I have one sunburst tomato that did really well this year, it's still got alot of fruit to ripen. I was digging around the base to put some worm castings near the root system and found two grubs. They were almost clear w/ red on one end. They are bigger than BSFL. About 1" or longer if I was to uncurl it. Are they going to be a problem next year or even this fall?
