Seaweed Liquid Fertilizer is a natural plant growth booster made from seaweed extract. Also known as liquid kelp, liquid kelp fertilizer, or seaweed extract for plants, it supports healthier roots, leafy growth, nutrient uptake, and plant recovery during active growing stages.

It can be used as both a root feed and foliar spray, making it useful for rooftop pots, balcony plants, kitchen gardens, vegetables, herbs, flowers, fruit plants, indoor plants, and lawns. In Pakistan’s hot weather, it is especially helpful for plants recovering from heat stress, transplant shock, weak growth, or irregular watering.

Unlike regular NPK fertilizers, seaweed liquid works more like a plant biostimulant . It contains natural bioactive compounds and trace nutrients that help plants use available nutrition more efficiently, especially when used with compost, vermicompost, or balanced fertilizer.
