Winter Care for Star Jasmine Indoors (Zone 5)

A reader in Zone 5 has a 3-foot Star Jasmine on a trellis in a 12-inch pot, bloomed all summer in morning sun. Asks about repotting, soil, and winter light needs.

Do Not Repot

Repot only in spring. 12-inch pot is adequate indefinitely.

Indoor Care

Sunniest south window, drapes open all day.
Fertilize regularly except Dec/Jan.
Blooming will slow in short days.
Spring: add 1 tbsp Epsom salts (magnesium sulfate) to restart blooming.
Water when top 1–2 inches dry. Overwatering kills more than underwatering.
