How often to water Autograph tree
- Spring–Summer (Mar–Sep)
- Every 7 days
- Its thick leaves hold water, so as a guide water thoroughly only after the soil has dried out.
- Autumn (Oct–Nov)
- Every 10 days
- Water about two to three days after the soil dries.
- Winter (Dec–Feb)
- Every 14 days
- Water sparingly about a week after the soil dries.
Light and placement for Autograph tree
A bright window is about right, and once acclimated it generally takes full sun outdoors; it tolerates shade, though in dim light the leaves shrink and the branches stretch, and a plant grown indoors scorches if suddenly put in midsummer sun.
Overwintering Autograph tree
Overwintering guide: 5°C (41°F) or above
Move it to a bright spot indoors when nights fall below about 10°C; it tolerates roughly 5°C, kept on the dry side and away from cold windows and heater draft.
Fertilizing and repotting Autograph tree
Fertilizer
Slow-release fertilizer about every two months from May to September; it grows slowly, so keep doses modest, and give none in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Autograph tree
- Overwatering rots the roots and the leaves yellow and drop.
- In a dark spot the new leaves come out small and the branches stretch.
- Scale insects on the leaf undersides and stems leave a sticky residue.
Tips for growing Autograph tree
- The name comes from being able to scratch writing into the leaves, but the marks stay, so avoid it on a display plant.
- Dust settles on the broad leaves, so wipe them with a damp cloth now and then.
- Pruning the shoot tips in spring makes side shoots and a fuller shape.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
