Where are you located and what are your hours?

We're located at 1060 West Tennessee Ave. in McCaysville, GA. Our doors are open Monday through Saturday from 9:00 AM to 5:00 PM, and Sunday from 12:00 PM to 5:00 PM during the peak spring and fall season.

When is the best time to visit for the best selection?

Our greenhouses work a lot like a bakery — the earlier you come, the better the selection. We begin growing for spring in December, and by late March to early April the houses are packed full. If you’re looking for the widest selection of plants, early April is the sweet spot.

Fall has its own busy season, too. From September through October, we’re growing and stocking mums, pansies, shrubs, and trees. Stopping by during that window gives you the best look at what we’re offering before things start selling through.

When can I plant my garden?

Around here, vegetable gardens don’t all get planted at once. Many cool-weather crops can go in early spring and handle chilly nights just fine. As the season warms up, you can keep adding crops a little at a time.

We do recommend holding off on warm-weather vegetables like tomatoes and peppers until after our last frost date, which is typically around May 10 in the McCaysville and Copper Basin area. Planting too early often means extra stress — or extra covering.

Vegetable planting doesn’t end in spring, either. Many crops can be planted through late June and into early July, especially when you keep our usual first frost in mind, which often falls around the third week of October.

Are you open during the winter and summer months?

Quinn’s Greenhouse is open seasonally, following the natural rhythm of the garden. We take a short break during the hottest part of summer and the coldest part of winter, when growing slows and plants need rest.

That said, we’re never far away. We’re open by appointment year-round and are always happy to meet folks when they need us. Living just down the road makes it easy for us to work around your schedule whenever possible.

Questions We’re Asked at the Greenhouse

Whether you're a seasoned gardener or a first-time grower, we're here to help you cultivate your green thumb.

What zone do I need to plant for?

On paper, we’re Zone 7 — but mountain gardeners know it’s never that simple. With our hills, valleys, and changing elevations, we often garden like we’re in Zone 6. That’s why we select plants that can handle cold snaps, late frosts, and the ups and downs that come with mountain weather.

How do I amend this red clay?

Red clay is part of life in our area — and with a little work, it can grow great plants. The key is improving drainage and adding organic matter so roots can breathe and water can move through the soil instead of sitting on top.

For most gardens, we recommend working in organic materials like mushroom compost and Black Kow. These help loosen heavy clay, improve soil structure, and add nutrients over time. Mixing them into the top several inches of soil makes a big difference, especially before planting.

For perennial beds, we also suggest adding Soil Perfector. Soil Perfector helps open up clay soil permanently, improving drainage and root development year after year. Unlike organic matter, it doesn’t break down, making it a great long-term investment for perennial gardens.

Clay soil can be stubborn, but with the right amendments and a little patience, it can become productive, workable soil that supports healthy plants for the long haul.

What is the difference between heirloom, hybrid and GMO?

Not all seeds are created the same, and the labels can be confusing. Here’s a simple breakdown of what those terms really mean.

Heirloom seeds are open-pollinated varieties that have been passed down for generations. They’re valued for flavor, history, and the ability to save seed from year to year. If you’re specifically looking for heirloom varieties, we recommend our Seed Exchange Seed selection, which focuses on time-tested, traditional plants.

Hybrid seeds are created by naturally crossing two parent plants to bring out specific strengths like disease resistance, uniform growth, or higher yields. Hybrids are not genetically modified — they’re simply the result of careful plant breeding, something farmers and gardeners have done for centuries.

GMO seeds are genetically modified in a laboratory by altering a plant’s DNA in ways that do not occur naturally. We do not sell GMO seed at Quinn’s Greenhouse. You won’t find them here.

Whether you prefer heirloom varieties for their history or hybrids for their performance, we’re happy to help you choose seeds that fit your garden, your goals, and our local growing conditions.

Is Quinn's Greenhouse dog-friendly?

We love four-legged friends! Well-behaved dogs on leashes are more than welcome to join you as you wander through our garden paths. Just look out for the resident greenhouse cats!
