About Swedish Ivy
Plectranthus verticillatus · also called Swedish ivy, Swedish begonia · houseplant
Swedish ivy is a fast-growing, trailing member of the mint family (not a true ivy), prized as an easy, pet-safe houseplant for hanging baskets and shelves. Its one defining need is bright, indirect light with evenly moist but never soggy compost; direct sun scorches its glossy, scalloped leaves and waterlogging rots its shallow roots.
Preferred mix: Free-draining, loam-based potting compost
Watch for — Root rot / wilting: Caused by overwatering or soggy compost; the plant wilts and stems blacken. Often easier to take healthy stem-tip cuttings and start afresh than to save a badly rotted parent.
Why swedish ivy needs this mix
Swedish Ivy is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Swedish Ivy is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons swedish ivy struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates swedish ivy's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for swedish ivy.
pH — does it matter for swedish ivy?
Swedish Ivy is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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
A decent bagged houseplant compost works for swedish ivy as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all swedish ivy needs — the free-draining mix does the rest.
Refresh swedish ivy's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for swedish ivy covers the timing and technique step by step.
