How to fertilize Milfoil

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 itâs likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Milfoil after it doubles in size or once a yearâwhichever comes first.

Milfoil is generally considered an easy-to-care-for plant and makes a great choice for beginners!
Water Needs
Milfoil 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
Milfoil requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive đȘ. Select your region to see how the current weather in your area affects the placement in your home đĄ.
Toxicity
Milfoil is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.
Soil
Milfoil 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
Milfoil grows very slowly and doesnât require added fertilizer. Replacing your plantâs potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
Growth Pattern
Milfoil grows vertically and new growth will emerge from the top of the plant.
Growing Outdoors
USDA Hardiness Zone
Milfoil can be grown outdoors in USDA Hardiness Zones 3a-9b. Find your local hardiness zone here.
Propagation
Milfoil can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot
