Rhododendron hybrid 'Minnetonka'

Rhododendrons grow best in cooler areas where they are not exposed to hot afternoon summer sun. They like slightly moist, acidic soil.

Apart from its stunning purple flowers, the Minnetonka also has deep glossy leaves that are specular throughout the winter months. Low maintenance, the Minnetonka has a compact shape, 3-6 feet tall and wide, that works well in a manicured garden. Clusters of vibrant color, these blooms emerge from a dark center and will surely attract bees, butterflies and birds.  It is cold hardy to -10° F.

Pollination and Ripening

Rhododendrons will produce their large, showy blooms each spring without any pollination. The flowers are formed from buds that develop the previous year (prune them after they are finished flowering), so they will bloom naturally even if no pollen reaches them. If you want the plant to produce seeds, it needs pollen from another flower. Most rhododendrons are self-fertile, meaning a single plant can pollinate itself, but cross-pollination between two different plants often produces more seeds.

Planting Guide

Planting Guide for Rhododendrons

Site Selection:
Choose a location that offers partial shade to full shade, with well-draining soil. Avoid areas with strong winds or extreme sunlight exposure.

Time of Year to Plant:
Plant rhododendrons in the spring or fall. Avoid planting during the hottest part of the summer or during freezing temperatures in winter.

Spacing:
Space rhododendrons according to their mature size, typically 2 to 6 feet apart, depending on the variety.

Soil Type:
Rhododendrons prefer acidic soil with a pH range of 4.5 to 6.0. Ensure the soil is rich in organic matter and well-draining.

Planting:
Dig a hole twice as wide as the root ball and slightly shallower than the root ball's depth. Place the rhododendron in the hole, ensuring the top of the root ball is level with the ground. Backfill the hole with soil, lightly tamp it down, and water thoroughly.

Watering:
Keep the soil consistently moist, especially during the first growing season. Water deeply and infrequently, allowing the soil to dry out slightly between waterings.

Fertilizing:
Apply a balanced, slow-release fertilizer formulated for acid-loving plants in the spring after the last frost. Follow the manufacturer's instructions for application rates.

Care Through the Seasons:

  • Spring: Monitor for signs of new growth and adjust watering and fertilizing accordingly. Remove spent flowers after blooming.
  • Summer: Mulch around the base of the plant to retain moisture and suppress weeds. Water during dry spells.
  • Fall: Apply a layer of mulch to protect the roots from winter cold and moisture fluctuations.
  • Winter: Protect rhododendrons from extreme cold and drying winds by wrapping them with burlap or providing a windbreak.

Preparing to Plant:
Before planting, amend the soil with organic matter such as compost or peat moss to improve drainage and fertility. Test the soil pH and adjust it if necessary.

Managing Pests and Diseases:
Keep an eye out for common pests such as aphids, lace bugs, and spider mites. Treat
infestations promptly with insecticidal soap or neem oil. Watch for signs of diseases such as powdery mildew or root rot, and ensure good air circulation around the plant to prevent fungal issues.

Keeping Them Healthy:
Regularly monitor the health of your rhododendrons by inspecting leaves for signs of
discoloration, wilting, or pest damage. Provide proper care, including watering, fertilizing, and pruning, to keep the plants healthy and vigorous.

Choosing Rhododendrons:
When selecting rhododendrons for your garden, consider factors such as mature size, flower color, bloom time, and growth habit. Choose varieties that suit your climate, soil conditions, and desired aesthetic.
