Montbretia 'Jim Taggart' Crocosmia 'Jim Taggart'

Water

Montbretia should be watered deeply once a week, providing about one inch of water each time to encourage deep root growth. During hot or dry periods, the frequency may increase to twice a week. It's essential to allow the soil to dry out between waterings to prevent waterlogging, which can lead to root rot. When watering, aim to provide enough water to soak the roots by applying approximately 0.5 gallons around the base of the plant, avoiding wetting the foliage to minimize the risk of diseases.

Light

Montbretia thrives in full sunlight conditions where it can receive at least six hours of direct sunlight daily. The best spot for planting Montbretia is in a well-lit location that is not shaded by larger plants or structures, as full sun encourages robust growth and optimal flowering.

Temperature

Montbretia prefers temperatures between 60°F and 90°F but can survive minimum temperatures down to about 20°F during its dormant period in the winter. The ideal temperature range for active growth and blooming is between 70°F and 85°F. It is important to protect the plant from frost, which can damage the foliage and flowers.

Pruning

Montbretia benefits from pruning to remove faded flowers and encourage a second bloom. Deadhead spent blossoms regularly during the flowering season. Once flowering has ceased, usually in the late fall, cut the foliage back to within a few inches of the ground. Pruning in early spring to remove any winter-damaged foliage is also recommended, as it promotes healthy growth for the upcoming season.

Cleaning

As needed

Soil

Montbretia (Crocosmia 'Jim Taggart') thrives in well-draining, fertile soil with a slightly acidic to neutral pH of around 6.0 to 7.0. A good mix for this plant would be a combination of loam, compost, and some coarse sand to aid drainage. Adding peat or leaf mold can help to maintain the desired pH level and provide the necessary nutrients for vibrant growth.

Repotting

Montbretia typically does not require frequent repotting. It should be repotted every 2-3 years or when the clumps become too crowded. Ideally, divide and repot in the early spring just before new growth begins.

Humidity & Misting

Montbretia prefers moderate humidity conditions but is generally tolerant of a wide range of humidity levels found in typical outdoor environments. Consistency is key, and this plant does not require any special humidity considerations when grown outdoors.

Suitable locations

• Indoor

  Place Montbretia in bright, indirect light with good airflow.

• Outdoor

  Plant in full sun to partial shade; ensure well-draining soil.

• Hardiness zone

  5-9 USDA.

Life cycle

Crocosmia 'Jim Taggart', commonly known as Montbretia, begins its life as a corm, a bulb-like underground storage organ. In early spring, it starts its growth cycle by sending up shoots that develop into long, sword-shaped leaves. By mid to late summer, these leaves are followed by arching stems adorned with vibrant, funnel-shaped flowers, attracting pollinators to the garden. After flowering, the plant sets seed, which can be dispersed to propagate new plants, although the reproduction is mostly done by dividing the corms, which multiply underground. As autumn approaches, the leaves and stems die back with the first frosts, and the plant enters a period of dormancy over winter. In the following spring, the cycle resumes as the corms regenerate, sending up new shoots to begin the process anew.

Propogation

• Propogation time

  Spring to Summer

• Propogation: Crocosmia 'Jim Taggart', commonly known as montbretia, is most frequently propagated by dividing its corms. The best time to undertake this method is in late winter to early spring, just before the growing season begins, when the plant is dormant. To propagate montbretia by division, carefully dig up the clump of corms and gently separate them, ensuring each division has at least one growth point. The individual corms can then be replanted immediately at a depth of about 3 to 5 inches (7.6 to 12.7 cm) and spaced about 6 inches (15.2 cm) apart, in well-draining soil where they will receive full to partial sunlight. Water the newly planted corms thoroughly to establish a good root system.
