Each year, Halloween sparks a surge in pumpkin purchases across the UK, with an estimated 17 to 30 million pumpkins bought for carving and decoration. Yet, behind the festive glow lies a startling issue of food waste: around 18,000 tonnes of pumpkins are discarded annually. Studies suggest that more than half of all pumpkins bought end up in the bin, representing not only wasted food but also the unnecessary use of land, water, and energy in their production.

Beards & Daisies, one of the UK’s largest houseplant companies, is urging households to think twice before discarding their pumpkins this Halloween. The company has compiled real data, expert insights, and top tips from its environmentally minded founders to help people repurpose pumpkins instead of throwing them away.

From delicious recipes to eco-friendly composting ideas, these practical suggestions show how families can celebrate the season sustainably, reduce waste, and make the most of their pumpkins long after the carving is done.

Did you know? Pumpkins should NOT be left outside for wild animals

Most people assume leftover Halloween pumpkins are harmless for wildlife, but that’s not the case. Jo Lambell, founder of Beards & Daisies, warns: “You actually shouldn’t leave pumpkins outside, especially in natural areas, because they can make wildlife like hedgehogs and deer sick, attract pests, and disrupt delicate ecosystems. Pumpkins are not a natural part of their diet and can cause stomach problems, particularly for animals like hedgehogs who are preparing for hibernation.”

How UK Households Can Safely Repurpose Pumpkins This Autumn

Wholesome Pumpkin Recipes - Instead of tossing your carved pumpkin, turn your pumpkin into hearty soups, creamy pies, roasted sides, or smoothies. Simply scoop out the flesh, remove seeds, and roast or boil until soft.

Pumpkin Seeds Snacks - Don’t waste the seeds! Rinse them to remove any pulp, pat dry, and roast in the oven with olive oil, salt, or spices such as paprika or cinnamon. These make a crunchy, protein-packed snack for humans.

Compost & Garden Fertiliser - Chop up your leftover pumpkin and add it to your compost bin or bury it in your garden soil. It decomposes quickly, enriching the soil with vitamins and nutrients that help flowers, vegetables, and shrubs thrive. Jo says, “Using pumpkins as compost closes the loop on Halloween waste. Instead of ending up in landfill, your pumpkin becomes food for the soil, encouraging healthy growth next season.”

Animal-Friendly Treats - Pumpkins are safe for pets and wildlife. Dogs can enjoy small cubes of baked pumpkin or it can be mixed into their meals, providing a healthy boost of fiber and vitamins. Roasted pumpkin chunks can also be placed in bird feeders for wildlife. Jo comments, “It’s a fantastic way to give back to your garden ecosystem. Dogs, birds, and other small wildlife love pumpkins, and it’s completely natural and safe for them when cooked.”

Plant a Pumpkin Patch - Save seeds from your pumpkins and plant them next spring. Sow them directly into garden soil or pots, keeping them well-watered and protected from frost. Pumpkins grow quickly and can produce fruits by late summer. Jo notes, “Even small garden spaces can grow a few pumpkin plants. It’s a rewarding project for families and helps create a sustainable, homegrown Halloween for next year.”

DIY Natural Decor - Repurpose pumpkins as natural planters or autumnal centrepieces, then do one of the above. Hollow out the pumpkin, leaving a sturdy base, and fill it with soil and seasonal plants like chrysanthemums, herbs, or succulents. You can even use them as candle holders or vases. Jo says, “Transforming pumpkins into decor extends their lifespan, reduces waste, and adds a beautiful, seasonal touch to your home, all without harming the environment.”
