I've heard accounts of sawtooth oaks producing in eight years. Beech trees are one of the slowest trees to produce, and chestnutsshould produce in less than ten years. If you are impatient buy some hazelnuts, and some dwarf apple trees; they should produce in 3-5 years. But, you must consider that you are planting on a dry rocky area so don't expect miracles.

I know he said "quick mast" Crigg, I was thinking longer term. My late grandfather planted 3 or 4 beech right in front of his house when he built it back in the late 30s because he loved squirrel hunting, by the time I was a kid in the 60s those trees were gynormous and thick with squirrels.

Beech like Kevin mentioned or Hickory, Walnut andPecan
