Key words of the passage: seaweed; use; liquid fertiilzer; apply

The powder form of seaweed fertilizer can be sprinkled on top of soil, mixed into potting soil or diluted to create a nutrient-rich tea. Typically, these powder fertilizers are often sold as natural kelp meal or kelp fertilizer and can be found online or at local gardening stores. They are easy to store and have a longer shelf life than liquid fertilizers.

Liquid fertilizers are likely to be more expensive than the powder counterpart but can be used throughout the growing season. These are typically concentrated liquid kelp and will need to be diluted before use. Follow the recommended dilution ratio on the back of the product packaging; it will likely call for only a few tablespoons of fertilizer per one gallon of water.   Diluted liquid seaweed fertilizer can be used to drench the roots of transplants. Leave the seedlings or plants in their original pots and place the pots in a larger container with the seaweed solution. Let the plants soak up the fertilizer for 1-2 hours or even overnight. This action is akin to bottom watering plants and is one of the best ways to deliver nutrients directly to the roots.

Liquid fertilizers can also be watered into the soil or sprayed on to leaves. Make sure not to apply before rain. Plants will take up some of the nutrients of the fertilizer through their leaves. Liquid fertilizer can be used on a variety of vegetables, flowers, fruit trees and even potted plants. Carefully follow the manufacturer’s instructions. If you are using the fertilizer during the growing season, do a test application before applying widely throughout the garden.
