PLANTING and AFTERCARE GUIDE
Best Time to Plant
Spring: The ideal time to plant Alchemilla mollis is in spring when the soil is warming up. Planting during this time gives the plant plenty of opportunity to establish strong roots before the flowering season begins.
Autumn: Alternatively, planting in early autumn allows Alchemilla mollis to settle in and prepare for the following year. Ensure the plant has time to establish before winter sets in.
Site Selection
Sunlight: Alchemilla mollis thrives in both full sun and partial shade. If planted in full sun, it will need more moisture to stay healthy, but it performs equally well in partial shade, making it a versatile choice for various garden settings.
Soil: Choose a site with moist, well-drained soil. Alchemilla mollis prefers consistently moist soil but does not tolerate being waterlogged. If necessary, amend your soil with compost to improve drainage and nutrient content.
Planting Instructions
Prepare the Ground: Dig a hole that is about twice as wide as the root ball but just as deep. This will give the roots of the plant room to spread out and grow robustly.
Soil Enrichment: Before placing the plant, mix compost or organic matter into the soil to improve fertility and drainage. Alchemilla mollis benefits from enriched soil for optimal growth and flower production.
Planting: Set the plant in the hole so that the top of the root ball is level with the surrounding soil. Backfill gently, pressing the soil around the base to eliminate air pockets.
Watering: After planting, water Alchemilla mollis thoroughly to help the roots settle. Keep the soil consistently moist during the initial growth phase to support root establishment.
Watering Guidelines
During Growth: Keep the soil evenly moist throughout the growing season. Alchemilla mollis prefers regular watering, particularly during dry spells. Mulching around the plant can help retain moisture and keep the roots cool.
Dormant Period: In winter, reduce watering significantly, as Alchemilla mollis becomes dormant. Only water if the soil becomes very dry during an unseasonably warm spell.
Feeding
Spring Fertilising: To boost growth and flower production, apply a balanced fertiliser in early spring. This will provide essential nutrients to support healthy foliage and vibrant blooms.
Summer Feed: If necessary, provide a light feed mid-summer to ensure Alchemilla mollis continues producing abundant flowers throughout the season.
Pruning and Maintenance
Deadheading: Regularly deadhead the spent blooms of Alchemilla mollis to encourage new flower growth and maintain a tidy appearance. This will also help prevent the plant from self-seeding excessively.
End of Season Pruning: At the end of the flowering season, cut back the foliage of your Alchemilla to ground level. This will prepare the plant for dormancy and promote healthier growth in the following spring.
Mulching
Spring Mulch: Apply a layer of organic mulch, such as compost or well-rotted manure, around the base of Alchemilla mollis in early spring. This will help retain soil moisture, suppress weeds, and regulate soil temperature.
Winter Mulch: During the colder months, mulching can help protect the roots of Alchemilla mollis from frost damage. This is especially helpful in colder regions where frost may heave the soil.
Supporting the Plant
Alchemilla mollis generally has a low, spreading habit and does not require staking. However, in areas prone to heavy rainfall or strong winds, the plant’s delicate flowers may benefit from light support to prevent drooping.
Final Tips
Alchemilla mollis is a hardy, low-maintenance perennial that adds charm to any garden. It is easy to grow and perfect for gardeners of all experience levels. By providing Alchemilla mollis with the right conditions—moist, well-drained soil and a balance of sun and shade—you’ll enjoy its attractive foliage and frothy blooms from June to September. Incorporate Alchemilla mollis into garden borders, pathways, or as ground cover for a lush, eye-catching display.
