How Often Should You Water Lamb’s Ear?

Lamb’s Ear, or Stachys byzantine, is a tough perennial native to Iran, Turkey, and the Caucasus. As you might imagine from its native range, it’s used to growing in dry conditions and so it’s a great addition to a garden in drought-prone regions.

You only need to water Lamb’s Ear plants when the soil has dried out to the depth of its roots. That may take a few weeks, even during a prolonged drought. Applying some mulch to the soil surface can help the soil from drying out in hot, dry conditions.

How Do You Know When Your Lamb’s Ear Plant is Sufficiently Watered?

If your Lamb’s Ear plant needs watering, don’t turn on the sprinkler, as you should try to keep as much moisture as possible off of the leaves. Instead, use a soaker hose or water by hand, pouring it on the soil surface rather than over the foliage. Aim for a cup of water for each plant.

Why is my Lamb’s Ear Droopy?

Does a Lamb’s Ear Need Fertilizer?

In their native environment, Lamb’s Ear plants grow in poor, dry soil, so they don’t require much in the way of fertilizer. Usually, a half-inch of well-rotted compost spread around the plants once in early spring will suffice. However, if the plants are not thriving, try 3 applications of a 5-10-5 fertilizer at 6-week intervals to see if that helps.

Lamb’s Ear plants don’t mind high temperatures, but humidity can create real problems for them.

Will a Lamb’s Ear Survive in the Winter?

Lamb’s Ear plants are reliably winter-hardy from zones 4 to 9. At the southern end of that range, they will stay evergreen throughout the winter, but further north the plant will die back to the ground when cold weather arrives.

Will a Lamb’s Ear Survive in Direct Sunlight?

Lamb’s Ear plants don’t usually mind being in full sun, and in fact, will not do well in full shade. However, where summers are really hot some afternoon shade is appreciated.
