There seems a lot of it about right now Bob 

Yes, I wonder if the rubbish weather most of us have had (not you Cornish lot of course!) has something to do with it?

looking for help.

Probably not Jo, as they usually die quite quickly..  The finger test is definitive.  Looks like poor light and lack of feeding to me and I would re-pot it.

Painting tanalised timber

I did the same in my shed using white emulsion LG.  The staining does seep through but, like you say, not an issue in a shed!   It's still standing 25 years later so clearly no problem regarding the effect on the tanalising!  I clad the walls of the shed out of cheap wickes feather edge fencing boards, so just goes to show how long those can last when protected by a roof.

It's a Dracaena, Todd.  The most common issue with them is over-watering.  You don't need to water them until the top 2 inches of compost is bone-dry (stick you finger in to test.)  They also don't like direct sunlight, but do need a reasonable amount of natural light.  Feed then with something like Baby Bio plant food mixed according to instructions every fortnight during spring and summer.  They also need re-potting into fresh multi-purpose compost every 2 to 3 years.

If you think over-watering could be the issue, don't water it now until the compost dries out and re-pot it in spring.  You can cut it back at that point and new growth will come from the cut stems, but it does take several weeks before you see the first signs of buds forming on the bare stems.  The bits of stem you cut off can be potted-up to make new plants.

I had one about 6 feet tall and cut it back as described earlier this year.  This is it now with 2 of the babies:

Yes, really annoying when that locking catch keeps engaging by itself!  I removed the screw and put a small extra washer on it before replacing so it now much stiffer and stays in the unlocked position while I'm using them.

Sounds like crown gall, a bacterial disease:

I would advise disposing of it and the soil from that pot too.


Recommend a good bird food?

Jo, yes it's fine in ordinary seed feeders, causes no blockages.

After trying many, many types over the years, I've settled on Johnston and Jeff's "Premium Wild Bird Food Wheat-free with Suet" which everything seems to like and is also husk-free so absolutely no mess.  There is nothing at all left when the feeders are empty and I mean nothing!

Contents from the label: PREMIUM WILD BIRD FOOD A high energy husk-free mix with no wheat, enhanced with suet pellets. Canary Seed, Natural Groats, Milo, Millet, Wild Seeds, Suet Pellets, Sunflower Hearts, Sorghum, Rapeseed, Peanut Nibs, Aniseed.

Greenhouse heating

I think SG is about right Yviestevie, they can tend to turn off a bit too quickly because of the warmer air nearby recirculating.  A thermostat is better as you can place it further away.  I have a heated bench made with soil warming cable and a thermostat which keeps the roots at a set temperature and that seems to work well, especially with a bit of fleece draped over the pots.  I don't have that many really tender things to keep going over winter though.

John, you can buy inexpensive greenhouse fan heaters which have a thermostat built-in.  They are splash-proof and many have a 'frost' setting so they only come on enough to keep the temperature above zero.

If you want something more sophisticated with more precise control over temperature, then have a look here:
