Watering Needs
Crassula 'Tom Thumb' is drought-tolerant, like most succulents, and requires minimal watering. For a 4-5 inch pot, water around 1/8 cup every 2-3 weeks, ensuring the soil is completely dry between waterings. During its dormant period in the summer, reduce watering significantly.
Overwatering can lead to root rot, so it's important to follow the proper watering technique to avoid any issues.
Light Requirements
Crassula 'Tom Thumb' loves bright light and thrives best in full sun, but it can tolerate partial shade. If grown indoors, place it in a bright, sunny window. For those with less access to natural sunlight, consider using a grow-light for indoor succulents to ensure it receives the light it needs to maintain its compact and healthy growth.
Fertilizing Schedule
During its growing season (spring to fall), Crassula 'Tom Thumb' benefits from monthly feeding. For a 4-5 inch pot, use 1/8 teaspoon of a balanced NPK fertilizer, diluted to half-strength. This will help the plant stay vibrant and grow steadily without becoming leggy. Avoid fertilizing during its dormancy in summer to prevent weak growth.
