Prune spring flowering shrubs
This is a safe time to prune shrubs which have already flowered such as Spiraea, Choisya, Camellia, Deutzia, Philadelphus. Prune to reduce size, take out weedy branches, and to reduce leading shoots to make the shrub more bushy. Also prune at the bottom of the shrub where planted in a border to lift the canopy in order to allow more light and air for the plants growing around the shrub.
You can also prune Rhododendrons after flowering which maybe June or July depending on the variety. If the shrub has grown too big prune it back. It will look very bare and sorry but within 12 months will re-grow.
The shrub in the image left, had grown over a path and was cut back hard to bare wood in parts. The light green is the new growth has come back very strong and already covered the pruned area.
If you are renovating it is a good idea to do this over a period of 2-3 years cutting back a bit each year. If you are dead heading Rhododendrons, take care and do not remove the embryo buds behind.
Can be lifted, dried and stored now. For some bulbs, particularly tulips and hyacinths these really do prefer to be lifted to encourage them into flower next year, if there is time. Alternatively you can remove spent flowers from tubs and baskets and plant into the borders for next year, maybe they flower, maybe not, but you can then re plant the tubs with summer bedding. It is worth buying the slow release fertiliser tablets to put into tubs and baskets to keep feeding when time is short its one less job to do.
Spray regularly with organic pest control to keep aphids and pests at bay.
