Dr Horticulture is IOS app that uses image processing to solve the issue of over fertilization of plants. The app does this by taking a user uploaded image and processing it to get an index value that represents the green of the plant's leaves. With that index and the Research developed by Dr. Khoddamzadeh it is able to accurately give feedback as to how much fertilizer the plant need, if any at all. The domain of the app is in potted flowering plants at the moment. However more plants will be introduced in the future. With the end goal being to stop fertilizer runoff and stop the contamination of water due to Algol blooms caused by the fertilizer.
