I have small white worms in my turnips and radishes. How do I deal with this problem?

Root maggots overwinter in soil as larvae. Root maggots are the immature stage, or larvae of small flies that belong to the Insect Order Diptera (Flies) and the family Anthomyiidae. In spring larvae move near the soil surface where they pupate. In late spring adult flies can be observed in mating groups close to borders of fields, telephone poles, or tree trunks. Females deposit eggs in soil crevices near the base of plants. Larvae hatch and feed on roots. A couple of suggestions.
Crop rotation—Plant this year’s root maggot host plants in ground that did not have host plants in the previous year. Crop rotation is often difficult in the home garden but even a modest rotation and separation should be somewhat helpful.
Dust plants with diatomaceous earth. Rove beetles are predaceous on root maggots.
Treat with a registered insecticide.
For radishes: Apply a registered insecticide in seed furrow at planting.

- I would like to plant some fruit and nut bearing trees to assist us with our food supply. Are there some trees better than others?
- I have a huge weeping willow in my front yard. My next door neighbor swears the root system has invaded her septic line. She had a globe will previously taken out that was about 10 feet from her main water line while my weeper is about 30. My own line is about 15 feet from the weeper. Is there any validation to her statement?
- Our home was built in 1998 and we are the second owners. The first owners landscaped the yard, but didn't consider that the trees, shrubs, etc. would grow. We have trees that were planted too close to the sidewalk and shrubs that were planted too close to the house. They are beautiful, but too close. We also have a large cottonwood tree in the backyard that provides good shade, but its root are now pushing above the ground. I think I know the answer, but is there a good way to redo the landscaping without removing all of the good features at once?

- My petunias are horribly sticky - I assume thrips are in control although I have tried to keep them washed off (insecticidal soap) and sprayed with a systemic (orthonex). Is there anything else I might try? Would a dormant oil spray work, and if so when would I use it? Also, there are small worms that are probably chomping the blossoms. What would work to prevent or kill them? How do worms can get into my flower boxes, that are at least 6 feet off the ground?

The trunk "crotch" has debris, and small crawly wormy insects. How can I treat? Is it too late? It's a lovely tree, provides great shade and privacy.
