Troubleshooting
Boojum Tree problems — and how to fix them
Boojum Tree (Fouquieria columnaris) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
The near-universal cause of death in cultivation. Because growth is so slow, collectors are tempted to water more frequently — this is fatal. Water only when the substrate has been bone-dry for at least 1–2 weeks and temperatures are warm.
Sunburn on relocation
Plants moved suddenly from indoor conditions to full outdoor sun can sunscald. Acclimatise gradually over 2–3 weeks by increasing sun exposure incrementally.
Extremely slow growth discouraging collectors
In temperate climates without full desert sun and heat, growth may be as little as 1–2 cm per year. Supplemental heat mats and high-intensity grow lights during winter help maintain a faster pace.
