There comes a time when you just need to let go. I know how hard that can be for gardeners. Letting your garden go to seed, so to speak, can be quite rewarding.
Sunflowers, Black-eyed Susans, Yarrow, Purple Coneflowers and many more varieties can feed birds throughout winter.
Many of these varieties will also self-seed and produce new plants without any effort on your part.
Herbs act in the same way. Dill and arugula for example will reseed if left untouched.
Remember to keep these plants in check to discourage a total takeover.
Set aside an area where you feel comfortable to let nature take its course. You can help out a bit by scattering seed or cutting back aggressive plants.
Not all seeds will take hold. It’s unlikely a jungle will occur. If it isn’t to your liking come spring, remove or transplant the new plants.
When its time to let go you will know it. In the meantime you will have helped birds and beneficial insects get through winter.
