Costco stocks all sorts of outdoor products, including plenty of supplies to outfit and maintain your garden. Known for its high-quality finds and flexible return policy, the warehouse is an appealing place to shop for your plant-care needs. So, we've rounded up highly-rated Costco garden products that are worth the buy. These products are from reputable brands, are durable, and are practical for most home gardeners. 

Specifically, these items range from essential planting tools to quaint backyard seating. Each has a minimum of a 4-star average across at least 300 reviews and several have reviews in the thousands. A more detailed breakdown of our methodology is at the end of this article. So, without further ado, here are some of the best Costco garden finds that are worth adding to your cart.

Perfect for container gardening and much easier on your back, the CedarCraft Self-Watering Elevated Spruce Planter is a useful addition to a garden. Measuring 21 inches wide, 47 inches long, and 32 inches tall, it's compact enough for most garden corners, while providing a decent amount of growing space. Casters also make it easy to transport to a patio or deck. Manufactured in Canada, this planter is made of sustainably sourced spruce with rust-proof aluminum legs. The 6-gallon self-watering irrigation system is extra convenient and provides plants with consistent watering.

This product has over 1,400 reviews, earning it a 4.2-star rating overall. One reviewer explains the perks, writing, "It's good looking and well built — a simple but functional box...They aren't heavy and offer water security in case I forget." It's plain useful and ensures plants won't go dry if you're traveling for a bit (or a little forgetful). A few negative reviews note issues with the bottom of the planter falling out if there's too much weight (often occurring after a lot of rainfall). However, with thousands of positive reviews, this does not seem to be a problem for most buyers. Plus, you can be assured that you can get your money back if there are any defects thanks to Costco's lenient return policy.

A personal greenhouse is a gardener's dream. While you can learn how to build a backyard greenhouse, the Palram Canopia Harmony 6' x 8' Greenhouse with Starter Kit takes care of some of the steps for you. Putting this greenhouse together only requires two people and some tools you probably already have around the house (like a cordless drill, rubber mallet, wrench, and screwdriver). The structure has a rust-resistant aluminum frame, durable polycarbonate panels, and a heavy-duty galvanized steel base. An integrated rain gutter, roof vent (with an automated opener), and lockable hinge door add to the design. For the interior, it also comes with a heavy-duty shelf and a plant hanger kit. Once assembled, this greenhouse measures roughly 8 feet long, 6 feet wide, and 7 feet tall.

This is another Costco garden product with hundreds of happy reviews. It has a 4.1-star rating across over 900 reviews. One reviewer wrote: "Got this for my husband ... He said it is well made, had no missing or broken parts, and seemed very sturdy. The vent works as expected and all of our plants are thriving. We had 60 MPH winds the other day and temperatures in the teens and it withstood both very well." A few reviewers had trouble with the installation process and wind resistance, though that's somewhat expected out of an affordable, DIY-install structure.

If you don't have space for a larger greenhouse, the Juwel Biostar 1500 Premium Cold Frame Mini-Greenhouse can still serve a similar function with a much smaller footprint. It has an aluminum frame with polycarbonate panels, as well as an automatic opener which opens and closes the lid when the temperature fluctuates. Just like larger alternatives, this mini greenhouse will protect against frost, cold, wind, and garden pests. It measures 59 inches long, 36 inches deep, and 21 inches tall. Assembly and disassembly are easy with just a screwdriver and pliers, so you have the option to store it away during the off-season.

Many reviewers are happy with this product, giving it 4.4 stars across over 570 ratings. One reviewer happily explained, "I own several of these units now and am buying more for my neighborhood pea patch. [It's] very well made, [and the] auto opener feature is outstanding. Adjustments are simple if necessary. I've owned many cold frames in my day, but this is the unit to purchase."

Compost organic waste and grow new plants in the Vita Keyhole 6' x 6' Composting Garden Bed. This quaint planter is made of food-grade, BPA- and phthalate-free vinyl. It features a central composting basket for you to place your food waste and allow it to compost. The ample surrounding area provides you with planting space to start a garden. This garden bed measures 6-by-6 feet and 22 inches tall, but a smaller 4-by-4 size is also available. It's another easy-to-build and modular product that comes together quickly.

