Best Ways to Store Garden Tools During Minnesota Winters
Winter in Minnesota is long, cold, and often wet. Those conditions are tough on garden tools: metal rusts, wooden handles crack, power equipment degrades, and hoses and watering systems can freeze and split. Proper winter storage preserves tools, reduces spring maintenance, and saves money by extending the useful life of expensive equipment. This article provides practical, region-specific strategies for storing garden tools through Minnesota winters, with concrete steps, materials to use, temperature and humidity considerations, and a clear seasonal checklist you can follow.
Understand Minnesota winter hazards for tools
Minnesota winters include prolonged below-freezing temperatures, heavy snow, freeze-thaw cycles, and periods of high humidity in enclosed spaces. These factors create three primary threats to garden tools:
-
Corrosion and rust on metal surfaces.
-
Drying, cracking, or splitting of untreated wooden handles.
-
Damage to batteries, electronics, and fuel systems in power tools.
Recognizing these hazards helps you choose storage methods that address temperature control, moisture control, and mechanical protection.
Clean and maintain every tool before storage
One of the single most important steps in winterizing tools is a thorough cleaning and basic maintenance. Dirt, plant sap, and moisture left on tools accelerate rust and wood damage.
Start with these concrete steps:
- Remove soil and plant debris.
Wash off dirt with a stiff brush and water. For stubborn soil, use a putty knife on pry points. Allow tools to dry fully before continuing. Do not put dirty tools into enclosed storage.
- Remove rust and old lubrication.
Use a wire brush, sandpaper, or a stiff scrubbing pad to remove rust flakes. For small patches of rust, steel wool or a rust eraser works well. After cleaning, apply a light coat of oil or WD-40 alternative to metal surfaces to inhibit new rust.
- Sharp edges and moving parts.
Sharpen blades (pruners, shears, shovels) and lubricate pivot points with a drop of machine oil. Tighten loose screws and replace damaged bolts.
- Treat wooden handles.
Sand rough or splintered wood lightly and apply boiled linseed oil or a penetrating wood finish. This maintains moisture balance and prevents winter drying and cracking.
- Drain and stabilize fuel for gas equipment.
If you store gas-powered mowers, trimmers, or blowers indoors, run the engine until it is dry of fuel, or add a fuel stabilizer and run the engine long enough for the stabilizer to circulate. Store gasoline in approved containers in a well-ventilated, code-compliant area, not in living spaces.
Complete these steps several days before storage to ensure everything is dry and properly treated.
Choose the right storage location
Location choices in Minnesota fall into several categories: heated indoor storage, unheated garages and sheds, basements, and organized outdoor shelters. Each has trade-offs.
Heated indoor storage (best)
Storing tools in a heated garage or workshop provides the most protection. Stable above-freezing temperatures prevent freeze-thaw cycles that can damage power tool batteries and cause condensation. Ideal conditions are cool (40-60 F), dry, and well-ventilated.
Advantages:
-
Batteries and fuel-handling equipment stay within safe temperature ranges.
-
Reduced condensation and rust.
Disadvantages:
- Heating cost if you actively heat the storage space.
If you have a heated space, avoid placing tools right next to a heat source where extreme dryness could harm wooden handles. Use humidity control if needed (see next section).
Unheated garages and sheds (common)
These are typical in Minnesota but require extra precautions. Unheated spaces undergo wide temperature swings and can trap moisture.
Strategies for unheated spaces:
-
Elevate tools off concrete floors to reduce dampness transfer: use slatted shelving or pegboards attached to studs.
-
Insulate exposed walls to moderate temperature swings if feasible.
-
Use desiccant packets or a small electric dehumidifier rated for garage use to reduce interior humidity.
-
Keep tools in sealed cabinets or plastic bins for small hand tools to block dust and moisture.
Basements and crawl spaces
Basements are often better than unheated garages because temperatures are more stable. However, basements can be humid. Use a dehumidifier if basement relative humidity exceeds 50 percent. Store metal tools in sealed cabinets or on pegboards at least a foot off the floor to avoid flood risk.
Control moisture and humidity
Rust is driven by presence of moisture and oxygen. In Minnesota winters, condensation is a major problem when cold metal is brought into a warm, humid space.
Practical moisture-control tactics:
-
Allow tools to reach room temperature before sealing them in plastic. This avoids condensation inside containers.
-
Use desiccant packs (silica gel) in tool chests and storage bins. Replace or recharge them seasonally.
-
Consider using a small appliance dehumidifier in enclosed garages or sheds. Aim to keep relative humidity below 50 percent.
-
Use breathable storage: avoid wrapping tools tightly in plastic for long periods. For wooden tools, breathable covers are better; for small metal tools, airtight plastic bins with desiccant work well.
-
If you have many metal tools, hang them on an open pegboard rather than stacking on shelves, which improves air circulation and reduces trapped moisture.
Organize and hang tools to prevent damage
How you store tools affects longevity and accessibility. Hanging and organizing tools prevents bending, warping, and accidental damage.
Best practices:
-
Use a treated wood backboard or metal slotted panels to mount hangers. Keep heavy items on lower hooks.
-
Hang long handled tools (rakes, shovels, hoes) off the floor with heavy-duty wall hooks or a vertical tool rack. This prevents handle sag and cracking.
-
Store sharp tools (saws, shears) with blade guards or in a locked cabinet to protect both the blade and people.
-
Group similar tools together: pruning tools, digging tools, hand tools, power tools. Label shelves and bins.
-
For small hand tools, use a chest with removable trays and silica gel packets. Clean tools before storing to avoid trapping organic debris.
Winter storage for power tools and batteries
Power tools need special attention. Freezing can damage lithium-ion battery packs and internal sealants, and fuel can gum engines.
Guidelines:
-
Remove batteries from cordless tools. Store batteries in a cool, dry place above freezing but preferably at moderate temperatures (40-60 F). Avoid storage below freezing; many battery manufacturers advise storing at or above 32 F.
-
Charge batteries to approximately 40-60 percent before long-term storage, not 100 percent, unless manufacturer instructions state otherwise. Check manufacturer recommendations when available.
-
Store batteries off concrete and on insulated shelving if possible.
-
For gas engines, either drain the fuel system completely or add a fuel stabilizer and run the engine so treated fuel circulates. Change engine oil and spark plugs if due.
-
Clean and dry air filters; consider replacing foam filters if heavily soiled.
Protect hoses, sprinklers, and irrigation systems
Hoses and drip irrigation lines can split when water freezes. Winter prep is straightforward but essential.
Steps:
-
Drain hoses completely and coil them loosely to avoid kinks. Store hoses indoors or in a heated garage. If you must leave hoses outdoors, disconnect and use frost-free hose bibs and insulate exposed spigots.
-
Blow out irrigation systems before the first deep freeze, using compressed air at recommended pressure to clear water from lines. If unsure, hire a professional to avoid damage.
-
Store sprinkler heads and fittings in labeled containers to avoid loss and to keep small parts dry.
Prevent pests and rodents
Rodents seek shelter in winter and can chew handles, wires, and insulation.
Preventive measures:
-
Seal cracks in storage structures and block gaps under garage doors.
-
Store power tools and wiring in sealed plastic bins with tight lids.
-
Use rodent deterrents: peppermint oil-soaked cotton in corners, snap traps placed away from children, or professional pest control for heavy infestations.
-
Avoid leaving food or birdseed in the same storage area unless it is well sealed and rodent-proof.
