October is one of the busiest gardening months in Saint John. The growing season is winding down, but it’s an excellent time to prepare your garden for winter and get a head start on next spring.
🍂 What to Do in October
Plant Spring-Blooming Bulbs
October is ideal for planting:
- Tulips
- Daffodils
- Crocuses
- Hyacinths
Plant them before the ground freezes so they can establish roots before winter.
Plant Garlic
Garlic is one of the best crops to plant in October in southern New Brunswick.
- Plant individual cloves 2–3 inches deep.
- Cover with mulch after the ground cools.
- Harvest next summer.
Clean Up Vegetable Gardens
- Remove dead tomato, bean, and squash plants.
- Pull weeds before they go to seed.
- Add healthy plant material to your compost pile.
Protect Perennials
After several hard frosts:
- Cut back diseased foliage.
- Leave some seed heads for birds.
- Apply mulch around sensitive plants.
Improve the Soil
Fall is an excellent time to:
- Add compost
- Spread aged manure
- Mulch garden beds
Winter weather helps work organic matter into the soil.
🐦 Support Wildlife
Consider leaving:
- Coneflower seed heads
- Sunflower heads
- Ornamental grasses
These provide food and shelter for birds throughout the winter.
🌡️ Typical October Weather in Saint John
Typical conditions include:
- Average highs: 10–14°C
- Average lows: 2–6°C
- First hard frost often occurs during October

Garden Planning for Next Year
October is also a great time to:
- Record what grew well this year.
- Sketch next year’s vegetable garden.

- Divide overcrowded perennials.
For Saint John gardeners, October is less about harvesting and more about setting up a healthy, productive garden for spring 2027. 🌷🧄🍁
