1. Principal cares
The Caladium is an indoor plant that requires proper care to maintain its beauty. Here are some tips to help keep your Caladium healthy:
- Light: Caladium needs indirect light to thrive. Avoid direct sunlight, as it can burn the leaves and cause spots.
- Irrigation: Make sure to keep the soil moist, but not waterlogged. Excess water can lead to mold and rot on the roots.
- Temperature: Caladium prefers warm temperatures, between 18 and 24 degrees Celsius.
- Humidity: The plant needs moderate humidity to keep its leaves shiny. You can place a dish of water near the plant or regularly spray the leaves with water.
- Pruning: If the leaves fade, cut back the dead leaves to encourage new leaf growth.
- Transplanting: Transplant your Caladium into a suitable pot size every two years to help maintain its health.
- Fertilization: obviously among these care we cannot leave aside the application of fertilizer. A topic that we will delve into in the next sections.
By following these tips, you will be able to keep your Caladium in good condition and enjoy its beauty for a long time.
2. Essential nutrients for your Caladiums
Caladium needs a variety of nutrients to thrive. Here is a list of the most important nutrients and how they act on the plant:
- Nitrogen (N): Nitrogen is essential for leaf growth and chlorophyll production. A lack of nitrogen will cause yellowing leaves and slow growth.
- Phosphorus (P): Phosphorus is necessary for the production of strong roots and flowers. A lack of phosphorous will cause slow growth and pale leaves.
- Potassium (K): Potassium is important for plant resistance to disease and stress. A lack of potassium will cause yellowing leaves and slow growth.
- Calcium (Ca): Calcium is essential for the formation of strong tissues and to prevent root rot.
- Magnesium (Mg): Magnesium is necessary for the production of chlorophyll and to maintain a healthy green coloration in the leaves. A lack of magnesium will cause yellowing leaves.
- Iron (Fe): Iron is essential for the production of chlorophyll and for maintaining a healthy green coloration in the leaves. A lack of iron will cause yellow leaves and slow growth.
It is important to note that an excess of any of these nutrients can be detrimental to the plant. Therefore, it is important to follow the manufacturer’s recommendations when applying fertilizers. With the right mix of nutrients and proper care, your Caladium will thrive and flourish.

2.1 What are NPK values?
NPK is an acronym that stands for the three essential nutrients in fertilizers: Nitrogen (N), Phosphorus (P) and Potassium (K). These three nutrients are essential for the healthy growth and development of plants.
The proportion of these nutrients in fertilizers is represented by a series of numbers, such as 10-10-10 or 20-20-20, indicating the relative amount of Nitrogen, Phosphorus, and Potassium in the fertilizer. These numbers vary between different fertilizers and should be chosen based on the specific needs of the plant.
It is important to understand the NPK values of fertilizers because each plant has different nutrient requirements at different stages of growth. For example, a plant that is flowering may require more Phosphorus and Potassium compared to a plant that is in a leaf-rapid growth stage. By choosing the right fertilizer with the right NPK ratio, you can ensure your plant is getting the nutrients it needs to thrive.
3. Best fertilizer for Caladium
In general, the fastest and easiest way to divide the different types between the commercial ones and the organic ones, many of which we can easily prepare at home. Let’s see which are the best to apply to a Caladium.
Commercial fertilizers are those that are sold in garden stores and are made in a controlled chemical process. These fertilizers often have a balanced formulation of the essential nutrients (Nitrogen, Phosphorus and Potassium) and are a good choice for those looking for a quick and convenient solution to nourish their plants.
Some of the best commercial fertilizers for Caladium include:
- Liquid fertilizers: These fertilizers are diluted in water and applied directly to the roots of the plant. They are a good option for rapid nutrient absorption.
- Powdered fertilizers: These fertilizers are applied directly to the soil and mixed into the soil before watering. They are a good option for a slow release of nutrients.
- Fertilizer tablets: These fertilizers are placed in the soil around the plant and dissolve slowly over time. They are a good option for those looking for a controlled nutrient release.
On the other hand, homemade organic fertilizers include options like compost, manure compost, fish compost, and wood ash. These fertilizers are made from organic materials and are a good option for those looking to nourish their plants in a more natural way. Unlike commercial fertilizers, however, homemade organic fertilizers can take longer to release their nutrients and do not always have a balanced formulation of essential nutrients.
In general, it’s important to follow the manufacturer’s directions for applying any fertilizer, whether commercial or organic, and to make sure you don’t overfeed, which can harm the plant.
4. When to fertilize Caladiums
The ideal time to apply fertilizers to a Caladium depends on its growth cycle and the type of fertilizer being used. In general, it is recommended to apply fertilizers during the plant’s active growing season, which is typically spring through fall.
In the spring, it is important to apply a nitrogen-rich fertilizer to stimulate leaf and stem growth. This type of fertilizer helps the plant to develop abundant and strong foliage, which is essential for its future growth and flowering.
During the summer, it is important to continue applying fertilizers to maintain plant growth. However, it is important to reduce the amount of nitrogen and increase the amount of phosphorous and potassium in the formulation. This change in the ratio of nutrients helps strengthen the roots and leaves of the plant and prepare it for flowering and seed production.
In the fall, it is important to reduce the frequency of fertilizer applications and opt for a lower nitrogen formulation to help the plant prepare for its rest period. During the winter, it is better not to apply fertilizers, since the plant is in a rest period and does not need additional stimulation.
It is important to note that applying fertilizers at inappropriate times, such as during the winter or in excess, can damage the plant and affect its growth. It can also cause a buildup of nutrients in the soil, which can be harmful to the environment. Therefore, it is important to follow the recommended guidelines to ensure that the plant receives the right nutrition at the right time.
5. How to fertilize Caladiums
The procedure to fertilize a Caladium is quite simple if a few basic steps are followed. First, it is important to choose the right type of fertilizer for the plant. If you opt for a commercial fertilizer, it is important to follow the manufacturer’s recommendations regarding the dose to apply. If an organic homemade fertilizer is preferred, compost or mature compost mixed with the soil at planting or as a top dressing during the growing season can be used.
Once the fertilizer has been selected, it is important to prepare the soil for fertilization. It is recommended to remove any weeds or debris that may interfere with the uptake of nutrients by the plant. The fertilizer is then applied evenly around the base of the plant, avoiding putting too close to the stem or leaves to prevent burns.
The frequency of fertilization will depend on several factors, such as the age of the plant, the type of soil, and the weather conditions. In general, it is recommended to fertilize once a month during the active growing season and reduce the frequency to every 2-3 months during the dormant season.
It’s important to note that over-fertilizing can be detrimental to Caladium, so it’s important to follow the recommended guidelines and monitor the plant for any signs of over-fertilization, such as yellow or misshapen leaves.
