Winter is the season for slow, gentle feeding. No sudden nutrient highs — just steady enrichment that worms and microbes can work on quietly over the cold months
Bare soil is vulnerable soil. Rain compacts it, frost cracks it, and wind strips away its nutrients.
A mulch layer protects it through the harshest months. Ideal winter mulches:
Leaf mould

If you’ve been caught out with empty beds, don’t let them sit bare.
Sow hardy green manures like:
Worms don’t get enough credit. They aerate, decompact, digest, fertilise, and transform your soil in ways no tool ever could.
To support them now:

Even though growth slows, your soil biology still hums away quietly. You can keep it fed with gentle, homemade brews.
Comfrey Tea
Rich in potassium and micronutrients — ideal for soil biology rather than active plants in winter.
Nettle Tea
High in nitrogen and iron. Brew indoors and apply lightly only on mild days when soil isn’t frozen.
Seaweed Tea
A brilliant winter tonic for soil microbes and trace minerals.
Use sparingly — just enough to keep soil life ticking over.
If you haven’t got mulch, compost, or green manure, cover the soil:

Living roots keep the soil ecosystem active. You can still plant hardy crops now, especially under protection:
Avoid:

As the allotment sleeps, soil care becomes your most important job.
While the surface looks still, an entire micro-world is working beneath — microbes digesting organic matter, fungi weaving networks, worms pulling in leaves, nutrients locking into structure, and the soil preparing for spring.
Winter is the soil’s reset button. What you do now determines what your crops can achieve later.
Give it food.
Give it cover.
Give it life.
Give it rest.
Come spring, your veg will repay you.
