Parmex forms small, round carrots. Discover when this variety makes sense for heavy or stony soil and how to approach pots, emergence and harvesting practically.
This image was created with AI from described plant characteristics and growing advice. It shows a possible situation and is not a photograph of a verified cultivar.
This growing advice helps you choose. Your variety, growth stage, weather and conditions in your space determine the actual timing.
Sow directly · Carrot
Late winter–spring, only with a suitable early cultivarSow directly into the final greenhouse soil or deep container; do not transplant later.
Use deep soil with little compaction. A warm tray in the loft is not a suitable propagation route for this root crop.

Guideline periods for the Netherlands and Flanders. Check the variety, available light, soil and measured temperatures. Greenhouse heating does not guarantee enough winter light.

A root builds its harvest underground. First choose workable soil and a spot that will stay available for long enough. Sow directly and keep the row identifiable, even while seedlings are still small.
For anyone with a suitable bed and enough root space.

Choose a pot clearly deeper than the expected root and start with a suitable short or round variety. Sow directly and thin. Loose filling and drainage holes give roots more chance than hard, wet garden soil in a small pot.
For limited space, provided the container suits the root shape.

Spread the fine seed along a shallow drill. Gently cover it with soil and keep the surface moist until seedlings appear.
View your supplies →RHS describes Parmex as small and round, with carrots five to seven centimetres long: length, not diameter. Expect differently from long carrots. For small meal-sized roots, first make room for a manageable trial row.
According to RHS, Parmex suits heavy or stony soil where long carrots may branch. Drainage still matters. Consider site and variety together, comparing root room with described shape rather than blaming all soil irregularities on the cultivar.
Start seed in its final position, including pots. Minnesota warns of young carrot taproot damage during transplanting. Label the sowing so you can await emergence without repeatedly disturbing the surface to search.
The RHS explicitly mentions pots for Parmex. General guidance considers round carrots suitable for many containers. Keep pots accessible for care. Compare internal space and drainage before sowing; a variety name alone sets no universal pot size.
Hard crusts hinder small seedlings. Minnesota describes gentle fine-spray moistening to help emergence. Inspect surfaces before resowing. Record findings rather than automatically blaming slow starts on poor seed or unsuitable varieties.
Hand-weed carefully near carrots to reduce damage. Pots dry faster and need more frequent moisture checks. Assess actual conditions before watering. Plan maintenance when observation is easy; full pots must remain accessible.
Handle harvests gently and separate damaged carrots from intact storage roots. Minnesota gives cold, moist storage without foliage. Household fridges and suitable stores differ. Check quality throughout; general storage guidance is no variety-specific keeping guarantee.
Note your chosen position, usable carrot numbers and experience of the round shape. Save Parmex's name with observations and photos. Record later bed growing separately to assess whether pots or open ground better suit your care.
