Troubleshooting
Victoria Rhubarb problems — and how to fix them
Victoria Rhubarb (Rheum × hybridum 'Victoria') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot in wet soil
Waterlogged ground or manure heaped on the crown causes the crown to rot and collapse. Plant in well-drained soil with the crown bud just at the surface and keep mulch off the centre.
Premature flowering (bolting)
Stress, heat or an ageing crown triggers tall flower spikes that drain the plant. Cut flowering stems out at the base as soon as they appear to keep energy in the stalks.
Over-harvesting young crowns
Pulling too many stalks, or any in the first year, weakens the plant. Harvest lightly in year two and never strip more than about half the stalks at once.
Toxic leaves
The leaf blades contain harmful oxalic acid and must never be eaten by people or pets; compost or discard them and harvest only the stalks.
