The burning bush was in the desert at the top of a cliff.
(Subjected therefore to wind storms and fine particles of sand flying around)
From Wikipedia's article on St Elmo's Fire:
"Physically, St. Elmo's fire is a bright blue or violet glow, appearing like fire in some circumstances, from tall, sharply pointed structures such as lightning rods, masts, spires and chimneys, and on aircraft wings. St. Elmo's fire can also appear on leaves, grass, and even at the tips of cattle horns.[3] Often accompanying the glow is a distinct hissing or buzzing sound."
Therefore, in my opinion, it is safe to assume the burning bush that burned without burning up was subject to the phenomena known as St. Elmo's Fire.
My second response would be DAMP soil, you don't need to be starting any brush fires...
Loam soil is considered the best type of soil for planting crops because it has a balanced mix of sand, silt, and clay which provides good drainage, retention of moisture, and nutrients for plant growth.
Topsoil is generally best, however soil type and quality will depend largely on the types of crops you're raising. Soil PH is a big factor in determining which plants will do well in your climate and soil type.
Loam soil is considered the best type of soil for growing plants. It contains a balanced mixture of sand, silt, and clay, providing good drainage, moisture retention, and nutrient availability for plants to thrive.
Loam soil is considered the best type of soil for growing most types of plants. It is a mixture of sand, silt, and clay, providing good drainage, moisture retention, and nutrient levels. It offers a balanced environment that supports healthy plant growth.
Loam soil is considered the best for growing wheat because it has a good balance of sand, silt, and clay, providing good drainage, nutrient retention, and root penetration. Wheat prefers well-draining soil that is rich in organic matter and has a slightly acidic to neutral pH level.
