Light Requirements
Taraxacum croceum requires full sun to partial shade for optimal growth and development. It can tolerate some shade, but plants grown in shady conditions may produce fewer flowers and have a less sturdy structure.
Temperature Requirements
This plant can adapt to a wide range of temperatures. However, it prefers a cool to mild climate and can tolerate temperatures as low as -30°C during winter dormancy. During the growing season, it can survive in temperatures ranging from 10-20°C.
Soil Requirements
Taraxacum croceum prefers well-draining, loamy soil with a slightly acidic to neutral pH range of 6.0 to 7.5. The soil should be free from rocks and debris to allow for healthy root growth. Organic matter, such as compost, can be added to the soil to improve fertility and moisture retention.
Cultivation Methods for Taraxacum croceum auct. non Dahlst.
Taraxacum croceum auct. non Dahlst. or the yellow dandelion grows well in natural environments, but it can also be cultivated. The most common method to grow the plant is to sow its seeds during the early spring in well-draining, nutrient-rich soil. The soil should be tilled shallowly so that it can loosen up and a seedbed can be prepared easily.
Once the seedbed is ready, sow the seeds at a depth of about 1/4 inch. Cover the seeds with soil, firming it gently, and irrigate appropriately. The seedlings should emerge in about ten days, after which they can be thinned to a spacing of 6-8 inches between them.
Watering Needs
Taraxacum croceum auct. non Dahlst. prefers moist soil, but it is essential not to over-water it. Aim to water the plant regularly but infrequently, giving the soil enough time to absorb the moisture before the next watering. If the plant is grown in conditions of high humidity, reduce the watering to allow for the soil to dry up a little bit to prevent root rot.
Fertilization
Fertilization is essential to keep the plant healthy and care for. As soon as the first flush of blooms has faded, apply a balanced, all-purpose fertilizer around the base of the plant. It will replenish the nutrients that the plant used to produce flowers. Avoid over-fertilizing, as it may lead to leafy growth at the expense of blooms.
Pruning
The yellow dandelion does not require much pruning. You can remove flowers as they start to die out. You can also cut off the entire stem and flower head once the bloom has faded to prevent the plant from self-seeding and promoting the growth of new flowers. If the plant starts to spread beyond the preferred growing location, cut off any part of the root system that extended beyond the desired location.
Propagation of Taraxacum croceum auct. non Dahlst.
Taraxacum croceum auct. non Dahlst. can be propagated through a variety of methods. The most common methods include:
Seed Propagation
The seeds of Taraxacum croceum auct. non Dahlst. can be sown in the fall or early summer. The ideal time for sowing is in late autumn when the soil is moist. Sow the seeds in a soilless mix, and keep them moist. Germination will occur within 10 to 14 days.
Division Propagation
Taraxacum croceum auct. non Dahlst. can also be propagated through division. Divide the plant during spring or fall, make sure each division has some root and a few leaves. Gently tease the roots apart before replanting. Ensure the soil is moist and well-draining and the plant is situated in an area with partial shade.
Vegetative Propagation
Another popular method of propagation is vegetative propagation. This is done by taking stem cuttings from the parent plant and rooting them in soil. Take the cuttings in the late spring or early summer. Cut a stem section that is about four inches in length, ideally with some leaves. Remove the lower leaves and place the cutting in a pot with moist soilless mix, and keep it moist. Rooting will occur within 4-6 weeks, after which it can be transplanted into a larger pot or into the garden.
Propagation of Taraxacum croceum auct. non Dahlst. can be a rewarding experience, giving gardeners more opportunities to enjoy the beautiful yellow flowers and bright green leaves. Choose the propagation method that works best for you, and enjoy watching the plant grow and develop over time.
