· Hi Jennifer - This is a good question. You're right about various types of plants having different fertilization needs. Climate, location, and soil conditions are also factors that have to be considered. That being said, plants in the same genus, such as Ilex (Hollies) often share similar needs. As with Rhododendron, Camellia, Gardenia, and Juniper, most Holly require an acidic soil so like to be fed with an acid-forming fertilizer that contains iron or sulfur. A natural fertilizer such as Milorganite contains 4% naturally occurring iron so is great for use on these types of plants. Though these plants like the same type of plant food, the timing for feeding them varies. For example, you don't want to fertilize spring flowering shrubs such as azaleas until after they've flowered, and flowering might end for azalaeas at different times depending on the cultivar (variety) or the region where they are growing.
So you can see that making an accurate chart that would serve everyone in different locations would be difficult to create without there being some flaws in the system. This being said, many of the plant files in Gardenality have some general planting instructions on them and you might find articles in Gardenality pertaining to the fertilization methods for various types of plants.
Perhaps the best thing to do is make a chart that lists all of the plants in your landscape and then note their feeding times and the type of fertilizer they prefer.
Maybe if Team Gardenality puts its heads together we can come up with a way that our members can make their own plant feeding charts right here on Gardenality. And, once the chart is filled out, we could even have it where timely notifications are sent to our email or mobile devices to alert us generally when certain types of plants we have in our personal plant lists need to be fed. We could also do this for pruning.
So you brought a great idea to Gardenality! I will definitely put this on our To-Do list. This will be a fun project for us to brainstorm and if we can pull it off an invaluable tool for all of us.
Lots of things are happening behind the scenes right now with Gardenality. We have many exciting new features coming and this will be another great one. Thanks for the great idea and we'll keep you updated with our progress. Continue to keep the great ideas coming. We're all ears!
