Disclaimer: this is a tongue-in-cheek blog post. Never ruin someone’s garden.
If you hang out online long enough, you will run into some crazy questions. Like this one: how do you ruin someone’s garden? Aha. Let’s have some fun.
For sure the quickest way to ruin someone’s garden is to cover it in copious amounts of weed killer. I don’t want to name any one specific product but there are many available, they’re cheap and they work. If you soak everything thoroughly, you’re guaranteed success. Usually in a matter of hours.
Warning: cosmetic pesticide use isn’t allowed in British Columbia. Of course, this is a tongue-in-cheek blog post. I’m not expecting anyone to actually run out and ruin a garden but if you do, do it under cover of darkness.
You might also consider applying a pre-emergent granular product that forms a barrier on top of the soil. It will sterilize your garden soil and affect the most important part of garden soil: the life in the soil.
The discussion used to be about soil content. How much organic matter is in the soil, etc. But now we’re finding out that the life in your soil is crucial to success. You can quickly ruin a garden by affecting the life in its soil.
Dumping fast-germinating grass seed onto someone’s garden would also be a nightmare because you’d have to weed it out. And that’s not fun.
This is actually a thing in the landscaping industry. When company A loses a maintenance contract to company B, they dump a lot of expensive grass seed into beds just to mess with the new landscapers moving in. It’s hard to believe, I know.
You can also ruin a garden by not weeding. Allow all weedy plants to flower and produce seeds. Since weeds are opportunistic colonizers they usually produce lots of seeds. So let them produce their seeds. They will accumulate in the soil and cause headaches for years to come.
There you have it. I hope that whoever asked the question online was kidding because need healthy gardens. One book I recommend is Dr. David Goulson’s The Garden Jungle. He wants you to stop worrying about global climate emergencies. Start with your own garden.
