How to Grow Mahonia Aquifolium?
Growing Mahonia Aquifolium is quite simple if you follow a few key guidelines. Start by selecting a location with partial to full shade, as this plant prefers dappled sunlight. It can tolerate a range of soil types but thrives best in well-drained, acidic to neutral soil.

Plant Mahonia Aquifolium in early spring or fall. Dig a hole twice the size of the root ball and mix the soil with compost to improve drainage. Place the plant in the hole, backfill with soil, and water thoroughly. Mulch around the base to retain moisture and keep weeds at bay. Regular watering during dry periods will help establish the plant.
How to Propagate Mahonia Aquifolium?
Propagating Mahonia Aquifolium can be done through seed or cuttings. For seed propagation, collect ripe berries in late summer, remove the seeds, and sow them in a cold frame or seed tray filled with a mix of sand and peat. Keep the soil moist and provide a cool, shaded environment. Germination can be slow, so be patient.
For propagation by cuttings, take semi-hardwood cuttings in late summer or early fall. Use a sharp knife to cut sections about 4-6 inches long from healthy, mature plants. Dip the cut ends in rooting hormone and plant them in a pot filled with a mix of sand and peat. Keep the cuttings in a humid, shaded environment until roots develop.
Can You Transplant Native Mahonia Aquifolium?
Yes, you can transplant Mahonia Aquifolium, but timing is crucial. The best time to transplant is during the fall or early spring when the plant is dormant.

Water the plant thoroughly after transplanting and monitor it closely for signs of stress.
