tubs about 6" x 4" and 2" deep. Sow thinly about ten seeds in two rows.
I sow regularly, a new tub every fortnight and usually have about twelve tubs on the go at different stages.
I alternate the sowing between the varieties of my favourites, French Breakfast, Cherry Belle and Sparkler.
I use sieved garden soil and have just reused it year on year, with a once a year top up of sieved soil from the garden.
I have heard that adding any garden compost actually makes them fork or grow thin and tall.
Always find with radish, they dry out very quickly and like the dry conditions we have now, would be watering them daily, but as mine are in the greenhouse would be doing that anyway. I also have a tray underneath the tubs, that I fill up with water, so it drip feeds the tubs and keeps the soil moist as well.
