How to Use a Seaweed Fertilizer Through Foliar Feed
Seaweed fertilizer has many benefits. These types of fertilizers provide natural hormones and many nutrients not found in other forms of fertilizer. Since most plants absorb their nutrients through the leaves, applying this with a foliar method will benefit the plant even more. Foliar simply means placing the fertilizer on the leaf itself. As the plant absorbs the sunlight it needs, it will also be absorbing the nutrients found in the fertilizer. Here's how you can do this.
Step 1- Examine the Plants
It's advisable to check over the plants you plan on fertilizing and remove any dead leaves or leaves that look like they may have been infected. These will just get in the way or cause damage to the plant.
Step 2- Mix The Fertilizer
When you purchase your liquid seaweed fertilizer, you will want to check to see if it's concentrated. Even formulas that are not concentrated can cause the leaves of many plants to burn. If the plant is not used to the extra nutrients, it may not be a great idea to start off with a full strength solution. In most cases you will need to dilute the mix by 50%. If the instructions on the bottle tell you to dilute more, then follow those.
Step 3- Apply Spray
Some forms of seaweed fertilizer will work by attaching directly to your garden hose, others will utilize a spray bottle. Either way, you will want to lightly mist the plants with the seaweed fertilizer. Try to ensure that you can reach the underside of the leaves if possible. This is where the leaves will absorb most of the nutrients, especially in weather that is less than 80 degrees.
Step 4- Check Back in 2 Days
After you are done with the initial fertilizing, check the plants in about 2 days. If you see any signs of plant burn then you will want to dilute the fertilizer more next time around. Depending on the type of plant and the strength of the fertilizer, you may be able to feed as often as every week, or as little as once a month.
You can also find seaweed fertilizers in grain form. This type of fertilizer is applied to the plant base and is absorbed through the soil. It's not as fast acting, and doesn't require frequent feedings. Both forms of seaweed fertilizer have benefits. Taking care of the root system will go a long way in the health of the plant. You should avoid using a foliar method and a soil method at the same time though.
