Bristlecones are native to western United States at high altitude, and can outlive any known organism on the planet. The current record-holder is a tree named Methuselah, which is believed to be over 4,700 years old! They need well-drained soil, and very little water. It'll be a challenge not to over-water these little guys.
Based on recommendations in online bonsai message boards, I used the following soil mixture:
- 40% Hoffman Bonsai Soil Mix (expanded shale, sand pebble, aged pine bark, TURFACE)
- 40% Desert Sand
- 20% Hoffman Cactus and Succulent Soil Mix
I'm hoping to see a few sprouts after a few weeks, but wouldn't be surprised if nothing happened between now and then. Bristlecones are very slow-growing trees, so this will really test my patience!
