Adenium Care in Extreme Heat: Texas & Arizona Fall Conditions

Western — TX, AZ, NV, CA, NM, OK: Still baking. Westlake, Texas is under a heat advisory with highs of 100–101° this weekend and lows only dropping into the upper 70s — that's Dallas-area conditions right now, and Houston and San Antonio are riding the same pattern. Tucson is in its tail end of monsoon season, with highs in the 90s and thunderstorm chances running 20–60% through midweek. If you're in this region, you're not thinking about dormancy yet — you're thinking about heat stress and, where the monsoon is still active, about making sure your media isn't staying soggy between storms. That combination of high heat and periodic heavy rain is its own version of the rot risk the rest of us are watching for with cooler temps, just driven by different weather.

The full regional breakdown — with specific timing and application guidance for Cold Climate, Pacific Northwest, Gulf Coast, and Western growers — is at americanadenium.com.
