October is the month when I stop pretending summer isn’t over. The clocks go back, the heating comes on, and my plants all suddenly look like they’ve moved into a different world. The light drops noticeably, the air dries out, and routines that worked perfectly in September suddenly need adjusting again. It’s a month of settling in and accepting that we’re in this for the long haul. Here’s what I’ve been learning about keeping plants happy through October.

What October Brings for Houseplants

October is a significant month in the plant calendar. Daylight hours are now down to around 10 or 11 across much of the Northern Hemisphere, and dropping fast. By the end of October, the clocks change in the UK and much of Europe, and in early November in the US. That single hour shift feels symbolic as much as practical — it’s the moment winter really begins for indoor plants.

Most houseplants are now in a clearly slower growth phase or fully dormant. You might see the occasional new leaf on fast growers like pothos or tradescantia, but the explosive growth of summer is gone. Many plants will produce no new growth at all between now and February or March.

This slowdown is natural and healthy. Trying to fight it by increasing feeding or moving plants to brighter spots generally doesn’t work and can actually cause more harm than good. The better approach is to accept the rhythm, adjust your care accordingly, and focus on maintaining stability and health rather than on active growth.

For Southern Hemisphere readers, October is spring, and the April and May posts in this series are much more relevant to where you are in the growing cycle right now.

The Central Heating Problem Starts in October

If there’s one thing that defines October for houseplant owners, it’s the return of central heating. And with it comes the single biggest indoor plant challenge of the winter: dry air.

Central heating efficiently removes moisture from indoor air. Humidity in a heated home can drop from a comfortable 50 per cent or so down to 20 to 30 per cent within days of switching the heating on. For tropical houseplants that prefer 50 to 70 per cent humidity, this is a genuine shock to the system.

The symptoms appear quickly. Crispy brown leaf edges, curling leaves, and premature leaf drop are all classic signs of low humidity. Calatheas, ferns, fittonias, and peace lilies are among the most sensitive. Even more tolerant plants like monstera and philodendron can start to look less vibrant in very dry air.

The solutions are the same ones we mentioned in January: grouping plants, using pebble trays, and using a small humidifier. But October is when you need to actually implement them rather than just think about them. Getting a humidifier running early makes a real difference before symptoms develop.

The RHS guide to humidity for houseplants covers the details of what different plants need and how to provide it practically.

Watering in October – Much Less Than You Think

October watering is one of the areas where people consistently go wrong, usually toward too much rather than too little. Growth has slowed significantly, temperatures are lower, and compost remains wet for much longer than in summer. The combination creates a significant risk of root rot if you’re still watering on a summer schedule.

For most tropical houseplants in October, watering once every week to ten days is probably about right, but as always, the soil check is the only reliable guide. Wait until the top two inches of compost are completely dry before watering again. For succulents and cacti, you can stretch this to two to three weeks quite comfortably now.

One practical October tip is to water in the morning rather than the evening. In cooler conditions, compost watered in the evening remains cold and wet overnight, when fungal root problems are most likely to develop. Morning watering allows the pot to begin drying out in the warmest part of the day.

The University of Maryland Extension houseplant guide offers solid advice on adjusting watering for the autumn and winter.

Stop Feeding Now – Or Very Soon

For most houseplants, October is the month to stop feeding altogether. Growth has slowed to the point that plants can’t effectively process nutrients. Fertiliser sitting unused in compost converts to salts that can damage roots, and the whole thing does more harm than good.

The exception is if you have plants that are still showing clear active growth. Some fast growers, such as pothos or tradescantia, may still be producing occasional new leaves in early October, especially if they’re near a bright window or under a grow light. These can continue with a very diluted feed until the growth stops.

For flowering plants such as cyclamen, orchids, and anthuriums that are blooming now or about to bloom, a diluted high-potassium feed every three to four weeks supports flowering without promoting unwanted leafy growth. Keep the concentration well below the recommended summer dose.

