A sunny spot protected from strong winds is essential.
The soil should be well drained and rich in humus, the more the better.
For an early start (late Mar) place a single seed edgeways 1/2 inch deep in seed compost in a 3 inch pot under cover. The critical part is temperature, these need at least 65 F continuous soil temperature, inc over-night (preferably more to maximise germination rates) until germinated.
Plant out to growing position only after all danger of frost has passed and soil has warmed.
Keep the soil moist, water copiously around the plants, not over them.
Keep weed free to allow air circulation.
Once the plants start to fruit, feed every 14 days with a tomato type fertilizer, these are greedy plants.
Keep harvesting frequently to encourage more flowers.
