Costco’s lawn and garden department changes throughout the year as seasonal merchandise moves in and out of warehouses. During these transitions, certain outdoor products may receive markdowns as Costco makes room for incoming inventory. Clearance activity can vary significantly by warehouse, region, product type, and remaining stock.
Costco's warehouse model depends heavily on rotating inventory. Seasonal merchandise is particularly affected because demand changes throughout the year.
Spring and summer typically bring more lawn equipment, patio furniture, planters, gardening tools, outdoor lighting, and recreational products. As the season changes, warehouse space can shift toward fall and winter merchandise.
Clearance markdowns can happen for several reasons:
Costco's website currently highlights products marked “While Supplies Last,” reinforcing the importance of inventory timing when shopping seasonal merchandise.
Lawn mowers are among the most closely watched seasonal products at warehouse retailers.
Costco has carried electric and battery-powered lawn equipment from brands such as Greenworks and other outdoor-equipment manufacturers. Seasonal clearance can occur when a particular mower model is being replaced or when demand begins shifting.
Battery-powered mowers can be particularly interesting during clearance periods because many models are sold as part of equipment systems. A mower may share batteries with a trimmer, blower, or other outdoor tools from the same product family.
Before purchasing a marked-down mower, several details deserve attention:
A lower purchase price does not necessarily mean lower ownership cost. Battery replacement and accessory pricing can influence the long-term value.
String trimmers and leaf blowers are common seasonal lawn-care products and can be affected by inventory changes.
Cordless combination kits can receive particular attention because one battery platform may support several tools. A clearance kit containing a trimmer, blower, battery, and charger can sometimes represent a different value proposition from purchasing individual tools separately.
Important specifications include:
The battery ecosystem is particularly important. A kit with multiple tools but only one battery may have different practical value from a package containing two batteries.
Outdoor cleaning equipment can also move through seasonal inventory cycles.
Electric pressure washers are used for patios, driveways, decks, outdoor furniture, siding, vehicles, and other surfaces. Costco has carried pressure washers from recognizable outdoor-equipment brands, and recent 2026 warehouse coverage has highlighted an AR Blue Clean electric pressure washer among products being seen at Costco.
When comparing a clearance pressure washer, specifications such as PSI and GPM are more meaningful than PSI alone.
Other factors include:
Higher pressure is not automatically better for every surface. Wood, painted surfaces, vehicles, and delicate materials can require lower-pressure techniques.
Planters can be another category affected by seasonal inventory changes.
Large decorative planters, raised garden beds, resin containers, ceramic pots, and other garden containers can take up substantial warehouse space. When seasonal merchandise changes, remaining inventory may be marked down.
Size is especially important with clearance planters.
Large containers may look inexpensive compared with their original price, but transportation and placement can become difficult. Drainage holes, material durability, weight, and exposure to freezing temperatures should also be considered.
Recent Costco coverage has also highlighted seasonal gardening merchandise, including fall bulb collections, showing how quickly the garden department can shift from one season to another.
Raised garden beds have become popular for vegetables, herbs, flowers, and compact gardening areas.
Clearance inventory can include metal raised beds, composite systems, wooden garden beds, and modular planting systems.
Before purchasing a marked-down raised bed, check:
Large raised beds may require considerable soil. The cost of soil, compost, mulch, and irrigation can exceed the original price of the garden bed itself.
Outdoor storage products can remain in seasonal inventory longer because they are useful throughout the year.
Costco has carried prefabricated and DIY shed products, including wooden structures designed for backyard storage. A recent 2026 Costco shed featured a 10-by-7.5-foot footprint, approximately 565 cubic feet of interior space, locking doors, a transom window, and wall vents.
Clearance shoppers should pay attention to more than the advertised price.
Potential additional expenses include:
Some shed packages may not include every material needed for a finished structure.
Outdoor furniture is another major seasonal category.
Costco has historically carried patio dining sets, lounge chairs, sectionals, conversation sets, umbrellas, fire tables, and outdoor accessories. When seasonal floor space changes, remaining patio merchandise may be discounted.
