Discover everything you need to know about greenhouse planting!
Greenhouses provide a great way to grow flowers and vegetables throughout the year. In this guide, we share how greenhouses work, the best things to grow in a greenhouse, and how to make the most of your greenhouse throughout the year.
Greenhouses are used as a controlled environment for growing vegetables and flowers, as they trap sunlight and make heat, helping to create the perfect conditions for plant growth and photosynthesis. A greenhouse also protects plants from frost, which can be highly damaging.
Greenhouses can be used to:
• Grow vegetables during their vulnerable early stages before transferring them outside
• Experiment with growing plants that excel in a warm environment
• Grow vegetables earlier or later in the year than they typically thrive by taking advantage of spring and autumn sun
• Take care of crops during winter that wouldn’t otherwise survive outside of the summer months
Some of the most popular vegetables to grow in a greenhouse include:
• Salad ingredients, like lettuce, cucumbers, radishes, and peppers
• Leafy greens, like spinach and kale
• Different tomato varieties
• Strawberries, figs, and citrus fruits
• Herbs, like basil, parsley, and coriander
There are plenty of flowers that grow well in greenhouses too, such as:
• Pansies
• Dahlias
• Roses
• Sweet peas
• Geraniums
For smaller greenhouses, make the most of the space you have available. For the best results, opt for plants that can be grown in pots, as you can easily arrange these to perfectly fit in your greenhouse.
Different flowers and vegetables need to be planted at different times of the year to ensure they’re given the opportunity to grow and thrive. Start the year with hardy vegetables, such as cabbages, onions, and sprouts which should be planted during late winter and into early spring. When the weather starts to get warmer in mid-spring, you can start sowing tender plants, such as cucumbers, courgettes, and French beans.
Summer is the time to harvest what you’ve grown in your greenhouse and start preparing for your autumn and winter crops.
There are a variety of steps you can take to ensure your greenhouse works efficiently throughout the year. Ensure that all panes are clean using a sufficient greenhouse glass cleaner, as this will allow as much sunlight as possible to enter.
You should also fit insulation to help the interior of your greenhouse trap heat for your plants during cold snaps. Insulation options include bubble wrap, foil, and fleece – all of which do the job without being too expensive.
