I am not a plant expert but I suggest running foolish burial as well as 3 miracle fertilizers, card troopers and a debris dragon. Take out the monster that counts as 2 tribute for plants since tribute summoning is too slow at the moment. take out the upstarts too and put the cards I said before and add brd. show make it faster

-1 upstart
+ bunilla

Hello Tono, 

I agree with Pyro on the things he said and in addition to what he suggested, I suggest you running Crane Crane giving you access to Meliae (using dandy or card trooper or another crane crane as a material) that monster is godlike in plants decks. So make sure to have space for it.. 

Also there's a plant tuner called Mysterious Seed Mitra, check it out and you might run it :p  (at 1 would be enough)   note that with crane crane you'll get instant Barkion or Meliae. 

A last thing would be your choice of traps, you didn't ad TT, Evacuation and bth those are being stable, and I'd run them over prison for example. 

Now if you can't figure out how to find spaces, I'll mention the cards that you really don't need and they are:
 
Upstart, PODs, Rose witch, Monsters Reconsecration, the counter trap and that spell to take control of a monster. <-- those are all being debating cards in this deck.. not stable not consistent.  


I hope I helped <3
