What You Need To Know Before Growing Dill In Your Garden
If you plant dill in your garden or flowerbed, expect to spend a good amount of time managing it. This herb will grow quickly over time and may overtake your garden.
To limit its spread, you’ll want to keep dill contained to a designated area of your garden — one with ample room — and consider using rock or paving stones to create a border.
Don’t overseed the area: It's a good idea to plant dill in rows within that designated space, keeping them about 6 inches from row to row and about 2 inches from seed to seed.
The key to controlling dill is to keep it thinned, so thin the plants down to a handful of the heartiest seedlings when about 4 inches tall and then again at 12 inches tall.
Make sure to harvest your dill, and cut the plants back to leave 6 to 9 inches of the ferns in place to encourage regrowth. It often takes up to 90 days to reach full harvest.
Harvesting, thinning, and containing make dill a great garden herb to grow. Not taking these steps, however, and allowing dill in the ground to spread could spell garden trouble.
