Pepper seedlings are delicate, and over-fertilizing them at an early stage can lead to problems such as nutrient burn or leggy growth. It's important to wait until the seedlings have developed at least two sets of true leaves before applying any fertilizer. Before this stage, the seedling relies on the nutrients stored in the seed itself.
Once the seedlings are ready for fertilization, start with a diluted solution of a balanced fertilizer like BigAss Peppers Fertilizer. Using a weaker concentration at this stage ensures that the seedlings receive the nutrients they need without overwhelming them. A liquid or water-soluble fertilizer is ideal for seedlings, as it can be applied directly to the soil without the risk of over-application.
As the seedlings grow and develop stronger roots and stems, you can gradually increase the strength and frequency of fertilization. This ensures that by the time they are ready to be transplanted, the seedlings are strong, healthy, and capable of thriving in your garden.
