Greetings all! just a quick note from personal experience with fertilizers. I would recommand Seasol and Powerfeed even to native varitities! Start with a small dilussion and work your way up. With natives its very touch and go all depending on the type of plant itself and not the species. I live on a nursry and give a huge varitity of natives the same doeses thoughout different growing periods. Some can handle it and others don't. The ones that dont like it or are sensitive get ripped out!
