The use of wood chips for mulch is very popular but there are also many myths about it. Will it rob nitrogen from the soil? Is the dye on black mulch toxic? Do wood chips attract termites and can it ignite spontaneously?
These are just some of the myths I’ll investigate in this post.
Cornus mas is a shrub or small tree that blooms very early in year, even before forsythia. It has attractive yellow flowers followed by red fruit that develops in fall. It does not make a big splash in the garden, but adds a nice touch to a shrub border.
It’s planting time and most fertilizer manufacturers and nurseries are pushing their high phosphorus products, usually under names like Plant Starter, Root Booster and the one I really like “MegaMass”. These fertilizers claim to “supply the high phosphorus needed for rapid root development”.
Who doesn’t want good roots on their newly planted babies? Are roots not the key to great plants?
Let’s have a look at this extremely common myth.
Flueggea suffruiticosa is a rare shrub in gardens that is interesting, but not spectacular, until fall when it turns a beautiful golden color. It is quite architectural, presenting a weeping habit.
Despite its name, Bokashi composting is a fermentation process for handling kitchen scraps right in the home. It is fairly easy to do and produces few odors. The majority of the material ends up as fermented kitchen scraps and some is drained out the bottom as a brown liquid, commonly called Bokashi tea or Bokashi leachate. Advocates of this process claim that the Bokashi tea is a good fertilizer, full of all the nutrients your plants need.
In my previous discussion about Bokashi, I speculated that the tea contained few nutrients. At the time I found no chemical analysis of Bokashi tea, not even from proponents of the process. One of my readers has now found such a study and I will have a close look at the data in this post.
There is a lot of information floating around about fertilizing orchids, but much of it is wrong. For example, the whole concept of “orchid fertilizer” is a myth because there is no such thing.
It’s time that orchid growers understand fertilizers better. It will benefit your plants and save you money.
Hamamelis x intermedia ‘Arnold Promise‘ is one of the most popular witch hazel cultivars, but that still makes it an uncommon plant to see in the garden. It is a small vase-shaped tree that can be kept quite small with pruning, so it will fit into any garden. It can even be grown as a small potted plant or bonsai.
There have been several articles in the past few years that recommend planting trees in square holes rather than round holes. It is claimed that the square holes will result in more root growth into your native soil outside of the planting hole, which is good for proper tree development.
Does this work? Should we all start making square holes to plant trees?
Check out social media gardening groups and you will find at least one post each day asking for ways to control fungus gnats. They are perceived to be a huge problem with seedlings and other indoor plants. Much of the online advice doesn’t work, so let’s swat some myths about fungus gnats.

Everybody wants to grow nutrient dense food that is more nutritious, but what methods produce the best food? There is lots of talk online about organic gardening producing healthier food but is that really true? Are heirloom varieties better for you than hybrids?
In this post I’ll look at some interesting studies that try to answer these questions and the answers will surprise you.
Abelia mosanensis is a lovely shrub that few people grow. I am not sure why because it is very easy to grow, flowers well every year and is more fragrant than just about any other shrub in my collection. It does sucker a bit, but is easily controlled. It also forms nice red-orange fall colors.
Cactus are very weird plants. They almost never have leaves. They sit there and do nothing for a good part of the year. They don’t flower – or do they? If you are old enough to remember all of the cowboy movies on TV, you are sure to know that you can always stop by a cactus and get a drink.
My first foray into horticulture was a collection of over 100 different cactus, under lights in my bedroom. At that time I went to Europe, in part to see “native cacti”. I’ve grafted them, and even grown them from seed. Fast forward 40 years, and I still have a cactus growing in the garden (zone 5).
For this post I have collected together all of the cactus myths that I could find. Enjoy.
