How do I care for my rue plant?

Water the soil when it reaches about a finger's width away from the top of the pot. Make sure to water until the water starts to drain out of the bottom of the pot.

Fertilize with an organic, liquid fertilizer every two weeks during active growth in spring and summer. Reservoir or foliar fertilizers can be used at other times.

Feed with a half-dose of a high-nitrogen fertilizer once a month in winter.

Protect from frost and cold winds by bringing indoors before temperatures drop below 45 degrees Fahrenheit, preferably earlier if possible, or wrapping leaves in fabric that is warmed first so that the plant does not get shocked by the difference in temperature.

Mulch heavily to minimize moisture loss and protect roots.

Prune as needed to maintain shape and encourage growth of new stems or lateral branching; shearing is recommended over pinching since it encourages bushiness more than pruning back tops does, and there are no buds or flower clusters to remove with shearing. Prune when plants are dry.

Repot every two years in late winter using fresh, well-draining potting mixture.

Replace clogged or broken pots immediately because rue plants are sensitive to fluoride and salts in the water that builds up in those types of containers.
