bush
A woody plant distinguished from a tree by its multiple stems and lower height, being usually less than six metres tall; a horticultural rather than strictly botanical category.
bush: multi-stemmed woody plant under 6 metres tall
A bush is a woody plant that grows from multiple stems emerging near or at ground level, rather than from a single trunk like a tree. Height typically maxes out around 4 to 6 metres, though this boundary is conventional rather than rigid. In agricultural and horticultural contexts, the distinction matters because bushes occupy a different ecological and management niche than trees, and they respond differently to pruning, harvesting, and replanting.
Agricultural relevance centres on crop bushes: fruit-bearing species like raspberry, blackberry, blueberry, and currant are managed as bushes in commercial production. These plants fruit prolifically on multiple canes or stems, which can be selectively pruned or completely cut back depending on the variety and management system. Wine grape vines are also bush-trained in many regions, with the vine framework maintained at waist height or lower. Nut crops like hazelnuts are often grown in bush form rather than as single-trunk trees, easing mechanical harvesting.
Structural and mechanical advantages explain why farmers choose bush form. Multiple stems distribute the load of fruit or foliage more evenly, reducing wind damage and lodging risk. Bushes occupy less vertical space, making them easier to net, spray, or hand-harvest without tall equipment. They also regenerate readily if damaged or pruned hard, which is why traditional coppiced woodlands maintained bushes deliberately. In mechanised row crops, bushes fit the inter-row spacing and harvester clearance better than trees.
Bush form is not fixed: a raspberry plant can be trained as a single upright cane, a spreading multi-stem bush, or even a hedgerow. Pruning timing and severity reshape the plant's architecture. Summer-fruiting varieties typically retain two or three-year-old canes; autumn-fruiters are often cut to the ground annually. Neglected bushes become woody and unproductive; well-pruned specimens yield consistently. Some ornamental species classed as bushes, like privet or hawthorn, tolerate severe cutting and are used as hedges.
The term itself is imprecise because the botanical distinction between bush and small tree lies in branching pattern and stem count rather than hard height limits. A hazel or hawthorn specimen might grow to 8 metres as a single-stemmed tree or remain a 4-metre multi-stemmed bush depending on how it was managed from youth. In this sense, bush describes a form of growth and use as much as it describes a fixed plant type.
