How much exposure to cold and at what temperatures is required to induce flowering of a hollyhock plant?
Hollyhock plants (Alcea) typically require a period of winter dormancy and exposure to colder temperatures to induce flowering. This dormant period is essential for triggering the flowering process. Here are some general guidelines regarding cold exposure and temperatures for hollyhocks:
1. Chilling requirement: Hollyhocks often have a chilling requirement, which means they need a certain duration of exposure to cool temperatures to initiate flowering. This chilling period simulates the transition from winter to spring and is crucial for breaking dormancy.
2. Cold temperature range: The specific temperature range required to induce flowering in hollyhocks can vary, but it is typically within the range of 4°C to 10°C (39°F to 50°F). These cooler temperatures signal the plant that it's time to exit dormancy and start growing again.
3. Duration of cold exposure: The duration of cold exposure necessary for flowering can vary depending on the cultivar and environmental conditions. It typically ranges from a few weeks to a couple of months. During this time, the hollyhock plant accumulates the necessary chilling units needed to initiate flowering.
4. Transition to warmer temperatures: After the required chilling period, hollyhocks need a transition to warmer temperatures for active growth and flowering to occur. As temperatures rise, the plant resumes its growth cycle, producing foliage, stems, and eventually flowers.
It's important to note that while cold exposure is necessary for inducing flowering in hollyhocks, excessive or prolonged exposure to freezing temperatures can be detrimental to the plant's health. Therefore, providing the appropriate duration of cold exposure within the recommended temperature range is crucial for optimal flowering.
