Good to have you on the forum
Not a great herb grower....but grow a few
Can you increase the depth of soil there? No chance of digging deeper? Or add compost to raise the level?
You need to remove all roots ....thorough digging now is essential. Every trace of mint, blackberry etc, ok?
I would then add fertiliser.......fish blood and bond, chicken pellets, etc.....before any planting.
Seeds should germinate now but check each seed packet. Maybe buy the odd plant like mint, thyme and oregano. I would not put any of these in your soil....instead pot these up. They are invasive if planted in the ground and will simply take over
Best of luck ken
