One of the hottest new additives for plants is silicon, which is also incorrectly called silica. It is claimed to reduce pests, improve growth and fend off diseases such as powdery mildew. Although there is some truth to the claims, there is also a lot of misinformation in the gardening community.

Best Fertilizer for Indoor Plants and Containers
There are so many types of fertilizer it’s hard to know which one to use. Which NPK ratio is best? Is one brand better than another? Organic vs synthetic. Soluble vs slow release. This all seems so complicated, but in this post I will simplify the whole process of selecting the best fertilizer.
Key Takeaways
- The best NPK ratio for most plants is 3-1-2, some like 3-1-3.
- There is no such thing as plant specific fertilizer.
- Mix fertilizer so nitrogen is at about the 100 ppm level.
- Fertilize with every watering, use just water once a month to flush the pot.
Using Conductivity (EC) and pH Measurements to Control Hydroponic Solutions
Hydroponics can be a great way to grow plants but it is important to make sure the nutrient solution contains enough food for the whole growth cycle. If either pH or EC (electrical conductivity) is out of whack, plants grow poorly or stop growing all together. It is therefore important to measure and control the nutrient solution. This post will look at what the numbers mean and what you should do about them to keep plants growing well.
Key Takeaways
- Keeping the pH and EC in the preferred range is important for plant growth.
- Use EC and not TDS for measurements and online discussions.
- Nutrient lockout does not really exist, but is important to understand.

Molasses for Plants
This is a hot gardening topic these days and many of organic gardeners are promoting the idea that you should add molasses to your compost pile, to compost rea or even spray plants with it. In tea and on soil it makes microbes grow and on plants it can prevent pests.
Molasses; should you eat it, or use it in the garden?
How To Lower High Phosphorus Levels in Soil
Over fertilization with either synthetic and organic material can result in toxic soil that no longer supports plant growth. This is a common problem in raised beds that are filled with too much organic matter but it can occur in any garden. Today I’ll have a look at both the cause of high phosphorus in soil and ways that you can use to reduce the level.
Key Takeaways
- High phosphorus levels are a series problem that is becoming more common.
- Reduce the use of synthetic and organic fertilizer with high relative phosphorus.
- Reduce P levels by growing the right crops and removing all organic matter.
Is Copper Sulfate in Miracle-Gro Fertilizer Toxic?
Some types of Miracle-Gro fertilizer are a blue color due to the addition of copper sulfate. But copper sulfate is toxic to microbes and fungi. Several online sites and videos are now claiming that it makes the fertilizer toxic and should never be used because it kills soil microbes. Are they right?
How To Fertilize Tomato Plants
Discussions about fertilizing tomatoes is mostly about selecting the right NPK and rarely discusses the amount to use. When quantity does come up, most comments suggest following the instructions on the box. But are the instructions on the box correct? Are the instructions complete enough so that you can apply the correct amount?
This post will compare some commercial products to see what they suggest and then I’ll compare that to reliable agricultural recommendations to see how much fertilizer gardeners should be using to grow great tomatoes.
Is Yeast a Super Fertilizer for Plants?
The hottest new trend is to fertilize plants with a magical “superfood” fertilizer made from yeast. Is this a good idea? Is it a good fertilizer? Does it grow better plants? Let’s look at the facts.
What is Hydroponic Fertilizer?
Hydroponics has become more popular especially with the invention of the aerogarden systems, like AeroGarden. DIY home hydroponic grow systems are also popular, as are Kratky methods. All of these systems require hydroponic fertilizer which is quite a bit more expensive than regular soluble fertilizer. It begs the question, can you use regular fertilizer in place of hydroponic fertilizer? What makes hydroponic fertilizer special and what should you be looking for when you buy them?

Lawns Reduce CO2 Levels
Is the lawn good or bad for the environment? You can look at this problem from different points of view and today I would like to examine the specific question; do lawns reduce CO2 levels.
A study done by Scotts Miracle Gro concluded that “The lawn is a good and valued resource for sequestering carbon, even under various typical lawn management practices”. Is this really true??? The answer is more complicated than you might think.
What is Salt – It May Not be What You Think
Some people won’t use synthetic fertilizer because it contains “salts”. For years I was told not to use mushroom compost because it contains “too many salts”. Salt is also recommended to kill weeds and just today I saw a post which suggested pink Himalayan salt makes plants grow better. You can buy commercial sea salt to fertilize your plants. This doesn’t make sense. Salt is a weed killer and it’s a good fertilizer?
As a gardener it is crucial that you understand which salt is being discussed so you don’t use the wrong one and harm your plants. This blog will help you through the maze of salt crystals.
Is Milk a Good Fertilizer
There has been a lot of chatter on the net recently about the magical benefits of milk as fertilizer in the garden. Most of the Magic is Imagined.
