Okay, so, I’ve been messing around with my plants lately, trying to get them to grow better, you know? And I stumbled upon this stuff called 20-20-20 water-soluble fertilizer. I was like, “What the heck is this?” So, I did some digging, and it turns out it’s a pretty common fertilizer that’s got equal parts nitrogen, phosphorus, and potassium. Sounds important, right?
So, first, I grabbed a bag of this 20-20-20 stuff. I noticed it says you can use it in both spring and fall. Cool, I thought, that’s pretty versatile. Then I needed to figure out how to use it.

I read on the bag that you gotta dissolve it in water. For spraying it on the leaves, it said to mix 1 to 2 grams of the fertilizer with a liter of water. I got my measuring spoons and a big jug and mixed it all up. It dissolved pretty easily, which was nice. Then, I poured the mixture into my spray bottle and sprayed it all over the leaves of my plants.
- Grabbed a bag of 20-20-20 fertilizer
- Read the instructions on the bag
- Mixed 1-2 grams of fertilizer with 1 liter of water for foliar spray
- Poured the mixture into a spray bottle
- Sprayed the plants’ leaves
But you can also put it in the soil. For that, the bag said to use 3 to 5 grams per liter of water. So, I did another batch, this time a bit stronger, and watered my plants with it, making sure to get it around the roots where they can soak it up. The bag also mentioned that this fertilizer has other nutrients and doesn’t have sodium, chlorine, or heavy metals. That made me feel better about using it.
- Mixed 3-5 grams of fertilizer with 1 liter of water for soil application
- Watered the plants, focusing on the root zone
The instructions said to do this every 10 to 15 days when the plants are really growing. So, I made a note on my calendar to remind myself. This fertilizer is supposed to work with any watering system. That’s handy, I thought.
Now, I did hear that this 20-20-20 stuff might not be the best for tomatoes. Something about them needing less nitrogen and more potassium. I don’t grow tomatoes, so I didn’t worry about that too much, but it’s something to keep in mind if you do.
Keeping Track
I started using this fertilizer a few weeks ago. I’ve been watering and spraying my plants like the bag said. I’ve been keeping an eye on them, and I gotta say, they do seem to be doing better. They look greener, and they’re definitely growing faster. I’ll keep using this stuff and see how it goes. Maybe I’ll even try it on some other plants around the house. Who knows, maybe I’ll finally have that green thumb I’ve always wanted!
