Caring for Leptinella Plants

New Zealand brass buttons plants are extremely low-maintenance.  Being the perfect filler for pathways and narrow corridors, all you need to do is water them regularly and mow them regularly to avoid overgrowth.

Here’s a quick rundown on how to take care of this evergreen herbaceous groundcover.

Light and Temperature

Brass buttons is hardy in USDA zones 7 through 9. It needs a decent amount of sunlight. If you live in cooler climates, a preferable location would be somewhere that gets at least 6 hours of sunlight per day. However, in hotter climates, brass buttons tend to grow better in partial shade.

In drought and intense heat, brass buttons may die back. The same goes for extreme cold, or general winters in cooler climates. Keeping the soil adequately moist should assist with keeping the plant alive in either condition, and it may remain evergreen in good conditions.

Water and Humidity

You’ll have to water your brass buttons frequently. They’re intolerant to drought and depend on regular watering for survival. They’re shallow-rooted plants, so any period of dry soil is enough to kill them. Keep the soil moist, and increase watering in hot summers that may include drought.


These plants are tolerant almost any kind of soil. However, the most critical requirement for its growth is to have well-draining soil. They prefer slightly acidic soil that’s rich in organic matter, but remain adaptable to other soil types including alkaline and neutral pH soil.

It may not grow as well in compacted, heavy clay soil. You’ll need to amend the soil before planting brass buttons again.


Once your plant is well-established, only then you should fertilize it. Use a half-strength, all-purpose fertilizer once or twice per year. You can fertilize the plant in early spring and then in early summer. Don’t worry about fall or winter fertilizing, as the growth rate slows down during those seasons.

Repotting the Brass Buttons Plant

Repotting is easy, as they’re hardy to intensive handling. You can move them from container to container in early spring without a problem, as well as dig them up from certain areas of your yard and transplant them in others. They should spread quickly.

Brass Buttons Plant Propagation

Once established, these plants are crazy growers and can spread quite fast. You may want to propagate it by division, splitting up the bunches and sowing them in different locations in your yard. The best season to propagate brass buttons is spring or early fall. Make sure to space the plants 9-12” apart when sowing.

Pruning the Brass Buttons Plant

To prevent overgrowth, thin 2-3 times per year. You can use a lawn mower for larger surfaces and pruning shears for smaller containers.


If you’re addressing their water needs and fertilizing them well, you shouldn’t have too many problems with this plant. However, there are a few things you need to watch out for.

Growing Problems

Climate can affect plant growth. If you are living in a place that is dry, you’ll need to water brass buttons quite frequently to keep them in their original condition. Similarly, for light soils, regular watering is a must. Also, they have a tendency to spread indefinitely. You have to remain vigilant in pruning them to keep them from overtaking your garden.

Pests and Diseases

Brass buttons are generally pest-free. You’re unlikely to face any problems related to pest or diseases.
