Collection: High Quality Portable Greenhouses

Not every gardener has the space, the budget, or the landlord for a permanent greenhouse, and that is exactly why we love portable greenhouses. These clever little structures go up in an afternoon, often without a single tool, and give your seedlings, herbs, and tender plants a sheltered spot to thrive. When the season changes or you move, you simply pack it up and take it with you.

Portable greenhouses are the easiest, most affordable way to start protected growing. There is no foundation to pour, no permits to chase in most areas, and no long-term commitment. Set one on a patio, deck, balcony, or corner of the lawn, and you can start seeds weeks earlier, protect plants from a surprise frost, and keep pests off your young crops.

At Mulberry Greenhouses, a small, woman-owned shop in Georgia, we have hand-picked portable options from trusted names like Riverstone and Exaco, from walk-in units and rolling shelves to cold frames and miniature raised-bed greenhouses. Here is how to choose the right one and get the most from it.

Why Choose a Portable Greenhouse?

• Fast, easy setup: Most portable greenhouses assemble in an hour or two, many with no tools required.
• No foundation needed: Place it on a patio, deck, lawn, or gravel, and anchor it securely. No concrete, no digging.
• Flexible and movable: Chase the sun, shift to shade in summer, move indoors in a cold snap, or take it to your next home.
• Low cost of entry: A fraction of the price of a permanent greenhouse, which makes it perfect for trying protected growing for the first time.
• Renter and HOA friendly: Because nothing is permanent, portable structures are often easier to fit within lease terms and neighborhood rules. Always check yours first.
• Season extension: Start earlier in spring, grow later into fall, and protect plants from light frost, wind, heavy rain, and critters.

Types of Portable Greenhouses in Our Collection

Walk-in portable greenhouses. The Riverstone Genesis Portable Walk-in Greenhouse gives you a true walk-in growing space with a powder-coated steel frame, two levels of wire shelving on both sides, and a heavy-duty reinforced PE cover. It comes in a small size (about 61 in long x 28 in wide x 79 in tall) and a large size (about 61 in x 56 in x 79 in). A dual-zipper door rolls up for ventilation and zips closed when temperatures drop, and assembly requires no tools.

Rolling greenhouse shelves. The Genesis Portable Greenhouse with Wheels comes in 3-tier and 4-tier versions on caster wheels, so you can roll it from shade to sun, or right into the garage or family room on a cold night. Choose a clear PVC cover for maximum light or an opaque, heavy-duty PE cover that softens light and helps keep young plants from drying out.

Cold frames. Low, compact, and incredibly useful, cold frames are the original portable greenhouse. Our Exaco Juwel lineup includes the BioStar 1000 (about 3 ft x 2 ft) and BioStar 1500 (about 5 ft x 3 ft), the Year-Round 4 ft x 2 ft Cold Frame, and the Easy-Fix Double Cold Frame. They are perfect for hardening off seedlings, growing salad greens into the cold months, and protecting low crops. See all of our cold frames.

Raised beds with built-in protection. Want a garden bed and greenhouse in one? The Exaco Juwel Kombi works as a raised bed and a cold frame, and the Riverstone Eden Garden Bed acts like a miniature greenhouse over your soil. Browse more options in our garden beds collection.

Who Are Portable Greenhouses Best For?

• Renters who want to grow without making permanent changes to a property.
• Small-space gardeners working with patios, balconies, townhome yards, or narrow side yards.
• Seasonal growers who want a jump on spring planting or a little extra protection in fall, then store the greenhouse away.
• First-time greenhouse gardeners who want to learn the ropes before investing in a larger structure.
• Experienced gardeners who want an extra hardening-off station or overflow space next to their main greenhouse.

Portable vs. Permanent Greenhouses: Which Is Right for You?

We sell both, so we will be honest. A portable greenhouse is fantastic for flexibility and cost, but it is not a substitute for a permanent greenhouse in every situation.

Portable greenhouses win on: price, speed of setup, mobility, and freedom from foundations and long-term commitments. They are ideal for seedlings, herbs, greens, and protecting plants through short cold spells.

