About Sweet 100 Cherry Tomato
Solanum lycopersicum 'Sweet 100' · also called Sweet 100 tomato, Sweet 100 cherry · edible
'Sweet 100' is a vigorous indeterminate cherry tomato famed for very high sugar levels and enormous yields of small, round, intensely sweet red fruit borne in long branching trusses of a hundred or more. The tall vines crop prolifically from midsummer until frost. A frost-tender warm-season annual needing full sun, support and steady moisture.
Preferred mix: Rich, fertile, well-drained loam
Why sweet 100 cherry tomato needs this mix
Sweet 100 Cherry Tomato is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Sweet 100 Cherry Tomato grows fast and has a big crop to fill, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons sweet 100 cherry tomato struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves sweet 100 cherry tomato — growth stalls, leaves pale, and yields collapse.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Sweet 100 Cherry Tomato needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for sweet 100 cherry tomato?
Sweet 100 Cherry Tomato does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
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
For containers a good multipurpose or vegetable compost works for sweet 100 cherry tomato with extra feed through the season. For beds, the real win is digging in plenty of well-rotted compost or manure — that beats any bag.
Drainage and the pot
Rich but free-draining is the target: raised beds and large containers both deliver it. Mulch heavily to even out moisture and roughly halve how often you water.
