Warning: Ready-to-use Products Are Often Expensive

A bit of economic advice today. 

When you need to buy a fertilizer or pesticide (hopefully an organic one!), always buy the concentrate rather than the ready-to-use product (hint: the latter is often sold in a spray bottle). 

That’s because the ready-to-use product is composed almost entirely of water with just a hint of the base product (typically 50 parts water to one part of concentrate). As long as you have running water at home, you can easily dilute the concentrate yourself … and imagine the savings! 

Since the concentrate is 50 times more condensed than the ready-to-use product, if both are approximately the same price (and they often are), the concentrate actually costs 50 times less!

  1. Are these concentrates readily available?…I haven’t seen them.

  2. Ease of use over practicality and economy. The quick and easy usually win out. Caveat emptor!
