This growing advice helps you choose. Your variety, growth stage, weather and conditions in your space determine the actual timing.

A good start

Sowing under cover and raising seedlings

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.

Germination and temperature
Wait for workable, warmed soil; follow the cultivar’s minimum sowing temperature.
After emergence
Keep the seed row evenly moist during emergence and identifiable with a label.
Pricking out and potting on
Do not prick out. Thin in place; transplanting can damage the taproot.
Hardening off and planting out
Stays where sown; hardening off and planting out are unnecessary for direct sowing.

Use deep soil with little compaction. A warm tray in the loft is not a suitable propagation route for this root crop.

How to grow carrot

The options below belong to the plant. From these, choose the method that suits your variety's growth habit.

Sowing directly into a cleared bed

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.

  1. Remove stones, weeds and hard clods without smearing wet clay into a compacted surface.
  2. Sow at the depth for the cultivar and keep the germination zone moist.
  3. Thin in time and harvest a first test specimen.

For anyone with a suitable bed and enough root space.

A small trial in a suitable container

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.

  1. Check the cultivar’s expected root size.
  2. Choose a container with enough depth and unobstructed drainage.
  3. Sow directly and check moisture more often than in the ground.

For limited space, provided the container suits the root shape.

Take a closer look

A tidy row starts with thin sowing

Spread the fine seed along a shallow drill. Gently cover it with soil and keep the surface moist until seedlings appear.

Choose a round root deliberately

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.

Consider why this variety suits the position

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.

Sow where you want to harvest

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.

Give the container a practical position

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.

Check the surface if germination is slow

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.

Keep maintenance small and regular

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.

Store undamaged carrots in suitable conditions

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.

Compare your pot with your own bed

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.
