The Best Plants to Grow in a Greenhouse
Ever wonder what’s the best plants to grow in a greenhouse? A greenhouse is not just an excellent environment for your plants; it is also a fun way to showcase your success stories when it comes to plants. That’s why we see greenhouses continuing to rise in popularity worldwide, with gardeners all dreaming of having their own greenhouse.
Of course, one of the benefits of having a greenhouse is that it creates a perfect environment for plants to grow, but we can’t help but wonder whether there are plants that flourish best when they are in a greenhouse.
Do Plants Really Grow Better in a Greenhouse?
Yes, plants grow better and much faster in a greenhouse. There are multiple reasons for this. They are:
- A greenhouse creates a perfect ecosystem for plants.
- The temperature inside a greenhouse is controlled.
- A greenhouse has a high carbon dioxide content.
- There isn’t any exposure to bugs or pests.
- The greenhouse’s atmosphere is humid, which is ideal for plants to grow.
All of these factors make greenhouses the perfect vessels for growing your plants quicker and better.
What plants grow best in a greenhouse?
Squash grows exceptionally well in a greenhouse. It is an excellent plant to grow because it is pretty versatile and can be used in various dishes. In addition, the squash plant is very tough and only requires a clean and bug-free environment to grow well.
Tomatoes grow well in a greenhouse because they love the heat and sunlight. People who start to grow their own tomatoes realize how much better they taste than store-bought tomatoes that are often injected with hormones to boost their size and treated with pesticides. A greenhouse offers the perfect, consistent environment that tomato plants love.
People who enjoy peppers are often shocked by the high costs in supermarkets. They are a great addition to a greenhouse because they grow well without taking up much space. It is great to grow your own peppers because they bring color and flavor to your dishes.
People are often delighted to see how well cucumbers grow in greenhouses. A greenhouse is an ideal place for a cucumber plant because of the high humidity and sunlight. Most people love cucumbers because they are healthy and low in calories. Growing your own cucumbers in your greenhouse is a quick and easy way to add a fantastic ingredient to your salads or pickle them for a tangy treat.
If you love citrus plants, you will be happy to hear that they flourish in greenhouses. By growing oranges, grapefruit, and lemons, your greenhouse will smell wonderful and you will always have your favorite citrus fruit on hand without any harmful pesticides. Enjoy them as they are, in your baking, desserts, or as juice while knowing that they are so much better than store-bought fruit.
People are often surprised to hear that you can grow bamboo in a greenhouse. In fact, bamboo grows incredibly well in a greenhouse because it can be pretty sensitive to weather conditions. Therefore, the consistent environment of a greenhouse is great for bamboo.
When thinking about greenhouses, we often tend to only think about edible plants. However, several plants do very well in a greenhouse that aren’t meant to be eaten. Ferns are one of these plants that flourish inside a greenhouse while being very challenging to grow outside. Ferns don’t like extreme changes in temperature or air that is too dry. Therefore, they grow remarkably well in a controlled temperature and the humid atmosphere of a greenhouse.
Imagine having your own herb garden year-round. Your greenhouse makes it possible for you to have a herb garden every day of the year. This means no more rushing to the store for a bit of mint or rosemary, but instead just popping into your greenhouse for fresh herbs.
Since mushrooms are a fungus that loves humidity, it isn’t surprising that they will do well in a greenhouse. A greenhouse provides mushroom plants with the high temperature and humidity that they need to grow significantly.
People hardly ever think about growing grapes in their greenhouse, but grapes are ideally suited for greenhouse growth. The only downside about growing grapes is that you require a large greenhouse, or they will take over. If you want grapes year-round, consider adding a heater and ventilator for harvesting in the winter.
Strawberries are one of the most popular fruits, with people buying millions of pounds every year. However, they can be very challenging to grow if the conditions aren’t right. This is why a greenhouse is ideal for a strawberry plant because it gives you control over the temperature, meaning you can enjoy your strawberries and cream any time of the year.
Sage is another plant that does exceptionally well in a greenhouse. It is a gorgeous-looking plant that adds beauty to every garden. It also has a great scent, making it a great addition to your greenhouse.
People are often surprised to hear that a cactus plant grows well in a greenhouse, but these plants adore the regulated high temperature of a greenhouse.
What Plants Do Not Grow Well in a Greenhouse?
While greenhouses are an excellent fit for most plants, some don’t do well in a greenhouse. These plants do better outside in the garden or inside your home. Plants that don’t grow well in a greenhouse include:
Hardy spring bulbs
These include tulips, daffodils, and hyacinths. Unfortunately, these plants don’t do well in greenhouses because they need a pretty cold environment, about 40°F or 4°C. This means that a greenhouse is much too warm for the bulbs to grow. In addition, these bulbs need to be in darkness which also isn’t something you find in a greenhouse.
