In today’s article, we will quickly debunk 20 interesting and unbelievable gardening myths and reveal some extremely useful scientific facts and tips related to Gardening.
- Fresh Cow Dung or Horse Dung is very Good for Plants?
This is absolutely false! Fresh Cow poop should never be applied for your plants, because it not only stinks but contains high levels of ammonia and salts which can burn your plants. It also contains harmful microorganisms like e-coli which are harmful to plants as well as humans. Plus, it also contains weed seeds which can produce a lot of weeds or unwanted plants in your garden. So always use decomposed cow-dung or horse dung for your plants. You can watch a detailed video on 5 hacks to quickly decompose cow dung from a link in description below or from end-screen link at the end of this video. Let’s move on..
- Is it Dangerous to Expose Roots to Light?
Well, This can be a very nice high school project for kids, to grow two similar plants, one in a transparent container and one in an opaque container and then compare these two. As you can see nothing happens to the plant grown in transparent containers. The actual concern is, root exposure to AIR and even the heat from sunlight that can cause drying and can damage your plant. But still you are advised to keep the roots in the dark. This is because of algae growth due to light and your roots are not getting enough oxygen because the algae is stealing the oxygen and nutrients for itself. So light as such does not hurt the roots, but air, heat and algae hurt the roots and kill the plant.
- Do Plants feel Pain?
There are many studies and researches conducted on this topic. Basically, Plants lack a nervous system – that is a brain and other neurological structures like nerves and pain receptors, so they should not feel pain, unlike in humans and animals where we have specialised pain receptors.
But according to some researches, “Plant can know of themselves being eaten” because studies have shown that plants release defence chemicals in response to caterpillars munching on them.
Other points include: Plants fight for territory, seek out food, evade predators and interestingly trap prey like what your see in carnivorous plants like the venus fly trap. They are as alive like any animal, and – like animals – they exhibit behaviour.
- Talking to You Plants will help them Grow?
People who really love plants and gardening will often tell you that talking to plants or even music has a beneficial impact on their overall health and growth. Despite many different scientific studies on this theory, there’s still no conclusive evidence that talking to plants helps them grow. One theory says that since plants take up carbon dioxide, and hence talking to plants releases carbon dioxide when we exhale. So, that explains it all.
- Plants can Die of Old age or aging. The oldest known tree in the world is the Great Basin bristlecone pine in the White Mountains of California which is over 5000 years old. Actually Trees grow indeterminately, meaning that with the right conditions, they can grow and grow and grow. But the only problem that limits them from reaching up to the sky is the food and water transport through xylem and phloem to the growing end from the roots. The taller the tree the more difficult it is to transport water from roots to the foliage near the top. But here what happens is instead of growing taller they increase in width and also branch out more, as you might have noticed some old trees with huge girth of their stems.
- Animal or Human Urine can be used as a Fertilizer. Yes, this is a Fact!For example, cow urine contains loads of NPK – that’s nitrogen, phosphorus and potassium which are the most essential plant nutrients for agricultural use. But it has to be applied in dilution of at least 1:20 in water.
- Is it Dangerous to go near Trees during Night Time? Well, In day time under the presence of sunlight – that’s photosynthesis, plants take up Carbon dioxide and release Oxygen. But during night they take in Oxygen and release CO2 and hence the air near trees will have lesser concentration of Oxygen and higher concentration of CO2. But, this impact will be negligible for small plants and at home gardens and only be noticeable near very large trees or in thick vegetation.
- Naphthalene balls or Moth Balls contain Naphthalene Acetic Acid and can be used as a rooting agent. It’s a Myth. NAA – Naphthalene Acetic Acid and IBA – Indole Butyric Acid are plant auxins or hormones which are entirely different compounds and used for rooting your plant cuttings. These two are entirely different from moth balls which are used to keep insects at bay.
- Watering plants on a hot sunny day will magnify the sunlight through the droplets acting as convex lenses and burn the leaves badly! No doubt, watering plants early in the morning or late in the evening is great! Because less water will evaporate during this time. But This theory that water droplets on leaves can act like mini magnifying lenses, focusing the sun’s rays and causing leaf burn has been completely disproved by physicists.
- Planting by the Moon affects plant growth and yield?
The idea that the Moon affects plant growth is an old one that is believed by many people. This is a myth! No study has proven the effect of moon on plant growth. And the only plants that use moon light for photosynthesis are certain types of phytoplanktons which are not normally found in gardens. - Crushed egg shells are a good source of Calcium to treat calcium deficiency? This is False! Even Powdered Egg shells take a long time to decompose and release that calcium into the soil and make them available for uptake by plants. You can make a water soluble calcium using egg shells by mixing it with distilled Vinegar to make this happen. You can find this detailed video from a link in description or from a link at top right corner of this screen.
- Saplings or seedlings need to be supported to protect them? True or False?
