Using Seasol on your plants

Using Seasol on your plants

Apr 19 , 2019

In today’s post, I’m going to chat about Seasol!

What is it?
Seasol is essentially a plant pick-me-up, helping to improve your plant’s immune system as well as its ability to absorb nutrients. It’s made from two species of seaweed, and harvested sustainably too!

Is it fertiliser?

No, it's a soil conditioner or tonic. Think of it like a multi vitamin for your green friends, helping them become stronger and more resilient, versus fertiliser which is your meat & 2 veg, the food which your plant needs to grow.



Its benefits include:

  • Stronger roots due to its growth stimulants, which is especially useful during propagation or when transplanting a plant
  • Encouraging flowering & fruiting
  • Increasing a plant’s tolerance to both heat and frost
  • Thicker cell walls thanks to its alginic acids, making plants less susceptible to sucking insects and fungus, which need to break through those cell wall before inflicting damage
  • Increased nutrient uptake, working to complement fertiliser


When & how to use it?

  • Before using it on any plant, it's recommend you spot test it to ensure that the plant responds positively to it
  • I use it when my green babies are stressed e.g. when a plant comes home for the first time, during times of extreme temps, or when a plant is unhealthy due to pests, fungus or root rot
  • For ongoing plant health, apply once every 2 to 4 weeks. For a sick plant, apply it twice, one week apart, then every 2 to 4 weeks thereafter
  • It can be applied all year round (unlike fertiliser which is used in growing seasons only)
  • It's also useful to use in tiny volumes when you're propagating plants - simply add a drop or two in the water you're propagating in, or give the sphagnum moss or soil a tiny spray with it
  • Being almost entirely phosphorus free, it can be used on any plant in your indoor or outdoor garden (but as I said above, it's prudent to test it first, just to be sure)
  • I usually spray it into the soil, and then water after (warning, it can be stinky, so I find watering it down after helps) but it can also be applied to the leaves
  • As it comes in a range of concentrate levels, please also refer to the packaging for instructions on how to mix it, or refer to the Seasol website 

If you're in Aus, it's easily found in the garden aisle of your local supermarket, at Bunnings or at any nursery.
