August in the garden is a month of two halves. It’s a time to sit back and enjoy the results of your hard work, but also the moment for late-summer jobs that prepare for a brilliant autumn and an even better spring.
Here at Love Plants in Shrewsbury, we know that Shropshire gardens have their own unique character. From the rolling hills near Church Stretton to the sheltered Severn Valley, conditions can change in a heartbeat. This guide is tailored to help you make the most of August, whatever the weather brings.
In a Rush? Here’s Your August Checklist
- Water wisely: Prioritise new plants, pots, and veg. Water in the early morning or evening.
- Keep deadheading: Snip faded flowers from roses, bedding, and perennials to keep blooms coming.
- Harvest often: Pick fruit and veg little and often to keep plants productive.
- Prune key shrubs: Summer prune Wisteria and trained apple and pear trees.
- Look after your lawn: Mow higher and less often if dry. A golden lawn will recover.
- Plan for spring: Start ordering spring-flowering bulbs.
What This Means for Your Garden in Shropshire
- Water management: Shropshire’s “sunshine and showers” means you must be smart. After rain, check pots for dry compost under leaf canopies. Apply a 5 cm mulch of bark or compost to lock in moisture and suppress weeds.
- Blight risk: Warm days and damp nights increase the risk of potato and tomato blight. Improve airflow, remove yellow leaves, and stay vigilant.
- Microclimates: In exposed gardens, wind quickly dries soil. In sheltered Severn Valley plots, humidity may increase fungal disease risk. Adjust watering and ventilation accordingly.
August Task Planner
| Task | Best Window | Why It Matters | Quick How-To |
|---|---|---|---|
| Check for active bird nests | Before hedge trimming | Protects wildlife; it is illegal to disturb nesting birds | Look and listen carefully; delay trimming if unsure |
| Summer prune Wisteria | August | Controls vigorous growth and encourages next year’s flowers | Cut back long green shoots to 5–6 leaves from the framework |
| Prune trained fruit trees | August | Keeps shape and promotes fruiting | Prune apples and pears grown as cordons or espaliers |
| Deadhead flowers | All month | Encourages continued flowering into autumn | Remove faded blooms on roses, bedding, and perennials |
| Feed tomatoes, cucumbers & peppers | Weekly | Supports heavy cropping plants | Apply high-potassium liquid feed (e.g., tomato fertiliser) |
| Protect brassicas | All month | Stops cabbage white butterflies laying eggs | Use fine netting over cabbages, kale, and broccoli |
| Sow autumn crops | Early to mid August | Extends harvest into autumn | Sow lettuce, rocket, radishes, or green manure in cleared beds |
Jobs Around the Garden
Trees, Shrubs & Roses
- Carry out summer pruning on Wisteria and trained fruit trees.
- Keep tying in new growth on climbers such as roses and clematis.
- Water newly planted trees and shrubs thoroughly during dry spells.
Beds & Borders
- Continue deadheading to prolong flowering into autumn.
- Cut back tired perennials like hardy geraniums for fresh growth.
- Pro tip: Use lavender clippings to make homemade lavender bags.
The Kitchen Garden
- Harvest beans, courgettes, and tomatoes regularly.
- Feed weekly with high-potash liquid fertiliser.
- Remove tomato side-shoots to direct energy into fruit.
- Protect brassicas with netting from butterflies.
- Sow fast crops such as lettuce, rocket, and radishes, or plant green manures.
Lawn Care
- Raise mower blades and mow less frequently in dry weather.
- Allow lawns to go golden — they will recover naturally with autumn rain.
- Only water newly sown lawns if essential.
Greenhouse & Houseplants
- Ventilate greenhouses and use shading to prevent overheating.
- Damp down greenhouse floors on hot days to increase humidity and deter pests.
- Group pots together on capillary matting if going away.
- Water houseplants more often and feed fortnightly. Move them out of harsh sun to prevent scorch.
Decision Checklist: What to Prioritise
- Heatwave? Water pots and new plants early or late. Pause mowing and heavy digging.
- Wet & warm? Check tomatoes and potatoes for blight. Increase airflow in greenhouses.
- Fruit ripening fast? Prioritise harvesting and preserving. Secure fruit cages against birds.
- Pruning overdue? Trim Wisteria, fruit trees, or lavender this week.

Frequently Asked Questions (FAQs)
How often should I water hanging baskets in an August heatwave?
Water twice daily in hot, dry, or windy conditions — early morning and evening. Check by lifting the basket; if light, it needs soaking.
How do I deadhead roses?
For single roses, cut back to just above the first leaf with five leaflets. For clusters, remove faded flowers and the whole cluster when spent.
When should I stop tall tomato plants from growing?
Towards the end of August, pinch out the top growing tip of cordon tomatoes to focus energy on ripening existing fruit.
How can I stop lettuce bolting in the heat?
Keep soil moist and provide shade during the hottest hours. Shade netting or taller plants casting shadows can help reduce stress.
