Wisley is now a large and diverse garden covering 240 acres (971,000 m²). In addition to numerous formal and informal decorative gardens, several glasshouses and an extensive arboretum, it includes small scale “model gardens” which are intended to show visitors what they can achieve in their own gardens, and a trials field where new cultivars are assessed.

The laboratory, for both scientific research and training, was originally opened in 1907, but proved inadequate. It was expanded and its exterior was rebuilt during World War I. It was designated a Grade II Listed building in 1985.

Visitor numbers increased significantly from 5,250 in 1905, to 11,000 in 1908, 48,000 in the late 1920s, and 170,000 in 1957, and passed 400,000 in 1978, 500,000 in 1985, and 600,000 in 1987.

In April 2005 Alan Titchmarsh cut the turf to mark the start of construction of the Bicentenary Glasshouse. This major new feature covers three quarters of an acre (3,000 m²) and overlooks a new lake built at the same time. It is divided into three main planting zones representing desert, tropical and temperate climates. It was budgeted at £7.7 million and opened June 26, 2007.
