Growth—

Requires a well-drained moisture retentive soil[1, 2, 3]. Prefers a calcareous soil[3]. Prefers a pH in the range 6 to 7.5[4]. Prefers a rich loamy soil[1]. A light soil and a sheltered position is best for early sowings[1]. The sugar pea has a swollen, fibre-free and very sweet seedpod which is eaten whole when immature. There are several named varieties. This form is harder to grow for its mature seed, especially in damp climates, because the pod no longer has a cellulose membrane to protect the seed from damp and so the seed has a greater tendency to rot in wet weather. Peas are good growing companions for radishes, carrots, cucumbers, sweet corn, beans and turnips[5, 6, 7]. They are inhibited by alliums, gladiolus, fennel and strawberries growing nearby[5, 6, 7]. There is some evidence that if Chinese mustard (Brassica juncea) is grown as a green manure before sowing peas this will reduce the incidence of soil-borne root rots[8]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[4]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.

Propagation

Pre-soak the seed for 24 hours in warm water and then sow in situ in succession from early spring until early summer. A minimum temperature of 10°c is required for germination, which should take place in about 7 - 10 days. If you want to grow the peas to maturity then the seed needs to be sown by the middle of spring. You may need to protect the seed from the ravages of mice.