This is False! Many people recommend you to provide support to these young slender plants due to the risk of wind blowing them and things like that. Unless it’s a strong wind, tying a sapling or young plant to a support stick or any kind of support will actually do more harm than good. Research has shown that trees without support, over a period of time will develop thicker trunks, more supportive roots and more resistance to breakages.
- Do Magnets affect Plant growth?
This is a fact. Magnetism affects plant growth and seed germination positively. Studies have shown that when plants are exposed to a magnetic field with south pole facing towards the roots, Seeds germinate faster and plant grow faster and stronger in the presence of magnetic field in the soil. You can check a detailed video on this experiment from a link in description or from a link at top right corner of this video. - Can Harvested or Collected seeds be stored in a Refrigerator or Freezer?
This is not correct! Most seeds that are stored in a seed banks are first dried up so that the moisture content is reduced to about 10 percent and then these can be stored for several years. But if you freeze freshly collected seeds, the moisture content in these seeds will form ice crystals within and can destroy the seed viability. - Growing Fruit Trees in Containers is not possible due to limited space?
This is not true. You can grow them but you need little larger containers or fabric bags like more than 18 or 24 inch. You can watch a detailed episode on the top ten terrace gardening myths and facts from a link in description.
- Does Potting Mix Cause Legionnaires’ Pneumonia in Gardeners? True or False?
Do not worry! This is not True. Legionnaires’ Pneumonia is a severe form of pneumonia or lung infection mostly cause by inhaling the bacteria. Though these legionella bacteria survive in outdoor soil, it rarely causes infections. But still, prevention is better than cure. Better wear a mask while handling potting mix, specially people with weaker immune systems.

- How do I know my plant is still alive and how to save a dying plant?
There are many signs to know whether your plant can still survive. If your plant is looking dry and has shed its leaves, most of us think its dead. But actually, it may be alive or can be revived. Please watch my detailed episode on this topic demonstrating how to save a dying plant. I have linked that video in description below.
- Can we grow plants from leaves?
Yes! Some, but not all plants can be propagated from just a leaf or a section of a leaf. Leaf cuttings of most plants will not generate a new plant; they usually produce only a few roots or just decay. There are many ways you can grow leaves into a new plant, like 1. from a leaf petiole, 2. by dividing a leaf into multiple pieces for example fleshy succulent plants like sanseviera or the snake plant and other succulents. Other methods of propagation like cane or stub cuttings, root cuttings, leaf bud cuttings and so on.
- Gardening on Terrace is Bad for the Building. This is not completely true unless your building is too old with a poor construction. Otherwise if wisely planned, a garden on terrace will not be a problem, like placing the heavy containers along the walls on your terrace which are weight bearing or main walls of the building and things like that.
Water proofing the terrace is not always necessarily, unless you plan to build raised bed terrace garden. If you grow in container, you only need to check whether the water draining out of the pots is easily flowing out of the terrace and not stagnant.
- Does Electric Current affect Plant Growth? Well, there is a separate science called electro-culture farming which utilizes this effect. I have conducted a simple experiment on this topic to study the effect of electric current on plant growth. You can watch that episode from an end-screen link or from garden tips channel.
It might sound weird but, there are many incredible Uses of Charcoal in the Garden. If you want to develop a healthy garden, please watch this episode till the end.
There are many types of charcoal available to purchase. But the good news is charcoal is very inexpensive to buy, though online prices are a bit on higher side than offline purchase. You get Hardwood and Softwood charcoal. Hard wood charcoal is best for gardening. Will tell you why as we proceed further. You also get special charcoals like coconut shell charcoal, bamboo coal, horticultural charcoal, activated charcoal and so on. It doesn’t matter, you can just use hard wood charcoal for your garden.

Let us discuss the benefits of charcoal in gardening.
10. FILLING YOUR POT BOTTOM: Charcoal is porous and light weight and filling your container with pieces of charcoal at the bottom of your container, instead of using heavy weight rocks and pebbles, reduces your pot weight and you can lift or move your pot easily. This is a great boon for terrace gardeners.
9. CHARCOAL MULCHING: You don’t always need straws and twigs for mulching your top soil. You can use spread small charcoal pieces and enjoy the benefits of mulching. Mulching creates a protective covering over the soil surface and prevents moisture evaporation from the soil. It also helps to prevent weed growth over the soil.
8. GARDEN DÉCOR: Using a layer of small pieces of charcoal as mulch, especially around light-colored plants is a nice and unique way to create a different look in your garden!
7. AS AN ANTI-FUNGAL: Mixing charcoal to soil is an effective strategy to treat or prevent fungal infections in plants, especially succulents and adeniums which are more prone to fungal rot. Just include 10% of small pieces of charcoal in your potting mix to keep harmful fungi at bay.
6. INSECT KILLER: Sprinkle powdered charcoal over your plants. This helps deter many insects like the voracious beetles which can create havoc in your garden or on your crops.
