About Anthurium Salgarense

Anthurium salgarense · also called Salgar Anthurium, Colombian Velvet Anthurium · tropical

Anthurium salgarense is a large-growing Colombian aroid with broad, heart-shaped, velvety dark-green leaves and prominent pale veining. A sought-after collector species, it wants warm, very humid, bright-indirect conditions and a loose, airy mix. Give it room to size up; mature leaves can become impressively large in good culture.

Preferred mix: Loose, chunky aroid mix

Watch for — Crispy leaf edges: Driven by humidity dipping below 60% or inconsistent watering. Raise and stabilise humidity, keep the mix evenly moist (not wet) and shield from heating vents and drafts.

Why anthurium salgarense needs this mix

Anthurium Salgarense is a climbing rainforest aroid — it wants a chunky, bark-heavy mix full of air pockets, not a dense soil that packs around its thick roots.

For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons anthurium salgarense struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Using ordinary potting soil with no bark or perlite. Anthurium Salgarense needs roughly half its volume as chunky, airy material — that single change fixes most "mystery decline".

pH — does it matter for anthurium salgarense?

Anthurium Salgarense prefers a slightly acidic mix, around pH 5.5-6.5, which a peat-free compost-and-bark blend lands on naturally. It is not fussy enough to need testing in practice.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

Bagged "aroid mix" is now widely sold and is a fine shortcut for anthurium salgarense, but check it actually contains visible bark and perlite — many are just rebranded compost. Mixing your own from the ratio above guarantees the structure.

Drainage and the pot

Any pot with a drainage hole works because the chunky mix does the draining. A pot only a little larger than the rootball avoids a wet, unused core; add a moss pole and the climbing roots will thank you.

Bark breaks down over time, so refresh the mix for anthurium salgarense every 12-18 months even if the pot size is still fine — spent, sludgy bark is a common hidden cause of decline. When the time comes, our repotting guide for anthurium salgarense covers the timing and technique step by step.
