Perennial vegetables bring joy year after year
Edible perennial vegetables are receiving increasing attention, and for good reason - they have many advantages. They do not need to be replanted every year, they remain healthy and require little care. Perhaps you already have some in your garden, such as rhubarb or chives?
In permaculture, it is common to use them in forest gardens where one tries to mimic nature's own plant life - and that is because perennial vegetables are so easy to work with. They provide a good framework in cultivation and can easily be combined with annual plants.
Once the perennial vegetables have established themselves, it is often enough to just pull out some weeds and occasionally fertilize with organic material, such as composted manure, compost or manure water.
Another advantage is that they hardly need to be watered, since the root system is often large and only requires watering in the first year and during drought. This makes these plants very climate-smart.
Good resistance to diseases and pests
Hold up well against weeds
Lifespan and care
The vegetables that spread by seeds generally have shorter lives than those with proper root systems - trees and bushes live longest. It is safest to invest in varieties that suit your climate zone. Sometimes it is possible to create a microclimate where less hardy varieties can survive. What you should consider then is to give the plants a place with plenty of sun, shelter, and well-drained soil, such as in raised beds. In the first few years, most perennial plants should be harvested sparingly in order to establish themselves, but in the long run they provide large, reliable harvests. Furthermore, they appear early in the spring, so the harvest can often be earlier than with annuals.
Since many perennial vegetables are untreated and have been in nature for a long time, there are also many insects that feed on them. Therefore, they are an important part of biodiversity. So invest in some of them in the garden this year - they will give back a lot to you!
Tips: Feel free to grow perennial vegetables with cover cropping, as both plants and microorganisms benefit from it. There are also environmental benefits as it is water-saving and carbon dioxide stays in the ground.
