Lettuce 'Suzan', Organic

Butterhead Lettuce. Summer Lettuce variety

Availability: In stock

Packet Size:1 gram
Average Seed Count:900 Seeds


This famous Dutch lettuce variety arrived during the 60's and instantly became a growers favourite. Today its lovely, large yet compact, pale green well formed heads are still in demand. Lettuce 'Suzan' is a traditional, large-framed, green butterhead. The heads are tightly-packed and the hearts are fleshy and tasty.

Lettuce 'Suzan' holds well in warmer temperatures without bolting so there is a long window of opportunity for harvesting.
Often referred to as a 'Summer Lettuce variety', the seeds can sown as early as February and successional sowings can be made throughout the summer. It is the perfect variety for early sowings and for crops grown under cold frames, it can then be grown throughout the whole summer outdoors, making it a good all rounder.

This very reliable variety is very easy to grow, in the smallest of gardens, in growbags or containers. It can even be grown in pots on a balcony or patio.
For the best lettuce experience, pick early in the morning and refrigerate for eating the same day.

  • Organic Seed.
    This seed has been organically produced. The seed has been harvested from plants that have themselves been grown to recognised organic standards, without the use of chemicals. No treatments have been used, either before or after harvest and the seed is supplied in its natural state. It has been certified and is labelled with the Organic symbol.

Prepare the site:
Lettuce doesn't do well in very acidic soils, and some say the pH shouldn't be lower than 6.5. A rich soil is excellent for lettuce, but the crop will also do well in average garden soil. The best crops are grown in soil that is deeply enriched with well-rotted manure and is well-fertilized before planting, especially with high nitrogen--leaf-stimulating--fertilizers such as 10-8-4, cottonseed meal, or blood meal.

Timing: Sow in February to July for transplanting March to August and harvested May to October
The perfect temperature for germination is 4 to 16°C (40 to 60°F) rates decline above 20°C (68°F). The perfect temperature for growth is 16 to 18°C (60 to 65°F)
For the best crops, sow in succession from spring to late-summer. The butterhead lettuces will be ready to crop around 72 days after sowing. They are more dry tolerant than most salad leaf vegetables.

Sow at a seed depth of 6 to 12mm (¼ to ½in) Seed will germinate in 7 to 14 days.
Sow seeds in short rows about 30cm (12in) apart. To do this, make a shallow trench with a cane about 15mm (¾ in) deep. Space the rows 20cm (8in) apart. Tip a small amount of seed into your hand, take a pinch and spread thinly along the trench. Cover with soil, label and water. If birds are a problem in your garden, spread netting to prevent them eating the seed.
When the seedlings are about 2cm (1in) tall, thin them out to give them space to grow, 15 to 20cm (6 to 8in). Make successional sowings at 14 day intervals.
On a hot day, water the soil thoroughly before sowing. Try, if possible, to sow during the early afternoon.

A mulch of grass clippings, salt hay, clean straw, or the like, will keep the weeds out and the growing soil moist and cool. Watering is essential if rainfall is scant. The plants need almost constantly moist ground. This is particularly important when the lettuces are one or two weeks away from harvesting, as dry soil now will cause the plants to put their energy into producing flowers.
The key to tender and tasty lettuce is rapid growth, however lettuce has a relatively shallow and compact root system that doesn't absorb nutrients and moisture from the soil very efficiently, which can slow the growth. To encourage fast growth, add plenty of finished compost before planting and again as a side-dressing a week or so after seedlings appear or transplants are planted. Give supplemental feedings of compost tea every few weeks until harvest.

Aphids – Wash off minor infestations before the plants are eaten. If there is a heavy population grow nasturtiums near the lettuce, or use an organic solution.

Harvest from the end of April through to October - 72 days to maturity. The butterhead's are not a regimented, orderly lettuce: each will have its own unique appearance and character. When the head of the lettuce is firm when gently pressed it is ready to harvest.

Rotation considerations:
Avoid following radicchio, endive, escarole or artichoke.

Good Companions:
All brassicas (except broccoli, but especially radishes), beat, carrot, cucumber, onion family, pole lima bean, strawberry
