Spring: The ideal time to plant Alcea rosea ‘Spring Celebrities Carmine Rose’ is in spring, as the soil warms up. Planting in spring helps the roots establish quickly, ensuring healthy growth and vibrant blooms during the flowering season.

Site Selection
Sunlight: Alcea thrives in full sun. Select a location that receives at least six hours of direct sunlight daily to support vigorous growth and abundant flowers.
Soil: Choose well-drained soil for Alcea rosea ‘Spring Celebrities Carmine Rose’. It does not tolerate waterlogged conditions, so improving soil drainage with organic matter like compost or grit is essential for keeping the plant healthy and preventing root rot.

Prepare the Hole: When planting your Alcea, dig a hole that is twice as wide as the root ball and as deep as the plant’s container. This provides enough space for the roots to spread and establish well.

Planting: Position the plant in the hole, ensuring the top of the root ball is level with the surrounding soil. Gently backfill, pressing the soil down to eliminate air pockets.
Watering After Planting: Thoroughly water your Alcea after planting to settle the soil and help the roots establish. Ensure the planting area drains well to avoid waterlogged conditions.
