Identifying Soil Creatures in Container Tomatoes

Shiny cobweb-like material suggests slug/snail trails, not nematodes (microscopic). Visible worms could be various larvae. Since it's a container, the simplest fix: repot in fresh sterile mix after thoroughly washing roots.

Quick Reset Protocol

1. Remove plant, gently wash all soil from roots
2. Discard old potting mix
3. Repot in new sterile container mix
4. Monitor — problems rarely recur in clean medium

This eliminates whatever's in the soil instantly. Your neem and homemade sprays are fine for foliage pests, but soil issues need a medium replacement.
