Like most other govt agencies Bot Gdns have been through a pretty rough patch for the last 10 yrs at least. Funding cuts are now called 'required efficiencies' and staff levels have dropped significantly. In our local BG a wisteria tunnel took one skilled gardener two weeks to prune properly............ now it isn't done at all except to slash back growth that is an OHSW risk, or gets in the way of the mechanised 'Gators used by the staff to get around. Once the ratio of gardeners to administrators was about 7:1 now its the other way around: there are more administrators than hands-on gardeners. BG's have also been reviewed endlessly and been obliged to redefine their key role; thus they are now strictly scientific organisations, the rest & recreation/ public education roles have largely been ditched. Thus in our BG there are no major collections of decorative plants apart from native plants: the rest - exotics - have been disbanded, dispersed or destroyed - bromeliads, orchids, ferns, succulents, cacti, begonias, palms, perennials and so on. The heat in the biggest greenhouse was turned off two years ago! All those growing skills and plant knowledge lost. Economic rationalism and Baroness Thatcher have much to answer for.