From 838 reviews, this product has a 4.6-star rating, which includes 74% of reviewers awarding it a full 5 stars. According to one reviewer, "We are closing out our third year of growing in our keyhole garden and are still very happy with the purchase. The bed will last a long time and I love composting — I do believe the compost encourages strong growth. We've grown tomatoes, beans, chard, watercress, parsley, dill, [and] arugula." Several reviewers noted some bowing of the sides due to the weight of the soil. However, that doesn't seem to bother some, as it's more of an aesthetic issue. As a solution, some owners installed rebar posts along bowed sections to provide extra reinforcement and ensure better longevity.

Gardeners will appreciate the budget-friendly Vita Mezza Modular Garden Bed. This is a set of two beds, each measuring 48-by-48-inches long and 11 inches tall. The height opens up the possibility of growing deeper root veggies, flowers, and herbs. However, one of the main perks of this product is its easy, tool-free installation. The planks are made from sustainably sourced cedar wood treated with a water-based and environmentally safe stain. They slide right into the aluminum posts, with tongue-and-groove edges to prevent gaps. The design is very flexible, and you can connect multiple beds together to customize your layout. The manufacturer does suggest reinforcing the posts with rebar (not included) if you're connecting units together.

This product has a 4.3-star rating across over 650 reviews. One happy reviewer wrote, "This planting box is super easy to assemble and well made. It's a great concept and so many different configurations can be achieved by this ingenious design." However, some reviewers noted that it doesn't have the best build stability or strength, which is why this product might not appeal to expert green thumbs. A few negative reviews mentioned the thinness of the wood planks. However, sentiments are generally positive since the modular design is versatile, it's pretty affordable, and it's very easy to assemble.

A gardener needs some essential gardening tools for cutting. The Fiskars 15-inch Lopper and Hand Pruner Set is an affordable option from a reputable brand. It includes a 15-inch lopper that can cut through branches up to 1¼ inch thick. A handheld pruner is also included for cutting through thin branches and stems. Both tools have a fully hardened steel blade with a low-friction coating that prevents the blade from getting sticky with sap and debris.

This tool set has 4.5 stars out of over 300 reviews, with 74% ranking it 5 stars. As one reviewer explained, "My wife likes these because they are lightweight and fit her better. These are not for heavy-duty lopping but for smaller items. Good product." 

Some reviewers worried about longevity, as some components are made of plastic. However, the lightweight plastic build is a major advantage for those who have trouble with heavy tools. Plus, Costco sells the combined pair for the same price as other retailers charge for just the lopper (Amazon sells the lopper alone for about $25). So, you might as well get the extra tool for the same cost, especially since many reviewers find it sharp and useful.

Look no further than the Theo Resin Planters by Trendspot if you're shopping at Costco for new plant pots. These outdoor planters come in a two-pack for a budget-friendly price of $43. They're made of recycled resin, so they're lightweight (weighing less than four pounds), and have an eye-catching hand-painted finish that mimics glossy ceramic. Each planter measures 18 inches across and 14.5 inches tall.

Across over 650 reviews, these planters have a high 4.7-star rating, and over 85% of reviewers gave the product five stars. One happy customer described them as "lovely planters that look far more expensive than they are. You wouldn't guess they are resin by looking [at them]... [They are] lightweight, so no difficulty in sliding when necessary." Several reviewers noted they're a high-quality Costco find at this price point.

The Teknor Rapid Flo Compact Garden Hose makes watering tasks a breeze. This product is the hose only (a nozzle isn't included). It measures 100 feet and is ⅝ of an inch in diameter. The hose is lightweight, durable, and kink-resistant. Though simple, these traits make it more long-wearing and nice to use. An abrasion-resistant jacket and ergonomic grips help it surpass a regular old hose. Weighing in at around 50% lighter than heavy-duty vinyl hoses, it's much easier to carry, too.

This product has thousands of reviews, with over 8,000 on the website, resulting in an average 4.3-star rating. Around 70% of reviewers are very happy with their purchase and give this hose 5 stars. One reviewer described its advantages succinctly, saying, "The hose is lightweight, doesn't kink, is easy to roll up, stores easily in the winter, and the couplings work easily in attaching to the faucet and to sprinklers, nozzles, etc. If you're tired of rubber/plastic hoses that kink and get stiff, give this a try." To be expected from a hose with so many reviews, some experience leaks or kinking. Again, though, if you come across one of these issues, the hose can easily be returned to Costco.

