With the summer season in full swing and temperatures soaring across the UK, gardeners are being urged to keep a vigilant eye on their greenery. Expert florist David Denyer from Eflorist has highlighted the need for extra care during the hotter months.

He has flagged that certain plants are particularly at risk during spells of high heat, especially those with large, delicate flowers or shallow root systems.

Some beloved UK garden staples are susceptible to heat stress.

For instance, hydrangeas can suffer sudden wilting and leaf scorch, while peonies with their hefty blooms may also succumb to the heat.

David notes that begonias and roses are heat-sensitive too, and if you've been busy planting new beds early this summer, it's crucial to monitor them closely.

Newly planted flowers with still-developing roots can quickly become overwhelmed by stress.

For those concerned about the sweltering heat wreaking havoc in their gardens, David has offered his best advice for maintaining plant health.

His primary tip concerns the timing of watering, reports the Express.

He advises: "Water before 9 am or after 7 pm. Midday sun evaporates water quickly and can even scorch foliage. Morning watering is ideal. It gives the soil time to absorb the moisture before heat sets in."

David also stresses the importance of ensuring water penetrates to where it's most needed.

"Surface watering doesn't cut it. Focus on slow, deep watering at the base of plants. For containers, make sure water reaches the roots by soaking the soil thoroughly."

Should your plants appear somewhat wilted, offering them some shade might be beneficial. David suggested: "Move potted plants to shaded patios, under trees, or behind taller plants. Use garden fleece, parasols, or even an old sheet to shield delicate flowers for the day."

David mentioned that you could also decrease the rate of water evaporation by placing potted plants in close proximity to each other.

He added, "This reduces the rate of evaporation and creates a mini microclimate to keep soil cooler and moister for longer."
