Treatment and Prevention

🌊 Adjusting watering practices

Proper watering is crucial for the health of your Pittosporum 'Tom Thumb'. Start by checking the soil moisture to ensure your plant is neither overwatered nor underwatered.

How to check soil moisture

1. Insert your finger 1-2 inches into the soil.
2. Assess the moisture level: if it feels dry, it's time to water; if it's moist, wait a bit longer.
