They say you can't
really tell the effects of a flame weeder until the next day, so I went
back twenty-four hours later to see how Mark's test plot
fared. This was a moderate-level request of the tool --- trying to kill
perennial weeds, but low-lying, unvigorous ones that had popped up on a
fallow bed through the course of the winter.
Did the Weed Dragon do
the trick? No. Chickweed didn't even appear singed while the other
weeds looked no worse than they might after a very hard freeze.
I'd be curious to hear
from those of you who have already experimented with these devices. Are
they really just for tender new seedlings, or have you used a flame
weeder to knock out more heavy duty weeds?
In my backyard town gardens, flowers and veggies, I have too much goldenrod, Star of Bethlehem, other "weedy" flowers, and maybe too much lemon balm, celandine poppies, ground ivy and, of course, violets, esp in the "vegetable" garden. But the ground ivy is for the bees, and I can pull it up, which loosens the soil. Pulling up goldenrod I sort of look forward to! But dealing with poison ivy without getting rash from it, I have to use all my ingenuity. Not sure if the flame eater wd work on that, tho, since it might just inspire the roots, underground, to work harder. The flame eater might also kick in other weed regeneration, the way some burn-offs do...
I feel that some weeds do act as ground covers, esp when it gets too dry (next month).
I have found that any weeds that have a foothold in the garden are tough to eliminate with a flame weeder. Sometimes an extended burn will solve the problem but more often the old fashioned hoe is needed. The flame weeded is great once the bed is prepared and seeded. For three weeks after seeding the bed I use the flame weeder once a week to keep weed from getting a foothold. Use care not to burn newly emerging garden plants with the flame bouncing off the ground.
My first year owning a flame weeder I thought I wasted my money, after three years I am happy I own the tool. Flame the garden beds often and while weeds at just emerging, you will get ahead of the problem.
It's my understanding that flame weeders work a lot better if the flame is contained within a hood, or open-bottom metal box. And they are also only useful in killing just-emerged weeds, which is why they are used mostly to prepare stale seedbeds.
JM Fortier uses a flame weeder with a box the width of his beds, equipped with several flame nozzles.
