"my 3yr old crab apple tree is covered in these eggs but no eggs on other fruit trees By steve marie2"

Hi Steve, those are not eggs, but some kind of aphid.  There's some RHS advice on aphids here:

http://apps.rhs.org.uk/advicesearch/profile.aspx?pid=181

As the tree is probably still quite small, you can probably kill the aphids by spraying with water containing a small amount of washing-up liquid (this will drown them.)  Or use a proprietry insecticide which says it kills aphids on the label, if you prefer.

Have a look to see if there are any ants running about the tree.  Ants 'farm' aphids and feed off the sugary liquid they exude. The ants carry the aphids around the tree to fresh new growth.  If you put a thick ring of vaseline or similar all the way around the trunk of the tree, it should stop the ants climbing up and doing this.

Talkback: How to grow dahlias from seed

What sort of dahlias are they, Natasha?

Can anybody identify these?

Hi Stu, Fruit trees on dwarf rootstock are always a good bet.  You get blossom in spring, fruit in Autumn and they won't grow too large.  These are the rootstocks to look for if you decide to buy any fruit trees:

The jungle in my garden needs to go.

Looks like it's overrun by brambles, a very tough thing to deal with.  You can either cut them back to about a foot long, then completely dig out the roots, or use a very strong weedkiller, like SBK Brushwood Killer.  I'd advise the latter unless you have a few weeks to spare to properly dig everything out.

If the ones with the rounded leaves are slightly furry, they could be foxgloves.

Yeah, it's particularly tricky this year, Bf!  I delayed sowing seeds until Good Friday this year but they're now ready to go into their final planting positions.  I have a cold greenhouse but it's still getting too cold at night to put them in there really.  It got down to 3.2C the other night, which is low enough to have checked their growth.

One good thing about keeping them in small pots for a while yet is that they will likely start to produce flowers - in fact I just looked and some of mine are showing the beginnings of flower clusters.  They will soon romp away once finally planted.

Do the brown/back spots have yellow rings around them?

Clematis problem

Posted: 11/05/2013 at 19:06

This is not unusual for newly planted clematis, especially if the plants were originally bought in small pots/large plugs.  The thing to remember with all new clematis (of any group) is to cut them back to about a foot (30cm) from the ground early in spring (usually end of Feb or early Mar), the year after planting.  That will encourage them to bush out and send up new shoots from below ground.  As others have said, it's always best to plant them 4-6" (10-15cm) deeper than the original soil level in the pot to encourage them to develop a 'root crown', from which they can send up more shoots.  It also protects the roots of large flowered varieties from being killed if they get clematis wilt.

Wait until temperatures at night are guaranteed to not fall below 10C, so probably the end of May or early June.  Ideally you want them well developed before putting outside - say a foot (30cm) or so.  They will benefit from some protection from wind and rain if you can manage it and definitely need to be placed somewhere which gets full sun in order to do well.  Not that many varieties are really suitable for outdoors in the UK though - what type are you growing?

The daftest thing you've done in your garden

Posted: 11/05/2013 at 09:22

When I first moved here there was a fairly attractive (single) plant which I thought the previous owner had grown, so left it to see what it was.  Lovely tall purple flower spikes followed so I collected seed and spread it around a bit.

I've been pulling-up examples of my self-induced purple toadflax invasion from my borders for the last 30 years.
