Winter garden needs
Tuck your garden in properly:
• Protect the soil from compaction and erosion
• Reduce nutrient loss from leaching
• Suppress weeds• Replenish organic ma#er• Improve soil structure

Microorganisms are happy• Symbiotic
relationships are maintained
You are happy• Much easier to work
in the spring
When soil is happy...

Soil protection
Cover crop/green manure• Loosens and aerates the soil• Adds organic ma#er and nutrients• Enhances soil microbial activity• Improves soil structure
Lasagna gardening/sheet mulching• Easy way to prep new ground for spring
Tuesday, January 31, 2012
Cover crop strategy
Mix & match• Tall, deep-rooted structural crop
+ N-"xing legume• Suggestions: hairy vetch and
winter rye, crimson clover
Plant ASAP• Give it time to grow before frost
Chop up and dig in before maturity• Otherwise it could become weedy

Sheet mulching instructions
Do it early• Give the process enough time to work
Lay it thick• Loosen soil & remove noxious weeds• Lay newspaper or cardboard• Build in ~1 inch layers of alternating “browns” and
“greens”• Put a layer of dirt (compost or garden soil) on top

Final notes
• Remember: Your primary goal is soil protection and nutrient retention through the rainy months
• If you don’t cover crop or sheet mulch, at least cover vacant beds with straw or leaves
• Fall is a good time to add lime to acidic soils, and a good time to add slow-release organic fertilizers
• And you could still grow some food through the winter...
