Can I cut my spider plant all the way to the soil and expect it to come back? It got over or under watered and all the tips are brown and getting worse.
Without correcting the problem, I don't think your plant will improve. Repotting might be a better solution. Remove any mushy roots at this time, and use a soil that dries quickly. When I've tried to grow plants from roots that I trimmed off of other plants, it doesn't work. Your plan sounds too similar to that for me to have much confidence in it.
I think my problem was that it was sitting in a saucer with some water in the bottom. I had it in a huge saucer with 3 other plants. It was in a hard place to reach. I have removed the saucer and have it where I can drain the saucer after I water it. Upon closer inspection, it has alot of new growth that doesn't have brown tips. I will just cut off the bad leaves and let the new grow out.
