It's generally
better to apply fertilizer before rain, here's why:
* Nutrient Loss: Rain can wash away fertilizer, especially granular types, before it has a chance to be absorbed by the soil and plants.
* Improved Absorption: When fertilizer is applied before rain, the water helps dissolve the nutrients and move them deeper into the soil where plant roots can access them.
* Soil Compaction: Applying fertilizer after heavy rain can lead to soil compaction, making it harder for roots to grow and for water to penetrate.
However, there are some exceptions:
* Heavy Rains: If a heavy downpour is expected immediately after fertilizer application, it might be better to wait. This is especially true for granular fertilizers that are more susceptible to being washed away.
* Specific Fertilizer Types: Some fertilizers, like slow-release granules, are designed to withstand rain and can be applied even after rain.
* Soil Type: If you have sandy soil that drains quickly, applying fertilizer before rain can be more beneficial. If you have clay soil that drains slowly, applying fertilizer after a light rain can help prevent runoff.
Here's a general rule of thumb:
* Apply fertilizer before a light rain or drizzle. This will help the nutrients sink into the soil without being washed away.
* Wait for soil to dry slightly after a heavy rain before applying fertilizer. This will reduce the risk of runoff and compaction.
Ultimately, the best time to apply fertilizer depends on your specific situation, including your soil type, the type of fertilizer, and the weather forecast.
