There is nothing more beautiful than seeing a sea of flowers in your garden but if you don’t have room for traditional garden beds, why not grow your flowers upwards by using vertical gardening. Here are our tips to help you get the most flowers possible, so that you are looking out onto a hanging oasis.
To help your plants to thrive and thus produce the maximum amount of flowers, you need to make sure that you keep the nutrients up. Depending on the type of vertical garden you have, this can be as simple as adding slow release fertiliser to the soil. Otherwise, if your garden uses mainly water, you can mix nutrient solutions in the water to ensure that your flowers are well fed.
Plants need plenty of sunlight to flower properly but at the same time, you don’t want them to have too much sunlight as the plants may get too hot and the soil will dry out. Look for a wall that gets around six hours of full sunlight a day if possible – a north or north easterly aspect is ideal. If you don’t have an ideal wall, make sure that you select plants that can handle the amount of sunlight that the wall gets, as well as the amount of heat that the wall reflects.
While vertical gardening is one of the lowest maintenance forms of gardening, there are some tasks that you will still need to do in order to maximise flowering. The first is dead heading – removing flowers once that have started to wilt and die. Doing this will encourage more flowers to grow. After each flowering season, you should also prune your plants back according to instructions given with your plants. If your plants are annuals, you will likely have to replace them yearly – keep this in mind when selecting them.
If you are growing a vertical garden for the primary purpose of getting lots of flowers, it is worth taking the time to select your plants carefully. Your first consideration should be to choose flowering plants that are likely to thrive in your garden’s aspect. The next is to consider the plant’s root system – you don’t want something that is too vigorous or that develops a large root system. Some flowering plants that do really well in vertical gardens include climbing roses, miniature roses, petunias, marigolds, pansies, sweet pea, nasturtiums, jasmine, wisteria, daisies and so on. Also try and group together plants that have similar watering requirements as this will make keeping the plants healthy so much easier.
