Bench notes

Care for this Pyrenacantha malvifolia 5 Gallon Pot.

Fat-stemmed, fat-rooted plants that store water for the dry season and grow in bursts. The rule at the bench: read the plant, not the calendar. Water when it is in leaf, stop when it is not.

Light: Bright light with several hours of direct sun on the foliage. Shade the caudex itself if it sits in afternoon sun; a sunburned caudex scars for good.
Water: Water thoroughly when in active growth and the mix has dried through, then nothing until it dries again. In dormancy, a light drink once a month at most, and only if the caudex softens.
Soil: Sharp-draining mineral mix: at least half pumice or scoria, the rest screened bark or coarse coir. Terracotta or an unglazed pot with one big drainage hole.
Dormancy: Most drop their leaves and stop for part of the year: winter for the summer-growers, summer for the winter-growers. Leaf drop is the signal to cut water, not a problem to fix.

Hardiness

Frost-tender as a group. Keep above 40°F, and keep the roots dry whenever nights fall below 50°F.

Feeding

Balanced fertilizer at quarter strength with every third or fourth watering while in leaf. Nothing while dormant.

Repotting

Every two to four years at the start of the growing season. Keep the caudex at the height it was; burying it deeper invites rot.

Watch for

A soft or wrinkled caudex in growth means thirst; the same in dormancy means rot, and the answer is dry air, not water. Mealybugs hide in the crown and under the lip of the caudex.
