The Size of a Pea Plant

Pea plant varieties grow to different sizes.

Many gardeners grow peas in their spring vegetable gardens. They provide several vitamins and minerals, and can go in a variety of dishes. The size of a pea plant depends on the pea variety and the plant's staking methods.

Types

Pea plants generally grow either as bushes or vines. Bush peas usually grow to heights of 2 or 3 feet, while vine peas can reach up to 5 feet tall.

Considerations

Several factors affect the size of pea plants. The University of Minnesota Extension warns that pea plants usually stop growing in temperatures above 85 F, so gardeners may not get their pea plants to reach full height if they plant them late in the spring too close to hot summer temperatures. A relatively neutral soil pH, good soil drainage and generous watering during dry weather also help pea plants reach their maximum sizes.

Support System

Climbing vine peas grow tallest with stakes or trellises to support them. With proper support, large varieties of climbing vine peas can reach up to 5 feet tall. Small bush varieties do not require supports, although stakes will help them grow more vertically in closely planted rows.
