Gardening pH levels for Landscapers and Gardeners

Posted by Sasha Kirey On 2:42 PM
We have all had that science teacher who made us learn the periodic table (and a bunch of other things we never thought would be something we would actually apply in our lives). Well, the time has come for you to finally be able to use all those numbers and elements you memorized way back when. If you are like most and forgot it all as soon as you were done with that class, you are in luck! The purpose of this article is to review a simple science lesson that you can learn and use right away, and will payoff in a pretty short amount of time.

The pH level of your garden can really help or hurt your efforts. My goal is to start you out with the basics and set you out to further improve your green thumb, as well as to give you some good ideas to inspire your garden in addition to the landscaping ideas of your own.

What is pH?



Simply put, pH is how acidity and alkalinity are measured. The pH scale ranges from 0 to 14. Zero is very acidic such as battery acid, while fourteen is the highest alkalinity such as liquid drain cleaner. We don't really need to get to into specifics as long as you know that soil being either too high or too low can seriously effect a plant’s life, color, and output.
So what do I do with it?

Well, that depends. First, start with finding the pH of the soil where you wish to plant. Remember, different parts of your yard can have pretty different pH levels, especially if one section has gotten more care while the other sat untouched. You should definitely start by finding the pH level beforehand (this rule applies just as much for potted plants). You can go to a local gardening shop or a department store and get an adequate testing system. Keep in mind - most plants grow best around neutral (6.5 to 7.0) pH level, but be sure to consult the seed package or plant guide for best results.


What do I do if the pH is too high?


If your soil pH is too high then it’s a threat to the plants you wish to grow. I recommend adding organic matter or compost. If you get manure, horse is the most ideal. Above all aim for manure without any pesticides used, as this could further harm your garden. No matter what organic matter you find be sure to rake or spread it into the soil instead of simply throwing it on top and you’ll be ahead of the game already.


What do I do if the pH level is to low?


Lime is the standard to raise pH, usually in the form of limestone. Finely ground limestone typically allows for best soil absorption. Be very careful though, the lighter your soil's composure is, the faster the pH will raise. If you mistakenly add too much lime, it could take considerable time and effort to correct. So professional consulting/assistance might be necessary.

I hope you found this article informative and helpful. I think our former science teachers would be proud. Finally, remember things grow from the ground up, so soil is a key player.
