About Eccremocarpus scaber

Eccremocarpus scaber · also called Chilean glory flower, Chilean glory vine · flowering

Eccremocarpus scaber, the Chilean glory flower, is a fast, evergreen-to-herbaceous tendril climber bearing tubular orange-red (sometimes yellow or pink) flowers from late spring to autumn. Often grown as a half-hardy annual in cooler areas, it climbs by leaf tendrils and quickly clothes trellis or wires in a sheltered, sunny spot. It is much loved by bees.

Mature size: Around 3-5 m in a season, covering trellis, wires or an obelisk.

Watch for — Poor flowering in shade: Too little sun gives lush leaves but few flowers. Site in a full-sun, sheltered position and feed with a high-potash fertiliser.

How to tell eccremocarpus scaber needs repotting

Repotting on a calendar is less reliable than reading the plant. For eccremocarpus scaber, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot eccremocarpus scaber on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot eccremocarpus scaber

Pot on seedlings as they grow; not a perennial repot. Eccremocarpus scaberis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Fast scrambling climber that grips by branched leaf tendrils; evergreen in mild winters, often cut back or grown as a half-hardy annual in colder gardens..

What size pot to step eccremocarpus scaber up to

Pot eccremocarpus scaber on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot eccremocarpus scaber

Pot eccremocarpus scaber on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting eccremocarpus scaber

Pot on before it is root-bound. Check eccremocarpus scaber regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh fertile, free-draining soil at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water eccremocarpus scaber in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for eccremocarpus scaber

Eccremocarpus scaber wants fertile, free-draining soil. Grows best in moderately fertile, moist but well-drained soil of any pH. Add grit to heavy ground; in pots use a free-draining, loam-based compost. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting eccremocarpus scaber — frequently asked questions

How often should you repot eccremocarpus scaber?

Pot on seedlings as they grow; not a perennial repot for eccremocarpus scaber. Eccremocarpus scaber is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into fertile, free-draining soil so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does eccremocarpus scaber need?

When is the best time of year to repot eccremocarpus scaber?

Can you put eccremocarpus scaber straight into a much bigger pot?

No. Even a fast-growing eccremocarpus scaber should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise eccremocarpus scaber after repotting?

Not immediately. Wait about 1 week after repotting eccremocarpus scaber. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
