Salvias/Salvia Cuttings

I planted several different Salvias in a new border this year.  Unfortunately, I can only remember the name of one - Caradonna - but all are the bog standard, 40-60cm blue/purple flowered type.  Not my main question.. they've grown/flowered beautifully but slightly disappointed having read they'll flower from June to November.  I've been cutting back hard the spent flowers with little reappearance of new flowering shoots.  

I've not much experience of cuttings.  Am I correct in thinking I take them in August; do I use a gritty compost; do I take them from semi-ripe stems and, finally, leave them in a cold frame over winter or somewhere a bit more protected?

Thank you.

    That sounds right. This time of the year, most Salvias will take well to this type of propagating. Everyone has their methods. The general rule is light and free draining, so you could make that up with normal compost with sand, grit, small polestyrene balls etc. 

  • Thank you so much for that.. and apologies, I've not logged in for a while.

    I best hope they put on some growth then after the slightly more drastic chop I gave them!

    I'd just add that you should choose non-flowering shoots for cuttings. If there are any buds the cutting will put its efforts into producing flower/seed and not roots

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.
