Chrysanthemum 'Pennine Jade' Chrysanthemum 'Pennine Jade' (29d)

Water

Mums, including the Chrysanthemum 'Pennine Jade', require even moisture and should not be allowed to dry out completely; however, they are also sensitive to overwatering which can lead to root rot. Water these plants deeply once a week, providing about one gallon of water per plant each time, ensuring that the soil is moist at about one inch below the surface. During periods of high heat or drought, you may need to water more frequently, possibly every 3-4 days, but always check the soil moisture first. Always water directly at the soil level to avoid wetting the foliage, which can promote disease.

Light

Mums thrive in full sunlight, so place your Chrysanthemum 'Pennine Jade' in a location where it will receive at least 6 hours of direct sunlight each day. An ideal spot would be in a south-facing garden or the brightest part of your yard. They can tolerate some light shade, especially in hotter climates, but too much shade can result in weak stems and poor flowering.

Temperature

Chrysanthemums, including ‘Pennine Jade’, prefer cooler conditions and can tolerate temperatures as low as 32 degrees Fahrenheit without damage. They thrive in a temperature range between 60 and 75 degrees Fahrenheit. They can survive temporary spikes in temperature but prolonged heat above 90 degrees Fahrenheit can be detrimental to the plant.

Pruning

Pruning mums like the Chrysanthemum 'Pennine Jade' encourages bushy growth and prevents legginess. Pinch back the tips of the stems in the late spring to early summer when they are about 6 inches long, leaving at least two to three sets of leaves on the shoots. Repeat the process every 2 to 3 weeks until midsummer for denser foliage and more vigorous flowering. The best time for final pruning or pinching is around the Fourth of July.

Cleaning

As needed

Soil

Chrysanthemums prefer well-draining soil with ample organic matter. A mix of two parts potting soil, one part peat moss, and one part perlite or vermiculite is ideal. The soil pH should be between 6.0 and 7.0 for optimal growth.

Repotting

Mums should typically be repotted every one to two years or when they become root-bound. The best time to repot is in the spring just as new growth begins.

Humidity & Misting

Mums thrive best in moderate humidity levels, around 40-60%. They can tolerate lower humidity, but consistent levels within this range help support robust growth.

Suitable locations

• Indoor

  Provide bright light, consistent moisture, and good air circulation.

• Outdoor

  Plant in full sun, shelter from strong winds, ensure soil drains.

• Hardiness zone

  5-9 USDA

Life cycle

Chrysanthemum 'Pennine Jade' starts its life cycle as a seed or a small cutting taken from a mature plant. Upon germination or root establishment, it enters a vegetative stage where it develops a rosette of leaves and begins to grow stems. As it matures, vegetative growth continues and the plant increases in size and develops a stronger root system. Following the vegetative stage, it enters the budding phase where flower buds start to form at the tips of the stems. This leads to the blooming stage, where the characteristic ornamental flowers open, showing varied colors and attracting pollinators. After pollination and flowering, the plant enters a senescence phase where it begins to die back, completing its life cycle, but it can also produce seeds for reproduction before this final stage.

Propogation

• Propogation time

  Early spring

• Propogation: Chrysanthemum 'Pennine Jade', commonly known as mums, is often propagated through division, which is a popular and straightforward method to multiply the plant. The ideal time for this process is in the spring when new growth begins. To propagate by division, carefully dig up the entire clump of the existing plant and gently separate the root ball into smaller sections, making sure that each division has a good amount of roots and a few shoots. Once divided, these sections can be immediately replanted in well-draining soil, spacing them about 18 to 24 inches (approximately 45 to 60 centimeters) apart to allow room for growth. Water the new divisions thoroughly after planting to help establish them. This method of division helps to rejuvenate older plants that may have become woody or less vigorous and also serves as a way to increase the number of plants in your garden or share with fellow gardeners.
