About Impatiens balsamina
Impatiens balsamina · also called Garden Balsam, Rose Balsam · flowering
An old-fashioned upright annual impatiens grown from seed, bearing camellia-like double flowers in pink, red, purple and white clustered tight against the stems. Easy and fast-growing, it flowers all summer in sun to part shade and self-seeds freely. Its name 'Touch-me-not' comes from ripe seed pods that burst explosively when touched, scattering seed.
Preferred mix: Rich, well-drained, moisture-retentive soil
Watch for — Wilting in heat or drought: Plants flag quickly when the soil dries out, especially in full sun. Keep soil evenly moist, mulch around them and provide light afternoon shade in hot climates.
Why impatiens balsamina needs this mix
Impatiens balsamina hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Impatiens balsamina comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons impatiens balsamina struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for impatiens balsamina — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets impatiens balsamina dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for impatiens balsamina?
Impatiens balsamina prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
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 good peat-free houseplant compost works for impatiens balsamina straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh impatiens balsamina's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for impatiens balsamina covers the timing and technique step by step.
