Troubleshooting
Brush-tipped Bursera problems — and how to fix them
Brush-tipped Bursera (Bursera penicillata) 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 and caudex rot
Overwatering, especially during dormancy, is the primary killer. A soft, mushy base with discolouration is the warning sign. Unpot, trim all rot, dust with sulphur powder, dry for several days, and replant in fresh dry gritty mix.
Reluctance to break dormancy
If the plant stays leafless well into spring, it is likely kept too cool or too dark. Move to a warm (minimum 18 °C), bright sunny position and resume light watering; buds typically swell within 2–4 weeks.
Scale insects on bark
Brown or tan waxy bumps on stems and the caudex are scale. Scrape off with a soft brush or cotton swab dipped in isopropyl alcohol; follow up with a systemic insecticide if the infestation is severe.
