mock orange

I have three Mock Orange plants, 2 in large pots and one planted in garden, had them for 4yrs, none have flowered, any ideas? 


  • Do you prune them? Do you feed them?

  • Pruned one to see if it would flower the following year, nothing, feed with tomato feed! cannot figure it out! !!

    do they look healthy and green and growing well? How big are they?

  • They are 4ft tall in the pots, the one planted in garden 5ft all looking healthy! !!

    They sound terribly small for 4 years old. I grew P. Katrina from a cutting takeb 2 years ago and that is over 6 feet tall already and good and bushy too. Had a few flowers this year and plenty of new growth for flowers next.

    To be honest I think they may well be too root constricted in a pot, they do better in the garden where the roots can sprad out.

  • There are shorter versions and taller versions 5ft might be the height yours grow to.

  • Thanks for input, will prune back, plant in garden, with feed. and wait .

    Why prune? It may well be that they do not flower because you ARE pruning. They flower on wood produced this year, so any pruning now is going to remove flowers.

    Mock Orange (Philadelphus) is a large shrub with exotically perfumed flowers in May or there abouts, depending where you live. It flowers on last years shoots and therefore if you prune it in late summer/autumn, you are removing those flowering shoots. Hence, no flowers the following year. Prune just AFTER flowering.

    They will grow to a hight of 8 feet or more in the ground if left unpruned and therefore your large pots are not large enough! even if pruned. Tomato feed will not make any difference to flowering especially if you have hut last years shoots off.

    Should be : Tomato feed will not make any difference to flowering especially if you have CUT (not hut!) last years shoots off.
