No space? It’s time to grow up with a vertical allotment
Short of space but want to grow your own edibles? The answer may be a vertical allotment of salad leaves, herbs and tumbling tomatoes and strawberries.
Planting your fruits, herbs and vegetables strategically can give you a year-round harvest, without having to join the waiting list for your local community allotment.
Keep it simple: “Create tiered shelving, in which case the easiest things to grow are microgreens and pea shoots and rocket,” says Mark Ridsdill Smith, author of The Vertical Veg Guide To Container Gardening (Chelsea Green).
“All the salads, plus herbs, would grow on shelves or on the rungs of an old ladder. That could be very productive in a small space.”
Try inbuilt watering systems:
If watering is too time consuming, an inbuilt watering system within your container may be the answer, says Matt Lindsay, general manager at green infrastructure specialists Growing Revolution (growing revolution.com). “Plantbox, for example, has an inbuilt watering system making it effortless to keep your plants happy and healthy and can be fixed to an external wall, balcony, or even indoors.”
You can buy planting troughs with water reservoirs which once filled can last a couple of weeks depending on location, weather and how thirsty the plants are.
Create a salad bar: “I’d raise a large trough – say 30cm deep and half a metre wide – up on bricks to create a salad bar,” says Chris Collins, head of horticulture at Garden Organic (gardenorganic.org. uk). “It needs to be south-facing or eastfacing. Sow in drills very quick crops such as
microgreens or rocket, pea shoots, so you have a fast turnaround. Put an obelisk in the centre of the trough and grow dwarf runner beans up that.” Make use of the wall space behind the trough by putting hanging basket brackets above it and planting trailing tomatoes or strawberries in the baskets.
Re-use plant pots: Use existing plant pots to grow your favourite fruits and vegetables to save
space and money on your vertical allotment, says Matt. “There are many vegetable varieties that can grow well in containers, including beetroot, herbs, runner beans and salad leaves.”
Make sure your pots are deep enough for your chosen plant and make a note of the specific care needed for each variety to give them the best possible chance of thriving, Matt suggests.
Use climbers: Climbing French beans and runner beans are ideal for growing in a vertical space, either in a pot up a bamboo wigwam or in the ground secured with ties against a fence or trellis, says Mark. Other tall plants, such as vine tomatoes with one main stem, can be secured to a wall with string, if you screw small eyes into the wall above an old nail.
“Squash grow on a vine so don’t take up as much vertical space. ‘Tromboncino’ squash is a good one because it tastes quite like courgettes. You can eat the fruits small or let them grow to a metre long,” adds Mark.
Make the most of windowsills:
Many herbs flourish on the windowsill. All you need is a spot that receives good sunlight, and you’ll be able to cultivate your own windowsill veg plot, says Lindsay. Have a go with herbs such as basil, thyme, or oregano.
