The answer to 'best time for hedge' is that the best time to trim and maintain hedges is typically in late winter or early spring, before new growth appears. This is the ideal time because the plants are dormant, which minimizes stress and allows them to recover more easily from pruning. Additionally, trimming in the spring encourages new, healthy growth throughout the growing season.
It's important to avoid trimming hedges during the hottest summer months, as this can damage the plants and cause them to become stressed. Pruning in the fall is also not recommended, as it can leave the hedge vulnerable to winter weather and potential damage.
