Intercropping
/ˌɪntərˈkrɑpɪŋ/
Definition
Intercropping is a cropping technique in which 2 or more plant species or varieties are grown together in the same area at the same time. Unlike crop rotation, which uses the same ground in sequence, intercropping overlaps the crops in space and time. The plants may be arranged in mixed, row, or strip patterns, as long as they share part of the growing period in one field, bed, or plot.
Use in Gardening
- Resource sharing: It can help plants use light, water, and soil nutrients more completely when paired species root at different depths or grow to different heights.
- Pest and disease pressure: Mixed plantings may slow the spread of some pests and diseases by breaking up large blocks of one host plant, though results depend on crop choice and spacing.
- Soil support from legumes: When one partner is a legume, root-associated bacteria can fix nitrogen, turning nitrogen gas into plant-available forms that may support the surrounding planting over time.
- Garden planning needs: Successful use depends on matching growth rate, mature size, and shade tolerance so one crop does not outcompete the other for space or sunlight.
