Greenhouses are a gardener’s best friend. They extend the growing season, protect plants from pests and the elements, and can even increase yields.
But not all greenhouses are created equal.
So, what’s the best greenhouse for growing tomatoes? Well, that depends on your needs, budget and the amount of space that you have available.
In this blog post, we’ll explore the different types of greenhouses and help you decide which is best for you.
Greenhouses that use glass are the best choice for tomato growing due to strength and heat retention properties but you call also use more cost effective plastic houses with good results too. The best greenhouse will be one that is well made, has plenty of space and suits your budget.
Why should you use a greenhouse for growing tomatoes?
We all know that growing tomatoes is possible in almost any garden.
But you will achieve much better results if you use a greenhouse to grow them in, especially if it’s your first time.
Here are some of the reasons why using a greenhouse for growing tomatoes will give you better harvests:
A greenhouse offers protection from insects and birds which can cause serious damage to plants.
It offers protection from the elements which can reduce blooms and fruit set.
Your greenhouse will create dry warm conditions which are perfect for growing tomatoes.
Good temperature control means that you can avoid tomato problems.
Unless you are lucky enough to live in a warm area with good levels of sunshine you will need a greenhouse to extend the growing season to help your tomatoes reach their full potential.
Which greenhouse design should you choose?
When choosing a greenhouse for growing tomatoes we recommend that you opt for an unheated greenhouse rather than a heated one.
The reason is that heating your greenhouse will require more energy and maintenance costs.
As far as the choice of plastic or glass goes, it all depends on how much money you want to spend and the amount of space you have available.
Plastic greenhouses offer a more cost effective option than glass greenhouses but they don’t insulate as well and require more sun for optimal growing conditions.
A small plastic greenhouse is an economical way to start with, especially if you are a beginner at growing tomatoes.
If you decide that you want to upgrade later on, you can simply replace the plastic greenhouse with a glass one.
It’s important to remember though that the smaller your greenhouse the less space you will have available for growing tomatoes so consider carefully before buying something too small.
Another thing to bear in mind is that plant support structures often come as part of a package with the greenhouse itself.
If possible, it’s a good idea to purchase greenhouses that have built-in support structures because this will save you money and time.
Which tomatoes should you grow in your greenhouse?
Before you start ordering tomato plants for your greenhouse, find out how much sun they require.
Some varieties need more light than others so you will have to choose accordingly.
If possible, it’s a very good idea to start with disease resistant tomatoes because the threat of diseases is much lower when growing in a greenhouse.
If you want tasty, fresh and healthy homegrown tomatoes then we highly recommend that you buy an heirloom variety which has been bred for taste rather than appearance.
When choosing tomatoes for your greenhouse, go for small fruited varieties which won’t grow too big and will often produce large amount of sweet tasting tomatoes.
Can you grow tomatoes all year round in a greenhouse?
Yes, you can grow tomatoes all year round in a greenhouse but only if the greenhouse is heated and you may also have to provide some form of artificial light to compensate for lower levels of natural daylight.
Heaters can be electricity powered or fuelled by paraffin and you can obtain reliable and cost effective growing lights that can be mains or battery powered too.
What to look for when buying a greenhouse for tomato growing
The first thing to consider is how much effort and money you want to put into growing tomatoes in a greenhouse.
If you just want to experiment with your gardening skills without spending too much then it makes sense to go for an unheated plastic greenhouse.
As your gardening skills improve then you might want to grow different varieties of tomatoes and maybe even other plants that grow well under protection such as peppers, grapes and more.
When selecting your greenhouse there are a few considerations:
Budget – greenhouses range from low cost plastic covered houses that are simple to erect and that can be easily moved right through to larger, glass covered structures that require foundations.
Your budget will be a prime consideration.
Size – The size of the greenhouse will need to be suitable for the amount of outdoor space that you have available while providing enough room for your growing needs.
It is a good idea to get the largest greenhouse that you can accommodate as you’ll soon discover that you need more growing space.
Materials – Greenhouses come in a variety of materials from aluminium and wooden structures with glass through to push fit steel framed houses with plastic covers.
The aluminium and wood houses are the most resilient and will stand up to the worst that the weather can throw at them while the plastic houses are easy to assemble but can be prone to wind damage if not secured properly.
Ease of construction – how difficult is the greenhouse to install?
Wooden and aluminium structures will typically need some form of foundation to enable them to be secured to the ground so you will need to think about this.
Lifespan – A permanent greenhouse made of wooden or aluminium frames will last for decades if installed correctly whereas a plastic covered house may only survive one season if it is exposed to high winds.
Heat retention – plastic covered greenhouses are colder than glass covered structures making them less suitable for use in colder weather or colder climates.
Glass has thermal properties which enable it to allow sunlight in while slowing the escape of heat.
