Gardeners urged to use simple trick to stop plants dying in heatwave
As a mini-heatwave sweeps the UK with temperatures reaching 30C, a gardening expert has shared her essential tips to protect your plants against the elements
With temperatures set to hit 30C this week, gardens across the UK are now in need of some extra care.
As a mini heatwave sets in, gardening expert Hannah Rowson from seeds and bulb specialists J Parker's has offered her top advice for keeping outdoor spaces healthy and vibrant throughout the hottest part of the year.
Use rainy days to protect against future heatwaves
It might sound simple, but increasing how often you water your plants during the summer is key to keeping them from drying out. Hannah Rowson advises that the ideal time to water is early in the morning or late in the afternoon, when temperatures are cooler. This helps ensure that the water reaches the roots before it evaporates from the soil.
Unfortunately, with the heatwaves comes the threat of a hosepipe ban. To avoid any water supply issues, the expert suggests collecting rainwater in a water butt throughout the year. "Collecting rainwater using water butts will prevent you from being caught out by any hosepipe bans and offers a great alternative to keep your plants hydrated without relying on your main water supply," she said.
Shield container plants from direct sunlight in hot weather
Brits are also urged to shield container plants from direct sunlight in hot weather, reports the Express. If you have any plants in moveable containers, consider moving them into shaded areas. This handy trick will stop the plants from becoming overwhelmed by the sun's heat, keeping them healthy, colourful, and beautiful throughout the season.
Choose plants that can handle the heat
If you haven't already planted your garden display, then Hannah advises you to consider incorporating plants that are native to warmer climates into your summer garden design. She said: "Perennial plants like Lavender, Euphorbia, Heuchera, Pennisetum alopecuroides, and Cosmos are drought-tolerant plants that not only beat the heat but also add a touch of colour to your display."
Add mulch after planting to keep your soil full of nutrients
In hot weather, adding a thick layer of mulch has many benefits for your plants. Rawson said: "Mulch helps the soil retain moisture, which is essential for plant health during a heatwave. Also, it provides important nutrients that may be lacking in the soil, such as nitrogen and phosphorus."
Use natural fertilisers that target root health during the summer months
Another way of ensuring your soil is rich with nutrients over the summer months is by using fertilisers. However, "ensure you do not over fertilise the soil during summer, as luscious shrubs may struggle to keep up," the pro warns.
Rawson also recommended: "Add natural fertilisers like Mycorrhizal Fungi, these attach themselves to the roots of your plant to create richer root systems".

Met Office map reveals where Brits will bask in 29C heat this WEEK as thunderstorms & ‘intense' downpours to hit
The blistering conditions may be short lived HOT SPOT Met Office map reveals where Brits will bask in 29C heat this WEEK as thunderstorms & 'intense' downpours to hit Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A MAP reveals where Brits will be basking in 29C sunshine this week, but parts of the country will also be battered by thunderstorms. With temperatures set to climb again this week, many of us will have our sights set on a visit to the local boozer or take in the rays on the beach or green space. 5 Parts of southern England could see temperatures as high as 29C on Friday Credit: X/Met Office 5 People make their way through the rain in Southwark, London last Thursday Credit: PA 5 Revellers take in the sunshine in Lyme Regis, Dorset on June 2 Credit: Alamy Following a patch of gloomy grey weather and scattered rainfall, revellers may enjoy temperatures as high as 29C on Friday in southern England. But these sunny conditions may be short lived, Met Office Meteorologist Craig Snell explained, as a plum of warm air from Iberia and France is set to kick in on Wednesday evening, bringing a chance of thunderstorms. He said: "After Wednesday, we start to draw up some very warm and humid air from Iberia and France, and that will make it quite humid across much of the UK and that humidity will potentially spark off some thunderstorms. "From late Wednesday and especially into Thursday, we start to see the risk of some thunderstorms around and that will continue as we go through Thursday and Friday and potentially into Saturday as well." The Met Office added that it would begin to feel increasingly humid on Thursday, bringing about the increased risk of some heavy or even thundery showers developing. Craig continued: "By the time we get to midweek, it will feel very different out there, with quite humid night times also becoming a good deal warmer than what we have been experiencing over the last couple of nights, so probably borderline uncomfortable for some people by day." This comes just days after the Met Office issued a severe weather warning for thunderstorms across southern England. The predicted 40mm of rainfall on Saturday was higher than what England saw during the entire month of May. Met Office data shows England recorded 32.8mm of rain last month – almost half the usual monthly average. Meanwhile, Brits abroad have been urged not to drink the beer amid a scorching 42-degree heatwave from Africa. Brits warned 'don't drink beer' as 42C African heat plume strikes Spain Areas of the country roasted under extreme heat over the weekend - and the balmy temperatures look set to stay. Some spots were so hot the state forecaster, Aemet, was forced to issue weather warnings. Yellow and amber alerts came into force on Sunday - with Sevilla, Cordoba and Jaen in the south worst affected. Emergency guidance was issued to tourists and locals alike advising them on how to stay safe when it's sweltering. One suggestion likely unpopular with Brits on their hols was to avoid alcohol, because it has a dehydrating effect on the body. The advice is to drink water often, even if you're not thirsty, and avoid both alcohol and caffeine. It was also recommended to "dress smart", which means wearing loose-fitting clothes - particularly cotton or linen if possible. Lighter colours reflect the sun so can help you to stay cool. Another point is to simply stay indoors during times of peak temperatures, and certainly to avoid any strenuous activity under the sun. 5 A walker takes in the view of a field of poppies at Woodingdean near Brighton at the weekend Credit: Alamy

