Every gardener is annoyed by weeds in their garden, and different gardeners often have very different approaches for controlling them. It’s not unusual for gardeners to have strong disagreements over weeds.
The Reasons for Having Weeds
Weeds are actually an important part of your garden’s ecosystem, and it’s impossible to get rid of them completely without damaging your garden. Many people mistakenly look at weeds in their neighbors garden, and think if their neighbor would just take care of them their own weed problem would go away.
The truth is most weeds come from seeds that are already in the ground, and have been there a very long time. Studies have shown weed seeds can survive in the ground hundreds of years or longer. As gardeners disturb the ground in their garden, they bring seeds up to the surface, which in turn grow.
All gardeners know that weeds don’t grow randomly, and it’s generally possible to identify 4-5 different weeds that account for the majority in their garden, and also that weeds favor different areas of the garden. There’s a very important reason for this. Weeds actually repair your garden.
For example, if you have too much nitrogen or potassium in your garden, stinging nettles may grow. As they grow, they will consume the nitrogen and potassium, and try to bring your garden into a healthier balance. You will get particular weeds if your soil is compacted, too wet, lacking nutrients, and so on. In each case the weeds will work to correct the imbalance or problems. Gardeners who use weed killer like Round Up in their gardens will notice they get Mare’s Tail, and this is for the same reason, to repair the damage caused by the chemical.
Repairing your garden with weeds alone is usually impractically slow. They are however very good as indicators. Letting some weeds grow, together with other organic methods, can be a very effective way of keeping your garden in balance, and over time weed problems tend to go away on their own.
On the other hand, if you keep fighting the weeds, you end up damaging your garden and you end up being unaware of fundamental problems that could possibly be easily corrected.
The View With Chemicals
People who use chemicals to control weeds in their garden sometimes have a completely distorted view of the world. The often blame the seeds blowing into their garden from nearby weeds as the source of their problem. They believe the best state of affairs is for all weeds to be destroyed, and only their desired plants to be growing. They often look further and further away from their garden.
Some gardeners even think some weeds are worse than others. For example nettles because they sting, or thistles because they prick you. I even knew a gardener that thought all yellow flowered weeds were bad. I guess because there was Round Up ready rape(canola) growing wild, and he had to pull this out by hand.
Some farmers have a similar view. For example, on one hand using chemicals to destroy a disease on their own crop, then looking for the same disease on neighboring (organic) crops and blaming those gardeners or farmers for causing the problem.
Invasive Species
The arguments are often mixed with racism. In fact the Dutch language has a term ‘alloctone’, that can refer to either an invasive species or a person of foreign origin. Some people even think it’s possible or desirable to completely eliminate invasive species, maybe with gene drives.
Of course reasonable steps should be taken to prevent invasive species from spreading.
The reality is invasive species are an indicator of very serious environmental problems that need to be addressed. There are natural methods for control, like introducing natural predators or commercial harvesting. Attempting to remove them completely in an unnatural way can’t be done without further damage to the ecosystem, and shouldn’t be attempted.
