About Begonia 'Picotee Lace Pink'
Begonia × tuberhybrida 'Picotee Lace Pink' · also called picotee lace pink begonia, picotee tuberous begonia · flowering
Begonia 'Picotee Lace Pink' is a tuberous begonia with large, double, ruffled white-to-cream flowers finely edged in rose-pink, the classic picotee look. Grown as a half-hardy annual or lifted tuber, it flowers all summer in partial shade in moist, free-draining soil. Frost-tender, it is stored as a dry dormant tuber over winter.
Preferred mix: Rich, moisture-retentive but free-draining potting compost
Watch for — Tuber rot: Overwet compost or damp winter storage rots the tuber. Use free-draining compost and store dried tubers cool, dry and frost-free.
Why begonia 'picotee lace pink' needs this mix
Begonia 'Picotee Lace Pink' hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Begonia 'Picotee Lace Pink' 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 begonia 'picotee lace pink' 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 begonia 'picotee lace pink' — 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 begonia 'picotee lace pink' dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for begonia 'picotee lace pink'?
Begonia 'Picotee Lace Pink' 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

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.
