Caring for a Potted Outdoor Yucca in the UK

Dyrck's 5–6 year outdoor potted yucca in the UK had yellow lower leaves. Winters wet, rarely below freezing.

Diagnosis

• Yellow lower leaves: normal aging (yuccas shed old leaves).
• Pot-bound? Likely after 5+ years—check roots.

Care

• Water weekly when dry; dry out between.
• Balanced fertilizer at ¼ strength, several times in growing season.
• No water below 50°F (10°C)—cold + wet = rot.
• Repot if root-bound; use gritty mix.

Species may be cold-hardier than typical.