5. PESTICIDE RESIDUE REMOVAL: The absorption qualities of charcoal powder, especially activated charcoal, helps in neutralizing the harmful effect of pesticides. Mix 500 grams of charcoal powder to 1 gallon of water (1 gallon is 3.78 litres). Spray or sprinkle this over the pesticide treated plants. This is very useful in edible gardening.
4. REDUCE FERTILIZER FREQUENCY: Charcoal will also absorb any fertilizer you put into the garden and will hold it over a long period of time, providing the plants a slow, steady supply. Here, you need to know one thing – Hard wood holds more nutrients than soft wood.
3. INCREASE SOIL PH: If your soil is highly acidic like PH of 5 or below, you need to increase the soil ph to desired level. A soil ph of 6.0 +/-0.5 is considered ideal for most plants. The potassium content in charcoal and also wood ash raises the pH balance of the soil and neutralizes the acid. Just don’t add too much ash, because if you increase the soil ph too much – like over 7, the plants may not do well, because most of the nutrient absorption in soil happens at a PH of around 6.0. So, How much of charcoal to add per container or per plant? You can add 100 gms or max 200 gms of charcoal per standard container – like a 12-inch container. Of course depending upon your soil PH level. You can read a detailed post on soil ph and its importance in improving flowering HERE.
2. IN POTTING SOIL: Charcoal acts as an excellent soil conditioner, thanks to its low cost, and in fact it’s a suitable replacement of lime in soil additive mixes. It makes the soil a well-draining soil which is very important for plant growth. It is the high porosity of charcoal that benefits plant soils because it offers more of the oxygen that plant roots need to stay alive.
1. REMOVES BAD ODOURS IN SOIL AND COMPOST: You can sprinkle charcoal powder over your compost to reduce foul odors that may arise during composting. Also, when included in potting soil, charcoal soaks up the nauseating odors of compost and manure, while leaving the nutritional integrity of the mixture intact.
- What is terrace gardening or rooftop gardening? In simple words it means gardening or farming or growing plants on your terrace or rooftop. If you live in a city without access to land for growing plants, a roof or terrace garden is the best option.
- Is terrace gardening bad for the building? What are the drawbacks of gardening in terrace?
Well the answer depends on two important factors. Firstly the weight of your Terrace garden, I mean total weight including containers, potting soil, plants and all the load. Secondly the Construction quality of your building whether its build very well including concrete columns, the thickness of walls and the thickness of the slab, the span of a room and so on. Generally you might have to be careful only if you building is too old or if you are just not confident on this aspect. Otherwise, if carefully planned there should not be any problem of loads arising due to terrace gardening, specially if you grow plants in containers and place them along the walls on the terrace, whatever the weight of the container might be.
- How do I start terrace gardening in a small limited space on my teres? Simplest way is to start with some plants or veggies in containers. If you want to expand, you need to plan it well, specially if the space is limited. You might want to consider the two step or three step pot stands to arrange your plants in step like fashion to save space. And its just common sense and you can apply your own ideas to save space.
- What type of plants
can I choose for terrace gardening.
You can grow any plant on your terrace garden whether ornamental plants or vegetable gardening or even fruit trees in large containers. - How can I plant fruit trees (like mango or banana trees) on a terrace garden? Yes you can grow them but you need the largest possible containers, atleast 24 inch diameter and 24 inch height by dimensions. To reduce the load on your building, consider using the fabric bags of 24 inch or 30 inch diameter.These can be purchased from amazon, I have linked that below in video description. Also choose a light weight potting mix and the placement of such heavy containers also should be done smartly like next to or on top of a column or over and along the building main walls.
- Should I waterproof
the terrace before starting a terrace garden?
Not necessarily, unless you plant to build raised bed terrace garden. If you grow in container, you only need to check whether the water draining out of the pots is easily flowing out of the terrace and not stagnant. - What type of soil
should I use for terrace gardening?
As I already discussed,to reduce the load, you need a light weight potting mix. One such formula is 40 percent cocopeat or peatmoss, 20 percent perlite or vermiculite, 20 percent garden soil, 20 percent compost. That’s 40, 20, 20, 20. - What are the practical ways to attract birds on your terrace or garden?
This is infact a vast topic. We will discuss in detail in some other episode. Simplest way is to keep some water for birds or even bird feeders Or a bird house, keeping them some seeds and so on.
- Can we install drip irrigation system on terrace garden? Infact this is one of the best options for watering on your terrace, specially if your plants are in hot sun with no green shade net. And more over, the watering hose pressure is very low on the terrace and it takes a long time to water your plants. You might require to install a pump to get that proper pressure to water your plants. Drip irrigation system is also a good option and its not that difficult to install and not that expensive. You get many options to purchase online like 100 pots, 300 pots and 500 pots options and sets. You can get one HERE.
- How do I build my terrace garden permanently with green shadehouse and how much does it cost?
Well, I have a detailed article and video on this topic titled the Making of My Shadehouse Terrace garden.
