Hi, I have a new dwarf apple tree, that I planted last year. It seemed to be doing fine, then around the end of Aug. it's leaves turned brown and it appeared to have died. When I called the garden centre they said it may have gotten sick, and to put dormant spray on it in the spring and it might come back. So my question is when should I put the spray on?

In Zone 5 I would apply it as soon as convenient after May 1; in any case before buds start breaking into leaf. A warm windless day would be ideal; anything close to it is OK too.

Would it be possible to start seeds inside and when? I have windows on the east side that give a lot of sun in the morning till about 2pm Also I would like to cut my Geraniums back as they are getting leggy. Could I put the cutting in soil to start new plants?, and what soil do I use?

Carol, when you buy the dormant oil spray, it will give you instructions. Try to get the kit that also has the lime sulphur, and that way you get the fungi, molds, and the overwintering insect eggs.

Thanks for the information, I will get the kit and apply after May first. Carol

I have another thought, should I apply this dormant spray to my other trees. I have a dwarf cherry, that I planted at the same time as the apple, and I got a couple of cedar trees 4-5 feet, that someone didn't want, last fall, we dug them up and replanted them. Would it help them to have dormant spray? Carol

Carol. The Cherry is a good candidate for dormant spray if you had fungus or insect problems last year. The cedar NO! When you buy the spray read the instructions. There are several insects and fungl problems it controls on certain trees. They will be listed. It is not a cure-all for every type of tree. As a matter of fact it could damage some trees if not applied correctly. Interesting to note if you grow roses and have had lots of problems it works great to control fungus and aphids before they become a problem. Only apply to woody stems not green soft ones. As a good rule of thumb, apply on a day the temperature is above freezing, early enough so it dries before nightfall. It must be applied before any sign of buds opening(leaf or flower). Depending on your zone it could be mid April to May. Hope this helps

Pat. I have used dormant spray on fruit trees but not on rose bushes. I Have had a serious powdery mildew problem on my rose bushes for a couple of years now. I am guessing that the lime sulphur would be the best to deal with mildew. My understanding is that the strength of dormat oil is that it coats and kills overwintering insect eggs. Greg

I did have problems with my roses last year (black spots, and little green bugs), and my lilac didn't look too great either(whilty looking leaves). All of these were planted last season, as I live in a new development. Could the problem be related? My dwarf apple, lilac and roses? The dwarf cherry did ok.(I think?...I guess we'll see this year) I didn't realize it would be so hard to get plants to grow happy and healthy. I hope I have better luck for their second season.

Yes Greg the lime sulphur part of the dormant spray works on the fungus and the oil portion acts to smother any eggs or overwintering insects on the plants. They work good incombination not only for the double control but I think the oil my help the lime sulphur stick better. If you clean up all the dropped leaves of your roses as well as try the dormant spray that should get you off to a good start. However watch for signs of powdery mildew returning, remove any infected leaves and treat with a fungicide. The only way to control is to stay on top of it. If your area is very humid make sure you do not water on the rose leaves and certainly do not water at night. Damp foliage is more suseptible to mildew. Carol that goes for black spot too. As for your lilac, wilting leaves in the first season of planting most likely is just stress. Black spot does not affect lilacs. You may want to give everything you planted last season a boost with a root promoting fertilizer something high in phosphorus with a rooting hormone in the formula is my preference. You can do that as soon as things start to green up in your area. For me that may be not until late April :-( For you? But remeber Carol in the second season plants always seem to find their legs (or roots in this case) and your plants should perform better for you. Good Gardening to both of you, I'm off to shovel another couple of cms of snow that fell since I shoveled this morning.

Thanks Pat.

Unfortunately, I have a very shady yard and my roses are in the sunniest spot, which I think is just enough for them to flower. Most of my garden is shady and damp. Not ideal for controlling mildew. Not much I can do about it though short of taking a chainsaw to my neighbours trees (joke). Thanks for the tip about the leaves. I should know that, but it helps to get reminded.

Carol. Re your comment on black spots on lilac. In my previous garden, I got wilted leaves with black spots on my lilac the first year after planting. It was fine the next year. It sounds plausible that it could be planting stress as Pat suggested.

Yahoo, it's finally spring(ish)!

Karen, I use the temperature requirements on the package as a guide. But I think it also mentions something about when the buds look a certain way - just before leafing out. That's the measure I use.
