Lime sulphur - another aspect

| I am planning to spray LS in my Blue Mountains garden because the BS was particularly bad in the season just past. However, the received wisdom is that one should only spray when the roses are leafless because the LS would kill new shoots and leaves. So where does this leave the perennials growing under the roses? Will the lime sulphur kill them? |

| Meryl, I've only used lime sulphur for the last couple of years, but my experience has been that it only damages the foliage but doesn't kill the new shoots. It's a bit difficult to tell at this time of the year whether it damages the perennials as they have either died down or been cut back, but I haven't had any deaths. I can say with certainty that it doesn't kill the weeds, so probably if you're careful, and maybe lift any perennials you're worried about, you should be able to spray with confidence. I'll be interested to read what others who have used LS for longer than I have have to say, as I too will be pruning and spraying in the next few weeks. |

I just sprayed with LS and covered the perenials with some newspaper to protect them..First time I have done that .I sprayed very gently between them to get to the ground and kill the spores etc.
All ok so far.

| Hi Meryl2, Lime sulphur should be OK as long as you avoid the heat of the day. I have just sprayed my roses (see reply to wattleblossom) last weekend and they are all in new shoots and some have quite a lot of leaf and they were OK. I wait till late in the day. I have bedding begonias around the roses and they seemed unaffected by the LS spray.I only use LS at this time after pruning and believe it does make a difference to the dreaded BS starting off the year with a clean slate. |

| Lime sulphur can be sprayed any time of year at low concentrations for mildew and mites (if you can put up with the smell!) At winter temperatures it won't harm new growth in my experience. And Meryl, in the chilly Blue Mountains I don't think your roses will notice at all! |

| Good idea with the newspaper Michelle! I've found it doesn't HURT other plants, but it can leave a white dotty film over the leaves, which looks pretty poor especially on my gardenias. |

| Excuse my ignorance but I heard something about lime being good for black spot so I bought a bag of lime. Is this the wrong thing ? Do I have to get sulphur added ? Or is it already lime sulphur ? |
RE: Lime sulphur - another aspect

| To answer the question re lime . The bag of lime is different to lime sulphur. Lime Sulphur is a liquid fungicide while lime is a soil conditioner, used to raise the ph level. Two entirely different products. Did you ask for lime or lime sulphur when you made your purchase ? |
