Doing a burn is not necessary to maintain a healthy garden.
The primary benefit of burning is to rid the garden's thatch build
up. Several years may pass before thatch build up becomes a
problem in your garden.
When thatch does smother the ground; rather than setting a fire,
the thatch can be finely chopped by mowing. Folow by raking off
the dead vegetation debris.
Burning does add carbon into the soil which will benefit some
flowers, but not all species respond so positively to regular annual
There is a paramount draw back to burning in late fall, winter, or
early spring. Fire can poise a hazard to property. A person
unexperienced with burning an area is at risk for making mistakes.
Unfortunately, wind can shift or the dried vegetation may generate
its own momentum and take off burning into an place you do not
want it to go. For example, a dilapidated hog house goes up in
flames. Oops, that is where $20,000 of hard wood beans suitable for
sale as fireplace mantles was stored.
There are many calamitous stories. The short of it, fire is a
dangerous tool to use as a remedy for getting rid of dead vegetation.
Instead, be safe and mow and rake.
One last disadvantage, fire toasts the wintering deep sleeping insects
settled snugly among the wildflowers.
