Gardening & Horticulture — 2026-10-21
Gardeners are racing against the frost, with urgent advice to protect tender plants and plant hardy crops like garlic and onions before the ground freezes. Meanwhile, the UK government has unveiled a major plan to boost organic farming, and sustainable practices like permaculture and urban farming continue to gain traction as key strategies for resilience.

What to Plant & Do Right Now
With "Jack Frost" arriving, immediate action is required to protect vulnerable vegetation. Tropical plants can suffer damage below 45°F, while hardier species withstand temperatures near 28°F, making it critical to cover or move sensitive plants.
In the South, particularly South Carolina, October is the prime month for planting garlic, onions, pansies, and spring bulbs. Gardeners are also advised to manage lawns and prepare for drought conditions while enjoying fall flowers like mums.
For those in the UK, the Royal Horticultural Society (RHS) recommends planting out spring cabbages now, ensuring they are netted for protection against pigeons. Hardy lettuces sown in early autumn can survive winter with protection, allowing for hearting up in mid-spring.

Permaculture remains a vital framework for 2026, with resources highlighting how to apply sustainable practices to optimize resources and care for the environment. The Autumn 2026 issue of Permaculture magazine focuses on regenerative solutions for communities.
Urban farming techniques are being compared for their space, water, and cost efficiency. Rooftop farms, community gardens, vertical farms, and hydroponics are all evaluated for their suitability in city environments, with real-world examples provided for implementation.
Community Spotlight
Gardeners are sharing resilience tips after severe weather. One user noted that hail can shred corn and tomatoes, but plants are more resilient than they appear. The community advised standing corn up with bamboo stakes and noted that peppers often recover, though at the cost of harvest time.
For planning future gardens, users recommend interplanting with nasturtium, marigolds, and dill to deter cucumber beetles. Additionally, planting basil and borage near tomatoes is suggested to attract beneficial wasps for dealing with tomato hornworms.