Gardening hack using 1 item will keep rose bushes blooming for longer in summer heat
Roses need special care once the temperature starts to rise. Expert shares the simple mulching hack that will keep rose bushes blooming for longer in summer heat Roses require extra attention during the scorching temperatures beyond mere watering, making it crucial to get them ready in June for a blooming summer. With rising heat, roses are prone to losing moisture swiftly through transpiration and soil evaporation, leading to their petals wilting. Failure to safeguard your roses can abruptly curtail their flowering as intense heat causes blooms to fade and shed. Nonetheless, Tat, a horticulturist and the brains behind 'Roses In Houston,' has divulged an optimal method to maintain rose hydration without incessant watering. Tat highlighted a common misconception, stating: "We all hear this advice to water, water and water during summer. But what if there is no rain and water restrictions in place? Does that mean it's the end of rose- gardening and we should call it quits?" Tat, however, recommends mulching as the superior approach to keep roses adequately watered, which involves covering the topsoil surrounding the plants with material for protection, reports the Express. Continuing her guidance, Tat shared: "Put on multiple layers of mulch (about two inches) at the base of your roses. Mulch helps retain moisture so that water and moisture won't escape from soil too fast after watering." She emphasised her preference for an eco-friendly option, adding: "I prefer all-natural, no-dye version of mulch like hardwood and cedar so when they break down, it's better for the soil." Mulching roses aids in reducing evaporation, thereby helping the soil retain more moisture and ensuring the roses stay hydrated throughout the summer. Mulch also provides insulation to the soil, preventing it from overheating, thus keeping the plant roots cool and undamaged regardless of the external temperature. Hardwood is particularly effective at retaining water and is often considered the best mulch to use if you need to keep roses hydrated for extended periods without watering them. If you're planning a holiday or anticipate hose restrictions in your area this summer, then hardwood mulch might be a good option. However, cedar mulch not only retains some water but also contains oils that act as natural pest repellents, which can help deter ants, aphids, rose slugs and spider mites from feasting on your rose petals. If you'll be home and able to water your roses regularly this summer, then consider using cedar mulch to help maintain their health. Regardless of how you choose to mulch your roses, ensure to water them deeply a few times a week during the summer to guarantee they continue to bloom throughout their growing season. The optimal time to water roses is early in the morning before 9am or late in the evening after 6pm when the sun has not risen, to minimise evaporation and help prolong the flowering period of the roses.

Exact date UK to be as hot as Barcelona with Brits basking in 27C Spanish plume
The weather this week is set to be a rollercoaster of torrential rain, thunder and roasting temperatures as parts of the UK are set to swelter in Mediterranean-style heat by Friday Forecasters are calling for a bizarre mix of boiling weather and thundery downpours this week as the mercury is predicted to hit 27C in some areas by Friday - as hot as Barcelona. Thunderstorms won't be quite what many of us had in mind as we enter June, however 27C temperatures following the tumultuous weather will be most welcome, MyLondon reports. According to the Met Office, Friday will be a roasting 27C, as hot as the Spanish holiday destination. Brits are set to be baking in summer heat at the end of the week but first we will be faced with thunderstorms and downpours, forecasters have warned. A weather front of low pressure is pushing south through Scotland and north west England and north Wales today bringing heavy rain and leaving temperatures feeling cooler in the north. Temperatures in the south are set to hit 20 or 21C today. More rain this evening will push eastwards and southwards and will see temperatures at 6 to 13 degrees north to south by Tuesday morning. The following day should see things starting to hot up into Tuesday with highs of 23 in London by the afternoon. The temperatures are set to keep rising over the course of the week, as is the humidity, and we could well be seeing some thunderstorms headed our way by Thursday. The weather system bringing blistering heat to the British Isles is riding on a plume thought to have originated in Spain and North Africa, forecasters say. In the coming weeks, the system will push up through the continent, making its way through France before crossing the Channel to make landfall in the UK. A Spanish plume is a specific summertime weather pattern in western Europe—especially the UK, Ireland, France, and the Low Countries—where very warm, moisture-laden air surges north or northeast from the Iberian Peninsula (often originating over the Sahara) and meets cooler Atlantic air aloft. The temperature, while only in the teens further north, are set to soar in the South East, the Met Office said. 'Warm on Wednesday with patchy cloud, sunny spells and the odd shower, this mainly in the morning. Trending warmer but breezy on Thursday,' their forecast for the week said.' 'Cloud will thicken through the morning and a risk of scattered thunderstorms is present in the afternoon. Very warm, potentially hot on Friday with sunshine and some cloud. A risk of scattered, heavy thunderstorms in the evening.'
