Winter koi pond food with a wheatgerm formula is specifically designed for feeding koi and goldfish when water temperatures drop below 10°C. The highly digestible pellets float on the surface, allowing easy feeding and uneaten food removal. A vital seasonal staple for every UK pond keeper.
Why Wheatgerm Matters in Cold Water
As pond temperatures fall through autumn and into winter, your koi's metabolism slows dramatically. A fish's digestive system requires warmth to process proteins efficiently. Standard high-protein summer foods fed in cold water can pass through undigested, rotting in the gut and causing serious internal complications — even death. Wheatgerm is a low-protein, highly digestible carbohydrate source that koi can process safely at temperatures as low as 4°C.
The Cold Water Advantage
Our winter pond food is formulated with wheatgerm as the primary ingredient, supported by spirulina for natural colour enhancement and immune support. The floating pellet format lets you monitor exactly how much your fish are consuming, allowing you to remove uneaten food before it breaks down and spikes ammonia levels in your increasingly sluggish biological filter.

Below 4°C: Stop feeding entirely — fish are dormant
Frequently Asked Questions
When should I switch to wheatgerm pond food?
Switch to wheatgerm food when your pond thermometer reads consistently below 12–14°C — typically in October across most of the UK. This transition allows your koi's digestive system to adapt gradually before the coldest winter months arrive.
Can I feed koi in winter?
Yes, but only with appropriate cold-water food and only when temperatures are above 4°C. Feed small amounts on mild days and remove any uneaten pellets after 5 minutes. Never feed koi in freezing conditions.
Why does spirulina help in winter?
Spirulina is a natural algae rich in beta-carotene and antioxidants. During winter, when koi immunity is naturally lower, spirulina provides immune support and helps maintain vibrant colour through the cold months.
What size pellet is best for koi?
For koi over 30cm (12 inches), a medium or large pellet works best. Smaller koi and goldfish benefit from mini pellets. Our standard pellet size suits most adult koi in typical UK garden ponds.
How long does a bag last?
A 1kg bag typically lasts one koi keeper through autumn (6–8 weeks of reduced feeding). The 2.5kg bag suits larger ponds with multiple fish through the full autumn-to-spring transition period.
