Planting & Care Instructions

Where to Plant

Sunlight: These perennials thrive in full to partial shade, requiring about 2 to 4 hours of filtered light. In hotter climates, protect them from harsh afternoon sun to prevent the deep red plumes and foliage from scorching or drying out prematurely.
Soil: They prefer rich, organic soil that stays consistently moist but never soggy. If you have heavy clay, mix in plenty of compost or peat moss to improve drainage while retaining the moisture these plants crave.

Watering Requirements

For the first year, water your Montgomery Astilbe two or three times a week to ensure the roots settle into their new home. Once established, they need about one inch of water per week, as they have zero tolerance for drought and will wilt quickly if the soil dries out. If they do not get enough water, you will notice the leaf edges turning brown and the flower spikes becoming stunted.

Pruning Tips

Since these bloom on new wood produced during the current growing season, you should wait until early spring to cut the old foliage back to the ground. Leaving the dried flower heads and leaves through winter provides a natural mulch that protects the crown from freezing temperatures. Think of it like a winter coat that you only remove once the threat of a hard frost has passed.

Fertilizer Needs

Apply a balanced, slow release fertilizer in early spring just as the new green shoots begin to emerge from the soil. Avoid using high nitrogen fertilizers late in the summer because this encourages tender new growth that will be easily killed by the first frost. A single application of a general purpose food is usually enough to fuel those brilliant crimson blooms.

#ProPlantTips for Care:

This Astilbe variety is most successfully grown in a shady area but can tolerate some morning sun. A moist, well-drained location is ideal for this plant, as it's best to prevent the Montgomery Astilbe from drying out, providing consistent moisture throughout the growing season. Mulch can be spread around the base of the plant to help retain soil moisture and reduce water evaporation.

In order to keep Astilbe looking its best for the next year, it's recommended to avoid cutting it back in the winter, as the old foliage helps protect the plant from winter damage. It's best to prune in early spring before the new growth begins.
