Pruning Mock Orange - Philadelphus

known for their heady scent - especially on an early summer morning or
evening! Correct pruning is essential for this group of early summer flowering
Prune too early and you will lose the flower buds for the
current year. Prune too late and the shrub will not have enough time in
the growing season to provide flowering stems for the following year.
Don't panic - we are here with information and advice upon when and how
to prune your Philadelphus.
There are several Philadelphus - Mock Oranges - that need
regular annual pruning in order to flower well with a spectacular
display in early summer. We take you through the simple procedure

Most shrubs that flower at this time of
year (early summer - image taken 17th June) depend upon flowering stems
that were grown by the plant in the previous year (Growing season). If
you prune Philadelphus too late - late summer or autumn- fall - for
instance, then the shrub will not have enough time to make flowering
stems ready for the following year.
When and How to Prune Philadelphus - Mock Orange.
The secret of correct pruning is not
really a secret at all - You just need to know when and how to prune
your Mock Orange Tree.
As soon as the shrub had finished
flowering, cut out all of the stems which have just flowered. Prune them
back to around a third of their length. They will soon start to produce
new stems which will provide the flowering stems for next year. Do not
just prune little bits off the end. Prune right back into the bush.
Once that bit of pruning has been done,
then we (you) go on to the next stage of pruning. Pruning out around one
in three of all the old stems - but right back to near ground level. We
are talking about a few inches above the ground here.
The varieties of Mock Orange that can be
pruned in this way include ... Philadelphus Avalanche, P. Beauclerk, P.
Belle Etoile, P. coronarius Aureus - good hard pruning for this variety
to get that beautiful bright golden foliage - Philadelphus Innocence, P.
Lemoinei, P. maneau d'Hermine, P Mont Blanc and of course the double
flowered Philadelphus Virginal - sometimes called P. Virginalis. All other Philadelphus that flower at
this time should have pruning as above.
A great list of pure white flowers with
varying degrees of scent!
Reason for this pruning?
This hard pruning of old stems, will
prompt the shrub to send out new basal growths, which will provide good
flowering branch framework for subsequent years, resulting in a fresh
looking shrub. Do a further pruning of a third of old stems in
