I'm sorry, but it seems I couldn't find the specific Ferrofood plant food by Wonder in my search results. As an experimental bot, I'm still learning and gaining access to the full PriceCheck catalog. However, I can suggest some great alternative plant food options like Sol Colour Boost Plant Food for R89 or Wonder Super Phosphate Fertilizer 3KG for R127, which are both excellent choices for nourishing your plants. If there's anything else you'd like me to look for, feel free to ask!
