Black spot on roses

Posted: 27/04/2013 at 12:49

Pentillie, Black spot is a fungus which affects the leaves and is transmitted by spores, so watering anything on the roots won't help.  All you can really do in addition to the things you have already mentioned is to more regularly spray the leaves and keep them really well fed.  On my clay soil, it doesn't matter what I do so just have to put up with it.  One rose "Peace" is about 40 years old and gets it really bad, but is still growing as strongly as ever.  If you see signs of black spot on the actual stems, cut them back really hard early next spring and it will lessen the effect for a couple of years.  Try and keep the roses as open in structure as possible - wine goblet shaped is recommended, as the more light and air that can get to the middle of the bushes, the better.

The JF might work if watered on roots of plants affected with vine weevils though.

Your top performing BLUE clematis

Posted: 27/04/2013 at 11:40

What shade of blue do you prefer, and what type (ie group1, 2 or 3?)  Many of the most reliable large flowered (gp2) types are on the purple side.

Are my grapevines dead?

Same here - seems they are well behind this year.

Can anyone tell me what this is plese...

It could be a Pulmonaria, which come in many many forms.  One variety is called "Ray Davison" which has light blue flowers which turn pink as they age and I do see some pink in your photo (although it's difficult to see clearly.)  Edit: It could equally well be one of the comfreys, too, as figrat says.

Broad beans

Posted: 26/04/2013 at 23:24

Hi SS, Broad beans are fully hardy and some varieties can be planted in the autumn and will survive everything the winter can throw at them.  Do 'harden them off' before planting out though by putting the plants out during the day and bringing them in at night,  for about a week.  Good idea to protect them from the wind, especially when they get taller.

Good Evening FORKERS

Booked a day's holiday today and got a lot done in the garden, but ran out of 3" pots while potting things on and had to waste an hour going out to buy more.  Couldn't resist the 2-for-a-fiver offer on clematis while I was there though!  Proper April weather here too - showers, sun, hail, sun etc.  Had 24x70l bags of compost and a dozen 80l bags of bark to shift too, but as it was supposed to be a holiday I've left that until tomorrow..  Plan is to get the spuds in this weekend, too..  Work on Monday will probably seem more like a holiday than my 3 days off!

Encouraging bats in our gardens

Posted: 26/04/2013 at 21:35

I'm lucky enough to have at least 2 species of bats visiting each year.  I think one species is Noctule as they are large and I can actually hear them (sounds like 'clicking') but not sure about the others.  I enjoy sitting out on a warm night just after sunset and watching them flitting around catching insects in the fading light.  It's quite amazing how agile they are in the air! 

fruit trees

Posted: 26/04/2013 at 21:13

Hi Tel, hope you're OK.  Yes, if you can't get them in the ground, then feed them in the pots.  The easiest thing to use is tomato fertiliser, mixed with water as advised on the label.  Tomato fertiliser is a good general purpose feed for fruit trees and other fruting plants.

Like Fairygirl, I usually pot-on to 5 or 6" pots after the 3".  I don't plant into the cold greenhouse until local night time temperatures are guaranteed to not drop much below 10C, so about the end of May.  They've spent most of this week in the GH all day and night, but will be brought back indoors each night starting tonight, now that the night temps are forecast to be single figures (or even frosts) for the next few days.
