Outdoor plant
care guide
From the patio to the garden, care that follows the weather.
Watch the sun, feel the soil and give excess water a way out.
For common outdoor plants in pots, planters and garden beds. Species have individual needs; lawns, aquatic plants and large trees require separate care plans.
Watch the actual sun
Light can change greatly between morning, noon and afternoon.
Let the soil guide you
Even after rain, check whether water reached the roots.
Give rainwater a way out
Keep drainage holes, pot bases and ground drains clear.
GARDEN PLUS · QUICK GUIDE
Outdoor care at a glance
Check the sun and soil, water when needed, then let excess water drain.
Read the text summary
- Check the sun: match the light to the plant.
- Feel the soil: check moisture below the surface.
- Water if needed: soak the root ball slowly.
- Let it drain: empty standing water and keep outlets clear.
In heat, check more often. After rain, check drainage. Before a typhoon, move manageable pots to a safe place early.
01 / SUN & PLACEMENT
Outdoors does not mean
sunny all day.
Observe morning, midday and afternoon light. Awnings, walls, tree canopies and neighbouring buildings all change where the sun reaches.
Match the place to the species. “Outdoor plant” does not mean every plant thrives in all-day exposure.
Reference: RHS: understanding sun and shade
-
Open positions with prolonged sun
Check that the species suits the exposure. West-facing positions and heat-retaining walls can become hotter in the afternoon.
-
Part-day sun or shade
Choose for the light actually available. Some sun-loving plants flower less in shade; avoid moving shade-grown plants straight into harsh sun.
-
Covered patios, eaves and walls
Rain may not reach the pot even when it falls outdoors. Judge both light and moisture at the plant’s actual position.
02 / A NEW ARRIVAL
Newly delivered or planted?
Give it a little extra attention.
-
Check the plant and container
Remove transport packaging and inspect foliage, stems, the root-ball surface and drainage holes. Photograph any broken branches or visible damage.
-
Introduce the new conditions gradually
Find out the plant’s previous light conditions. Let it adjust to stronger sun and wind rather than moving directly from shelter into full exposure.
-
Check the original root ball
New roots have not yet fully reached the surrounding soil. Check both the original root ball and nearby soil: damp ground does not guarantee moist roots.
03 / WATER AT THE ROOTS
Does it need water today?
Feel the soil first.
Heat, wind and small pots can speed up drying. Cloudy weather or persistent rain may do the opposite. Check more often when conditions change, then water as needed.
-
Check below the surface
Move mulch aside and feel the soil below. Small pots can be judged partly by weight; do not judge a deep container by its surface alone.
-
Deliver water slowly to the roots
When needed, water evenly across the soil and allow it to soak into the root ball. For pots, stop as water begins to drain. Avoid merely wetting leaves or giving tiny daily splashes.
-
Prefer mornings, but respond to need
Morning watering usually reduces evaporation. If a plant is clearly short of water later in the day and the soil is dry, water it rather than waiting until tomorrow.
Check even after rain. Dense foliage, a roof or a short shower may leave the root ball dry.

Pots and garden beds need different care
Pots and planters
Limited root space makes regular moisture checks and watering important. Large and small pots, terracotta and plastic can all dry at different speeds.
Plants in the ground
Check the original root ball and nearby soil of new plantings. Once established, water according to species, soil, rainfall and dry conditions rather than following a container schedule.
04 / AFTER THE RAIN
After rain,
follow the water.
Too much water can also harm roots. Good outdoor care includes letting excess water leave the container and planting area.
-
Check the pot can drain
Open drainage outlets or remove plugs according to the manufacturer’s instructions. Ordinary soil-grown plants exposed to rain should not collect water in sealed outer pots.
-
Check underneath and empty saucers
Remove standing water and check for blocked outlets. Use stable, load-appropriate pot feet if needed. Manage overflow in reservoir planters according to their instructions.
-
Keep the drainage route clear
Remove leaves and debris from ground drains. If a planter or garden bed stays waterlogged, investigate the cause and pause unnecessary irrigation.

05 / WEATHER READINESS
Prepare for sun, rain & typhoons
Adjust care as the weather changes. Complete wind precautions before strong winds arrive.
Heat and drying winds
Check soil more often and watch container heat and leaf condition. Adjust placement if the species needs it; drooping alone is not a reason to keep watering.
Persistent rain
Check pot bases, saucers, planters and ground drains. Adjust automatic irrigation to rainfall and soil moisture instead of running an unchanged schedule.
Before a typhoon
Follow Observatory updates. Move manageable pots and loose items to safe locations early and clear drains. Keep pots off railings and exposed ledges. Stay safely indoors during strong winds rather than going out to rescue plants.
A heavy pot is not automatically wind-safe. Arrange appropriate help to assess large containers, trellises and trees in advance; avoid risky last-minute moves.

06 / EVERYDAY CARE
Feeding, pruning & a closer look
Reference: RHS: ongoing container care
Reference: RHS: pruning basics
Feed according to growth
Feed healthy, actively growing plants according to species and product instructions. Check for existing slow-release fertiliser before adding more. Address dry soil, waterlogging or decline before feeding.
Identify the plant before pruning
Remove dead leaves and spent flowers as appropriate. Flower buds develop at different times: avoid pruning every flowering plant hard in the same season. Leave large branches and work at height to suitable professionals.
Look at leaf undersides and new shoots
Watch for insects, eggs and unusual marks around tender growth and stem joints. Identify the cause before treatment. If using a pesticide, follow its label and approved plant uses.
07 / READ THE SIGNS
Something has changed.
What should you check?
Look at recent weather, sunlight, moisture and drainage together. They tell you more than one leaf on its own.
Reference: RHS: waterlogging and roots
It has rained. Does the plant still need water?
Check the root ball. Roofs or foliage may have intercepted rain, or a shower may only have wet the surface. If soil is still moist, there is no need to add more.
Drooping at midday: is it thirsty?
Feel the soil and assess exposure first. Water slowly if dry; if still wet, heat or root problems may be involved. Check for recovery when cooler and investigate persistent wilting.
Yellow leaves after rain, and soil that stays wet?
Check drainage holes, saucers, outer pots and ground drainage. Stop unnecessary watering. Ask for advice if there is an unusual smell, soft stems or continuing leaf drop.
Plenty of leaves, but few flowers?
Check the species’ flowering season, actual sunlight, pruning timing and feeding. Plants do not all flower year-round, and extra fertiliser is not a universal fix.
Can I give twice as much water before going away?
Do not store water by leaving roots submerged. Water as needed, arrange checks or test a suitable irrigation system before leaving. Different plants and containers may need different amounts.
