Yellow Geranium Leaves
My large geranium plant I have in the house has yellow edges on its leaves. I was told the soil might need nitrogen. Can I use blood meal?

There are many reasons for a plant to develop leaf yellowing, nitrogen deficiency being only one. It could also be a watering issue, perhaps too little. I would first check the possibilities in the following article before applying any nitrogen fertilizer. That said, blood meal should be used with caution, as it contains a high amount of nitrogen and you risk giving your plant too much. I would recommend a slow release fertilizer, like Osmocote, for your houseplant.
