End of Spring to Start of Summer Gardening Guide
Preparing Your Garden for a Thriving Summer
As spring begins to fade and the warmer days of summer arrive, gardens across the UK burst into life. Lawns start growing faster, borders become fuller, vegetables begin cropping heavily, and suddenly the garden demands far more attention than it did just a few weeks ago.
Late spring and early summer are some of the most rewarding months in the gardening calendar - but they are also the most important for setting your garden up for success through the hotter months ahead. From feeding hungry plants and mulching borders, to watering correctly and planting summer colour, now is the perfect time to give your outdoor space a seasonal refresh.
At Dandy’s Nationwide Garden Supplies, we supply everything you need to prepare your garden for summer, including premium topsoil, compost, bark mulch, decorative aggregates, lawn products and more.
Feed Your Soil Before the Heat Arrives
Healthy gardens always start with healthy soil.
After months of spring growth, borders, containers and vegetable beds can quickly become depleted of nutrients. Before the hotter weather arrives, it’s important to replenish your soil with nutrient-rich compost and quality topsoil.
Adding fresh compost improves:
- Moisture retention
- Soil structure
- Root development
- Nutrient availability
- Overall plant health
For raised beds, borders and vegetable patches, a blend of compost and quality sandy loam topsoil creates the ideal growing environment for summer planting.

Mulch Borders to Lock in Moisture
One of the best things you can do for your garden at the end of spring is apply mulch.
A generous layer of bark mulch helps:
- Retain moisture during dry spells
- Reduce weed growth
- Keep roots cooler in hot weather
- Improve soil condition over time
- Create a neat, professional finish
When the sun beats down on bare soil, moisture evaporates rapidly. Mulching acts as insulation for your borders, helping plants cope better during heatwaves and reducing how often you need to water. Experts increasingly recommend soil protection and moisture management as summers become warmer and drier. (RHS)
Popular choices include:
- Ornamental Bark
- Pine Bark Nuggets
- Play Grade Bark
- Hardwood Chips

Water Smarter, Not More
As temperatures rise, many gardeners instinctively reach for the hosepipe - but watering properly is far more important than simply watering often.
The best practice is to:
- Water early in the morning or late evening
- Water deeply and less frequently
- Avoid watering in direct midday sun
- Focus on the roots rather than foliage
Deep watering encourages stronger root systems and helps plants become more drought resistant throughout summer. Early morning watering is widely recommended to reduce evaporation and minimise stress on plants.
Top tip: applying mulch after watering helps trap moisture in the soil for far longer.
Refresh Tired Lawns
Late spring is prime lawn season.
After a wet winter and rapid spring growth, many lawns begin to look patchy, compacted or tired by June. Early summer is the ideal time to:
- Repair bare patches
- Level uneven areas
- Topdress lawns
- Overseed thinning grass
- Feed your lawn
Using a quality BS3882 sandy loam topsoil can help improve drainage and encourage healthier grass growth.

Plant for Continuous Summer Colour
A common mistake in UK gardens is having everything flower at once in late spring, leaving borders looking tired later in the season. Gardening experts recommend mixing planting times and choosing long-flowering varieties to maintain colour throughout summer.
Great additions for summer colour include:
- Cosmos
- Verbena
- Lavender
- Geranium Rozanne
- Salvia
- Dahlias
- Hardy annuals
Container planting is also perfect at this time of year, especially for patios, balconies and smaller gardens.

Using fresh compost and decorative aggregates around pots can instantly brighten outdoor spaces while helping reduce weed growth and moisture loss.

Keep On Top of Weeds Early
Weeds grow incredibly quickly at this time of year thanks to warm soil and longer daylight hours.
Staying on top of them now saves huge amounts of work later in summer.
Simple ways to reduce weeds:
- Mulch borders
- Hoe regularly in dry weather
- Avoid leaving bare soil exposed
- Use membrane beneath decorative stone areas
A well-mulched garden is easier to maintain, looks tidier and conserves more moisture during hot weather.
Start Planning Outdoor Living Spaces
As the evenings become warmer, gardens naturally become an extension of the home.
Now is the perfect time to refresh:
- Garden seating areas
- Pathways
- Decorative borders
- Fire pit spaces
- Outdoor dining areas
Natural materials like gravel, slate and self-binding pathways create low-maintenance, stylish outdoor spaces that work beautifully in both modern and traditional gardens.
Popular options include:
- Plum Slate
- Cotswold Chippings
- Golden Gravel
- Self Binding Gravel

Layered planting, ornamental grasses and screening plants are also increasingly popular for creating sheltered, relaxing garden spaces. (Ideal Home)
Vegetable Garden Jobs for Early Summer
June is one of the busiest months in the kitchen garden.
Popular crops to sow and grow include:
- Courgettes
- Beetroot
- Carrots
- Lettuce
- Radishes
- French beans
- Herbs
Warmer soil and longer daylight hours make this one of the best periods for growth and harvesting.
Top tip: Regular harvesting encourages many vegetables and herbs to keep producing throughout summer.
For best results, use nutrient-rich growing media and ensure crops are watered consistently during dry spells.

Prepare for Heatwaves Before They Arrive
UK summers are becoming increasingly unpredictable, with sudden hot spells placing gardens under stress. The RHS predicts that climate resilience and water management will become even more important for gardeners in the coming years. (RHS)
A few simple preventative steps can make a huge difference:
- Mulch all borders
- Install water butts
- Improve soil organic matter
- Use drought-tolerant planting
- Group containers together to reduce moisture loss
- Water deeply rather than little and often
Healthy soil rich in compost and organic matter acts like a sponge, helping gardens survive prolonged dry periods far more effectively.