Therefore, these plants grow best outside in your garden as spring plants. However, it is possible to extend their flowering period by moving them to your greenhouse while they are already in bloom, but you need to be careful while moving them.
These include rutabaga, turnips, potatoes, carrots, turmeric, beetroot, celeriac, onions, fennel, sweet potatoes, radishes, ginger, and garlic. These vegetables grow much better in your garden because they need to be in the ground. They need their roots to be unobstructed, and that is why a greenhouse isn’t an ideal environment for them.
These include spinach, broccoli, leek, Brussels sprouts, kohlrabi, cabbage, kale, and collards. These plants benefit more from going in your garden. This is because they get the extra nutrients and water that they need from the soil in your garden.
Kiwi trees grow pretty quickly, but they aren’t ideal as greenhouse plants because they become enormous and they climb, too. Another issue is their large leaves can cast a great deal of shade in your greenhouse. This means that your other plants might struggle to get sufficient amounts of sunlight. If you are adamant about growing a kiwi plant in your greenhouse, it can be done, but it will require a lot of pruning and continuous checking.
Tips for Growing Plants in a Greenhouse
Growing your own plants in your greenhouse can be very rewarding and exciting. Knowing what to focus on to ensure that your plants grow well will help you get the greenhouse you have always dreamed of. Here are a few tips that you should keep in mind when starting with your greenhouse:
Set Your Greenhouse Up for Success
If you want your plants to flourish, you need to have the right tools and supplies. Invest in suitable quality containers, soil that is sterile and nutrient-rich, fertilizer, and water. You can also consider investing in heat sources if you live in an area that has cold winters.
Your lighting in your greenhouse should be sufficient during summer and spring, but you can consider investing in additional lighting for the fall and winter months. By having supplementary lighting, you will get plants that are healthy and strong.
Cool months can be brutal on plants, even in a greenhouse. Therefore, investing in a heating system is a great idea to ensure your plants stay strong during winter. There are three types of heating systems available. First, you can get electric heaters. They are economical and pretty straightforward to install. Second, gas heaters are another option, although they are not as economical as electric heaters.
In addition, you need to set up good ventilation. Finally, the third option is the most eco-friendly because it uses the smallest amount of energy. It involves creating a ventilation system from your home where the unwanted warm air is blown into your greenhouse. In addition, you can add heat-absorbing materials like rocks to absorb the heat and sunlight during the day and then release it during the cooler nights.
Cooling Down Your Greenhouse
In the height of summer, your greenhouse might become too hot, although this will depend on where you live. Your greenhouse has been specifically designed to keep heat in and maintain a humid environment with high temperatures, so your greenhouse may become far hotter than what your plants require.
This means that you might need to monitor the temperature in your greenhouse during hot months. If you find that the temperature is too high, you should consider using evaporative air coolers to maintain the humidity levels.
Keep Your Greenhouse Ventilated
Your greenhouse needs proper ventilation for your plants to grow well. In the warm months, you can keep the wall and roof vents open, resulting in fresh air that is moving through your greenhouse. However, it might be more challenging in the colder months since you don’t want to deal with conditions where your greenhouse is too cold or becomes contaminated with mold. Therefore, it is a good idea to invest in an oscillating fan for the winter months. By running this fan, you will be able to create sufficient ventilation in your greenhouse.
Sufficient watering of your plants
A mistake that many people make who start using greenhouses is watering their plants based on a schedule. Several factors affect the time when plants require watering. These include the temperature, the growth stage of the plants, the humidity, and the kind of plants.
By watering on a schedule instead of when the plants need water, you risk overwatering or not watering enough. Seasons also affect how much watering is required, as the winter months require much less watering than summer months. The best way to know when to water your plants is to take the time to monitor them and water according to their needs.
What Are the Most Common Issues with Greenhouses?
These are the most common issues with greenhouses:
Overheating can be detrimental to your plants. Therefore you must monitor your greenhouse’s temperature if you live in a scorching hot area.
Although greenhouses offer a humid environment that plants love, overly damp conditions can create a risk for mold contamination. If you find that your greenhouse is too moist, try to improve the airflow within your greenhouse.
One of the benefits of having a greenhouse is not using harmful pesticides, but it is still possible for pests to get into your greenhouse. If you find eggs or insects in your greenhouse, remove the plants that have been badly infected to prevent the insects from spreading. Also, be sure to always check new plants before bringing them into your greenhouse.
An Unclean Greenhouse
It is vital to keep your greenhouse clean, even if it is only for your safety. Taking the time to sweep up dirt or fallen leaves creates a pleasant environment that you will enjoy more.
Too Much Sun
Although greenhouses are great for giving plants sunshine, too much of it is not suitable for plants. If you find that your greenhouse is scorching your plants with constant sunlight, add some netting to create a shaded space for some time during the day.
Growing your own plants in your greenhouse is an experience that will enrich your life. In addition, you can share your produce with others and share the benefits of your wonderfully grown plants.
