What are the Benefits of Seaweed Fertilizers?

In the era of all things organic and sustainable, plus the perpetual rule of houseplant love and agriculture, seaweed concentrated fertilizers seem to be the holy grail of plant fertilizing. This is not a new invention, however the benefits of seaweed in agriculture have been known for centuries. Of course, this type of fertilizer is used not only in agriculture, but also in houseplant care and lawn maintenance. Did you know, for example, that seaweed concentrated fertilizers are used on professional golf courses and sports fields, too?

Seaweed concentrated fertilizers contain many useful nutrients, more than 60 minerals, vitamins and natural growth hormones. This fertilizer can not only be used on most plants, but it can be used at different times of the plantslife cycle, from seed to produce. Soaking the seeds in the solution, for example, would initiate faster germination, better root development and higher survival rate. This type of fertilizer will make the roots stronger and the plant more resilient. If you apply the solution on the leaves, the nutrient absorption will be increased, and the fertilizer itself will be more efficient. During potting and repotting it can be used as a rooting solution and a soil conditioner, and will help against transplant shock, too. Seaweed concentrated fertilizers will also promote sprouting, producing more flowers, fruits and vegetables, and will extend the shelf life of the produce.

However, in order to achieve the desired results, one must adjust the concentration based on specific needs – if you’re using Plant Vitamins, you can find all the useful information and instructions HERE.
