    Great value

    As a lover of indoor plants and its effect it can have on your general well being and mental health, the plant runner food has given me the perfect solution to feeding my plants. And the company has taken it one step further with a refill bottle, making it more value for money. For anyone who cant live without their indoor plants and is looking for an easy way to feed them, look no further. This is my favourite plant website. Thank you

    I keep coming back for more

    I first bought plant runner from a fab horticulturalist pop up shop & loved it. This is my second bottle & I went large…so I don’t run out again. My plants LOVE this stuff & reward me with amazing growth, great repotting recovery & excellent propagation establishment & growth. AND it’s natural & Aussie made. WIN :)

    Best indoor plant fertiliser ever!

    Literally only after two rounds of bottom feeding my plants with this liquid fertiliser that my plants were noticeably upright, greener and overall healthier. Am looking forward to seeing how they grow over the next month or so otherwise will definitely purchase again!
