How to Care for Gerrardanthus Macrorhizus 'Bigfoot'

Jul 31, 2026

Gerrardanthus Macrorhizus 'Bigfoot' is grown for its swollen base and vining growth. This plant grows best in warm indoor temperatures with a fast-draining mix with added pumice or perlite, average household humidity, and medium to bright indirect light.

Water every 1-2 weeks, allowing soil to dry out half way down between waterings. Providing proper drainage and airflow will help reduce the risk of root problems and leaf stress. Monitor the plant for a soft base, yellowing vines, or dark roots. With stable indoor conditions and regular care, Gerrardanthus Macrorhizus 'Bigfoot' can continue growing well over time.

Water Requirements

Water every 1-2 weeks, allowing soil to dry out half way down between waterings. Expect to water more often in brighter light and less often in lower light. Gerrardanthus Macrorhizus 'Bigfoot' benefits from extra humidity and should not sit in soggy soil.

Soil Requirements

Humidity & Temperature
