You do realize that corporations have entire departments whose sole responsibility is to sell you on their product, right? Right? You do realize that you are being suckered when you buy certain things, right?
I recently went to Lowe's to pick up some potting soil. (Yes, I realize dirt is right outside my door and I have a lovely big pile of compost, but unfortunately...it is frozen. So it goes....) I also needed some plant food for my amaryllis. The poor thing refuses to send up a flower stalk, so I needed to feed it a bit. (yes...I prefer using compost, but again, unfortunately...it is frozen).
So I went to pick up a bag of fertilizer and noticed that bags of holly fertilizer were on sale for 75% off. Now friends, there is no such thing as holly-only fertilizer. It is basically fertilizer formulated for acid loving plants that is packaged as holly fertilizer around Christmas time. You can use this fertilizer on any acid loving plant. In fact, as long as it is not acid hating, you can use this in small amounts on just about anything. You don't believe me? Just check out the back of the package where is lists all of the plants that you can use this fertilizer on.
It's perfect. ...and it is only $2.49 for a giant bag. I bought them out.
By the way, if you buy them out and you won't USE all of the fertilizer in a fairly short amount of time, it will lose its potency and you've just been suckered again...by a clearance tag.
Moral of the story?
Don't be a sucker for marketing and packaging.
Do a little research...just a little...like reading the package.
