Peas and beans growing in a Polytunnel
March often feels as if it’s still winter, especially with it’s famous ‘March winds’ which can quickly make you wish you were back inside where it’s warm. But in a First Tunnels Polytunnel, the wind isn’t a problem and you can focus instead on what’s happening to all your overwintering plants – which are suddenly growing, and many of which are either actively bolting or thinking about it.
If you started off any tomato plants under lights in January they should begin flowering about now. As it’s roughly 60 days from seed to flower and another 60 days from flower to fruit, early tomato flowers means a crop that you can be enjoying long before any blight appears.

Polytunnel with Sliding Door
March offers us a wide variety of weather. On colder days it’s easy to forget that in the warmer climate of the polytunnel, plants are coming out of dormancy and therefore need more water than at any time over the past several months. Don’t forget ventilation either – First Tunnels sliding doors are a fantastic addition to any Polytunnel. The ground bolt locking system allows you to secure the doors in a position of your choice giving greater control and flexibility over ventilation. Even better news, First Tunnels are offering a FREE sliding door upgrade with all complete Polytunnel orders placed by 31st March, saving upto £200.
