The question is why is it wobbly? How long has it been this way? Have you checked the roots? If it is just wobbly because the plant is so big a rock on top of the dirt will help hold it.
My question is are the roots healthy? Wobbly could mean the roots are in trouble, and a rock will not help that at all.

I will check the roots when i can also i dont know how long its been that way

Thank you for the therad

Just chelcked the roots the seem ok so i add more rocks

"add more rocks' just a note: I find it impossible to determine how damp the soil is when there is stone mulch on top. Depending on the pot I would add one big stone or such., but if you are careful stone mulch can be used. Stush uses tomato cages on some of his big Sanseviera, that might be an alternative for you also.

The pot its in is big so i am using river rocks

Keve- You better not water it often. I give mine a drink about once a month...sometimes a littler longer than that. Remember,,,when you do water...no sips. Water thoroughly and let it drain out twice...then leave it alone til next month. Are you growing it on the fire escape? every 2 weeks I would if outside. Wait, you're in Queens, right? so prolly no fire escape. You should be good to go.

Ok
