Getting your garden summer-ready: the complete checklist

Getting your garden summer-ready: it is about more than watering

Summer is coming, and with it the promise of long evenings outdoors, meals under open skies and a garden at its absolute best. But a garden that looks glorious in June and turns into a parched wasteland by August is nobody's idea of a good time. The secret is preparation. Put the right systems in place now and you will enjoy the whole season without spending every evening with a hose in your hand.

This is not a list of nice-to-do projects. This is the checklist that makes your garden heat-proof, drought-proof and holiday-proof.

Setting up your irrigation system

Water is the single biggest concern in summer. A few weeks without rain and even established borders start to suffer. The best investment you can make is a decent watering system.

Drip irrigation

A soaker hose or drip line running through your borders is the most efficient way to water. It delivers moisture directly to the roots, minimises evaporation and keeps the foliage dry, which prevents fungal diseases. Lay the hose in a meandering pattern through the bed and cover it with mulch so it disappears from view.

Automatic timer

A watering timer on your outdoor tap costs between twenty and eighty pounds and saves an enormous amount of effort. Set it to run early in the morning, before sunrise, when evaporation is at its lowest. Water deeply two or three times a week rather than lightly every day. Deep watering encourages roots to grow downward, making plants far more drought-tolerant.

Check rain butts

If you have water butts, check they are properly connected to your downpipes and that the taps are not dripping. A full water butt at the start of summer is worth its weight in gold. Consider adding a second one if you only have one.

Mulching: the unsung hero of the summer garden

Mulch is the most underrated tool in the garden. A five to seven centimetre layer of organic material on your borders does three things at once: it retains moisture, suppresses weeds and regulates soil temperature.

Materials that work well:

• Composted bark chips (the most popular choice)
• Garden compost
• Straw or hay in the vegetable garden
• Composted leaf mould
• Cocoa shells (wonderful scent, but keep dogs away from them)

Do not pile mulch against the stems of plants or tree trunks. Leave a five-centimetre gap around the base to prevent rot.

Creating shade

A garden without shade is unusable between eleven and four on a hot July day. There are plenty of solutions depending on your budget and style.

Shade sails and canopies

A three-by-four-metre shade sail costs around forty to sixty pounds and instantly creates a pleasant seating area. Choose a permeable model that allows air through and filters UV. Fix it securely because summer storms arrive quickly.

Climbers on a pergola

A pergola clothed in climbing plants is the most beautiful shade solution. Wisteria, grape vine, honeysuckle or a kiwi will create a natural leaf canopy. But this is a long-term investment: allow two to three years before the planting provides meaningful shade.

Parasols

The classic option. Choose a heavy, tiltable model with a solid base. Lightweight parasols blow over in the first gust and are a source of constant frustration.

Maintaining outdoor furniture

Before summer starts in earnest, your garden furniture deserves attention:

• Hardwood furniture (teak, acacia): sand lightly and apply a coat of hardwood oil
• Metal furniture: check for rust, sand any rusty spots and treat with anti-rust paint
• Plastic furniture: a scrub with warm soapy water removes algae and grime
• Cushions: wash the covers or replace them if they have faded over winter

Store cushions in a weatherproof box near the seating area. It saves carrying them indoors every evening.

Preparing the BBQ area

The barbecue deserves a dedicated spot. Choose a flat, heat-resistant surface. Paving slabs or gravel are ideal, grass is not: it scorches and you end up with an ugly bare patch for the rest of the year.

Service your barbecue before the season starts. Clean the grates, replace worn parts and check the gas connection if you have a gas model. Keep a fire blanket within reach.

Trimming hedges and checking privacy screens

Nobody wants to spend the summer feeling overlooked. Late spring and early summer are the best times to clip hedges into a dense, impenetrable screen.

