Stipa Tenuissima can be planted in the spring after the last frost until early fall. Look for a spot that gets full sun and has well-draining soil. If you have heavy clay, mix in some organic matter like compost to help with drainage. Space the clumps 2-3 feet apart so the foliage has enough room to spread out. Dig a hole that’s twice as wide and deep as the root ball, then backfill with the native soil. After planting, give it a good watering and add 2-3 inches of organic mulch around the base.
Watering
Once established, Stipa Tenuissima is super drought tolerant and doesn’t need much extra water. During long dry spells, give it infrequent but deep soakings for the best results. The leaves might droop a bit during extreme heat or drought as a way to protect itself, but it will perk up with some water. Just be careful not to overwater, as that can lead to root rot and leaf spot diseases.
Lighting
For optimal growth and flowering, plant Stipa Tenuissima in full sun areas that get at least 6 hours of direct sunlight daily. If it doesn’t get enough sun, the foliage will become thin and leggy. It can handle some light shade, but it might not bloom as much. Stay away from dense shade, as that can lead to floppy growth. Morning sun with afternoon shade is perfect for hotter climates.
Soil
Stipa Tenuissima does best in lean, sandy, well-draining soils and doesn’t need much fertility. If you have clay soil, add compost or well-rotted manure to help with drainage. The ideal pH is between 6.0 and 7.0. Avoid overly rich soils, as they can cause the plant to grow floppy and open. Make sure the soil drains quickly after rain or watering to avoid root rot diseases.
Tips for improving soil:
Mix heavy clay soils with compost
Add horticultural sand to boost drainage
Mulch every year with compost or shredded bark
Fertilization
In early spring, before new growth starts, make sure to use a balanced granular fertilizer. It's best to go for slow-release organic fertilizers, and you can apply them at half strength. If you notice that the leaves look a bit pale during summer, liquid fertilizers can really help give them a boost. Just steer clear of high nitrogen fertilizers, as they can cause weak and floppy growth. If you see too much foliage growth, fewer flowers, or plants that seem more prone to diseases, those are signs that you might be overfertilizing.
