Fertilizing Your Garden Before or After Rain – Important Tips

Most farmers or gardeners use fertilizers to make plants grow faster and healthy. Nevertheless, determining how and when to fertilize is often an up-front task. The question is, when is the best time to fertilize your garden, before or after rain?

Given that rain is an important factor for plants’ natural growth, how should the gardeners go about fertilizing their gardens when the rain is about to fall. Over-watering and over-fertilizing are a great concern, so it is imperative to understand how to coordinate the fertilizer with the rain properly.

Fertilizing Your Garden Before Or After Rain

Why You Need to Fertilize Your Garden

Healthy and prosperous gardens require a perfect combination of correct plant elements. Apart from the right amount of water, oxygen, water, carbon dioxide and sunlight, plant roots also require an appropriate amount of nutrients. Your garden requires adequate nutrients such as phosphorus, potassium and nitrogen for healthy growth.

Why You Need to Fertilize Your Garden

Fertilizer replenishes nitrogen for optimum growth and attains the green colour of grass rather than the struggling grass brown patches. Fertilizing your garden makes the plants appear lovely and attractive. You can also control the weeds and pests by fertilizing your lawn.

Just like humans can consume vitamins and other supplements, the same thing happens to your plants. This should be the main reason why you should apply fertilizer in your garden to enable plants to get the right nutrients. Remember that too much application of fertilizers can be harmful to your garden and the environment too.

Fertilizing Before Rain

It is ineffective to apply fertilizers in your garden before heavy rains. Why so? Because rainwater leads to run-off and washes away the fertilizers before breaking down and being absorbed by the plants. So the fertilizer will be ineffective, and you will also waste money.

Fertilizing Before Rain

Consequently, heavy rains will wash away the fertilizers into the water bodies affecting their quality. This can lead to extreme long-term consequences for the surrounding community. Therefore, farmers and gardeners should be mindful of their actions and how they can impact the environment.

You can apply your fertilizer if the soil condition is mild because water is vital for plant growth and breaking down nutrients in the fertilizer for easy absorption into plant roots. But it is unhealthy to fertilize plants during drought. This is because fertilizers applied on dry roots can burn plant roots.

Fertilize After Rain

To avoid the risk of heavy rains washing away your fertilizer you wished to apply before it rains, you should use it after it rains. So wait for the grass blades to dry first. And, it is also imperative to check for a weather forecast for precipitation information. 

You should also check for steady sunlight days after using the fertilizer. You understand that sunlight is an important element of photosynthesis. So stable sunlight and suitable weather conditions as the fertilizer is used appropriately improves its effectiveness and enhances plants’ quality in your garden.

Fertilizing after also reduces the amount of fertilizer being washed away into water bodies and causing pollution. Additionally, your plants receive nitrogen from rainwater, enhancing the general health growth of your garden. Therefore, your lawn can thrive due to the effectiveness of the fertilizer you applied.

According to the environmental point of view, fertilizing your lawn at least two days after rain is the best farming solution. Although heavy rains are good for fertilizing your lawn, it is unsuitable for the environment. This is because fertilizing before heavy rains greatly contributes to water pollution.

Fertilizer washed away after heavy rain always finds their way into large water bodies such as rivers, lakes and streams. But nitrogen is the main plant ingredient from the fertilizers impacting the plant quality and being healthy. Therefore, we can confirm that applying fertilizer on your garden two days after heavy rain is the best time for you as a farmer.

It’s important to choose when soil is wet, but the lawn is dry, to prevent nutrients from washing off. Don’t apply fertilizer before the rain, and it can burn the blades. Just follow this advice and make most out of your garden and make your grass green and strong.