• Beech: clip now for the first time, then again in August if needed
• Privet: grows fast, clip every six weeks
• Laurel: use secateurs rather than hedge trimmers to avoid shredding the large leaves
• Conifers: trim only the green growth, never cut into old brown wood

Check your fences and screens too. Replace broken panels, secure loose posts and apply a fresh coat of stain if the wood looks tired.

Planting summer bedding

Now is the time to fill the last gaps in your borders with summer-flowering plants that handle heat and drought well:

• Lavender: sun-loving, drought-tolerant, adored by bees
• Verbena bonariensis: tall, airy plant that flowers all summer
• Echinacea (coneflower): robust, prolific and brilliant for butterflies
• Perovskia (Russian sage): silvery foliage, blue flowers, loves heat
• Gaura: delicate white or pink blooms that dance in the breeze all season
• Ornamental grasses like Stipa tenuissima or Pennisetum: need little water and glow in the evening sun

Evening lighting

Even in summer, darkness arrives eventually. Good garden lighting extends your outdoor hours and adds atmosphere.

• Solar path lights: cheap, easy to install, no wiring needed
• LED string lights in trees or across the pergola: instant cosiness
• Recessed deck lights: subtle but effective
• Lanterns and candles: classic and atmospheric, but mind the fire risk

Choose lights with a warm white colour temperature (2700 to 3000 Kelvin). Cool white light gives a clinical feel that clashes with a garden setting.

Mosquito-repelling plants

Mosquitoes are the bane of every summer evening. Instead of reaching for chemical sprays, you can plant things that help keep them at bay. No single plant is a magic bullet, but the combination genuinely makes a difference:

• Citronella grass (Cymbopogon): the best-known mosquito deterrent, grow it in pots near seating areas
• Lavender: the scent repels mosquitoes
• Catmint (Nepeta): contains nepetalactone, which research suggests is more effective than DEET
• Rosemary: throw a sprig on the barbecue to release its scent
• Lemongrass and citrus plants: in pots on the terrace

Combine the plants with a few citronella candles and you have a much more pleasant seating area after dark.

Preventing heat stress in plants

When temperatures climb above thirty degrees, many plants struggle. Learn to read the signs:

• Wilting leaves during the day that recover by evening: this is normal; the plant is protecting itself
• Wilting leaves that do not recover: genuine water shortage
• Scorched leaf edges: too much direct sun on sensitive plants

What you can do:

• Water early in the morning, never in the middle of the day
• Move potted plants to partial shade on the hottest days
• Hang a light shade cloth over vulnerable containers
• Do not prune during heatwaves as it adds stress

Preparing containers for holiday watering

Going on holiday? Your pots and containers need to survive two weeks without you. Here are the strategies:

• Group all pots together in a shady spot. This reduces evaporation and pots shelter each other
• Water deeply the day before you leave and mulch the surface of each pot
• Drip system with timer: the most reliable solution
• DIY bottle dripper: pierce a tiny hole in the cap of a full plastic bottle and invert it into the pot. It releases water slowly over days
• Ollas or terracotta watering spikes: porous clay pots or cones you bury in the soil and fill with water. They release moisture gradually to surrounding roots
• Ask a neighbour: the oldest and most reliable method. Leave clear instructions about what needs water and what does not

Establishing a watering schedule

Not every plant needs the same amount of water, and not everything needs it daily. A sensible watering schedule saves water and keeps plants healthier:

• Lawn: let the grass grow slightly longer in dry spells; short grass dries out faster. Water deeply twice a week at most
• Perennial borders: a thorough soak twice a week beats a light sprinkle every day
• Vegetable garden: check daily, especially tomatoes and courgettes which are thirsty crops
• Containers: daily in warm weather, twice daily in extreme heat
• Newly planted trees and shrubs: twenty litres per tree per week for the first two summers

The result: a garden you enjoy all summer

Work through this checklist and you end up with a garden that can handle whatever summer throws at it. No parched borders, no toppled parasols, no mosquito siege. Just a place where you collapse into your garden chair after a long day, drink in hand, and think: this is exactly what I needed.
