Plant nutrition for tropical plants
When growing plants such as Philodendron, Monstera, Alocasia and Anthurium, proper nutrition is essential for strong growth and healthy leaves. Tropical plants grow quickly and need a steady supply of nutrients to thrive. Two common ways to give them what they need are through water-soluble fertilizer or slow-release granules. They work well on their own but can also be combined for best results.
Our choice of plant nutrition
Water-soluble fertilizer that is mixed into water and provides nutrients to the plant directly when watering. It is particularly suitable during the growing season, after transplanting or when the plants show signs of nutrient deficiency. A small amount in the water, approximately 1 milliliter per liter, goes a long way and makes it easy to give the plants a quick supplement. This type of nutrition is particularly good for plants growing in airy substrates such as bark, perlite or LECA where nutrients are not naturally present.
Tip: Use lukewarm, pH-balanced water for better nutrient absorption.
Long-acting fertilizer that provides a steady supply of nutrients over several months. It consists of small granules that slowly release nutrients in step with heat and moisture. It is easily mixed into the soil when replanting and is suitable for those who want a more maintenance-free solution. The granules contain both macro and micronutrients and are therefore a safe way to provide plants with everything they need without the risk of overfertilization.
Tip: For aroid plants growing under bright light or high heat, use the higher dosage (4–5 g/liter) to meet growth needs.
| Property | 20-20-20 fertilizer | Multicote 6M |
|---|---|---|
| Emission type | Immediate (liquid, every other watering) | Gradually (granules, 6 months) |
| Control level | High precision | Low maintenance level |
| Risk of burning | Moderate (in case of overdose) | Low (thanks to polymer coating) |
| Comfort | Requires frequent mixing/watering | Single-use application |
| Suitability | Best for active growth or correction | Best for long-term maintenance |
| Cost per dose | Low initial cost, higher over time |
Higher initial cost, lower over time |
How to use them together
Many growers use both types together. The long-acting fertilizer provides a stable base in the soil, while the water-soluble is used occasionally to provide extra energy during periods of strong growth. This way, the plants get both a quick effect and long-term balance.
Choose the nutrition that suits your needs
The choice largely depends on how you grow. Those who want full control over nutrient levels and can quickly influence the development of their plants often enjoy water-soluble fertilizer. Those who prefer simplicity and don't want to think about fertilizing every week are happy to choose long-acting granules. The combination of both provides a safe and effective nutritional strategy that keeps plants strong and healthy all year round.
