My basil plants are thriving too much.
This is my thai basil:
And in the same pot lemon basil:
I've topped them quite a lot, as you can see in the bushy growth pattern.
They already started flowering months ago, even before I put them into the big pot. I read online that you just have to snip them off, and done.
But there are basically only flowers coming, and I don't want them to waste all their power into developing seeds.
Is this normal and just a part of their lives when they reach a certain size?
Try to keep the soil cooler, water with cold water. It looks like it’s in a very shallow planter right now so keeping the soil cool will be difficult. I’d put the plant in a deeper pot with more soil volume and wrap the pot in foil to reflect sunlight if the pot is in a place it gets sun all day. It might not solve the issue now that it’s already started but keeping the soil cool and moist will help slow it down or prevent it all together if you’re doing it from the start.
