Companion Planting
Rosemary
ThymeToxicity
Contains eugenol and essential oils; ingestion may cause vomiting, diarrhea, and loss of appetite in pets. Leaves are safe for humans when used as a culinary herb but whole leaves should not be eaten due to choking or obstruction risk.
Planting Tips
1 cm of water per m² equals 10 liters. Use the Watering Calculator for exact amounts.
Care Tip: Prune regularly to maintain shape; shelter from cold winds in winter as it is hardy only to about -10 °C (USDA zone 8).
Common Pests
Bay Sucker (Trioza alacris)
Symptoms: Yellowing and thickening of leaf tissue, curled leaf margins, leaves turning brown and dropping.
Treatment: Remove and destroy affected leaves; apply insecticidal soap or neem oil in spring when nymphs are active.
Prevention: Inspect new growth regularly in spring; encourage natural predators and ensure good air circulation.
Scale Insects
Symptoms: Small brown or white bumps on stems and leaf undersides; sticky honeydew residue and sooty mold on foliage.
Treatment: Wipe off with a cloth dipped in rubbing alcohol or spray with horticultural oil during the dormant season.
Prevention: Avoid over-fertilizing with nitrogen; monitor plants regularly and remove heavily infested branches.
Aphids
Symptoms: Clusters of small green or black insects on new growth; curled, distorted leaves and sticky honeydew.
Treatment: Spray with a strong jet of water or apply insecticidal soap; introduce ladybugs as biological control.
Prevention: Encourage beneficial insects; avoid excessive nitrogen fertilization that promotes soft new growth.
Common Diseases
Phytophthora Root Rot
Symptoms: Wilting despite adequate watering, yellowing leaves, darkened and mushy roots, stunted growth.
Treatment: Remove affected roots, repot in fresh well-draining soil; apply a phosphonate-based fungicide.
Prevention: Ensure excellent drainage; avoid overwatering and do not let containers sit in standing water.
Powdery Mildew
Symptoms: White powdery coating on leaf surfaces, leaf distortion, and premature defoliation.
Treatment: Remove affected foliage; apply sulfur-based or potassium bicarbonate fungicide sprays.
Prevention: Provide good air circulation through pruning; avoid overhead watering and densely shaded locations.
Anthracnose
Symptoms: Sunken gray or brown patches on leaves and stems; leaves may develop dark spots and drop prematurely.
Treatment: Prune and destroy infected plant parts; apply copper-based fungicide during wet weather.
Prevention: Remove fallen debris around the base; ensure adequate spacing and air flow between plants.
