VEGETABLE PATCH : The soil feels alive underfoot this morning — a descending moon in a root phase is exactly the right combination to get your underground crops moving. Sow parsnip (Pastinaca sativa ‘Tender and True’, ‘Hollow Crown’) directly in place in rows 30 cm apart, seeds 1 cm deep in groups of three then thinned to the strongest; parsnips need a long season, so every day counts now / Transplant celeriac (Apium graveolens var. rapaceum) seedlings started under cover into prepared beds, spacing them 35 cm each way and burying the crown just at soil level — planting too deep encourages rot rather than swelling / Sow scorzonera (Scorzonera hispanica) and salsify (Tragopogon porrifolius) in drills 20 cm apart, 2 cm deep; these underused roots thrive in light, stone-free soil and reward patience with a genuinely distinctive flavour / If you have beetroot (Beta vulgaris ‘Chioggia’, ‘Boltardy’) seedlings ready in modules, now is a fine moment to transfer them outdoors, 10 cm apart in rows 30 cm apart, watering in with a gentle rose / On sandy soils, work in a handful of well-rotted compost per planting station before sowing to improve moisture retention around developing roots.

INDOORS : Carrot (Daucus carota ‘Nantes 2’, ‘Chantenay Red Cored’) seedlings sown in deep trays under glass are ready for their first thin if they’ve reached 3–4 cm — remove the weakest to leave one plant every 4 cm, using scissors rather than pulling to avoid disturbing neighbours / Check the compost moisture in radish (Raphanus sativus) and turnip (Brassica rapa) trays: roots swell unevenly when watering is erratic, so aim for consistently moist but never waterlogged conditions / Kohlrabi (Brassica oleracea var. gongylodes ‘Kolibri’, ‘White Vienna’) started indoors can be hardened off this week by moving trays outside for a few hours each afternoon, gradually extending exposure — this toughens cell walls and reduces transplant shock.

LANDSCAPING : A root day isn’t only for the kitchen garden. Divide and replant established clumps of ornamental grasses such as Miscanthus sinensis or Pennisetum alopecuroides that have grown congested at the centre — slice through the rootball with a sharp spade, replant vigorous outer sections 40–50 cm apart and water in well; dividing now encourages strong new root growth before summer heat arrives / Work a 5 cm layer of composted leaf mould into borders where you plan to establish perennials, forking it in to a depth of 20 cm; this improves soil structure and feeds the microbial life that supports healthy root systems across the whole bed.
