Care Guide
Digitalis Lutea requires moderate care and attention to grow successfully. Here are some tips to help you care for your Straw foxglove:
Water: The plant needs to be watered regularly to keep the soil moist but not waterlogged. Overwatering can cause root rot, so it’s important to allow the soil to dry out slightly between waterings.
Fertilization: Apply a slow-release fertilizer in the spring to encourage growth and bloom. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
Soil: Digitalis Lutea prefers well-draining soil that is slightly acidic to neutral. Amend the soil with organic matter, such as compost or peat moss, to improve its texture and fertility.
Sunlight: The plant needs full to partial sunlight to thrive. It can tolerate some shade, but too much shade can reduce flowering.
Hardiness Zones: Digitalis Lutea is hardy in USDA zones 4-8.