If you haven’t already, now is a good time to flush compost thoroughly with plain water to clear any fertiliser salt build-up from the summer feeding season. Water the pot generously three or four times in succession and let it drain completely each time.

Miracle-Gro’s seasonal feeding guide clearly explains the winter feeding approach for anyone seeking more detail.

Setting Up Grow Lights for Winter

If you’ve been thinking about grow lights and haven’t bought one yet, October is genuinely the last comfortable moment to set one up before you actually need it. By November, when light levels really drop, you’ll be grateful to already have everything running smoothly.

Grow lights make the biggest difference for a few specific plant categories. Herbs and edibles grown indoors absolutely need supplemental light to thrive through winter. Succulents and cacti, which require ample light even during their slow season, benefit from it. Any plant that struggled, looked leggy, or lost significant leaves last winter is a candidate for supplemental grow light support.

You don’t need anything complicated or expensive to start with. A simple full-spectrum LED bulb in an adjustable clip-on fitting is a perfectly good entry point. Position it 20 to 30 centimetres above the plant and run it for 12 to 14 hours a day using a simple timer plug.

For a wider range of plants or a larger collection, a dedicated LED grow light panel gives more even coverage. The Spruce’s grow light guide offers solid recommendations across a range of budgets and is updated regularly. For UK readers, Two Wests and Elliott stock a solid range of grow lights specifically aimed at houseplant enthusiasts.

October Is a Good Month for a Full Plant Audit

With the growing season effectively over, October is a good time to conduct a thorough audit of your entire collection. Assess each plant objectively and ask a few simple questions.

Did this plant thrive this year or just survive? Is it in the right spot for winter? Does it need repotting, and if so, is it better left until spring? Are there any pest or disease issues that need to be addressed before they worsen over winter? Do you still want this plant?

That last question sounds harsh, but it’s worth asking. A plant you don’t love or that keeps struggling is taking up space, light, and your time and energy. October is a good moment to make some considered decisions about rationalising your collection before winter.

The plants you do decide to keep through winter deserve a clean pot, clean leaves, and a well-considered position. A wipe down of all leaves with a damp cloth removes summer dust and prepares them to absorb every bit of available winter light.

Autumn Bulbs and Winter Flowering Plants

October brings some lovely opportunities on the buying side, too. Garden centres and online retailers are full of autumn- and winter-flowering plants this month, making brilliant additions to a home collection.

Cyclamen are widely available and absolutely at their best in October. They prefer cool conditions, making them ideal for hallways or rooms that aren’t heavily heated. Keep them away from direct heat sources, and they’ll flower for months.

Forced bulbs for indoor flowering are another great October project. Hyacinths, paperwhite narcissi, and amaryllis bulbs are all widely available now and can be started in October for flowers in December and January. Hyacinth and paperwhite bulbs can be grown in just water and pebbles, making them a satisfying, low-effort project.

The RHS guide to growing forced bulbs indoors provides detailed guidance on timing and preparation. For US readers, White Flower Farm has an excellent selection of forcing bulbs with clear instructions.

My October Plant Checklist

October is about accepting the season and adjusting accordingly. Here’s what I’m working through this month.

Turn on the humidifier or set up pebble trays as soon as the central heating goes on. Reduce watering significantly and check the soil before every watering. Stop feeding most plants, or move to a very diluted occasional feed for those still showing growth. Set up grow lights now rather than waiting until you need them. Conduct a full plant audit and determine winter positions for all areas. Wipe down leaves to remove dust and prepare plants for lower light. Start any forced bulbs for winter flowering. And resist the urge to do anything drastic – October is a month for settling in, not stirring things up.

For anything not covered here, the RHS and American Horticultural Society are the best places to dig deeper.

How are your plants settling in for autumn? I always find the shift to winter routines takes a few weeks to feel natural. Would love to know which plants are handling the change well in your home and which ones are complaining about it most.
