Cinnamon in the garden: a useful plant protection?

Cinnamon is very popular as a spice in the kitchen. But can ground cinnamon also be used as a pesticide or against ants in the garden?

Cinnamon is often only known to us as ground cinnamon for seasoning in the kitchen. The spice is made from the peeled and dried bark of the cinnamon tree (Cinnamomum) won. In some cases, the wafer-thin bark is peeled off the tree or the thin pieces of bark fall from the tree themselves. For the drying process, several pieces of bark are placed on top of each other and roll up to form the familiar cinnamon sticks. These can finally also be ground to cinnamon powder - the starting product for alternative plant protection and pest control measures of an ecological nature. How cinnamon is supposed to help against plant pests and ants, we will take a closer look below.


Cinnamon can not only spread a Christmas scent: it can also be useful as a pesticide, a deterrent against annoying insects or for rooting cuttings.

Cinnamon against mold and Co.

Even scientific studies confirm that the treatment with cinnamon has an effect against fungal pathogens. Thus, under laboratory conditions, a development-inhibiting effect of the components of the cinnamon powder against the development of gray mold (Botrytis cinera) and various species of the genus Phytophthora detected. It can relieve the pressure of the fungal infestation if the plants are sprayed or even watered with a solution consisting of cinnamon powder and water as a precaution, or even if the infestation has already occurred.

How to use the cinnamon solution correctly for use in the garden:

  • One level teaspoon of ground cinnamon ...
  • dissolve in 5 liters of warm water ...
  • let it go for a few hours ...
  • and the cinnamon solution is ready for use as a pesticide.

Due to the development-inhibiting effect on fungal pathogens, cinnamon is also suitable for use on specially grown seedlings immediately after germination. Here, the ground spice can help against the dreaded fall sickness of the seedlings and thus ensure an improved rate of reproduction. Here you don't necessarily have to make a brew and spray the cinnamon as a solution, but can also sprinkle the ground cinnamon over the seedlings with a steady hand.

Furthermore, cinnamon can also act against mold lying on the substrate surface. Here, too, it is completely sufficient to sprinkle the cinnamon powder on the substrate in the pot and at the same time to moisten it a little with the watering.

Cinnamon against animal pests and ants

Cinnamon powder on the substrate surface should just as well help against the unpleasant sciarid gnats. The aromatic powder on the substrate surface interrupts the cycle of the small flying animals and prevents them from hatching out of the earth and thus preventing them from multiplying. You can find out more about how to use home remedies to control fungus gnats here.

Cinnamon can also be used against ants (Formicidae). As a powder or 10% oil, it has a deterrent effect on various species of ants. Of course, this has not yet been proven for all types of ants - nevertheless, the spice is ascribed a high potential as a “repellent” (deterrent) for ants. It is definitely worth a try. In order to optimize the effect, any existing pheromone traces must be removed: A sharp, also odor-intensive cleaner is perfectly suited to erase the scent trace on the ant road. Then cinnamon powder or cinnamon oil is applied in strips about 5 cm wide where the ants are undesirable - for example on patio doors, cracks in the wall or on windows. If cinnamon is distributed at the entrance to an ant cave, the colony can also be relocated, so that a nest can be pushed back from the terrace. Here's everything you need to know about how to use cinnamon to fight ants. As an alternative, we recommend our Plantura ant remedy, which not only scares off ants, but also fights them hand-tight.

Cinnamon as a rooting powder and growth inhibitor

In the propagation of cuttings, depending on the species, the rooting of the cuttings can be promoted by dipping the cut surfaces in cinnamon powder. Rapid rooting results and impressive reproduction rates are reported in some places in the hobby area through the use of cinnamon powder. Cinnamon is said to accelerate wound healing and also stimulate root formation. The combination can make cinnamon a real alternative to rooting hormones that are forbidden and not permitted anyway.

On the other hand, it has been found in scientific studies that cinnamon can also have a growth-inhibiting effect on certain plants - such as tomatoes or garden cress. Thus, the use of cinnamon in the garden should be used with caution so as not to inadvertently achieve adverse effects.
