Sunflowers in Compost Poisonous
I have read several threads and articles stating that sunflower plants can be poisonous to other plants and should not be added to compost piles. Specifically, they contain phytotoxic???
I have a small,urban garden and I compost everything I can, though my compost bin is still small.
I understand that I should not exceed 20% of any one material for my pile.
All of that said, should I not compost the sunflowers I have growing? I feel it is such a loss as they would greatly increase my compost pile.
