6 Self-Seeding Plants You Should be Growing in Your Backyard for a (Mostly) Self-Sufficient Garden

Work smarter, not harder — that's been a big mantra this year. Besides applying it to your jobs and chores, you can also adopt this clever phrase into your gardening. And we've found one of the best ways to do it — self-seeding plants.

So we consulted the experts and they've given us some brilliant insight on what we should be growing and how to care for these new additions. If you want a garden that looks after itself year after year, self-seeding plants are a good low maintenance garden idea .

The magic of it all lies in the fact that they're self-seeding, which simply means that you sow the seeds once and let the flowers prosper and regrow on their own. Low-maintenance, money-saving, and bunches of gorgeous petalled florals — that's a win-win.

1. Calendula

Gardening expert Tony O'Neill tells us that calendulas are one of the top self-seeding flowers to bring into your backyard. He explains that these bright orange blooms attract pollinators that help disperse their seeds all around the flower beds.

'They prefer full sun and well-drained soil,' he says. 'And don't forget to deadhead spent flowers to encourage more blooms.'

Additionally, calendula is also one of the best edible flowers to grow in your garden . You can cut them for vibrant in-house bouquets or add them to your summer salads for a floral garnish.

'Their vibrant orange blossoms bloom throughout summer and generously drop seeds,' he notes. 'They do well in poor, dry soil and full sun.'

Sal also tells us that the seeds remain dormant through winter and germinate once temperatures rise in spring. So this gives you a pre-prepped set of blossoms to look forward to as the seasons flip by.

FAQs

How to care for your self-seeding garden?

Tony tells us that self-seeding gardens are fairly easy to handle and encourages gardeners to prune when needed. Remember, you'll need the right pruning tools for this.

'While deadheading can encourage more blooms, leaving some flowers to go to seed will ensure they reseed for the next season,' he says. 'And apply a thin layer of mulch around self-seeding plants to retain moisture and suppress weeds without hindering seed germination.'

Besides the basics, Tony also recommends avoiding disturbance to the soil where self-seeding plants are growing to allow seeds to germinate naturally.

How to help the plants self-seed?

To help these plants self-seed, Sal recommends avoiding deadheading them after the first bloom to let the seeds fully develop. Understanding when to deadhead perennials and annuals is essential for a healthy garden. 'Then either shake the dried seed heads over the soil to drop the seeds or let the wind naturally disperse them,' he says. 'Rake the area lightly to ensure good seed-to-soil contact.'

He encourages gardeners to only water weekly, as the seeds need warmth to germinate. 'The following spring, you’ll be rewarded with new seedlings,' he says. 'Then you can either transplant or thin out your fresh crops.'
