Fertilization
Although Caucalis arvensis Huds. does not require a lot of fertilizer, it is essential to add some nutrients to the soil to ensure healthy growth and vibrant flowers. Before planting, it is recommended to mix some compost or well-rotted manure into the soil. You can also feed the plant with a balanced fertilizer once a month during the growing season.
Pruning
Caucalis arvensis Huds. does not require pruning as it is a self-seeding plant. However, you can deadhead the flowers to promote additional blooms. You can also cut back the plant after blooming to stimulate new growth and prolong the blooming season.
Propagation of Caucalis arvensis Huds.
Caucalis arvensis Huds. is propagated through seeds. It is a self-seeding biennial or annual that readily reproduces if allowed to set seeds. The plant produces seeds in the second year, which are small and have a spiny coating that sticks to fur, clothing, and shoes. The seeds can remain viable in the soil for several years.
Seed Collection
To propagate Caucalis arvensis Huds., collect the seeds when they are ripe in the fall. Identify the mature seed heads, which are dry and brown, and cut them off with pruning shears. Place the seed heads in a paper or cloth bag and label them with the date and location.
Seed Treatment
After collecting the seeds, they should be dried and stored in a cool, dry place until they are ready for planting. The seeds do not require stratification or scarification. If the seeds are not collected when they are ripe, they may need to be scarified to break the hard seed coat, or they may not germinate.
Seed Sowing
Plant the seeds in the fall before the ground freezes, or in the spring after the last frost. Sow the seeds in rows or broadcast them over the soil. Cover the seeds with a light layer of soil, and water well. The soil should remain moist until the seeds germinate in 7-21 days.
Transplanting
Caucalis arvensis Huds. grows best in full sun or partial shade and well-drained soil. When the seedlings have 2-3 leaves, thin them to 6-12 inches apart to give them room to grow. Transplant the seedlings when they are 6-8 inches tall to their permanent location.
Conclusion
Propagation of Caucalis arvensis Huds. is easy and straightforward. Collecting, drying, and storing the seeds is the first step. Sowing the seeds and transplanting the seedlings are also important. Follow these propagation methods to ensure a successful crop of Caucalis arvensis Huds.
