Keeping outdoor plants looking their best isn’t just about watering now and then — it’s about creating the right environment for strong, natural growth. Whether you’re caring for shrubs, flowers, or potted patio plants, this guide covers the best ways to keep your outdoor plants healthy all year round.
1. Water Wisely — Not Too Much, Not Too Little
It sounds obvious, but watering is the number one mistake many gardeners make. Outdoor plants thrive when watered deeply but less often, which encourages deep root growth.
✅ Top tip:
- Water early morning or evening to reduce evaporation
- Use mulch to retain soil moisture
- Stick your finger into the soil — if it’s dry a few inches down, it’s time to water
2. Feed Your Plants With the Right Nutrients
Just like us, plants need food! Apply a balanced, slow-release fertiliser in spring and summer to give them essential nutrients. Look for feeds high in nitrogen for leafy plants, and potassium-rich ones for flowers and fruiting varieties.
🌼 Pro tip:
Don’t over-fertilise — it can burn roots and harm plant health. Always follow instructions on the label.
3. Choose the Right Location
Even the healthiest plant will struggle if it’s in the wrong spot. Pay attention to light, shade, soil type, and wind exposure.
☀️ Check plant labels for sun/shade requirements before planting.
💨 Shelter delicate plants from strong winds with hedges or fencing.
🌱 Use raised beds or compost to improve poor soil.
4. Prune & Deadhead Regularly
Pruning encourages bushier growth and removes weak or diseased stems. Deadheading (removing faded flowers) helps plants focus energy on producing new blooms.
🪚 Best times to prune:
- Spring: Light shaping and frost damage removal
- Summer: Encourage flowers and new growth
- Autumn: Remove dead wood and prep for winter
5. Keep an Eye Out for Pests & Diseases
Common UK garden pests like aphids, slugs, vine weevils, and fungal diseases can quickly weaken or kill outdoor plants.
🔍 Prevention is better than cure:
- Inspect plants weekly
- Encourage natural predators like ladybirds
- Use organic pest control methods when needed
- Remove infected leaves to stop spread
6. Mulch for Moisture, Protection & Nutrients
Mulching your borders with bark, compost or leaf mould:
- Locks in soil moisture
- Suppresses weeds
- Regulates temperature
- Adds organic matter over time
Apply mulch around the base of your plants in spring and autumn for year-round benefit.
7. Protect Plants From Extreme Weather
Outdoor plants in the UK face everything from summer heatwaves to winter frosts. Protect them with:
- Fleece or cloches in cold weather
- Shade netting during extreme sun
- Windbreaks in exposed gardens
- Proper drainage to avoid root rot in heavy rain
