Thanks to the UK’s increasingly hot summers, the RHS is considering relocating its Wisley hydrangeas to its northern Gardens. It’s a concerning move for hydrangea lovers in the south – but that doesn’t mean we should give up on our plants.

When you’re deciding where to plant hydrangeas, it’s always worth remembering that they’re woodland plants by nature, and they thrive in light shade. That means heatwaves and droughts are tricky conditions for the shrubs – but does that mean they’re no longer suitable for southern gardens?

Luckily, the answer is no. We spoke to RHS chief horticultural advisor Guy Barter to find out which varieties are most likely to thrive in southern gardens – and how to save the hydrangeas we already have.

This summer’s been a scorcher, and although there are ways to look after hydrangeas in a heatwave, I’ve spotted a lot of brown plants lately.

It makes sense, then, that the UK’s leading gardening charity is thinking about rehoming its RHS Wisley hydrangea collections in the north. We asked Guy about what’s motivating the move.

‘RHS Wisley is a very dry area,’ Guy said. ‘It’s got very dry, sandy soil, so some hydrangea varieties in some parts of the garden can be under pressure in hot, dry weather. Rather than giving ourselves a lot of work to keep them watered and cared for, we’re thinking about relocating them to our northern gardens, where it’s moister, the soil is more water-retentive, and they’ll need less looking after.’

It’s no secret that hydrangeas are perfect for damp gardens, and that’s where they’ll put on their best displays. That’s why RHS Wisley is going to keep some hydrangeas on its north-facing slopes, for example – and you might already be growing your plants in similar conditions.

‘In many cases, hydrangeas will be growing in quite clay soil,’ said Guy. ‘They’ll be growing on north-facing slopes in light shade, perhaps from the house or a wall, so they’ll be in good condition already.’

Some species perform better in hot, dry conditions though.

‘Hydrangea paniculata is a little bit tougher than the mopheads and lacecaps, and that’s one of the ones we use a lot at Wisley,’ said Guy.

Hydrangea paniculata ‘Vanilla Fraise’, which you can buy from Gardening Express, is a popular variety. It produces gorgeous, pyramid-shaped clusters of white-to-pink flowers. For potted plants that can be moved around the garden, Guy recommended Hydrangea serrata ‘Bluebird’ (available at Thompson & Morgan) for silvery blue flowerheads.

If you’ve already planted your hydrangea and it’s struggling, Guy says a few August hydrangea care tasks can help get them back on track.

‘Keep watering, give them liquid fertiliser every fortnight if the potted ones aren’t looking good, and if they’re getting scorched, move the pot somewhere shadier,’ he said.

Most importantly, Guy told us that it’s not the end of hydrangeas in the south.

‘Remember that we’re on the way down from summer now, so the nights are going to get longer and dewier, and the conditions are going to naturally get better for hydrangeas,’ Guy told us. ‘So, it’s well worth persisting and keeping them going.’

What you’ll need

The RHS’ news isn’t a sentence for hydrangeas in the south, but it does mean it’s wise to become more mindful about the way we grow the shrubs and the varieties that perform best in tough summers.

During hot weather, I’ve accepted that I need to empty my food waste bin daily or it will start to stink. But waste experts have just put me onto a slightly unconventional method that completely halts the decomposition process. All it requires is freezer space…

Even thinking about bad bin smells is enough to make me gag, so I welcome any method that promises to stop a bin from smelling the heat. Since the introduction of Simpler Recycling rules, every household in England will now have a food waste caddy in their kitchens.

If you’ve been struggling to stop your food waste bin from smelling, you might want to try this hack. Provided you have enough freezer space, all you have to do is put your food waste in the freezer and say goodbye to unpleasant aromas.

Can you put food waste in the freezer?

I’d first spotted this hack in the comment section of a TikTok and instantly baulked at the idea of putting my food waste in with my actual food. But the more I thought about it, the more it made sense – after all, freezing the food would halt the decomposition process – and so I decided to get an expert’s opinion.

‘Storing a food waste bin in the freezer can be a good idea, particularly during hot weather when food waste tends to break down more quickly, leaving unwanted odours. Freezing food waste helps slow bacterial growth, preventing the decomposition process that causes those unpleasant smells. This can make it a practical solution for households that struggle with smells in the kitchen,’ AO’s refrigeration expert, Jade Golding-Gault, explained to me.

‘The main benefit of this hack is it minimises unwanted odours in your kitchen. By keeping food waste frozen, you’re pausing the processes that cause smells to develop. It can also help deter fruit flies and other pests that are attracted to food waste, which is particularly helpful in the summer when they are more common. For households with infrequent food waste collections, it can be an easy way to keep kitchens clean and fresh between pick-ups.’

Of course, the main drawback of this hack is that it requires a lot of space. If you have a small kitchen and even smaller fridge/ freezer, this hack might not be suitable for you. For example, I have an under-the-counter fridge/ freezer, and my freezer is one small drawer – so unfortunately, this won’t be a hack I can use.

‘Storing food waste scraps in the freezer takes up valuable space that could be used for real food, especially if you have a small freezer. After taking the frozen waste out of the freezer, there is the chance that the scraps may turn soft and begin to leak water as they warm up on the way to the bin. Wet or heavy waste can also tear thin plastic bags, causing additional cleanup,’ says Ryan Kalia, a waste and bin specialist at Kingfisher Direct.

There are also hygiene considerations to take into account, too. Unwanted odours can transfer into the food in your freezer if your waste isn’t sealed properly, and you should remember it will immediately start decomposing again once you remove it from the freezer – so you should only store it for a limited time.

If you do lack freezer space to try this hack, don’t worry; here are a few small space-friendly methods to stop your food waste bin from smelling.

‘Freezing food waste can be a useful option if you are bothered by odours or pests in your kitchen, but it shouldn’t be necessary for every household. Regularly emptying your food waste bin, keeping it clean, using compostable liners and storing it away from direct sunlight can often be enough to keep odours under control. For those with limited freezer space, maintaining a clean food waste bin is usually a more practical long-term solution,’ concludes Jade.

It’s an unusual hack, but one that does work to reduce food waste smells – would you try it?
