Environmental Needs
- Climate: {"temperatureRange":"5–30°C"}
- Hardiness: {"zones":"4–8"}
- Misting: rarely required, only if ambient humidity is very low

- Soil Type: Well-draining, loamy soil with added organic matter; tolerates poor soil but thrives with enrichment.
Maintenance Level
- Maintenance Level: low
- Toughness Level: moderate
- Pruning Frequency: Deadhead flowers weekly during blooming; shape prune in early spring before new growth begins.
- Pruning Intensity: Light to moderate; avoid heavy pruning unless necessary to control size or shape.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may produce fewer flowers.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight if moving from shade; protect from harsh afternoon sun in hot climates; ensure good air circulation to prevent sunburn or fungal issues.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plants weekly for even light exposure; use shade cloth in extreme heat; avoid placing in drafty areas.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering to prevent fungal issues.
Soil
well-drained, moderately fertile soil
pH: Slightly alkaline to neutral (pH 6.5–7.5).
Ensure soil is not compacted; use mulch to retain moisture and suppress weeds; test pH if issues arise.
Temperature
Prefers moderate temperatures (60–75°F or 15–24°C); can tolerate cooler conditions but may go dormant in winter.
Avoid sudden temperature fluctuations; protect from frost; maintain consistent temperatures for optimal growth.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer after watering to prevent root burn; stop fertilizing when the plant is dormant; use organic options like compost tea for gentle feeding.
Propagation
Methods
Stem cuttings or seed; stem cuttings are faster and more reliable for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting just below a leaf node.
- Remove lower leaves.
- Dip in rooting hormone (if using).
- Plant in moist medium.
- Keep humid and moist until roots form.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F or 21–24°C), humid environment with bright, indirect light; protect from direct sun and drafts.
Medium
Well-draining potting mix (e.g., peat moss, perlite, and sand); can also root in water initially.
Hormone
Rooting hormone is optional but recommended for faster root development.
Timeline
Roots may develop in 2–4 weeks; new growth typically appears within 6–8 weeks.
Tools Needed
Sharp pruners, rooting hormone, small pots, well-draining medium, plastic bag or propagator for humidity.
Quick Tips
Use healthy, non-flowering stems for cuttings; maintain consistent moisture without waterlogging; provide gentle bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips to encourage branching; cut stems just above a leaf node or bud; remove dead or crossing branches.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and prolong flowering; remove spent flowers to promote reblooming.
Tools
Sharp bypass pruners, clean scissors, gloves.
Checklist
Disinfect tools before use; prune in early morning or evening; remove only necessary parts; avoid over-pruning.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure the new pot has drainage holes.
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the container; beneficial for container-grown plants to refresh soil and provide space.
Checklist
Choose the right pot size; prepare fresh soil mix; handle roots carefully; water and place in appropriate light after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at the base; ensure proper drainage; adjust frequency based on season and weather.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; water early in the morning to minimize evaporation and fungal growth; allow excess water to drain away to prevent waterlogging.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add compost or well-rotted manure for fertility; mix in perlite or sand for drainage; avoid heavy clay soils.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat; leaf drop or browning in cold stress.
Cold Stress
Low temperatures can slow growth or cause leaf damage; prolonged cold may lead to dormancy or death if not protected.
Solution: Mulch around the base to insulate roots; move potted plants indoors or to a sheltered location; avoid overwatering in cold conditions.
Hot Stress
Excessive heat can cause wilting, flower drop, or leaf scorch; rapid water loss may stress the plant.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer label for NPK ratio; dilute correctly; apply to moist soil; avoid contact with foliage.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring to early fall); avoid fertilizing in winter.
Common Problems & Solutions
Toxicity Warning
Cats
Non-toxicMalva sylvestris is not considered toxic to cats. The plant is generally safe for feline consumption, though ingestion of large amounts may lead to mild gastrointestinal discomfort due to its fibrous and mucilaginous properties.