Permanent greenhouses win on: space, durability, insulation, and wind resistance. Rigid panels and a proper base hold heat better, stand up to storms, and give you room for full-size crops, benches, heaters, and fans. If you want to grow through a real winter or keep tomatoes going all summer long, a permanent structure will serve you better.

Many customers start with a portable unit, fall in love with greenhouse growing, and then upgrade. When you are ready, explore our small greenhouses, insulated Solexx greenhouses, durable polycarbonate greenhouses, or our full range of greenhouse kits. Your portable greenhouse can then live on as a seed-starting or hardening-off station.

Setup Tips: Placement, Anchoring, and Airflow

Choose a bright, sheltered spot. Aim for at least six hours of sun, ideally with some protection from strong prevailing winds, such as the side of a house, a fence, or a hedge.

Anchor it, every time. This is the most important tip we can give. Lightweight portable greenhouses can catch wind like a sail. Use stakes, guy lines, sandbags, or weights, and secure the frame to a fence, deck, or wall whenever you can. In windy areas, consider a tie-down kit, and on stormy days, take the cover off or move the unit to a sheltered place.

Keep it level. A level surface keeps the frame square, zippers working smoothly, and shelves stable.

Ventilate on sunny days. Small greenhouses heat up fast. Roll up the door on warm mornings and close it again in the late afternoon to trap warmth for the night.

Water smart. Small containers dry out quickly in a warm greenhouse. Check daily in warm weather or set up an easy drip kit from our watering systems.

A Year with Your Portable Greenhouse

Late winter: Start tomatoes, peppers, and flowers from seed. On very cold nights, roll a wheeled unit indoors or add a frost blanket. LED grow lights can help indoor seedlings stay sturdy.

Spring: Harden off transplants in a cold frame or walk-in unit by opening it a little more each day before moving plants to the garden.

Summer: Use an opaque cover or partial shade, keep the door open, and grow herbs or propagate cuttings. In the hottest months, many gardeners simply pack the cover away.

Fall and winter: Sow lettuces, spinach, and other cool-season greens in a cold frame, and shelter potted herbs and tender perennials from early frosts.

Caring for Your Portable Greenhouse

A little care keeps a portable greenhouse going for many seasons. Wash the cover with mild soap and water at the start and end of each season to keep light levels high. Store covers clean and completely dry to prevent mildew, and keep them out of direct sun when not in use, since UV slowly weakens plastics over time. Check zippers, stakes, and ties regularly, and replace a worn cover rather than the whole greenhouse when the time comes.

How to Choose the Right Portable Greenhouse

With several styles to pick from, a few simple questions will point you to the right one:

• Do you want to walk inside? If you like stepping in to water, prune, and pot up, choose a walk-in model like the Genesis Portable Walk-in Greenhouse. The large size gives you shelving on both sides with an aisle in the middle.
• Do you need to move it often? A wheeled unit like the Genesis Portable Greenhouse with Wheels is the easiest to roll between sun and shade, or into the garage when frost threatens.
• Are you mostly growing low crops? Lettuces, spinach, radishes, herbs, and hardening-off trays are happiest in a cold frame, which hugs the ground and holds warmth close to the soil.
• Do you want a bed and a greenhouse in one? Choose a raised bed with a built-in cover, like the Juwel Kombi or Riverstone Eden Garden Bed.
• How much space do you have? Measure your patio, deck, or yard spot, and leave room around the greenhouse to open doors, lids, and zippers comfortably.

What Can You Grow in a Portable Greenhouse?

Portable greenhouses are at their best with plants that are small, young, or only need a little extra protection. Favorites include tomato, pepper, and eggplant seedlings; flower starts like zinnias, marigolds, and petunias; culinary herbs such as basil, parsley, cilantro, and chives; salad greens, spinach, arugula, and Asian greens; strawberries in containers; and cuttings of perennials, succulents, and houseplants. A cold frame can keep hardy greens like kale and mache producing deep into the cooler months, even in regions with frosty nights.

Large, long-season crops, like indeterminate tomatoes that climb six feet tall or fruit trees, are better suited to a permanent greenhouse, where you have the headroom and stable conditions they need.
