Protecting polytunnels against the wind is one of the duties that one should contemplate even before setting up the structure. First and foremost, remember that we are not talking here about gentle breezes, but strong winds, storms and even hurricanes. These difficult weather conditions usually appear as we get closer to spring. A foil tunnel will be exposed to them many times. To ensure that the greenhouse does not get damaged, it is worth preparing the structure.
Protecting foil tunnels against wind, storm and hurricane
Polytunnels made of hot-dip galvanized steel with foil dug into the ground usually do not need additional stabilizers. In urban spaces, the addition of fences, trees, walls, buildings, etc. reduces wind pressure. This method of securing it to the ground is sufficient. However, there are locations where weather conditions are much more unfavourable. In that case, pay attention to:
Foil on the gardening tunnel
The plastic foil should be adequatly stretched in order for the wind pressure to be evenly distributed over the entire structure. Over time, it will start to get loose, and tightening the cover systematically will be required. If abrasions and holes appear, they can be fixed with repair tape. In the event of major damage, replacing the entire sheet will be necessary. It is not worth purchasing low-quality covers, as they quickly lose their properties and need replacement after a season or two.
Door of the greenhouse
The entrance to the greenhouse will remain functional for years with proper maintenance. During caring duties, regularly lubricate hinges for an optimal opening process. It is worth checking whether the locking latch of the door has got a bit loose.
Location of a garden tunnel
By installing a polytunnel in an open space, there is no fear that something will damage it, but in practice, things are different. The close company of trees or shrubs can lead to tears in the cover in the event of branches falling. Therefore, it is recommended to build the structure somehow away from the vegetation. However, if this is not possible, try to eliminate weak branches, as well as those spreading over the greenhouse.
Anchors for a greenhouse
Digging the extra foil on each side is the standard solution to secure the structure. The cover supplied to the customer contains an excess of length for both walls, which is buried into the ground when the cover is in place. Optionally, you can also use anchors for hobby polytunnels. These are screwed into the ground, covered with soil, and then secured with a frame clamp.
Constructions for crops under cover
Protecting polytunnels against the wind is a sensible approach to face extreme conditions. It is always advisable to prevent and avoid situations that may damage the structure. A gardener who took all appropriate precautions against storms and strong winds can safely leave the structure unattended and relax.
