Fringed Rue Care
Ruta chalepensis
A very drought-tolerant, aromatic shrub that likes full sun and well-drained, poor soil. It is used in traditional medicine, but contact with the skin followed by sun exposure can cause dermatitis, so it should be handled with gloves.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Pruning: Not done; the main pruning should wait until spring.
- Pests & diseases: Against the risk of root rot, make sure the soil is free-draining.
- Pruning: Toward the end of the month, just before new growth starts, rejuvenate the plant with a hard prune of two-thirds.
- General care: For new plantings, improve drainage by adding sand or gravel to the soil.
- Frost risk: Protect newly planted seedlings from severe frosts.
- Watering: Only for newly planted seedlings, 5-10 L/week if it stays dry; reduce if there is rain.
- Pruning: Prune just before the shoots break. Because flowers form on this year's new shoots, hard pruning increases flowering.

- General care: It opens yellow flowers. Its leaves can be a food source for swallowtail butterfly caterpillars.
- Pruning: Cutting faded flowers (deadheading) makes the plant look neater.

- Watering: In a long drought, water deeply once a month.
- Pruning: After flowering, a light pruning can be done.
- General care: Seed capsules begin to form.
