Seasonal Guide

What to Do in the Garden This October

October is a month of real change in the garden. Summer displays are reaching the end of their season, temperatures are falling and shorter days mean it is time to prepare properly for autumn and winter.

But this isn't simply a month for clearing away. There is plenty we can still plant, improve and enjoy.

Hellebores can bring valuable interest through winter and into early spring, while autumn and winter containers, hanging baskets and entrance displays can keep the most visible parts of the garden looking welcoming as summer colour disappears.

October is also the time to think seriously about tender plants. Chillies, pelargoniums and other tender perennials you want to keep need suitable protection before frost arrives.

And as our attention gradually moves away from the summer garden, it is a good opportunity to look indoors too. Houseplants are entering a different period of growth, so watering, position and general care all deserve another look.

In this guide, we'll work through the most useful October jobs and help you decide what to plant, what to protect, what to refresh and what can safely wait.

Need to know

  • Don't remove a good summer display simply because October has arrived. Keep worthwhile plants going while conditions allow.
  • Refresh containers and baskets that are genuinely past their best with plants chosen for autumn and winter interest.
  • October is an excellent time to look ahead and add hardy plants that will establish before the coldest part of winter.
  • Hellebores are particularly useful for adding winter and early-spring interest to suitable positions.
  • Decide which chillies, pelargoniums and other tender plants you want to keep and move them to suitable frost-free protection before damaging cold weather arrives.
  • Always inspect plants for pests and problems before bringing them into a greenhouse, conservatory or home.
  • Spring-flowering bulbs can be planted during autumn, although some bulbs have their own preferred planting times.
  • Check containers and baskets for good drainage as wetter weather becomes more likely.
  • Houseplants generally use water more slowly as light levels and growth reduce, so check the compost rather than continuing a summer watering routine.
  • Autumn tidying should be selective. Remove material that is diseased, damaged or causing problems, but don't assume the whole garden needs cutting back.

Decide What to Keep and What to Refresh

Start October by walking around the garden rather than immediately reaching for the secateurs.

Some summer containers and baskets may still be giving plenty of colour. If they remain healthy and attractive, there is no reason to remove them simply because the season has changed.

Others will be telling a different story. Sparse growth, tired plants and displays that require constant work to remain presentable are usually signs that it is time for a change.

Instead of trying to rescue every fading display, decide whether each one should be kept, improved or refreshed.

This gradual changeover lets you enjoy the last of summer while beginning to create a garden that feels right for autumn and winter.

Refresh Containers, Baskets and Entrances for Autumn and Winter

Once a summer display has genuinely finished, October is a good opportunity to give it a new purpose.

Start with the places that make the greatest difference: the front door, patio, window boxes and hanging baskets you see every day.

Before replanting, remove old roots and tired plants, check that drainage holes are clear and assess whether the existing compost is suitable for the next display or needs refreshing or replacing.

When choosing plants, think about their different roles rather than simply selecting individual plants that look attractive on the bench.

A successful autumn and winter display may combine structure with seasonal flowers, interesting foliage, contrasting textures and lower-growing or trailing plants.

Arrange everything before planting so you can judge the balance of the finished display.

Our autumn and winter Use Case Collections are designed around these sorts of gardening jobs, helping you create a coordinated result without having to choose every plant independently.

Plant Hellebores for Winter and Early-Spring Interest

Hellebores come into their own when much of the garden is quiet, making October a natural time to start thinking about them.

They can provide valuable flowers through winter and into early spring, depending on the type, while their foliage can also contribute useful structure.

Most commonly grown hellebores appreciate some shade and a soil that retains moisture without remaining waterlogged.

Take time to choose the position properly. A hellebore is not simply a temporary seasonal display plant; in the right place it can become a long-term part of the garden.

When planting, prepare the ground well, avoid burying the plant too deeply and water it in thoroughly. Continue checking newly planted hellebores during dry periods while their roots establish.

