Disease resistant roses

Posted: 28/07/2014 at 20:31

Fluffy I only grow english roses from David Austin they are without doubt resistant. Over the years I've tried many and like you got frustrated with black spot especially. After much experimentation, I have finally found a good way of keeping black spot under control, and I use it in other gardens for people who I garden for. I have found it works. 

No matter what the rose, remove and burn the affected leaves, even if it means you have just bare stems and no blooms. Clear the ground around the rose, no detritus or dead leaves. Water well and feed. Then spray/soak with fungicide, rose clear is as good as any, and spray the ground around the rose as well. You can then mulch and make sure you have good air movement around the rose. I have never read or seen anyone recommend spraying the ground around the rose, but common sense dictated that the spores that cause black spot fall to the ground and rain falling makes them rise and re infect the rose. 

It works for me and my customers, it may seem brutal to strip the rose bare, but they produce new growth within a few weeks, and it's usually healthy.

If you get a further infection just follow the same process. I can honestly say, I haven't had a failure yet.

There are so many beautiful roses, I wish I had room for more, confining yourself to one type is a matter of choice and one I made for more than one reason, but I'd hate to see anyone who can grow whatever is their choice.

Honeysuckle mildew problem

Posted: 28/07/2014 at 17:12

There's never any need to spray honeysuckle against mildew. Just keep the roots soaked, mulched and fed, it's a tough plant and will recover on its own even from a black spot infection which sometimes follows the powdery mildew. If you have real trouble then prune it back hard in spring, mulch and keep the roots moist, spraying is a waste of time and money.

Ivy plants

Welcome Lorna, ivy roots do die after treatment but it takes time and patience usually longer than for the foliage to die down. The roots don't break as easily as bindweed, they're tougher, but hard to get rid of. I'd dig out what you can, then treat anything that comes up afterwards. With any weedkiller it has to be sprayed on greenery, spraying roots won't work. Be patient and vigilant and you will get rid of it eventually.

Wood charcoal ash

Yes and no greg4, I'd burn it first, without the use of any lighter fluid, then the ash can be spread on your beds.

Cheryl, any proprietry weed and feed will be ok, even the cheaper ones will do the job, follow the directions on the box or bottle. As for a rotovater, I'd be more inclined to hand dig as any perennial weeds left alive will be chopped up and grow again. Hand digging although hard work is the best method. Afterwards you can spray anything left as it comes up.

I'd plant them together Eileen, they do spread once established although it can take some time for them to do so.

Curing my hedge? - Dying in parts

Posted: 26/07/2014 at 22:32

Robert, from your picture the hedge is too wide at the top, it should be wider at the bottom, it's also quite heavily shaded by the Pieris and the rhododendron to the left of the path. It needs light at the base and if you cut the hedge as in the picture you are cutting too deeply. Privet should be trimmed lightly regularly every 2 months during the growing season. Light at the base will encourage new shoots, and if it's like the picture, mulch to a depth of 6 inches around the base of the hedge as well, you'll get new growth if you do. The alternative is to cut it down to a foot high and let it regrow.
