One of my favourites is when I decided to add a bit more colour to a newly planted perennial border (a 4 foot by 20 foot garden) and planted 4 packets of nasturtium seed.. not just any nasturtiums, but the vining types.. That's well over 100 vining nasturtium plants winding their way through my baby perennials.. their rampant vines also spilled out onto the pathways and eventually created a 4 x 20 foot mound of nasturtiums!! By the time I yanked them all out in mid-summer, the perennials were not impressed and I had a 5 1/2-foot tall pile of discarded nasturtium vines - it was bigger than me! (I can't believe I never got a photo of that pile!) At least it was a 'composting opportunity'! (In the worlds of Canadian garden personality Mark Cullen).
Of course, my biggest gardening blunder was starting my very first veggie garden in the shade!! Brilliant, eh? It was under the protective branches of a mature maple tree and although we only harvested one measly tomato, we did have a bumper crop of mid-summer greens that seemed to appreciate the respite from the heat..
What are some of the garden blunders that you've made..? Can you top mine?! I dare you.. :)
