Tiny orange/red eggs on compost in greenhouse

Difficult to see but I think it's a fungus, so I would discard that pot in case it spreads.

Welcome to the forum BTW

 

I've seen that before on those horrid peat pots that you get - sure, they may well dissolve eventually, but they always seem to come with tons of spores/fungus free of charge.

Welcome aboard

EDIT - and a closer look at the photo suggests your seedlings are indeed in those peat pots. As soon as you can, I would pot them on into a conventional pot

 

I tried those pots the first couple of years when I was a beginner, and had nothing but fungus and mushrooms from them - I give them a miss now.

I can recommend a pot supplier if it helps, but they sell in moderate to large quantities. Some garden centres have pot repositories where people can put their unwanted pots, and other can help themselves - might be worth a look for you?

Whereabouts are you? UK I presume?

PS - I found that plastic cups (the sort you buy in the supermarket for parties) with a few wee drainage holes in them were a better option than the peat pots - they are only a short term solution though, especially with tomatoes as they really get going once they are up.

Feel free to ask whatever you need to - we were all beginners once, and we are all here to help each other (and have a bit of a giggle too). If you need any help using or navigating the forums, ask any of the regulars (you will soon spot them), or give one of the staff team a shout.

 

Ah, your location explains a lot - - my mum lives just outside Musselburgh, so I am reasonably familiar with the Edinburgh area. I reckon you will be two to three weeks behind the south of the country in terms of weather and temperature, so once things warm up a wee bit your tomatoes should be off and running.

If you are really keen, you could get yourself some heat in the greenhouse (I use an oil filled radiator that is controlled by a thermostatic plug - seems to work well), but given that we are well into May, that is probably going to be overkill for the sake of a week or two.

First things first, get them potted on into nice fresh pots - sink the seedlings as much as you can so the top of the compost is just under the seed leaves (cotyledons), and what is stem now will form root quite rapidly. Once you get the first set of true leaves, you will have stocky wee tomato plants in a couple of weeks, and you can then feed them a bit to help things along.

I usually get my pots from Garden Superstore, as they are cheap as chips, and last really quite well (I am on my third year of using the wee pots that are 8p each or less, and they are still fine - just store them in the shed once you are done with them for the year).

For trays, in addition to the above, I also sometimes use Scotplants Direct - - I got a load of 12-cell trays from them a few years ago and they are really decent quality for pennies.

Where you are, one of the biggest challenges is going to be temperature (or lack thereof) - and of course wind scorch if things are outside in that cold wind that blows in from the firth; once you get a good warm spell, or if you have a bit of shelter at your location, you should do fine.

Nice to have your company, and I look forward to nattering away with you.

PS - you did the right thing posting photos, as we love photos around here, and they often help others to help you.

 

You are more than welcome - you don't have to spend a fortune really, as long as you make it safe and have complete control of how things are laid out (as in, not a shared garden or anything).

I use similar to these:

Heater

RCD

Thermostatic socket

Extension lead

From the mains socket indoors - RCD first, then extension lead out to the greenhouse, then thermostatic socket plugged into that (extension fully unwound by the way), and then the heater. My extension leaves the greenhouse via one of the roof vents (sellotape a bag or some bubble wrap over the inside if it is letting too much cold air in), and then goes in through our utility room window to the mains socket.

Good luck

 

Pretty much - mine went out in March time then will come in when the heat is no longer needed. At the moment, it is mostly there for the radio since it has warmed up, but its good to have the thermostat to kick the heating in if the overnight temperature drops (which it is due to tonight). You don't want it out too early, as you will spend a fortune heating a greenhouse if you are not careful.

You can also insulate the inside of the greenhouse by sticking clear bubblewrap (get it as a big roll from the likes of Amazon) to the inside of the glass - helps keep the heating bills down a bit. Where you are, I would say there is little point in kicking anything off before the third or fourth week in March at the earliest
