Plant Propagation by Division
Explore the work of people investigating, documenting and teaching about plants, ecosystems and environmental change.
Shanti Plants - The Earth Provides

Division separates an established plant into smaller living sections that already contain roots, shoots or viable growing points. It can renew crowded clumps and produce mature plants faster than seed, but only when the plant's structure and seasonal growth cycle make division appropriate.
What This Index Covers
This index covers clump-forming perennials, grasses, bulbs, rhizomes, tubers, suckers and offsets; timing; lifting; identifying natural separation points; reducing damage; replanting; watering; hygiene and recovery. It excludes destructive separation of plants that do not tolerate division and any collection that lacks permission.

Plants suited to division - Understanding crowns, clumps, offsets, bulbs, rhizomes and suckers.
Timing and preparation - Matching division to dormancy, active growth and local weather.
Lifting and separating - Protecting viable roots, buds and crowns while limiting wounds.
Replanting - Restoring correct depth, orientation, soil contact and water.
Recovery and monitoring - Watching for dehydration, rot, instability and delayed growth.
Hygiene and sharing - Cleaning tools and avoiding movement of pests, pathogens and weeds.

Coverage and Evidence
Division guidance must be tied to the actual species and growth form. A visible clump does not always mean that every section can survive independently. Observe plant health and local season, and retain enough roots and growing points for recovery. Where plants are wild, protected, culturally significant or not yours, obtain permission and check legal requirements before disturbance.
The Earth's Resource Map and Learn library are being built progressively. Indexed means that a topic or resource can be connected to its identity, source and broad context; it does not mean that every claim has been verified or localised. Evidence is assessed claim by claim. Where information is missing, uncertain, restricted or location-dependent, that limitation should remain visible.
