Year-round
New Mexico olive is a tall, deciduous shrub or small tree that grows to roughly 18 feet by 12 feet. It handles full sun and low water once settled. It comes from drier country than Dallas-Fort Worth, so give it well-drained soil and avoid soggy spots.
- Plant in full sun, or part shade in the hottest spots
- Give it room for about 12 feet wide
- Water deeply but not often once it is established
- On clay, plant slightly high so water drains away from the trunk
Grows large, so give it room and prune lightly to keep an even, tidy shape near a front walk.
Fall
Leaves turn yellowish and drop, showing the pale gray trunks. Fall is a good time to plant.
- Plant new shrubs while the soil is still warm
- Water deeply after planting, then taper off
- Rake fallen leaves into a mulch layer
- Skip fertilizer
Winter
The bare gray branches are the winter look. It is listed as very cold hardy, so freezes in Dallas-Fort Worth are not a concern for it.
- Do not water unless winter stays very dry for weeks
- Prune dead or crossing branches while it is bare
- Leave the shrub without wrapping or covers
- Watch for wet, heavy clay around the base
Spring
Small yellow flowers show up very early, often in late winter, before leaves fill in. New growth follows.
- Plant new shrubs in early spring or fall
- Water deeply about once a week for the first season
- Prune after flowering if you want to shape it
- Skip heavy fertilizer
Summer
Established shrubs handle heat well but appreciate an occasional deep soak in long dry spells. Female plants form dark blue fruit late in the season.
- Water deeply every 2 to 3 weeks in dry weather
- Young plants need a deep soak weekly
- Keep mulch a few inches from the trunk
- Expect some fruit drop under female plants
