How to care for Horseweed

Water

Horseweed should be watered regularly, allowing the soil to dry out between waterings.

Soil

Horseweed loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Horseweed thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Canadian Fleabane.

Toxicity

Horseweed is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Fertilizer

Once the Horseweed has doubled in size or after a year has passed, it should be moved to a new pot. By replacing the soil with fresh potting soil containing all the vital nutrients, your plant will receive all the sustenance it needs, negating the requirement for fertilizer. It's important to remember that plants get their energy from the sun, not fertilizer.
