You could try Fish Emulsion and suffocate the buggers, then remove them. I wouldn't use any kind of pesticide on ferns. You may have to defoliate the plant.

Wow. That's a bit more extreme than the drawings. I would reject that one if the nursery will let you exchange it or give you your money back. I'm sure it will grow but if it's a retail nursery that offers such satisfaction warranties, I would try to exchange it on the grounds that you're not happy with it. It looks like it was "j-rooted" at the tree farm or some other planting/rooting issue what makes it a poor specimen if you paid top retail dollar for it.

thanks Chimney guy for the info. I definitely notice a pop after the insert is first shut down. I haven't noticed the flame flare up lately so I guess I won't worry about it for now. Abbey

Many Ebay sellers don't accept returns unless the item is found to be other than was described ;0) Anglo, if you find an enthusiastic keeper, my SIL could use one too - my input has had no effect whatsoever. As of last month, she has three homes, and more dishes than she could possibly ever need for the three combined. She has absolutely no will power when it comes to china and porcelain - the Lenox and Vilroy and Boch, complete sets, in my basements cabinets proof of that. I have storage space to share, but really wouldn't mind the closed door dust proof shelving for my mothers Christmas decorations, other things that I'm now keeping for her since she downsized to a senior apartment. SILs sterling just left here last month after living 3 years in my basement. Service for 24! and now at the home just finished where I hope it sees lots of use. If I have need for formal or prettier service though, I'm in good shape...I borrow ;)
