If you've been dreaming about or planning a greenhouse for your garden, there are some essential things you need to consider before investing. 

With glasshouses and greenhouses providing a beautiful, undercover alfresco space, and the capacity to grow a huge variety of vegetables and fruit, it is not surprising many of us have been dreaming of different greenhouse ideas for our gardens during lockdown.

However, the experts at Hartley Botanic have provided some advice below on what to consider when planning a greenhouse for your garden. 

This includes greenhouse location, size and design, along with important considerations when it comes to installation and maintenance.

What to consider when planning a greenhouse

1. Lockdown dreaming is useful

Spend time envisaging how you intend to use your greenhouse before deciding on a size and style. Will you use it purely as a growing tool or as a dual-purpose growing and al fresco space? How will the design of your greenhouse fit into the garden ideas  and design you already have?

2. It's all about location

It is very important to get the location of your greenhouse right. It needs plenty of sun throughout the year, in a location which does not become too exposed in cold weather. It also needs to be cited near a water supply.

3. Consider the soil

If you want to include growing beds within your greenhouse you need to make sure the soil it is positioned on is fertile. 

Take a look at the best vegetables to grow in a greenhouse to help decide what kind of soil, and how much space, you will need to grow food in your greenhouse if that's what you desire.

4. Will you need planning permission? 

Generally, this is not required when installing a Greenhouse for domestic-use, but do your homework if you live in a Grade Ior Grade II listed property, or are lucky enough to live in an area of outstanding natural beauty.

5. Prioritise ventilation

One of the most common reasons for plant failure in greenhouses is due to insufficient ventilation. Ventilation is prioritised in Hartley Botanic structures – make sure it is a priority for you too when choosing a structure.

‘We have experienced a renewed interest in our glasshouses and greenhouses during lockdown,' says Tom Barry, Managing Director of Hartley Botanic.

'Many of our existing customers are making use of their beautiful Hartley Botanic structures as a way to while away the hours and the pandemic has thrown back into focus the idea of becoming more self-sufficient.'
