After receiving chrysanthemum seedlings, how do you plant, acclimate, and manage them for growth? This article provides a clear and detailed guide on planting, watering, acclimating, managing growth height, preventing diseases, and daily care for chrysanthemum seedlings (Part 1).
Begin by planting the newly received chrysanthemum seedlings in pots or in an open field. Mums like soft, fertile soil with good water permeability,Using a substrate like Aumabio’s π soil planting sponge is highly recommended, as it provides an ideal growing medium for chrysanthemums. π soil is a new type of plant cultivation medium, made primarily of coconut coir, humus, and peat, combined with clay, pine bark, and other agricultural and forestry by-products (making up approximately 90%). It’s also blended with polymer materials, making it lightweight with excellent water retention, drainage, and aeration, which are essential for plant growth and help prevent waterlogging.
Watering after planting is essential, especially if using peat soil, which requires multiple rounds of watering to be fully absorbed. Many people use peat soil that is dry to the touch; even if water flows out the bottom of the pot, this does not mean it’s fully soaked. Peat soil, when dry, has a poor absorption rate, so thorough watering typically requires 3–5 rounds to reach all layers. Some people find their seedlings wilt after planting, despite watering, due to insufficient moisture at the root level. To prevent this, it’s best to pre-moisten the peat soil slightly before planting so it will absorb water more readily afterward.
Using a fungicide such as carbendazim helps prevent bacterial diseases. After the initial watering, soak the soil with a diluted fungicide solution, which reduces the risk of bacterial infections and promotes healthy seedling growth. Fungicides like chlorothalonil or thiophanate-methyl are also effective if carbendazim is unavailable. Follow the product’s instructions for dilution, typically a 1500-2000 concentration is effective. While this step can sometimes be omitted in cooler, northern regions, it’s recommended in warmer, southern climates where bacteria are more active, as it helps prevent root rot, especially if overwatering is a concern. Fungicide treatment is highly beneficial for areas with frequent rainfall or those placing plants outdoors.
Following these three initial steps can help ensure nearly 100% survival rates for your chrysanthemum seedlings. In the next section, we’ll cover techniques for managing plant height, routine care, and additional growth tips to help your chrysanthemums thrive.
After the initial planting and thorough soaking, water sparingly but consistently, ensuring the soil stays moist but not overly wet. Frequency may vary based on climate, but generally, watering every 3–5 days is suitable once the soil is slightly dry.
Yes, alternative well-draining substrates like a mix of peat moss, perlite, and compost can also work. The key is to ensure the soil has good moisture retention without becoming compacted or waterlogged.
To harden seedlings, place them in a sheltered outdoor area for a few hours each day, gradually increasing their exposure to sunlight and outdoor conditions over 5–7 days. This reduces transplant shock and strengthens the seedlings.
Wait 2–3 weeks after planting before applying a balanced, diluted liquid fertilizer. For flowering plants, a phosphorus-rich fertilizer helps promote bloom formation. Apply fertilizer once every 2–3 weeks.
If root rot symptoms appear, remove affected soil and roots, and reduce watering frequency. Reapply fungicide if necessary and ensure the soil has proper drainage. Root rot is usually preventable with correct watering and good aeration.
