Richgro has unveiled a new secret weapon for gardeners this spring – Black Marvel Liquid Plant Food.
With its unique combination of fast-acting iron, high nitrogen levels and a potash boost this is a liquid formulation your plants with love. And, just like the popular Black Marvel granular style, which has been in the market for over a decade, there is one specifically designed for roses and other flowering plants and another with a balance well-suited to heavy-feeders such as citrus and other fruit trees.
