Are Radishes easy to grow?
Yes. If they are grown in good conditions and you like watering.
I used to grow Radishes with my kids, because they only take 3-10 days to germinate.
Some years growing radishes it's a "hit and miss" for me as well. I get a lot of leaves and a few bulbs. I guess it gets too hot in the spring. I have better luck with a fall crop.

Harvesting:

Only 25 - 30 days

Why do Radishes Bolt?

With me it's mostly the heat.
As soon as it gets hot, Radishes will go to seed. You can eat the tender seedpods or use them in salads. They're tasty treats when I go to the garden. They rarely make it to the house. I also dry and save the seedpods for next year's seeds.

Why is my Radishes roots/bulbs hard?

I find if the Radishes are over grown, they will be woody or if they don't get enough water.

What can you interplant with Radishes?

I sow carrots with Radishes, because the Radishes will be ready to harvest in 25- 30 days.
Carrots takes forever to germinate like - 15 - 20- days.
Onions and Parsnips with Radishes as well.
