A - Indoor plants do typically need fertiliser to thrive because the nutrients in their potting soil can become depleted over time. However, the frequency and type of fertiliser you should use depend on various factors, including the type of plant, the potting mix, and the time of year.
Here are some guidelines for fertilising indoor plants:
Type of Fertiliser
There are two primary types of fertilisers: liquid (water-soluble) and granular (slow-release). Both can be used for indoor plants, but the choice depends on your preference and the specific needs of your plants.
Liquid Fertiliser
Liquid fertilisers are mixed with water and applied directly to the soil during watering. They provide a quick nutrient boost and are typically used more frequently (usually every 4 weeks during the growing season).
Granular Fertiliser
Granular or slow-release fertilisers are applied to the soil's surface and release nutrients gradually over time. They require less frequent application, typically every 2-3 months.
Plant Type
Different types of indoor plants have varying nutrient requirements. For example, flowering and fruiting plants often benefit from higher levels of phosphorus (P), while foliage plants may need more nitrogen (N). Research the specific needs of your plants to choose the right fertiliser formula.
Growing Season
Most indoor plants go through a period of active growth during the spring and summer. This is when they have the highest nutrient requirements and when you should fertilise more regularly. During the fall and winter, when many plants are dormant or growing more slowly, reduce or suspend fertilisation.
Soil Type
If you use a high-quality indoor potting mix enriched with nutrients, your plants may require less frequent fertilisation. However, over time, even the best potting mixes can become depleted, so it's essential to monitor your plants' health and adjust your fertilisation schedule accordingly.
Dilution and Application
When using liquid fertiliser, follow the instructions on the product label for dilution and application rates. It's better to under-fertilise than over-fertilize, as excess fertiliser can harm your plants.
Observation
Pay attention to your plants' health and growth. Signs of nutrient deficiency may include yellowing leaves, stunted growth, or reduced flowering. Adjust your fertilisation routine if you notice these symptoms.
Flush with Water
Occasionally, it's a good idea to flush the soil with plain water to remove any excess salts that can build up from fertilisers. This can help prevent nutrient imbalances and potential damage to the roots.
Remember that every plant is unique, so it's crucial to research and understand the specific fertiliser requirements of each indoor plant you have. Over-fertilising can lead to nutrient imbalances and harm your plants, so it's generally safer to use less fertiliser and increase it gradually if necessary. Proper fertilisation, combined with appropriate watering and light, will help your indoor plants thrive.
