    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.

    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.

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

    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.

    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.

    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:
