sunburn on Escobaria Missouriensis
Quick answer
If your Escobaria Missouriensis has sunburn, the most likely cause is: Escobaria missouriensis (Missouri nipple / Missouri foxtail cactus) is included in the cold-climate cactus book Chance (2012) and, like the other cold-hardy pincushion cacti, is easily sunburned when dormant or half-dormant tissue is exposed to strong sun it has not been acclimated to, especially during spring and autumn freezes and at higher altitudes where ultraviolet rays are stronger.
Start here:
- 1. Provide temporary shade for newly shipped or newly potted Escobaria missouriensis, using a rock, a flowerpot, or a small piece of paper tissue over the crown, until the root system has had time to develop and the plant is established enough to sit in direct sun.
- 2. Uncover any frost cloth, autumn-leaf mulch, or nursery cover gradually in spring rather than all at once on a sunny day, so tissues that have been kept dark all winter and may still be frozen are not hit by direct morning sun while they thaw.
