Rebar garden arch11/16/2023 ![]() ![]() What this tells us is that an arch not much larger than a house doorway can support a vine over 5m long, and it only occupies a very small area on the ground where the vine is planted, which can be as little as 50cm x 50cm (around 20” x 20”). total length of an arch = (2 x length of vertical side sections) + (3.14 x 0.5 x width of arch).If we use the earlier example of a small 1m (3’) wide x 2.5m (8’) high arch and put these figures into the formula: The diagram below shows how an arch consists of two main sections, the pair of vertical sections at the sides, and the curved section at the top, and how their lengths are used in the calculation. The formula for calculating the total length of an arch = (2 x length of vertical side sections) + (3.14 x 0.5 x width of arch) To calculate the total length of an arch, we can simply use a tape measure, but when was the last time anyone did that? Arches are often dismissed as being small and insignificant, and without first considering the value of arches, there is no inclination to seek them out for measurement!Ĭalculations are useful for design purposes, we can use them to work out the size of an arch required to support a certain length of edible vine such as a grape of berry, or we can determine how much growing space an arch of a given size can provide. Where will I ever use this stuff? Well, life is full of surprises… Most people ignored maths at school, and glossed over geometry. How much growing area can a small 1m (3’) wide x 2.5m (8’) high arch, a little taller than a house doorway, actually provide? If we do the math, we might be in for a bit of a shock. How Much Growing Space Can Arches Provide?Īn arch at first glances would appear to offer very little growing space. Some of the best vertical gardening solutions can be so deceptively simple that it’s often overlooked! One of the least appreciated ways of growing edible climbers is over an arch, mainly because people don’t realize how much growing space is available on a relatively small archway. ![]() Gardeners are very resourceful, and in the gardening world there are many techniques which have been developed to take advantage of vertical spaces, such as espaliered trees grown flat against walls, even more compact columnar ‘cordon’ tree forms, and methods which rely on structures such as trellises and arbours. There are many ways to maximise the use of limited available space, and one of the best ways is vertical gardening, growing upwards rather than outwards! Small-space gardening is becoming increasingly popular as outdoor spaces and gardens get progressively smaller in urban areas. ![]()
