grey mites on carrots, danger?

Posted: 25/07/2015 at 18:40

Aphids.  Try rubbing them off with your fingers and/or have a look around your garden for ladybirds on other plants and transfer them to the carrots.

Disappointing bread beans.

Sounds like poor pollination.  If there are few bees around when they are in flower not many beans will be produced in each pod, and completely unpollinated flowers will just fall off.  Not much you can do about it other than to try planting them at a different time next year or hope for a warmer spring.  Also try to grow bulbs and flowers which blossom from late winter onwards to help attract bees to the area.

What variety are they?

Spraying with water certainly helps prevent them getiing hold but once you have a heavy infestation I'm afraid to say that it is not very effective as it doesn't actually kill them.

Potatoes & Carrots

There's a great guide to the best potato varieties for various cooking methods here:

You just about have time to grow some carrots now - choose early varieties such as Nantes early, Napoli, Nelson and Mokum.

Try SB plant invigorator which sort of sticks them in place so they eventually die.  It also contains a foliar feed to help the plants grow.  The only thing I've found truly effective are spider mite predators (Phytoseilus.)  The suppliers of those often also recommend SB as an initial treatment before applying the predator mites.

Spider mites have evolved to be immune to most insecticides.

Why vegetable plants are getting yellow in color & not bearing fruits

Posted: 25/07/2015 at 15:26

The tomatoes don't look too bad although they are a bit small.  I would remove any dead and yellowing leaves as they will do more harm than good if left.  I suspect the fact that temperatures have been so up and down has put them back but there is still plenty of time left for them to set and ripen fruit.

As far as the gourd leaves go, they look like they are having the life sucked out of them by (I suspect) spider mites or possibly thrips.  Try using a magnifying glass to inspect the underside of the leaves (spider mites are too small to see with the naked eye) and look for webbing at the tips of the vines.  Spraying both the top and bottom of all of the leaves with SB plant invigorator may help if they are not too far gone.  Insecticides are usually useless as spider mite is generally immune to them.

Pamapas Grass

Posted: 25/07/2015 at 10:26

It will be hard work and you will need to wear protective clothing as pampas grass has extremely sharp edges.  It is also tricky to dispose of as it doesn't rot down quickly in a compost heap and will wrap itself around the internals of a shredder.

I had one with a metre diameter base right next to a fence.  I cut it down to the ground using a chainsaw and then treated any regrowth with a glyphosate based weedkiller.  It was dead in about a year.  The 'stump' was then dug out using a sharp spade, pick-axe, mattock, pruning saw and copious quantities of painkiller for my back.  It doesn't need any of the type of weedkiller which will poison your soil to stop regrowth - that's not a big problem with pampas grass.

If you are fit you should be able to do it yourself in the same way, if not, consider paying a professional to get rid of it for you including removing the roots using a stump grinder.  If you can afford to do that, get several quotations.  The same firms which remove hedges will be able to do it.

Good screening tree?

Looking at the angles of your neighbour's windows, they will not be able to see your garden unless they open them and stick their heads out, so I personally wouldn't be at all worried about being overlooked.

Potatoes with white specs

I've seen this before and it disappears when the soil on them dries.  I think it's a harmless soil fungus.  Or slug eggs..

Verbena growing, holes in leaves

Looks like flea beetle damage.  You could try a neem oil spray or (slightly less organic) pyrethrum-based spray which is made from a natural insecticide extracted from chrysanthemums.
