Cosmos is a tropical plant that is fast-growing and hardy. However, to ensure Cosmos grows strong and healthy, it needs sufficient nutrients. So, what kind of fertilizers do Cosmos plants prefer? This article will introduce 7 types of fertilizers suitable for Cosmos.
Organic Fertilizer
Organic fertilizer is one of the favorite fertilizers for Cosmos. It not only provides nutrients but also improves soil structure, increasing soil aeration and water retention. Commonly used organic fertilizers include well-rotted compost, chicken manure, and sheep manure.
Quick-Release Compound Fertilizer
Quick-release compound fertilizer contains multiple nutrients such as nitrogen, phosphorus, and potassium, which can be quickly absorbed and utilized by Cosmos. Especially during the rapid growth period of Cosmos, using this fertilizer can promote its fast growth.
Bio-fertilizer
Bio-fertilizer decomposes organic matter into nutrient elements through the metabolic action of microorganisms, which are then absorbed and utilized by Cosmos. This type of fertilizer can promote a more developed root system and increase the plant's disease resistance.
Phosphorus and Potassium Fertilizer
Phosphorus and potassium fertilizer is crucial for promoting flower bud differentiation and blooming in Cosmos. Using it can extend the flowering period, enhance the flower color, and make the blooms fuller and more vibrant.
Organic Liquid Fertilizer
Organic liquid fertilizer is a liquid fertilizer made by fermenting organic matter. Compared to solid organic fertilizers, it is more easily absorbed and utilized by Cosmos, resulting in more significant effects.
Seaweed Fertilizer
Seaweed fertilizer is rich in various beneficial components such as alginic acid, polysaccharides, and amino acids, which can promote the growth and flowering of Cosmos. It can also enhance the plant's stress tolerance and increase its resistance to pests and diseases.
Calcium and Magnesium Fertilizer
Cosmos requires large amounts of calcium and magnesium for its normal growth and development. Using calcium and magnesium fertilizer can ensure the healthy growth of Cosmos and enhance its resistance.
For Cosmos, choosing the right fertilizer is very important. Using the wrong fertilizer will not only waste resources but may also lead to poor growth or even death of the plant. It is hoped that the 7 fertilizers introduced in this article can help you better care for your Cosmos and allow it to grow healthy and strong.
