As needed
  • water dropWater

    The mum should be watered deeply, allowing the soil around it to become moist but not waterlogged. It’s best to water it early in the morning directly at the base to keep moisture off the foliage, which helps prevent disease. In general, the mum will need about 1 inch of water per week, but this can vary depending on climate and soil conditions. During hot spells or dry spells, you might need to water every other day. Always check the top inch of soil, and if it feels dry, it’s time to water.

  • sunLight

    Mums thrive best in full sunlight, receiving a minimum of 5 to 6 hours of direct sun per day. Placing Chrysanthemum 'Topsy' in a spot that receives early morning light is particularly beneficial, as it dries dew promptly, reducing the risk of fungal diseases. However, in very hot climates, providing light afternoon shade can help protect the plant from excessive stress.

  • thermometerTemperature

    Mums prefer a temperate climate and perform best when night temperatures are between 60 to 70 degrees Fahrenheit, and day temperatures are between 70 to 80 degrees Fahrenheit. They can survive in temperatures as low as 32 degrees Fahrenheit, but frost can damage the plant. The ideal growing conditions for mum include a location where the temperature does not exceed 90 degrees Fahrenheit.

  • scissorsPruning

    Pruning mums is important to maintain a compact, bushy shape and encourage more blooms. Pinch back the growing tips in the spring and early summer to promote branching, stopping by mid-July to allow flower buds to form. After flowering, you can cut back the stems to 1-2 inches above the ground to prepare the plant for winter. The best time for pruning is when the new growth reaches 4-6 inches in height.

  • bambooSoil

    Mums thrive in well-draining soil enriched with organic matter, such as compost or peat moss. A balanced pH between 6.0 and 7.0 is ideal for Chrysanthemum 'Topsy'. A mixture of garden soil, compost, and perlite or vermiculite in equal parts can create the best soil environment for these plants.

  • plantRepotting

    Chrysanthemum 'Topsy', or garden mum, should be repotted every 1-2 years to replenish nutrients and prevent overcrowding. The optimal time to repot is just after blooming, or in early spring before the growing season begins.

  • circleLife cycle

    Chrysanthemum 'Topsy' starts its life as a seed, which germinates in the right conditions of warmth and moisture to produce a small seedling with a pair of initial leaves. As the plant grows, it develops a vegetative structure with a robust stem and a series of leaves that engage in photosynthesis, leading to further growth. The chrysanthemum then enters a phase of budding, where flower buds form at the tips of the stems, preparing the plant for its reproductive stage. These buds blossom into the characteristic flowers that may come in various colors, and this blooming period can last several weeks, attracting pollinators. After pollination, the flowers produce seeds, which are dispersed by various means, including wind and animals, completing the reproductive cycle. Finally, in many climates, Chrysanthemum 'Topsy' enters a period of dormancy over the winter months, during which it may die back, but with proper care, it can regenerate from its root system the following spring.

      Spring-Early Summer

    • Chrysanthemum 'Topsy', commonly known as mums, can be propagated through the division of its root clumps, which is the most popular method for this plant. The ideal time for dividing mums is in the spring as new growth begins, typically after the danger of frost has passed. To propagate by division, dig up the entire plant when the new shoots are about 1 to 2 inches tall, and carefully separate the root clumps into smaller sections, each with several shoots and a portion of the root system. These divisions should then be replanted at the same depth they were previously growing, spaced about 18 to 24 inches apart (45 to 60 centimeters), allowing ample room for the new plants to grow and mature. Water the newly planted divisions thoroughly to help establish their roots in the garden.
