Autumn - Why You Should Plant Now
Autumn is often overlooked in favour of spring when it comes to gardening, but it's actually one of the best times to plant shrubs and perennials in UK gardens. As the days begin to cool and the soil retains the warmth of summer, conditions become ideal for establishing strong, healthy roots before winter sets in.
Why Autumn is Ideal for Planting
Unlike spring, which can bring unpredictable weather and fluctuating temperatures, autumn offers a more stable and gentle environment for young plants. The soil is still warm from the summer sun, encouraging rapid root growth, while cooler air temperatures reduce stress on newly planted shrubs and perennials. There's also typically more rainfall, reducing the need for constant watering.
Planting in autumn allows your plants to settle in and establish a solid root system before going dormant in winter. Come spring, they’ll be ready to burst into growth and bloom earlier and more vigorously than spring-planted counterparts.
Best Shrubs to Plant in Autumn
Autumn is a great time to plant a wide variety of shrubs, especially those that provide winter interest or early spring flowers. Some excellent choices for UK gardens include:
-
Viburnum tinus – Evergreen and tolerant of shade, this shrub provides white winter flowers and berries.
-
Cornus (Dogwood) – Known for striking winter stems in red or orange, Cornus brings colour to the colder months.
-
Sarcococca confusa – A small evergreen shrub with glossy leaves and highly fragrant winter blooms.
-
Mahonia – With architectural foliage and cheerful yellow flowers in late autumn to winter, Mahonia adds structure and scent.
Perennials to Plant in Autumn
Planting perennials in autumn gives them a head start, ensuring they return stronger next year. Some excellent choices include:
-
Geranium (Cranesbill) – Hardy and reliable, these perennials offer beautiful blooms and good ground cover.
-
Echinacea – Attractive to pollinators and great for adding bold colour in late summer.
-
Heuchera – Loved for its colourful foliage, Heuchera provides year-round interest and thrives in shady spots.
-
Rudbeckia – Known for their vibrant yellow flowers, Rudbeckias extend the flowering season well into autumn.
Planting Tips for Autumn Success
-
Prepare the soil: Clear away weeds and work in compost or well-rotted manure to improve soil structure and fertility.
-
Water well: Even though autumn brings rain, it’s important to water thoroughly after planting to help roots establish.
-
Mulch: Add a layer of mulch around your plants to retain moisture and protect roots from temperature fluctuations.
-
Avoid frost pockets: Plant in sheltered areas where cold air doesn’t settle, especially for more tender varieties.
-
Check spacing: Plants may be small now, but ensure you give them room to grow by respecting their mature spread.
Time to Get planting!
Autumn planting sets your garden up for success. By taking advantage of favourable soil conditions and less plant stress, your shrubs and perennials will thrive come spring. It’s also a great way to get ahead while the rest of the garden is winding down. So grab a spade, pick out some favourite plants, and make the most of the autumn planting window. Your garden will thank you next year.
