Greater plantain thrives in consistently moist soil. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, which can lead to root rot. During hot, dry periods, more frequent watering may be necessary.

Ensure good drainage to prevent fungal issues.

Pruning is typically not necessary for greater plantain unless you are harvesting leaves or managing its spread. If harvesting for culinary or medicinal use, simply cut the desired leaves at the base.

Remove any dead or damaged foliage at any time of year to maintain plant health.

Greater plantain is easily propagated by seed or division. Sow seeds directly outdoors in early spring or autumn.

Division can be done in spring or fall by carefully separating clumps of roots and replanting them in well-prepared soil. It readily self-seeds in suitable conditions.

Repotting is usually only necessary if the plant becomes root-bound in a container or if dividing to manage its spread. If container-grown, choose a pot only slightly larger than the current one.

Repot in spring or fall, ensuring fresh, well-draining potting mix. Water thoroughly after repotting.
