Pollination Information for Black Hat Rhododendron (Rhododendron x 'NCRX2')

The Black Hat Rhododendron (Rhododendron x 'NCRX2') is a hybrid cultivar that is created by cross-breeding two different species of rhododendron. As such, it is not self-fertile and requires cross-pollination with another rhododendron plant to produce viable seeds.

The Black Hat Rhododendron blooms in the late spring or early summer, producing showy clusters of deep pink to purple flowers. The flowers attract bees, butterflies, and other pollinators, which transfer pollen from the anthers to the stigma of the flowers, allowing for fertilization to occur.

It's important to note that not all rhododendron species are compatible with each other for pollination purposes. To ensure successful pollination of the Black Hat Rhododendron, it is recommended to plant other rhododendron cultivars from the same group, such as the Purple Splendor or Catawba Rhododendron, nearby.

Another option for pollination of the Black Hat Rhododendron is hand-pollination. This involves manually transferring pollen from the anthers of one flower to the stigma of another flower using a small brush or cotton swab. Hand-pollination can be a useful technique for ensuring successful fertilization and seed production in hybrid cultivars like the Black Hat Rhododendron.

Overall, the Black Hat Rhododendron requires cross-pollination with another rhododendron plant to produce viable seeds. Planting other rhododendron cultivars from the same group or using hand-pollination techniques can help ensure successful fertilization and seed production.

Planting & Care for Black Hat Rhododendron

Planting

1. Choose a partially shaded location with well-draining, acidic soil (pH 4.5-5.5).
2. Amend the soil with organic matter and horticultural acid to lower the pH if needed.
3. Dig a hole twice the width of the root ball and as deep as the root ball.
4. Loosen any roots that are circling the root ball and place the plant in the hole.
5. Backfill the hole with amended soil and water well.
6. Mulch around the base of the plant to retain moisture and suppress weeds.

Care

1. Water the plant deeply once a week, more often during hot, dry weather.
2. Fertilize in early spring with a slow-release, acid-loving fertilizer.
3. Prune after the plant has finished blooming to maintain its shape and remove any dead or damaged wood.
4. Protect the plant from strong winds, which can damage the foliage and reduce flowering.
5. Monitor for pests and diseases, such as leaf spot and spider mites, and treat as necessary.
