Asparagus
Plant
March–April. Plant ten one-year old crowns 15–20cm deep, 30cm apart in a single well-prepared row
Harvest
May–June
Likes
Very well-drained and slightly alkaline soil, clear of weeds, seaweed fertilizer
Dislikes
Cold and wet conditions, slugs
Varieties
Connover’s Colossal, Backlim, Gijnlim
Tips
Although slow to start, once established these perennial plants are trouble-free and last for up to twenty years. Parsley can be grown between crowns.
Broccoli
Sow
March–May (under cover for first month). Plant in 2–3 batches of 10–20 small plants, about 20–40cm apart (depends on variety) in rows
Harvest
June–October (Calabrese); January–April (purple sprouting)
Likes
Nitrogen-rich soil, sheltered site, lots of space (purple sprouting)
Dislikes
Slugs, snails, white fly – might need protecting from pests with netting
Varieties
Early Purple Sprouting Improved, Belstar (Calabrese)
Tips
Can suffer from disease “clubfoot”, which remains in soil for up to twenty years
Leeks
Sow
Grow small (15cm) plants from seed indoors, ready for planting out into deep, narrow holes in June; sow seeds outside in May with 10cm between plants.
Harvest
September–May
Likes
Sun, water
Varieties
Musselburgh (very hardy, dates back to 1834), Apollo
Tips
“Earth up” the emerging leek with soil to increase amount of white stem. Closer spacing of plants produces smaller leeks
Lettuce
Sow
Germinate seeds indoors for planting out February–September
Harvest
All year
Likes
Very rich soils with lots of nitrogen
Varieties
Cos: Corsair, Little Gem (takes over two months to develop a heart). Loose-leaved: Lollo Rosso, Lamb’s lettuce (small rounded green leaves), Catalogna (serrated leaves), Salad Bowl (green and dark red oak leaves)
Potatoes
Sow
Earlies March–May; maincrop mid to late April. Plant chitted potatoes 40cm apart into a 25cm deep, 30cm wide trench with dug-in manure at its base
Harvest
When flowers die down, the potatoes are ready to pick. Earlies: June–July. Maincrop: September (store over winter in a cool, dry environment)
Likes
Rich soil and potash (wood ash from stove or potash-rich comfrey); regular watering while flowering
Dislikes
Shade, frost, blight fungus
Varieties
First earlies: International Kidney (aka Jersey Royals). Second earlies: Kestrel or Wilja (high yield and good disease resistance); Charlotte (classic French salad potato). Maincrop: Belle de Fontenay (old French early main crop); Santé (excellent for organic growers as very resistant to pests and disease)
Tips
“Earthing up” the plants stops the tubers being ruined by sunlight and turning green. To do this, cover the plants with soil until only 10cm or so of foliage is visible. Expect to do this a few times each growing season

Rocket
Sow
All year round indoors; in summer outside
Harvest
All year, 3–4 weeks after sowing
Dislikes
Bolts (flowers) in hot weather
Varieties
Avanti
Tips
Very easy to grow; minimal pest problems
More on growing rocket
Spinach
Sow
Regular small sowings every three weeks from March–September
Harvest
April–November
Likes
Cool conditions
Varieties
Galaxy, Bloomsdale
Tips
Can bolt (flower) in hot weather. If you’re having problems try chard (also known as “perpetual spinach”) instead.
Tomatoes
Sow
Seeds (March–April) for planting out as small hardened-off plants (May/June)
Harvest
July–October
Likes
Fertile, well-drained soil, plant food and sun (a south-facing wall is perfect), regular light watering (to prevent splitting of skin)
Dislikes
Shade, white fly (plant marigolds to deter them)
Varieties
Alicante, Green Zebra (green/yellow stripes). Cherry: Cherry Belle, Sungold (yellow), Gardener’s Delight. Hanging baskets: Tumbler or Pearl; mix historic varieties
Tips
Keep plants focused on fruit (not leaf ) production: pinch off non-flowering sideshoots and the top of plant when fruiting. Green tomatoes make excellent chutney
