How to fertilize Black Broom

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Black Broom after it doubles in size or once a year—whichever comes first.

Black Broom prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
Sunlight Needs
Black Broom requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
Toxicity
Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.
Soil
Black Broom does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Fertilizer
Black Broom is a fast growing plant and may deplete the nutrients in its soil over time. Replenish them with a gentle organic fertilizer or compost every 1-2 months depending on your location and season. Fertilize more often during the growing season and in warmer and brighter climates.
