Answer: The easiest way to propagate blackberries is with root suckers. These are new canes that grow from the roots a short distance from the main crown of the bramble. While plants are dormant, sever the root connection to the main plant with a sharp spade, and remove the sucker with plenty of roots and soil.<br><br>Prepare the soil ahead of time. To produce well, most blackberries require full sun (though I've seen huge wild brambles produing pounds of berries in dappled shade). The soil should be high in organic matter (humus), so work in lots of compost and/or aged manure. Such a soil drains well yet holds moisture on the organic particles. Mulch with straw after planting. The plants will need extra attention during this period of settling in. Check soil moisture often, and water if soil feels dry in the root zone, and keep adding mulch if weeds start to pop through.