Potential clearance categories include:
For furniture, the condition of cushions and outdoor fabrics deserves attention. A low price can be less attractive if replacement cushions are difficult or expensive to source.
Large patio umbrellas and shade structures are highly seasonal.
Products can include cantilever umbrellas, market umbrellas, umbrella bases, pergolas, and shade canopies.
A discounted umbrella should be evaluated for:
A heavy-duty base may not always be included with the umbrella, so the complete setup cost should be considered.
Garden hoses, hose reels, sprinklers, timers, drip-irrigation kits, and watering accessories can also be affected by seasonal transitions.
These products generally take less warehouse space than large outdoor equipment, but seasonal assortment changes can still lead to markdowns.
Important factors include hose diameter, length, fittings, reel construction, water pressure requirements, and compatibility with existing outdoor plumbing.
For irrigation systems, replacement connectors and fittings can be especially important.
Landscape lighting is another category worth watching.
Costco may carry solar-powered lights, pathway lighting, decorative outdoor lights, string lights, and other exterior lighting products.
Clearance lighting should be checked for:
Solar lighting can lose performance when panels receive insufficient sunlight, particularly in shaded locations.
Fire pits and outdoor heating products can experience significant seasonal changes.
Potential products include propane fire tables, wood-burning fire pits, patio heaters, and outdoor heating accessories.
Safety requirements should be checked carefully before purchasing any clearance product. Installation location, clearance from structures, fuel requirements, ventilation, and local regulations can all matter.
For propane products, the condition of hoses, regulators, burners, ignition components, and fuel connections should be inspected.
Hand tools can include:
These products generally have fewer moving parts than powered equipment, making condition inspection relatively straightforward.
Look for rust, damaged handles, bent components, cracked grips, and missing accessories.
Costco does not necessarily use one universal markdown schedule for every warehouse.
A product can receive a price reduction at one location while remaining at its regular price elsewhere. Inventory levels, regional demand, warehouse capacity, and seasonal timing can all influence pricing.
This is particularly relevant for bulky lawn and garden merchandise because transportation and warehouse space play a larger role than with smaller products.
An item marked down substantially may also have very limited remaining inventory.
Costco shoppers often pay attention to price endings and asterisks when evaluating merchandise, although individual markings should not be treated as a guaranteed nationwide clearance system.
An asterisk on a Costco price tag has commonly been associated with an item that will not be reordered at that warehouse. It does not automatically mean that the item has received a major discount.
Price comparisons should therefore focus on the actual current selling price, product specifications, and comparable models rather than relying solely on a particular price-ending convention.
Lawn and garden inventory can differ between warehouses and Costco's website.
A product may be sold online but not stocked at a local warehouse. Another product may appear at a warehouse but not be listed online.
Large outdoor products can also have different delivery and handling considerations when purchased online.
The Costco website currently separates categories such as Patio, Lawn & Garden and highlights inventory that is subject to seasonal or limited-supply changes.
A clearance price should not be the only consideration.
For powered equipment, check whether the following are included:
For larger products, check delivery requirements and installation responsibilities.
For seasonal furniture, inspect cushions, frames, fasteners, finishes, and packaging.
For garden structures, verify dimensions and foundation requirements before purchase.
Seasonal clearance inventory can move quickly because quantities may already be limited.
Once remaining inventory is sold, Costco may not replenish the exact product. The next shipment could contain a different model, brand, color, configuration, or price.
This is one reason Costco's rotating inventory approach can make seasonal lawn-and-garden merchandise different from traditional year-round retail inventory.
Costco's 2026 lawn and garden inventory is moving through seasonal changes, creating opportunities for markdowns across categories such as lawn mowers, trimmers, blowers, pressure washers, planters, raised garden beds, patio furniture, sheds, outdoor lighting, garden tools, and outdoor heating products.
However, clearance pricing is not necessarily identical across every Costco warehouse. Product quantities, regional demand, seasonal timing, and warehouse inventory can all influence whether a particular item receives a markdown.
