How to Plant Red Currants

When to Plant

Plant bare-root red currant shrubs early in the spring before they leaf out, or in the fall to establish roots before winter dormancy.

Selecting a Planting Site

Choose a cool, moist location with good airflow for your red currant shrubs. They can handle full sun or partial shade, but make sure to avoid waterlogged soil.

Spacing, Depth, and Support

Plant red currant shrubs three to five feet apart, with at least 8 feet between rows if planting in rows. Ensure the plants are supported adequately, as they can grow with or without a trellis.

Warning

Red currants were banned in some states due to white pine blister rust, a fungus that affects certain species. Check your local regulations before planting red currants in your garden.

Red Currant Care

Once your red currant shrubs are established, they require minimal maintenance. Here are some tips for caring for your red currants:

Light: Red currants need at least half a day of full sun. In warm climates, they do best with full sun in the morning and partial shade in the afternoon to prevent leaf burn.
Soil: Ensure the soil is well-drained, rich in organic matter, and has good water-holding capacity. Maintain a pH range of 6.2 to 6.5 for optimal growth.
Water: Water established plants regularly, especially during hot, dry periods. Use deep drip irrigation to ensure the shallow roots receive adequate moisture.
Temperature and Humidity: Red currants are winter-hardy but susceptible to late frosts. Avoid temperatures above 85 degrees Fahrenheit and ensure good air circulation to prevent powdery mildew.
Fertilizer: Red currants are heavy nitrogen feeders. Fertilize with a complete fertilizer in the early spring and supplement with composted manure.
Pollination: While red currants are self-fruiting, cross-pollination by insects can increase fruit production.

Types of Red Currants

There are several popular cultivars of red currants, including ‘Red Lake,’ ‘Jonkheer van Tets,’ ‘Stanza,’ ‘Ribes rubrum ‘White Grape,” and ‘Rovada.’ Each cultivar may have different characteristics and flavors, so choose one that suits your preferences.

Red Currants vs. Black Currants

Red currants and black currants belong to the same gooseberry family but are different species. Black currants are sweeter than red currants and fruit on new growth, while red currants produce berries on old wood.

Harvesting Red Currants

Harvest red currants when they turn red and are ripe. Be mindful of wildlife that may enjoy the berries as much as you do. Harvest whole clusters of berries instead of individual berries to avoid damaging the tender skin.

How to Grow Red Currants in Pots

Red currants can be grown in pots with proper care. Use a large pot with good drainage, organic potting mix, and all-purpose fertilizer. Ensure the soil remains evenly moist for optimal growth.

Pruning Red Currants

Prune red currants during dormancy to encourage fruit production on two- and three-year-old canes. Remove diseased, broken, or misshaped canes and maintain a balance of fruit-producing canes of different ages.

Propagating Red Currant Plants

Propagate red currants from healthy plants through tip layering or stem cuttings. You can also grow red currants from seeds, but they require cold stratification before germination.

Common Pests & Plant Diseases

Red currants are susceptible to powdery mildew, currant aphids, leaf spot, and cane blight. Plant resistant varieties, practice proper pruning, and maintain adequate spacing to prevent these issues.

In conclusion, red currants are a versatile, resilient, and rewarding addition to any garden. With proper care and attention, you can enjoy a bountiful harvest of delicious red berries year after year. Whether you are a novice gardener or an experienced green thumb, growing red currants is a rewarding experience that is sure to delight your taste buds and enhance your landscape.
