Secrets of Commercial Greenhouses

No matter if you are considering opening a commercial greenhouse, selling a few plants from your front yard, or simply want to grow better plants, knowing a few inside secrets of commercial greenhouses is an appealing idea. These tips from the commercial greenhouse experts can help your plants and your business flourish.

The best selling plants are annuals, herbs, and foliage plants. 6" pots sell best, and carefully pruning off discolored leaves and over-ripe blooms encourages customers to purchase more plants.

Impatiens are a very popular bedding plant. Marigolds and geraniums are good sellers as well. Ferns are terrific sellers and nearly every commercial greenhouse includes these green favorites. Include a few hydroponic vegetables, such as tomatoes, peppers and cucumbers, in your selection of plants.


If you are selling your plants to consumers, include a display of basic gardening supplies and seeds to help boost sales. A selection of gardening books and magazines is also a great way to increase your profits.

Keep a nursery log. Include important growing information for each type of plant for easy cross reference on peak times and suggested plant care.

Place fragrant plants near the entryway of the greenhouse to entice customers into the structure. Mix colorful plants in with greens to provide a visually appealing selection.

Fresh, moving air is essential to healthy plant growth, especially in winter months. Use a thermostat controlled heater to maintain temperatures of between 70-75° while ventilation flaps are open.

Take care of any standing water inside your greenhouse to prevent excessive humidity. Some commercial greenhouses will dig a ditch along the sides of the greenhouse wall to aid proper drainage and avoid standing puddles of water.

Invest in cooling pads to keep the humidity down and the soil moist. Keep in mind that using a cooling fan will decrease the overall temperature of the greenhouse by 10° for each fan used.


Growing terrific plants like commercial greenhouses is easy with a few insider tips like these. Commercial greenhouses pay top dollar for marketing and gardening experts, but you can take advantage of their secrets by observing the habits of successful commercial greenhouses.
