It’s exciting when you begin to explore the opportunities that are available for growing plants or vegetables in a greenhouse.
Whether you have toyed with the idea or you’re ready to jump in and start, we’ve put together a basic guide for growing vegetables in a greenhouse for beginners.
Buying a greenhouse
There are thousands of
greenhouses to choose from and the choice is entirely yours, however, if you
are new to gardening or greenhouses, perhaps consider choosing a smaller
You could start with an Ultimate Spacesaver Greenhouse, a small, manageable greenhouse ideal for beginners
or people who don’t have much space in their garden or a bigger one such as the 4x6ft
Ultimate Greenhouse to get you started. It totally depends on what you want to achieve and how much you want to invest in your project.
One thing you don’t
want to do is overwhelm yourself and
lose interest in your project because it seems too hard.
Where to build your greenhouse
Once you have purchased your greenhouse, the next thing you need to think about is where you are going to build it. Ideally, you need a spot which has maximum sun exposure but sheltered from cold winds.Another thing to take into consideration is having easy access to water and electricity.
What to grow your plants & vegetables in
For beginners, if you have a greenhouse with a soil floor, its best to start growing in ground soil, it will be easier to manage watering and fertilisation, however growing in containers, grow bags or bulb crates have their advantages, no weeding and reduced cases of soil borne diseases.
Again, the choice is yours.
What will you be growing?
Knowing what you are going to grow is one of the first steps to getting started in your greenhouse. Before you choose the plants and crops you want to grow, research what environments, temperatures and humidity your plants and crops will need to thrive.
Try not to overstock the greenhouse at the beginning of your journey, overcrowding plants can cause the plants & vegetables stress as the lack of space will make them unable to produce properly.
We have listed a few easy to grow vegetables to help get you started;
- Salad leaves
- Spring onions and radishes
- Broad beans
- Runner beans
- Onions and garlic
- The list goes on.
Understand your growing temperatures
Get a thermometer. It will be the most invaluable item you own whilst growing in your greenhouse.
You will need to research what temperature to keep your greenhouse for the type of plants/vegetables you are growing as some will need more heat than others so be sure to check the temperature and humidity regularly in your greenhouse.
It’s imperative to keep the greenhouse at the right temperature so your plants and vegetables grow in full.
A little research into heaters, vents and fans will go a long way when getting the temperature right for your greenhouse. It’s best to get a good understanding of what’s involved when controlling the temperature and humidity throughout the seasons.
Light and space in the greenhouse
Your greenhouse should get enough natural light for your plants and crops to grow during late spring and summer but if you want to continue to grow in Autumn and Winter you may need to consider purchasing extra lighting.
There are hundreds of grow lights available, LED grow lights tend to be the most popular however if you are in a smaller greenhouse or growing a smaller crop, a normal fluorescent strip can be hung 3-7 inches above the plants.
Make sure your plants and crops have enough space to breathe. Plants which are touching each other tend not to grow as well and it encourages the spread of disease.
Caring for your plants & vegetables
Once you have the temperature and humidity under control in your greenhouse, the most important part to keep your plants and crops happy and healthy is water! Investing in a water-butt to collect rainwater is a great source of water for your plants.
Don’t go water mad though, some crops will need more than others and you will need to keep an eye out on plant size and temperature. Try not to cause too much splashing when watering your crops, this is to avoid the spread of diseases.
Keep an eye out for bugs, slugs and other nasty little critters, many people choose to slug watch before they leave the greenhouse for the night. Keeping your greenhouse clean and tidy also helps with pest control.
There you have it, from selecting your greenhouse to caring for your crops, we hope you enjoyed reading our article on growing vegetables in a greenhouse for beginners.
