Chart For Fertilizing Plants

Filed Under: Gardenality Ideas & Vision · Keywords: Fertilize, Feeding, Plants, Chart, Gardenality, Idea · 2809 Views
Hello again, I was curious if there is a chart somewhere that tells when to fertilize plants and what fertilizer to use? I am assuming that it is different for each species of plant. I know I can use milorganite as a general fertilizer but wanted to know if there is a specific plan like there is for grass.

Answer #1 ·'s Answer · 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!

Thank you Brent!! Now here is a part 2 of the charting question. I may be over thinking this but here it goes...So with the different types of plants liking different types of soil, would i need to test the soil for each plant or plant bed to determine what type of fertilizer is needed? Probably a dumb question. I have several encore azaleas and the ones on the side of my house are kinda sad looking compared to the ones in the front of the house. I realize it could be several different factors, sun, shade etc etc but could it be the soil is different. I am assuming the soil is not the same in the whole yard. I have meridian roses in my backyard and they are blooming like crazy. I have drift roses in the front and they are hardly blooming. Brooks told me to get some dynamite fertilizer for them so hopefully I can do that tomorrow. I may be overthinking all of this but I want my plants to really flourish and bloom so I want to make sure that I am doing everything as right as possible. One last thing is there a good reference book you can recommend for me to get that will help? There is really so much more to plants than I ever thought but I am thoroughly enjoying it. Thank you for your help as always,

Except for vegetable gardens and plants that require specific or extreme soil pH I usually don't bother testing the soil. The majority of plants thrive somewhere between 6 and 8 on the pH scale and most average garden soils fall in this range. That being said, if one is having trouble growing many different types of plants it's always a good idea to do a soil test to see if the pH is way off: too acidic or too alkaline for most plants.

Regarding your Azaleas it could very well be soil pH, though soil moisture and sunlight can make a difference as well. Azaleas prefer an acidic soil and different areas of a landscape can have entirely different soil pH. This is often due to the initial grading of a home site where a machine was used to maybe scrape all the topsoil off the front yard but not the back yard. One indicator that soil is too alkaline (sweet) for Azaleas and other acid-loving plants is chlorosis (yellowing of the leaves). If this occurs, you can apply soil sulfur, aluminum sulfate or chelated iron to acidify the soil. But also make sure it's not chlorophyll-sucking insects such as aphids or lacebugs that are turning leaves yellow or pale green. To check for these insects look on the undersides of leaves.

My Drift Roses don't bloom much either, but I know the reason why. Deer nibble all the buds and new growth off! So I'm gonna move all the Drift roses to the fenced-in back yard this winter. My younger brother Brian has Drift roses in his back yard that are out of this world. I think he's using the Dynamite fertilizer on them...or maybe Milorganite...I'm not or the other.

Regarding one reference book that that tells all, I don't know of one. Some of Michael Dirrs books are interesting, but not sure there's many growing tips in them. Probably the best source for information is right here on the internet. Use Gardenality and if you can't find the information here do a Google search...that's what I do sometimes when stumped on a question.

In the near future we'll be getting a new search on Gardenality that will act more like Google...picking up on synonyms and mispellings, and picking out key words in phrases. Can't wait to get that:-)

Too, always feel free to ask any questions you matter how specific...right here in Ask Experts. We don't mind answering them and then the question and answer is stored in the Ask Experts database, where others in the future who have a similar or the same question can find the answer. The best thing to do is ask each specific question in a separate Ask Experts question. That way they are filed separately and folks in the future can find specific answers to specific questions.

Always let us know if you have any questions and don't be afraid to ask for details!
