If the damage is to the roots (bulb) themselves, this article may find helpful: https://www.gardeningknowhow.com/edible/vegetables/cabbage/control-cabbage-maggot.htm

As for foliage damage, there are several kinds of caterpillars that feed on the leaf tops. The standard treatment for almost any caterpillar is Bacillus thuringiensis, also known as Bt. You can also try neem oil. This is usually effective on those kinds of pests, as well as many others.

Q. How Do I Prevent Worms in Growing Radishes?

You can try DE (https://www.gardeningknowhow.com/plant-problems/pests/pesticides/diatomaceous-earth-insect-control.htm) or neem oil (https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm). Both are safe for human consumption and organic. They both work well to kill larva in plants before they get too far.

Q. Harvesting Radishes

When we pick our radishes, they are nice and firm; however, when they sit for a day or two in the fridge or on the counter, they become very soft. What can I do to keep them firm?

Radishes should be stored in an open or perforated plastic bag in the refrigerator and are best if used within two weeks of harvest.

Q. What Is Up With These White Radishes?

Novice gardener here. Thought I’d try white radishes. They are now about 18″ tall and still only very thin radishes forming – hardly round at all. Just a tiny nibble. They have white flowers and have grown little pea pod looking things EVERYWHERE that smell like radishes. These are pretty much taking over the world. I figure I may as well cut them way down to force more energy into the bulb. But is this how it goes? I can’t find any info or pics of what I’ve grown.

It sounds like your radishes have bolted and the pea pod things are seed pods (you can let them just keep growing and then collect seeds for next year). You can try to cut off the flowers, but it is unlikely that it will help with forming the root better at this point.

You should pull the plants out (or leave them to collect the seeds) and try again. They will not likely grow proper roots at this time. Keep the new crop well watered and try mulching around them after they appear to help keep the roots cool. This will help stave off bolting and encourage them to grow better roots.

Thanks Heather! I didn't even know about bolting. I just read about it and now I do. Thanks.

Q. Growing Radishes

My radishes are all tops–no bottoms. Why is this happening?

Answered by

A.

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.

This can happen for many reasons. Typically with radishes, it is not enough water. Try increasing water to the plants and this should help.

Q. Root Maggots in Turnips and Radishes

Will sprinkling ashes on top of the row where I have planted turnip seeds keep the maggot flies from laying their eggs there? Will the ashes harm the plants or the soil?

Answered by

A.

I would not recommend using ashes to get rid of them as the ashes, depending upon what all is in the mix of ash, can cause soils problems that will take some time to correct. Here is a link to a great article on controlling root maggots for you:
