Classic Greenhouse Gardening Mistakes

Growing plants in a greenhouse require a bit of knowledge and skill. It may take some effort ahead of time to avoid making one of these common greenhouse gardening errors. But no need to fret! We have curated a list of things you need to watch out for.


Your plants may perish if your greenhouse has poor or no ventilation. You can release the trapped, heated air through roof vents. Sometimes, your plants may need a small fan to sustain ample air circulation.

Convection currents generated by natural heat alone would be enough to sustain healthy heat circulation during the summer. Keeping the wall vents and the roof vents open throughout the summer enables cold air to enter via the walls. In contrast, hot air escapes through the roof, providing a constant stream of fresh air.

Maintaining air circulation and controlling mold formation might be more challenging during the winter. Working to ensure the soil is not overwatered can do a lot. Many greenhouse gardeners have an adjustable fan going throughout the winter.


One of the most common errors made by new gardeners is failing to monitor their greenhouse's temperature regularly. To avoid wilting your plants, opt to use a standard or digital thermometer that provides actual humidity reading, which would be necessary to prevent heat loss.

Heating a greenhouse during the cooler months may be an educational experience in and of itself. Electric heaters are recommended for beginners. They are simple to install, less expensive, and offer a fuller range of uses. A simple 120-volt heater will generally suffice to heat a small greenhouse. On the other hand, Larger greenhouses will require a 240+ volt heater regulated by a dependable, waterproof thermostat.

During summer, it can be challenging to maintain a stable temperature in a greenhouse. Cooling a greenhouse that has been too hot is significantly more demanding than heating a greenhouse that has become too cold. During the hotter months, it is essential to track the temperature within the greenhouse frequently. If your greenhouse constantly overheats, install evaporative air coolers to keep the humidity.


Watering plants on a schedule is one of the most common blunders that beginners commit. A variety of factors influence when plants need to be watered. The temperature, humidity, and the stage of growth of the plants themselves all substantially impact how much water is required.

You may only need to water a seed bench once every ten days in the dead of winter. During the summer, the frequency will rise. The easiest approach to determine when to water the plants is to detect moisture in the soil, either using specialized moisture meters or simply by sight and feel.
