WE may well be seeing lower slug and snail numbers this summer thanks to colder weather in winter and the recent dry spells.
But mother nature never makes it easy for us. Instead – of course – there’s a new pest in town.
RHS members have found aphids to be the biggest problem this year[/caption]
Adam Woolcott told Sun Gardening how to get rid of garden pests[/caption]
Aphid levels have rocketed this year – and the RHS reckons it’s top of the list of gardening queries to their hotline.
There’s over 500 different species found in the UK – and can be red, yellow, black, green, brown or pink.
They feed by sucking sap from plants – and can cause severe damage – including distorted growth, sooty mould and plant viruses – and sometimes plant death.
Chelsea award winning gardener Adam Woolcott – and Webb ambassador – gave Sun Gardening some top tips on how to tackle the most common early summer pests.
APHIDS
Physically remove the aphids from the stems and leaves.
Use natural insecticidal soaps.
Blast off with water jets.
Encourage predators such as ladybirds, lacewings, and hoverflies
VINE WEEVIL
Both the adult vine weevil beetles and their larvae cause damage.
Adults — all female — chew distinctive ‘U-shaped’ notches in leaves, particularly on evergreen shrubs like rhododendrons, escallonias, and viburnums.
Underground: larvae feed on plant roots and can kill container plants like Heucheras.
Remove adults at night when they’re most active
Break the life cycle with biological controls such as nematodes (apply in spring and autumn when grubs are active) Chemical treatments are a last resort, but offer longer-term control
LILY BEETLE
The bright red beetles and their larvae are both covered in their excrement. They can strip a plant in days, affecting flowering and bulb health.
Remove beetles by hand where practical
Encourage wildlife into the garden. Birds and ground beetles will eat the larvae
Grow a resistant variety.
Tolerate some damage if you can — total eradication isn’t always necessary.
CATERPILLARS
Especially troublesome in veg patches. Cabbage white butterfly caterpillars love brassicas, while box tree caterpillars are spreading rapidly across the UK, stripping foliage as they go.
Remove the caterpillars by hand if you can and destroy any badly affected plants (if practical) to stop the infestation from spreading.
Use biological sprays like nematodes.
In some cases, hot water and a mild detergent can help. Ecover is on sale at Dunelm for £2.45.
As a last resort, chemical controls can be effective

Top tips, Gardening news, and a competition to win a £250 lawnmower
NEWS KING Charles made a surprise visit to Windsor Flower Show last Saturday. Celebrities including Alex Jones and Kirsty Gallacher were at the one-day show – which had wonderful village fair vibes, vegetable and cake competitions and fantastic floral displays.
TOP TIP JUNE is actually a good time to take Hydrangea cuttings – and get your own plants for free. They’ll have produced some soft green growth – which is what you want. Choose healthy, non flowering shoots that are 10-15cm long and cut just below the node (the leaf joint). Don’t collect cuttings from plants with leaves that are turning brown. And try to collect in the morning if you can.
Remove the lower leaves – leaving just one or two at the top.
Then dip the end in rooting powder or gel – then pop it straight in a pot. You could splash out on seeding and cutting compost – but multi purpose will do – just add a bit of grit or perlite. Then keep them out of direct sunlight and keep moist. They should have rooted within about a month.
NEWS A RARE ‘sheep-eating’ South American plant has flowered in an English primary school for the first time. The Puya Chilensis, with its iconic spike pattern, is normally found in the Andes in Chile. But after it was planted 10 years ago by school horticulturalist Louise Moreton, it has sent out a 10ft spike at Wicor Primary School in Portchester, Hants. It’s called a Sheep Catcher as it would normally entangle wildlife, hold onto it – and then when the animal died – would take the nutrients. Ms Moreton said it was exciting but a worrying sign of global warming.
WIN! Keep your lawn looking its best this summer by winning a Webb Classic Self Propelled Petrol Lawn Mower worth £249.99. To enter visit www.thesun.co.uk/WEBBCOMP or write to Sun Webb competition, PO Box 3190, Colchester, Essex, CO2 8GP. Include your name, age, email or phone. UK residents 18+ only. Entries close 11.59pm. July 5, 2025. T&Cs apply.
TOP TIP IF you want to get more flowers from your sedums (now called Hylotelephiums) and prevent them from collapsing – pinch them out around now. Pinch off around four sets of leaves down – which will make them bushier.
JOB OF THE WEEK Weeds thrive this month – keep on top of them by hoeing. Tie in sweet peas, and give your plants a good feed – liquid seaweed feed is great – and Tomorite works with nearly everything. Give agapanthus a high-potash feed every couple of weeks.
