Why are my radishes all leaves and no bulbs

Too much nitrogen, grow some lettuce chard or cabbage there

Is it possible to grow Radish "Sparkler " in a 1.2 by 1m pot? The specific name for the radish "sparkler" is Raphanus Sativus Thank you in advance
01 May 14, Travis Edwards (Australia - temperate climate)
in simple the answer is YES. raphanus sativus is actually the name of most of the radish family that we know are edible. I plant in rows approximately 175mm apart, and try to space your seeds roughly 25 mm (1 inch) apart and about 10mm deep in the soil. you will find sparkler cherry belle long scarlet and many others also have the raphanus sativus name

Does 1 seed produce 1 radish? Or does it grow in a bush? Only 1 person will be eating them and I don't want to grow too many.

1 seed produces 1 radish. We had lots of varieties last season.

Can you eat the leaves of radish? I don't fertilise but have poor root development. Probably too much nitrogen in the compost that I forked through before planting.

A better suggestion is a Styrofoam box used for corn or zucchini - if you can find bigger boxes the better - you can grow more at a time. Go to Foodworks, IGA or any supermarket and ask if they have any. Put newspaper, shade cloth or bubble wrap on the bottom - then about 25 mm of small pebble (the beach) - then another layer of paper, shade cloth or bubble wrap with some holes in it. Mix up some soil, sand, compost/manure and potting mix/seed raising mix. Put that in the box and give a good watering. Plant the radish and sprinkle some soil/ potting mix/seed raising mix over the radish. Keep out of the sun until they germinate or put some shade cloth or something similar over them until they germinate. With this free draining soil and shallow soil depth they will need watering each day and plenty of sun. Have 2-3-4 boxes and have a succession of plantings. This method can be also used to grow lettuce and baby spinach - plant very densely and cut the young leaves about 25-50 mm up the plant and they will reshoot - multiply cuttings. You can buy seeds on the internet 100-200 seeds for $1.
