GMO Houseplant Purifies Air – True or Scam?

The company Neoplants has been in the news a lot lately because they promoted a new genetically engineered houseplant that is claimed to clean the air in your home. In their Neo Px white paper they say, “we created a bioengineered plant system that can effectively fight air pollution”.

What is the true story?

Key Takeaways

GMO pothos houseplants have been developed that are more efficient than non-GMO plants at removing VOCs.

Does Gardening Harm the Environment?

As gardeners we think that our hobby is good for the environment but a new study finds that it is more harmful to the environment than conventional agriculture. If we follow the science, it would be better for climate change if we stop growing our own food.

GMO Myths – Understand the Truth About GMO Plants

GMOs are very controversial for two reasons. Firstly, there is a lot of misinformation out there and secondly GMOs are not well understood by the general public. Rather than discuss the topic in detail I have decided to focus on some of the common myths. I will present a number of GMO myths and if the reader is interested in more detail they can look at the references.

If you have formed an opinion on GMOs based what you have read on popular web sites and in newspapers, you have probably reached the wrong conclusion. The anti-GMO movement is strong and based almost entirely on emotion and fear. Science does not back up most of their claims.

Till vs No-Till – Which Is Better For Your Garden

I started gardening a long time ago and at that time tilling was standard practice. Most gardeners did not have a tiller so they did it by hand with a shovel. In some circles the idea of not tilling started to make waves. My first introduction was Ruth Stout’s no-till garden. Just cover everything with straw. Better for the soil and a whole lot less work. No-till became more popular in agriculture in the mid 1990 but few gardeners followed suit. Even today, many gardeners have never heard of the technique and continue the practice of spring tilling.

No-till is claimed to be better for soil and the environment since it releases less carbon dioxide into the air.

I have been promoting this idea in gardening circles for 15 years or more and slowly the idea is catching on with gardeners, but it might be time to take a step back and have a close look at the claimed benefits of no-till because science now has a lot more data on this.

When Should You Do Spring Garden Cleanup?

In years gone by it was common to clean up the garden in fall. It does result in a neat clean looking garden, but then we learned that all kinds of beneficial insects overwinter in that messy looking stuff on the ground, so we started to do cleanup in spring instead. To understand why, read this; Spring Cleanup Advice – Do it Right .

Now things have changed again. We are being told not to cleanup until temperatures are consistently above 10 C (50 F) to allow insects time to leave their winter protection. If you look at the recently circulated meme below, you have to wonder if this recommendation is valid. Does it really have to be 10 C? I see all kinds of insects when there is still snow on the ground. And what does “consistently ” mean? Is that nighttime or daytime temperature? Is it a daily high or low? How much harm will you do if it is only 9 C (48 F)? Is there any real science that supports this idea? Let’s find out.

Plants Don’t Produce Oxygen (O2) From Carbon Dioxide (CO2)

Everyone is aware of the high carbon dioxide levels in the air and its contribution to global warming. And many of you have heard that plants can convert this CO2 into oxygen. Plants are important in controlling the CO2 level, but they don’t convert CO2 into O2.

Did you know that plants also take in oxygen and produce carbon dioxide, just like animals?

All of this is a bit academic, but very interesting if you really want to understand plants.

Is Compostable Plastic Really Compostable?

Everyone wants to be green and now you see a lot of compostable plastic on the market. Is compostable plastic really compostable? Can I add it to my compost bin? How long does it take to decompose? These are all good questions that gardeners should be able to answer.

My Master Gardener group had a year end party and one member brought some compostable plastic drinking glasses. As I was collecting them at the end of the evening I started to wonder how well they decomposed. I had previously looked into compostable tea bags and was surprised by what I learned. Are these drinking glasses just some more greenwashing?

In this post I’ll discuss compostable plastic, compare that to biodegradable plastic, and explain the role of all of these in the garden.

Myths About Rainwater Harvesting Systems for Gardens

Rainwater harvesting systems are a hot topic in gardening circles. As we become more aware of the value of water, gardeners want to collect rain and use it to water their plants. Not only does this make financial sense, but in many cases the quality of the water is much better than tap water. And it is great for the environment because it sends less water to the city for processing.

Along with any good idea comes a number of myths. In this post I will look at myths pertaining to the use and harvesting of rainwater.
