Interesting tharg, I was considering 12 inch pots for mine but weren’t sure if that would be too roomy (can only mean more room to grow).
Ah love her heart ? so I was inspecting my largest sunflower and have noticed it’s got aphids on the stem and under the leaves ? where do these critters come from!? I don’t want my plants to be eaten before they even bloom. Have you spotted any aphids?
