Grey Mould Attacks!

I'm growing three BigBud plants in pots outdoors here in the UK.
Two of my plants have a covering of grey mould near the bottom of the plants where branches join the main stem. This has caused one (smaller) branch to begin wilting. I know the mould thrives in humid conditions so maybe its the damp air here in the UK of late? The lower canopy does have air getting to it so I'm not sure what I can do really. I have read that sodium bicarbonate applied to the area can help- is that a good plan? My plants are not overwatered (only water them as the need it-before wilting).
I've done several grows and never had mould before. Thanks for any help!

Wish I could see a picture of the actual mold. Are these plants grown outdoors? How is the soil moisture? If you say that your plants aren't overwatered, and they live indoors, then chances are you don't have a mold. If they live outside, and it may have been raining frequently, then you might have a mold. Aslo, you may want to check for bugs. If you notice aphids and/or ants, you may have a sooty mold. Do you notice any mold on the leaves? Need more info and pictures would help greatly.

The mold problem sounds like "damp off". You can gently apply a rooting hormone like Rootone or Olivias. There are fungicide products for roses also that you may use. A Q-tip is a good applicator tool.

Um hello Bottesford.....
Are you there?
Have you seen the weather?
UK is currently inundated with massivley high humidity, especially in the south of england.
The whole weather is like 200 miles lower than it should be.
Ask michael fish.
;)

But yeah, humidity is a big problem, and it's too humid at the moment to leave them outdoors,

Thanks for the replies! Mole- yeah it is rather humid of late, but then it always is in the summer! Thankfully high pressure is taking over this weekend- so dry, sunny & warm at last!

The plants are grown outdoors on my patio. They do not come in at night as I ain't getting up at 4am to put them out when the sun comes up! I can see no bugs on them (well other than the odd fly the lands on them from time to time). The mould is confined to just the branch to stem joints. Leaves are fine. The green stem coating has been replaced with a dirty grey colour.
Soil moisture- I generally water them till they're soaked, then leave it till the soil becomes dry again. It has rained a fair bit here lately, but generally only light showers. I take the plants in during heavier rain.
Photos- I will be able to get some tomorrow which I shall post up on here.

keywestcathy- are these treatments likely to kill the mould to allow recovery, or simply stop the spread of mould?
