Fertilizing Methods for Coleus: What Fertilizer to Apply at the Right Time

Although coleus has a relatively low demand for fertilizer, we cannot skip fertilizing entirely when growing it, otherwise it will develop fewer leaves, yellowing, or wilting due to nutrient deficiency. So how should coleus be fertilized? Let me give you the answer.

How to Fertilize Coleus Properly

I. Fertilizer Selection

When fertilizing coleus, we first need to know what kind of fertilizer it needs. First, it needs a base fertilizer, whose role is to make the soil more fertile; second, it needs nitrogen, phosphorus, and potassium fertilizers. Nitrogen is a component of the living cells of coleus, and plant growth requires a large amount of nitrogen.

Phosphorus is one of the main nutrients that promote flowering in coleus. It also participates in photosynthesis, respiration, and cell division, making it one of the essential elements. Potassium fertilizer is related to the metabolism of coleus, so none of the three elements can be missing.

II. Fertilizing Methods

1. Apply base fertilizer before potting

Base fertilizer is mainly used at the time of potting, because it needs to be applied at the bottom of the soil or mixed into the soil. Base fertilizer is generally mainly organic fertilizer and bone meal, and it can also be mixed into the soil. However, note that more base fertilizer is not necessarily better; the amount used is generally one-tenth of the soil.

2. Apply nitrogen fertilizer during the growing season

As we mentioned earlier, nitrogen is the main component of the living cells and chlorophyll of coleus, and it is the nutrient element that any plant needs most during growth. So how should coleus be fertilized during the growing season? A dilute nitrogen fertilizer should be applied 1-2 times per month.

3. Apply phosphorus fertilizer before the flowering period

Scientific research has found that the phosphorus content in plant seeds is very high, so phosphorus fertilizer has the effect of promoting plant flowering and fruiting. Therefore, before the flowering period of coleus, 1 application of phosphorus fertilizer can be given as a top dressing. In addition, after pruning, phosphorus fertilizer can also be applied as a top dressing to promote cell division and enlargement, which helps new branches grow.

Precautions for Fertilizing Coleus

1. Do not apply excessive nitrogen fertilizer

During the growing season, apply nitrogen fertilizer once every 15-20 days. When fertilizing, use mainly dilute fertilizer water and do not apply excessively, otherwise the chlorophyll content will be too high, causing the leaves to become thick and lack luster.

2. Water appropriately after fertilizing

If the fertilizer is directly scattered on the potting soil, it needs to be watered appropriately after fertilizing. The principle for watering is to water thoroughly, meaning both the upper and lower parts of the soil are moistened, so as to reduce excessive concentration on the soil surface and at the same time allow the fertilizer to enter the interior of the soil more quickly and be fully absorbed by the roots of the coleus.

Does Coleus Need Fertilizer? What Fertilizer to Apply?

Coleus is a foliage ornamental flower and can also be used as foliage in flower baskets and bouquets. It blooms in summer and autumn, has panicles, and small flowers that are light blue or tinged with white, giving it high ornamental value. So does coleus need fertilizer? What fertilizer should be applied? Today, the editor of China Agrochem Business Network will share this with everyone.

Coleus is relatively easy to grow and very easy to keep alive. It is suitable to mix thoroughly half fully decomposed humus soil and half plain sandy soil and put it into a seedling pot. A dilute liquid fertilizer can be applied as a top dressing throughout the year, but not too much; use the method of small amounts applied multiple times. Coleus does not have high fertilizer requirements. During the growing season, apply a dilute fertilizer mainly based on nitrogen fertilizer 1-2 times per month.

What Fertilizer to Apply to Coleus:

When fertilizing coleus, pay attention to the rational use of nitrogen, phosphorus, and potassium, and do not arbitrarily favor one fertilizer. Today, the editor will recommend a relatively easy-to-use fertilizer to everyone - Hengfeng special fertilizer for flowers. It is a household granule type, not only simple and convenient to use, but its unique formula provides sufficient nutrients and growing space for the growth of coleus. Applying this fertilizer into the potting soil of coleus can not only ensure comprehensive nutrition, but also keep the leaf color more beautiful.

That is all for the fertilizing methods for coleus. I hope this article is helpful to everyone.

How to Grow Coleus: Cultivation Methods and Precautions for Coleus / The Environment Must Be Suitable

We know that coleus has many uses and functions, and ornamental value is one of them. To make it more beautiful, you need to master scientific planting methods. So how should coleus be grown? Let us look at the cultivation methods and precautions for coleus.

How to Grow Coleus

Before cultivating coleus, you need to understand its growth habits. Coleus is a plant that likes warm and humid environments. It has relatively strong adaptability and likes sufficient sunlight, but it also has a certain tolerance for shade. In winter, as long as the temperature is not lower than 10 degrees, it can overwinter smoothly.

Cultivation Methods and Precautions for Coleus

1. The most suitable soil

Coleus can adapt to many soil environments; for example, it can grow normally in both acidic and alkaline soils. However, its most suitable soil is fertile, loose, well-drained acidic soil rich in humus, so garden soil, leaf mold, and river sand are the best.

2. The most suitable light

Since the ornamental value of coleus mainly comes from its leaves, if the leaf color is bright, the ornamental value is high; conversely, if the leaf color is dull, it is not as beautiful. To make the leaf color bright, suitable light is needed, and its most suitable light condition is soft and sufficient light. In summer, avoid direct sunlight, and at the same time note that the environment should not be too shady.

3. The most suitable temperature

Coleus likes a warm environment. Its most suitable growth temperature is 18-25 degrees. In winter, the temperature should be kept above 10 degrees. Too low a temperature will cause the leaves to turn yellow, and an environment of 5 degrees will freeze the plant to death.

4. The most reasonable watering

Coleus is a plant with relatively high water requirements. Lack of water will cause slow growth and dull leaves. So in terms of watering, how should coleus be grown? Therefore, watering must be appropriate, mainly ensuring that the soil is moist; creating a humid environment is very important.

5. The most scientific fertilizing

In the cultivation methods and precautions for coleus, its demand for fertilizer is not high, but ensuring the nutrients needed for growth is still relatively important. Therefore, when planting, base fertilizer needs to be applied at the bottom of the soil; and during the growth period, applying nitrogen fertilizer 1-2 times per month can promote leaf growth.

Precautions for Growing Coleus

1. Do not let the environment be too dark

Many flower enthusiasts keep coleus indoors in pots. If this is the case, be sure to note that the environment should not be too dark, otherwise the leaves will lose their luster and the leaf color will not be rich enough.

2. Do not fertilize or water too much

Although coleus likes a humid environment, do not water too much. The principle is that there should be no standing water in the pot, and do not continue watering while the soil is still moist. After watering, wait 3-4 days until the soil is dry before watering a second time.

3. Pay attention to keeping warm in winter

Coleus has relatively poor cold tolerance. If the temperature is below 5 degrees, frost damage may occur. Therefore, in the cold winter, pay attention to changes in temperature and take warm-keeping measures early, such as moving it back indoors or covering it with a plastic bag.

How to Grow Coleus Well

To grow coleus well, in addition to understanding the above points, you also need to prune it at the right time and do a good job of pest and disease prevention. For example, pinch the top during the seedling stage, and later, when the branches and leaves are too dense, thin them out by pruning; for pests and diseases, carry out prevention in ordinary times.
