The last days of mild weather merge with the flamboyant hues of autumn leaves. Leaves start falling from trees to litter the ground with a beautiful carpet of yellow, orange and red. October is one of the most beautiful months of the year, certainly one of the nicest to be outdoors working on the garden tasks!

Grass and lawn in October

After having dethatched your lawn in September, October is the time to prepare your turf for the onslaught of cold weather.

• Apply a low-nitrogen, high-potash fall fertilizer to toughen grass before winter and discourage moss.
• Reduce mowing frequency and raise the blade. Grass cut too short is more vulnerable to cold and wet.
• If you love early color, plant small bulbs—grape hyacinth, crocus, snowdrop—right in the lawn. They’ll flower before spring mowing resumes.
• Rake or mulch fallen leaves every few days to prevent smothering and fungal patches.

Roses in October

• Repeat-blooming roses can flower until first frosts if you deadhead faithfully.
• Keep the base of bushes weed-free to reduce disease pressure and pests.
• Autumn moisture favors black spot and other fungi: remove and destroy yellowing leaves and plan a fungicide treatment (or organic equivalent) after leaf fall.

Garden flowers in October

It’s prime time to plant perennials and to divide mature clumps. Begin protecting the most cold-sensitive containers and refresh autumn planters.

• Set out pot-grown chrysanthemums for a November display.
• Pull out annuals that have finished and compost the healthy remains.
• Plant biennials for late fall or spring bloom: forget-me-not, primrose, pansy, wallflower…
• Plant the first spring bulbs: tulip, daffodil, crown imperial, grape hyacinth, snowdrop, hyacinth, crocus, ivy-leaf cyclamen…
• Divide perennials now to rejuvenate and multiply them.
• Plant your heath plants (heathers, azaleas, etc.) in acid soil mixes.

The vegetable patch in October

After an abundant summer harvest, winter vegetables take the stage alongside the last of the warm-season crops. Free plots can be sown to green manure to naturally feed the soil for spring.

• Finish harvesting late tomatoes, eggplants, zucchini, peppers.
• Store first ripe fall crops in a cool, dry, ventilated space (50–55°F / 10–12°C).
• Harvest mature squash, carrots, turnips, beets.
• Sow winter radishes and protect under cloches, tunnels, or in a cold frame.
• Spread well-rotted manure or compost on unused beds.
• Lift remaining root crops you intend to store; mulch those you’ll leave in the ground.
• Bring in celery and endives for forcing if desired.
• Plant garlic (pink/softneck types) for next summer’s harvest.
• Before severe frosts, lift or mulch parsnips.
• Pick corn salad (mâche) as needed.

Fruit trees and orchard

October is pivotal in the orchard: apples and pears reach maturity, while walnuts and chestnuts are ready for gathering.

• Harvest fruit you intend to store—especially apples and pears. Keep them in a dry, airy room and store carefully.
• If needed in your area, treat fruit trees (and olives) following integrated-pest-management guidelines.
• Pick the last grapes before they overripen and rot.
• Install grease bands (glue collars) to trap winter moths on susceptible trees: plum, apricot, cherry, apple.
• Tidy up small fruits: prune out fruited canes on raspberries, clean up strawberry beds and refresh mulch.

With weather still mild, it’s also a great month to plant new fruit trees—including kiwi (Actinidia)—so they settle before deep cold.

Trees and shrubs in October

Container-grown trees and shrubs planted now benefit from warm soil and autumn rains, especially where November brings deeper frosts.

• Prune summer-flowering shrubs lightly to shape.
• Deadhead lingering blooms and clear diseased material.
• Start spreading mulch around bases to protect roots from winter cold and to conserve moisture.

Terrace, balcony, decks

Plants vulnerable to freezing—geraniums, oleanders, citrus, bougainvillea—should be moved to frost-free quarters before cold spells.

• As with garden beds, remove spent annuals and replace with hardy biennials for spring.
• Scrub empty pots and boxes; refresh tired potting mix.
• Lightly prune climbers to balance and secure them against winter winds.

Bonus October checklist

• Ponds & water: Net ponds to keep leaves out; remove pumps or raise them above likely ice levels.
• Wildlife care: Leave a few undisturbed leaf piles for hedgehogs and overwintering pollinators; clean and refill bird feeders.
• Tool care: Clean, oil, and store tools; drain and coil hoses before the first hard freeze.
• Compost: Alternate green and brown layers (grass clippings/leaves) and keep the heap slightly moist for steady decomposition.
