Introduction: The Perfect Time for Garden Planning
Autumn is often overlooked as a planting season, but in the UK climate, it's actually one of the best times to add new plants to your garden. The soil is still warm from summer but the cooler air temperatures reduce stress on new plantings. Plus, autumn rainfall usually means less watering for you!
At Copaipsych Landscaping, we often recommend our clients use this season to prepare for a spectacular spring display. In this article, we'll explore the best plants to add to your garden this autumn, focusing on options that thrive in the British climate.
Spring-Flowering Bulbs
Autumn is the perfect time to plant spring-flowering bulbs. Getting them into the ground now gives them time to establish roots before winter sets in.
Top Bulbs to Plant in Autumn:
- Daffodils (Narcissus) - Plant in September or October for a cheerful display in March and April. Choose varieties like 'Tête-à-Tête' for smaller gardens or 'Dutch Master' for classic yellow blooms.
- Tulips (Tulipa) - Wait until November to plant tulips to reduce the risk of disease. Consider layering different varieties for a prolonged flowering period.
- Crocus - Plant these early-flowering bulbs in September or October, about 10cm deep in well-drained soil.
- Snowdrops (Galanthus) - These hardy bulbs should be planted "in the green" (with leaves intact) if possible, but dry bulbs can also be planted in autumn.
- Alliums - Plant these architectural beauties in September or October for striking purple globes in late spring and early summer.

Trees and Shrubs
Autumn is ideal for planting trees and shrubs. The still-warm soil encourages root growth, while cooler air temperatures reduce stress on the plants as they establish.
Recommended Trees for UK Gardens:
- Acer palmatum (Japanese Maple) - Choose a sheltered spot with some shade for these beautiful trees with stunning autumn colour.
- Amelanchier lamarckii (Juneberry) - A multi-season interest tree with spring blossoms, summer berries, and autumn colour.
- Betula utilis var. jacquemontii (Himalayan Birch) - Known for its striking white bark, perfect as a statement tree.
Shrubs to Plant in Autumn:
- Viburnum tinus - An evergreen shrub with winter flowers and berries.
- Hydrangea paniculata varieties - For late summer flowers that persist into autumn.
- Mahonia - For architectural form and winter flowers.
- Sarcococca (Sweet Box) - For winter fragrance and evergreen structure.
Perennials and Grasses
While spring is traditionally associated with perennial planting, autumn is actually an excellent time to establish these garden staples.
Perennials to Plant Now:
- Helleborus (Christmas Rose) - For winter and early spring flowers.
- Aster - For late colour that supports pollinators.
- Geranium (Cranesbill) - Hardy varieties that establish well when planted in autumn.
- Heuchera - For year-round foliage interest.
Ornamental Grasses:
Autumn is an ideal time to plant ornamental grasses such as Miscanthus, Calamagrostis, and Festuca. They'll establish roots over winter ready for growth in spring.

Winter Vegetables
Don't forget the vegetable garden! Autumn is the time to plant several winter crops:
- Garlic - Plant individual cloves in October or November.
- Broad beans - Autumn-sown varieties like 'Aquadulce Claudia' can be planted in November.
- Onion sets - Plant autumn varieties like 'Radar' or 'Electric' now.
- Spring cabbage - Transplant seedlings in autumn for an early spring harvest.
For smaller spaces, consider growing winter salads like winter lettuce, mizuna, and lamb's lettuce in containers near the house for easy harvesting.
Autumn Planting Tips
- Prepare the soil thoroughly before planting, incorporating organic matter like compost to improve soil structure.
- Water well after planting and continue to monitor soil moisture until plants are established.
- Apply a layer of mulch around new plantings to suppress weeds and retain moisture.
- Consider frost protection for less hardy plants, especially in northern regions of the UK.
- Don't forget to label what you've planted, especially bulbs which won't be visible over winter.
