Plant hardy orange in spring or early fall, with the flare at grade, and keep it off the walk because the thorns are sharp.

Plant in spring or early fall, and keep it off the walk
| Factor | Recommended | Avoid |
|---|---|---|
| When | Spring, or early fall while the ground is still workable | Do not plant into frozen ground or a hard freeze week |
| Site | Full sun, off walks, play areas, and doorways | Do not set it where people brush the thorns |
| Room | About 8 to 15 feet for a specimen; closer in a row for a barrier hedge | Do not crowd a specimen against a house or a path |
hardy orange is a nursery shrub or small tree, not a grocery orange you set like a tender citrus. Give it sun, and leave room for an 8- to 20-foot plant if you want a specimen. [1] A barrier hedge can sit closer in a row and stay shorter if you shear it. Either way, keep the thorns off the walk, a doorway, and a play area, because people brush those spots every day. [2] A young plant in a colder garden does better on the sheltered side of a building or a windbreak until the bark thickens. [3] Do not plant it next to foot traffic. The thorns are the point of a barrier, not a patio edge. [4]
When should I plant hardy orange?
In spring, or in early fall while the ground is still workable. Keep it off the walk.
How to set a hardy orange in the ground
Dig the hole first, then slide the plant out and set the flare at the soil line.
- Water the pot, then ease the plant out. Tease circled roots and cut any that girdle the ball.
- Dig a hole no deeper than the root ball, and about twice as wide.
- Set the flare at the soil line. Backfill with the native soil, and firm it gently.
- Water to settle the hole. Mulch the surface, keeping bark off the stem. Leave a specimen well off a walk; set a hedge in a row so the thorns knit.
How far apart do I plant a hedge?
Leave about 8 to 15 feet for a specimen. A barrier hedge is planted closer in a row, then sheared. Keep either planting off the walk.
Set it in spring or early fall, with the flare at grade, and keep the thorns off the walk.
