Reviving Drought-Stressed Azalea in Scotland: Repot or Replace?

Your potted Azalea japonica in Glasgow with fully browned leaves after a hot, dry summer is likely dormant, not dead — but recovery is uncertain. Azaleas have a survival mechanism: they sacrifice foliage to preserve the root crown and latent buds.

Assessment Steps

1. Scratch test: Nick bark on several branches. Green = alive; brown/tan = dead
2. Bend test: Flex pencil-thick branches. Supple = alive; snaps = dead
3. Root check: Tip out of pot. White, firm roots = alive; brown, mushy = dead

If Alive (Green Tissue Found)

1. Repot immediately: Erciacious compost (peat-free) + 20% perlite/grit
2. Prune dead wood: Cut back to green tissue
3. Water regime: Rainwater only (tap water too alkaline); keep evenly moist
4. Location: Dappled shade, sheltered from wind; no afternoon sun
5. Feed: Erciacious liquid feed at ¼ strength monthly April-Sept
6. Patience: May not show growth until next spring

If Mostly Dead / Replacement Case

• Replace this autumn (Sept-Oct) — best establishment window
• Choose compact cultivar: 'Geisha Orange', 'Kirin', 'Hino Crimson'
• Use large pot (min 40cm) with erciacious compost
• Install drip irrigation or self-watering spike for consistency

Scottish Climate Specifics

• Glasgow: Zone 8b-9a, but cool summers, wet winters
• Azaleas prefer ground planting — consider border spot with erciacious soil
• Winter wet is bigger threat than summer dry — ensure perfect drainage

Wait 2-3 weeks after repotting/pruning. If no basal swellings appear, replace. Life's too short for maybe-plants.
