Did You Know?
1. If you’re looking to keep pests away from your greenhouse plants, avoid using mothballs. Although effective in repelling insects, mothballs can give off harmful fumes when exposed to heat and can lead to health issues for humans and plants alike.
2. Did you know that bananas should not be stored inside a greenhouse? As bananas release ethylene gas as they ripen, it can accelerate the ripening process of nearby fruits and vegetables, causing premature spoilage.
3. While it may seem like a good idea to bring your pet inside the greenhouse, keep in mind that certain plants can be toxic to animals. Avoid placing poisonous plants, such as lilies, daffodils, or oleander, inside the greenhouse to ensure the safety of your furry friends.
4. If you’re considering using oils or oil-based products as gardening remedies inside the greenhouse, be careful with application near plants. Oils can block the pores of leaves, hindering photosynthesis and leading to damage or death of the plant.
5. Although it may be tempting to burn wood or charcoal for heat inside a greenhouse during colder months, this practice should be avoided. The combustion process releases carbon monoxide, a colorless and odorless gas that can be deadly when inhaled in high concentrations. Opt for safer heating alternatives, such as electric heaters or geothermal systems, to ensure safety in your greenhouse.
Hardy Spring Bulbs
When it comes to greenhouses, it’s important to be aware of which plants are suitable for the environment. Hardy spring bulbs, such as hyacinths, narcissus, and tulips, are not ideal choices for a greenhouse. These plants require a period of dormancy during the winter months, which allows them to rest and rejuvenate before blooming in the spring. In a greenhouse, this natural cycle can be disrupted, resulting in weak and stunted growth. Additionally, the controlled environment of the greenhouse might not provide the necessary chilling requirements for these bulbs to thrive.
Therefore, it’s best to plant hardy spring bulbs directly in your garden where they can experience the full range of seasonal changes.
- Hardy spring bulbs, such as hyacinths, narcissus, and tulips, should be planted directly in the garden
- Greenhouses are not suitable for these bulbs as they require a period of dormancy
- The controlled environment of the greenhouse may not provide the necessary chilling requirements for these bulbs to thrive.

Root Vegetables
When it comes to growing root vegetables like turnips, carrots, and potatoes in a greenhouse, it’s best to think twice. These plants require ample space to develop their underground tubers, which can be limited in the confines of a greenhouse. Moreover, the controlled environment of the greenhouse can lead to excessive moisture and humidity, making the soil too wet for the roots to thrive.
- Root vegetables are best suited to open garden beds where they can spread out and develop to their full potential.
Hardy Vegetables
While greenhouses offer a great opportunity to extend the growing season, certain vegetables are better off being grown outdoors. Plants like broccoli and spinach, commonly referred to as hardy vegetables, thrive in cool temperatures and even tolerate light frost.
Greenhouses tend to trap heat and humidity, creating an environment that is too warm for these plants. Additionally, the lack of natural air circulation in a greenhouse can lead to increased susceptibility to diseases and pests.
To ensure healthy and robust growth, it is recommended to grow hardy vegetables like broccoli and spinach in outdoor garden beds.
- Greenhouses are beneficial for extending the growing season.
- Broccoli and spinach are considered hardy vegetables.
- These vegetables thrive in cool temperatures and tolerate light frost.
- Greenhouses trap heat and humidity, which is not ideal for hardy vegetables.
- Lack of air circulation in greenhouses can increase the risk of diseases and pests.
Citrus Trees
Citrus trees, such as lemon and orange trees, may seem like an appealing addition to a greenhouse due to their delicious fruits and exotic appearance. However, these trees require a large amount of space to grow properly, which can be challenging to provide within the limited confines of a greenhouse. Furthermore, citrus trees are highly sensitive to temperature fluctuations and require a specific amount of cold exposure during the winter months to produce flowers and fruits. The controlled environment of a greenhouse may not meet these requirements, resulting in poor growth and diminished fruit production.
It is recommended to plant citrus trees in a suitable outdoor location where they can receive the necessary amount of sunlight, airflow, and cold exposure.
Kiwi Plants
With their tempting fruits and lush foliage, kiwi plants might seem like a perfect fit for a greenhouse. However, these vigorous climbers need substantial vertical space to thrive and produce an abundant harvest. In a greenhouse, where space is typically limited, the growth of kiwi plants can be severely restricted, leading to compromised health and reduced fruit production.
Additionally, kiwi plants require cross-pollination with a male plant for fruit production, which can be difficult to achieve in an enclosed greenhouse environment. Therefore, it’s best to reserve greenhouse space for plants that are better suited to these limited conditions and grow kiwi plants in spacious outdoor areas.
“When it comes to greenhouse gardening, it’s important to choose the right plants for optimal results.”
