Recently Repotted Plants Have Roots Coming Out Bottom! Help!
So I repotted some plants on 9/3/12, approximately 7 weeks ago and some now have the roots coming out the bottom.
I made sure I placed enough soil to reach at least half of the pot before I placed the plant in while repotting so I don't know how the roots are coming out the bottom so soon.
They are in bigger pots (most were 6 inch plants and were repotted in about 8 and 3/4 pots).
I have a pothos at work that was rooting in water and I repotted it in an 8 inch pot and I saw a root coming out the bottom yesterday. I also have a Peace Lily I bought in April and roots are coming out the bottom as well (its at work too).
What do you all recommend that I do? I don't know why the roots would be coming out the bottom so soon and the pots they are in should be a good size (I've read the many forums on here about going too big).
Should I just take the plant out of the current pot, add more soil to the bottom and then place it higher up? Is that be a good idea? Will the plant be OK?
I don't want to harm them.
Also, I have a some questions regarding the Peace Lily. When I bought it in April, it was blooming. It stopped in August and hasn't bloomed since. New leaves are growing but no flowers. Is this normal? Should I give it plant food to bloom? Also the tips are browning and some of the leaves also have brown spots. What can be the cause of this? It is under flourescent light at work. Any suggestions?
