can you have a trim using a supershroom ? someone said you can t

Depends on what critter you need to do the trim.  If you need a unicorn, you have to have the mushroom that attracts it (and, thus, can't use a supershroom).  Otherwise, you can use any mushroom (or no mushroom) as you please.

want top badger soon - would a little rosa and a sundragon planted now, mess up the top giraffes and top hh, that I am doing first? guess the herb may be a deterrent for something - I am short on strategy for badger late in the trail!

will choose the blue pot that has badger and elephant early - out of the two I have, for the third blue trail! order is very important.

lots of toparies have sprung up - a dozen new top black uni gardens! helped me a LOT!

The rosa will attract skunks to low veggies, and the sundragon will attract brown bunnies and hares. 

definitely will use high platters for giraffe/top giraffes; and birthday cake for the hedgehogs/topiary hedgehogs then -  birthday cake may save the day and let me grow rosa and sundragon to help with later badger/top badger, in peace; while giraffe and hh collecting  . . . woohoo! will plant rosa and sundragon, when pull the bonsais.

will reach level 42 in eleven hours - another free spot will soon be available for a yellow daisy, for the badger!

How do you get Topiary seeds.

By spotting topiary wildlife.  You can check the "topiary" section in the wildlife guide for more information.

(You really only need a handful of seeds to start, as the seeds mount up as you do the spotting for the challenge.)

Thanks so much for your reply, I'll look into that.
