Why are my radish and beet roots extremely long and the radish and beets small?
This happens when the ground is too heavy and too weak in phosphorus. These articles will help you:

What is the most suitable product in a commercial fertilizer for the best results for onions, beets, and radishes?
A phosphorus rich fertilizer will help with growing larger onions, beets, and radishes.
Every year I look forward to planting my radishes in the hopes that I will get some. Not so; every year I get lots of green but no radish. They don't swell. I keep them watered and free of weeds, etc. Thin them and even go out and talk to them. No luck. Mixed the soil with rotted manure and some peat moss (regular soil is heavy clay) and still nothing. Why?
This is normally caused by too much nitrogen in the soil and not enough phosphorus. You may not be able to salvage this batch, but in the future, add bone meal to the soil when planting root vegetables.
What is the best way to store radishes?
Radishes can be stored in the refrigerator but are best used within two weeks of harvesting.
I over fertilized my radish bed and have tiny radish roots with large gorgeous flowers. What to I do to get the large tasty radishes? How do I un-fertilize?
You can flood the area with water to dilute any remaining fertilizer in the soil and then add some phosphorus, like bone meal. This will help the plant produce more root (radish) growth.
I usually plant my radish seeds by preparing the bed by raking a small plot smooth, scatter the seeds by hand, spread the dirt over the seed by rake, and firm the soil by tamping with the rake. This works fairly good with about half the plants developing into nice size radishes, but the other half develop long roots without bulbs. This year I planted them in a row in a depth of approximately one-half inch. Nearly all just developed elongated roots. What am I doing wrong?

What can I do? There are small holes chewed in radish leaves. Radish is not rotten inside, but some insect is having lunch in my garden.
It is likely slugs or snails. They feed at night and will leave holes in the leaves and little trace of their visit other than that. This article will help:
