I would like to naturalise daffodils in my garden - in western Sydney (hot summers, getting hotter, and fairly cold winters with occasional frosts). I have both Leucojum (snowflakes) and jonquils naturalised, but the daffs seem to flower once and are never seen again. Would appreciate any ideas!
Plant them deep. Try one and a half times recommended, then if they sitll vanish, double the depth recommended. Ensure the soil is nice and friable above them so they can push through at flowering time, and mulch heavily in summer.
Thank you - I have just seen your message. This years" are in and deeper than before, so I will have to wait and see. If this lot goes too, I will go for double depth.
I think in that area being hot summers you will need to lift them each spring & store them or buy new each year.
