Drought Resistance: Just-Kelp helps plants grow with less water
Small trials have shown that the seaweed extract Just-Kelp has a significant effect on drought resistance in garden cress (Lepidium sativum). Seed trays were planted with cress and sprayed with 2.5% and 5% Just-Kelp solution after planting. A ‘control’ tray of cress did not receive any Just-Kelp extract, only water. Trays were watered normally between treatments. Once the cress was fully grown, watering was stopped for 10 days, and then resumed. It was very clear that cress plants treated with Just-Kelp before the ‘dry spell’ continued to look strong and lush even when not watered, while the ‘control’ plants wilted and did not recover well. Yields of cress were up to 87% greater when treated with Just-Kelp seaweed extract, and the roots were noticeably thicker and more developed. This trial shows that Just-Kelp stimulates biological processes that improve a plant’s resilience to drought, which may be due to its content of bioactive compounds such as amino acids, complex carbohydrates, various macro and micro nutrients as well as plant growth hormones. Based on the success of this trial we will carry out further research on the drought resistance properties of our Just-Kelp extract. Interested in trying some on your plants? BUY NOW>

Increased Flowering
Pansy plants sprayed with a 5% solution of Just-Kelp seaweed extract 1-2 times per month produced up to 39% more flowers per plant after 6 weeks, compared to those that were not treated with Just-Kelp liquid seaweed extract. Want to have more flowers? BUY NOW>
Improved germination
Seaweed contains natural phytohormones which are known to ‘wake’ seeds up from dormancy. To test this, we soaked radish seeds in a 5% solution of Just-Kelp for 24 hours before planting, and soaked ‘control’ seeds in water. There was a germination rate of 73% for the ‘control’ seeds, and a germination rate of 93% for the seeds soaked in the dilute Just-Kelp solution. This demonstrates that Just-Kelp liquid seaweed extract increases germination rates of seeds by up to 20%. Interested in how seaweed works as a growth stimulant? READ MORE>.
