Timing the Application of Natural Fertilizers Before a Rain to Encourage Deep Roots

If you're looking to improve the health and growth of your plants, fertilizing can be a great way to provide them with the nutrients they need. But when it comes to natural fertilizers, timing is everything. Applying natural fertilizers before a rain can be an effective way to encourage deep roots and promote healthy growth. Here's what you need to know.

Why Fertilize Before a Rain?

Fertilizing before a rain can be beneficial for a few reasons. First, it allows the fertilizer to be watered in immediately after application, which helps to ensure that the nutrients are absorbed by the plants' roots. When it rains, the water carries the nutrients from the fertilizer deeper into the soil, which can help to promote healthy growth.

Additionally, fertilizing before a rain can encourage deeper root growth. When plants receive nutrients at a deeper level, they are forced to extend their roots deeper into the soil in order to access them. This can lead to stronger, healthier plants that are more resistant to drought and other stresses.

Choosing the Right Fertilizer

When it comes to natural fertilizers, there are a few options to choose from. Here are a few popular choices and their benefits:

  • Compost: Compost is a great all-purpose fertilizer that provides a wide range of nutrients to plants. It also helps to improve soil structure and water retention, which can further encourage deep root growth.

  • Manure: Manure is another popular natural fertilizer that provides a good balance of nutrients to plants. It's especially high in nitrogen, which can be beneficial for leafy greens and other fast-growing plants.

  • Fish emulsion: Fish emulsion is a liquid fertilizer made from fish byproducts. It's high in nitrogen and other nutrients, making it a good choice for plants that need a quick boost.

Applying the Fertilizer

Once you've chosen your fertilizer, it's time to apply it. Here are a few tips to keep in mind:

  • Check the forecast: Make sure that rain is actually expected, and that it will be enough to water in the fertilizer. If it's just a light drizzle, the fertilizer may not be watered in enough to be effective.

  • Use the right amount of fertilizer: Applying too much fertilizer can be harmful to plants, and can also lead to nutrient runoff if there is heavy rain. Be sure to follow the instructions on the fertilizer package and apply the appropriate amount.

  • Water the fertilizer in: If rain isn't expected for a few days, it's a good idea to water the fertilizer in yourself. This will help to ensure that it's absorbed by the plants' roots and encourages deep root growth.


Fertilizing before a rain can be an effective way to encourage deep root growth and promote healthy plant growth. By choosing the right natural fertilizer and applying it at the right time, you can give your plants the nutrients they need to thrive. Just be sure to check the forecast, use the right amount of fertilizer, and water it in if rain isn't expected for a few days. With a little care and attention, you can help your plants grow strong and healthy.

At Rusty Top Farms, we're dedicated to supporting our veterans and helping them experience the healing power of gardening. We're currently raising funds to build garden crates for veterans who may not have access to a garden or who may need extra support to get started.

Each garden crate costs us $300 to build, and we rely on donations from our community to make this project possible. If you'd like to support our mission and help us build garden crates for veterans, please consider making a donation through our fiscal sponsor at . Every donation counts and makes a difference in the lives of our veterans.

Thank you for your support and let's continue to work together to support our veterans and build a more resilient community!