Automate watering the garden with the Rachio 3 WiFi Smart Sprinkler Controller. This device brings smart tech to your outdoor space, placing sprinkler control at your fingertips. It connects to in-ground irrigation systems, allowing you to control your sprinklers from a smartphone app to set schedules and adjust settings. Its Weather Intelligence Plus technology monitors conditions and adjusts watering according to rain, wind, snow, and freezing temperatures. This feature means the system can help you save water. So, even if this system has a higher upfront cost, it can be worth the investment, especially if you're looking for convenience.

Plenty of reviewers agree with that since this product earned a 4.7-star rating from over 4,000 reviews. Impressively, over 80% of reviewers give this product a full 5 stars. One says, "This Rachio system is simply fantastic. Since it's WiFi connected it knows where I am, what kind of grass I probably have, what kind of soil I probably have, and it even knows to skip the morning watering because of the rain forecast for this evening. I never have to [use] the controller for anything, I can do it all from my cell phone." Some negative reviewers were unaware that this unit can only be installed indoors as-is. To place it outside, you'll need a Rachio Smart Sprinkler Weatherproof Outdoor Enclosure, which comes at an additional cost.

Gardeners need a place to put their tools, and if your garage is too full, an outdoor shed is the next best thing. The Suncast 6' x 5' Modern Shed is a highly-rated pick from Costco with plenty of appealing features, and it looks pretty stylish, too. It has a steel frame with resin walls that stand up to all weather conditions. Measuring around 6-by-5 feet, and 5 feet tall, the structure offers 200 cubic feet of protected storage space. This is enough to fit a lawn mower or wheelbarrow and an array of smaller tools (some of which you can hang on the three included tool hooks). Vents and transom windows make it more comfortable when you need to step inside the shed. The doors are also lockable using a padlock (not included) to protect your garden tools and keep kids and pets out. 

This product has over 2,400 reviews and a 4.5-star overall rating, with 73% of reviewers awarding it 5 stars. One pleased shopper wrote, "The Suncast shed was time-consuming to put together, but it looks great, is spacious, and feels like high quality ... We also had some rain and found out that the shed is very waterproof and there was not one drop of water inside." Negative reviewers experienced missing parts and subpar service from Suncast. However, with overwhelmingly positive reviews, most reviewers are happy with their shed.

Cozy seating can make a garden even more enjoyable. The Hargrove Cast Aluminum Bench is compact and has a traditional park bench look that's appealing for quaint gardens. An antique bronze finish leans even more to its timeless aesthetic. One modern feature is the adjustable feet, which are especially useful to prevent wobbling on uneven garden flooring. Plus, it's lightweight, so you can move it around to sit in different parts of the yard.

This product has a 4.6-star rating from over 600 reviews, with over 76% giving it 5 stars. Pleased reviewers appreciate the quality for its price, with one calling it "a well made, lightweight bench that is good value for the money... Directions were straightforward and the bench was very easy to put together. Overall, for something that is going to sit out in the weather, stable and light weight and not terribly expensive, I am very satisfied." Pair this bench with one of the best patio heaters you can find at Costco to stay cozy on chilly nights.

If you need to thicken your grass or repair patches on your lawn, Costco has a promising option. Scotts EZ Seed Patch & Repair Sun and Shade is designed to fill in sparse parts of a lawn. This bag holds 25 pounds of seed, which is enough to cover up to 556 square feet, so one bag can last several seasons for small lawns and gardens. It's useful for filling in bare spots in your grass and will even seed in tough conditions, including full sun, dense shade, on slopes, and in high-traffic zones.

Out of over 300 reviews, this product has 4 stars overall, with over 60% rating it a full 5 stars. Many happy reviewers say it works well when used correctly, with one explaining, "The stuff works great if you follow the directions and lay it on thick. It is for patch repair, not for seeding an entire lawn. The mixture prevents the seeds from washing away and if they're kept wet and laid on thick they'll sprout in 2 weeks." This product promises a lot, and grass can be finicky, so some negative reviews say that it didn't work for them. However, others reported that attentive watering was key to success with this seed.

The products on this list are some of Costco's highest-rated and most popular garden items. They're well-liked for good reason, with hundreds of positive reviews praising their usefulness and quality. The above picks had at least a 4-star rating from over 300 reviews. Beyond ratings, we also considered the product's features and what it offers for its price. We included a variety of items that provide some level of convenience or necessary utility to most home gardeners.
