The Nandina, also known as heavenly bamboo, is a popular ornamental shrub valued for its striking foliage and vibrant berries. Proper care throughout the year ensures its health and beauty. This month-by-month care calendar provides a comprehensive checklist to help gardeners maintain their Nandina plants year-round.
January
During January, Nandina enters dormancy in colder climates. Keep the plant protected from harsh winter winds and heavy freezes. Avoid fertilizing now; wait until early spring. Check for any signs of damage or disease and prune dead or damaged branches if necessary.
February
As winter begins to wane, prepare for the upcoming growing season. Prune lightly to shape the shrub and remove any winter-damaged stems. Mulch around the base to conserve moisture and regulate soil temperature. Avoid fertilizing until new growth appears.
March
March signals the start of active growth. Apply a balanced, slow-release fertilizer to encourage healthy development. Water regularly, especially if the weather is dry. Prune to shape the plant and remove any weak or damaged branches to promote airflow.
April
April is ideal for planting new Nandina or transplanting existing ones. Ensure the soil is well-drained and rich in organic matter. Continue watering consistently and mulch to retain moisture. Watch for pests such as aphids or scale insects and treat as needed.
May
During May, Nandina enters its peak growing season. Maintain consistent watering and fertilize monthly with a balanced fertilizer. Prune lightly to maintain shape and remove any seed heads that may appear. Keep an eye out for spider mites and other pests.
June
June offers longer days and warmer weather. Ensure the plant receives adequate water, especially during dry spells. Mulch around the base to conserve moisture. Fertilize if growth seems slow and monitor for pests or diseases.
July
July can be hot and dry; water deeply and regularly to prevent stress. Protect the plant from scorching afternoon sun if necessary. Fertilize once more mid-summer to support continued growth. Remove any dead or damaged foliage.
August
In August, focus on maintaining consistent watering and mulching to keep roots cool. Watch for signs of pests and treat promptly. Prune lightly to maintain shape, and consider dividing the plant if it has outgrown its space.
September
September marks the beginning of fall preparations. Reduce watering as the plant’s growth slows. Apply a slow-release fertilizer to support root development. Prune back to shape and remove seed heads before they mature.
October
October is ideal for final pruning and cleaning up the plant. Protect the shrub from early frosts by mulching heavily around the base. Avoid fertilizing late in the season to prevent new tender growth that could be damaged by cold.
November
In November, Nandina prepares for winter dormancy. Keep the plant protected from cold winds and heavy frost. Water sparingly if the weather is dry, and avoid fertilizing now. Check for any pest issues and address them promptly.
December
December is the coldest month; Nandina remains dormant. Protect the plant with mulch or burlap if temperatures drop significantly. Minimize pruning and avoid fertilizing. Use this time to plan for the upcoming year’s care needs.
