Hebe Dieback in Moray, Scotland: Extended Cold + Fungus

Moray, Scotland gardener: all hebes died back over two winters; many dead. Usually hardy—disease or weather?

Expert "Coach Dave" View

• Hebes (Veronica/salicifolia) are hardy but have weaknesses.
• Extended cold → massive fungus.
• Larger leaves = more frost vulnerable.
• Prune hard + fungicide (Mancozeb) to stimulate dense regrowth.

Hebe Culture Facts

• Well-drained, slightly acidic soil.
• Great for landscape/containers.
• Stress in humidity; love sun/wind; tolerate cruel winds.
• Attract butterflies when flowering.
• Easy from seed, softwood cuttings, layering.

Cold-induced fungal decline is the culprit. Hard pruning + fungicide = recovery path.
