I'm taking a new approach to the Dandelion problem.
When we first moved in here there were very few Dandelions. But within a year or two they were starting to appear along the driveway, then around the house, then in the garden..... Darn things spread like, well, like Dandelions.
Every Spring I tried to get ahead of them by weeding like mad but it hasn't worked. Full forward assault doesn't work if the enemy outnumbers you 1000 to 1. I couldn't dig them fast enough - by the time I had part of the garden cleared the others had all gone to seed.
I tried a flank attack using that vinegar/soap/salt spray but that was too hard, too slow, and too expensive.
A rear-guard attack by digging them out later in the season didn't do much good either because they had already spread their seeds far and wide.
So I'm going aerial.
I just spent a couple of hours pulling all the flowers and buds off all the Dandies around the house and garden and up the driveway a piece. Hah. Now they can't go to seed and I'll have all summer to dig out the plants. I know there will be more flowers in a day or two, but I'll fly over again nipping them off too. I tried to get as many buds as I could but the really small ones were too short to grab and I didn't want to pull the whole plant. If you do that the flowers still ripen seeds and you have a big pile of stuff you can't compost. This way, with the flowers pulled off short, no seeds will form.
So if I can't be faster than a Dandelion, or meaner than a Dandelion, or tougher than a Dandelion, maybe I can be smarter than a Dandelion!