Think about where you will see the flowers too. A position near a path, entrance or frequently viewed part of the garden can help you appreciate them during the colder months.

Protect Chillies, Pelargoniums and Other Tender Plants

By October, protecting tender plants should move higher up the list.

If you have chillies, pelargoniums or other tender perennials you want to keep, don't wait until frost damage tells you it is time to act.

First decide which plants are worth overwintering and where you can provide the conditions they need.

Depending on the plant, this may be a greenhouse, conservatory or another suitable light, frost-free position.

Before anything comes under cover, inspect it carefully. Look underneath leaves, around stems and across the compost surface for signs of pests or disease. Remove dead and damaged material and deal with problems before putting the plant alongside others.

Where appropriate, you might also take cuttings rather than trying to overwinter every large plant.

The important thing is to have a plan before a cold night forces you to make hurried decisions.

Plant Now for the Months Ahead

October gardening isn't only about winter preparation. Some of the most satisfying jobs this month are about what comes next.

Autumn is an important planting period for many hardy plants. The soil retains some warmth from summer while conditions are generally becoming cooler and moister, helping newly planted roots establish.

It is also spring-bulb planting season. Look around the garden now and identify the places that lacked early colour this year.

Bulbs can be incorporated into borders and containers, helping to create another layer of interest before many later perennials begin flowering.

Not every bulb has exactly the same ideal planting time, so check the needs of the bulbs you have chosen rather than treating them all identically.

A little work in October can give you something to look forward to through the darker months.

Prepare for Wetter and Windier Weather

As autumn progresses, drainage and stability become increasingly important.

Check containers to make sure excess water can escape freely. Clear blocked drainage holes where necessary and don't allow pots to sit permanently in water.

Hanging baskets also deserve attention. Check brackets, chains and fixings, particularly in exposed positions.

Remember that a wet basket can be considerably heavier than a dry one.

Remove fallen leaves where they are covering small plants, blocking drainage or making paths slippery, and check taller plants for damaged supports.

You don't need to make the garden spotless. The aim is to deal with things that could cause problems while allowing autumn to remain autumn.

Change the Way You Water

One of the easiest October mistakes is to continue watering exactly as you did during summer.

Cooler temperatures, shorter days and slower growth generally mean plants use water less quickly.

But that doesn't mean everything should be left to the rain.

Newly planted plants need monitoring while they establish, and containers beneath porches, house eaves or other sheltered positions may receive surprisingly little rainfall.

Put a finger into the compost or check the soil before watering and respond to what you find.

This becomes increasingly important as temperatures fall. Plants need the right amount of moisture, not a fixed amount delivered according to the calendar.

Turn Your Attention to Houseplants

As the outdoor garden slows down, October is a good month to turn some attention indoors.

Houseplants are responding to shorter days and lower light levels too.

Start by checking their positions. A spot that provided plenty of indirect light during summer may become considerably darker during autumn and winter.

Watering also needs adjusting. Many houseplants will use moisture more slowly as growth reduces, so check the compost before reaching for the watering can.

Remove damaged leaves, clean dusty foliage where appropriate and inspect plants carefully for pests.

If you have brought plants indoors from outside, keep an especially close eye on them before placing them amongst established houseplants.

The key is not to suddenly start doing more to your houseplants. It is to notice how their needs are changing.

Alan's Top Tip

October is one of those months when a little work at the right time can save a lot of work later.

Don't wait for the first frost before deciding what to do with tender plants. Work out which chillies, pelargoniums and other tender perennials you want to keep, check them carefully and prepare somewhere suitable for them before cold weather forces the decision.

At the same time, don't think that the garden is closing down.

Refresh the displays that have finished, introduce plants such as hellebores for interest through the colder months and start planting for the garden you'll enjoy next spring.

My approach in October is simple: protect what won't survive the cold, plant for what comes next and don't tidy away everything that still has a purpose.
