i missed this thread last weekend.
I also have a heated propagator which I have used once or twice, but I haven’t gained much from it, or I’m using it incorrectly. To the posters who use their heated propagators, do you just use individual little pots for your seeds in it, or do you put just compost in the base, put your seeds in, then use it as a mini raised bed if you see what I mean?
I used my heated propagator to crack open seeds. I sowed them in two half seed trays, in rows and as soon as they poke their heads up, they get pricked out and into small pots. I only use it during the first 3 months of the year.
I got rid of it when I switched greenhouses, the big one went to the allotment and I put a half size one in, next to a power source so moved to a heat mat. Again I used it to start seeds off and to keep the whole greenhouse warm, it gets switched off around the end of April. I freecycled the heated prop.
I can't offer any advice I'm afraid, total novice here. I have some questions though if people are happy to help? The soil on my plot is awful (see pic) - really difficult to dig, deep cracks, lots of bindweed and an area with matted, dead grass. My plan is to plant out some pumpkins, sweet peas and beans, and to also so some peas, beetroot and more beans, and maybe something for the winter (kale?). Will that work or have I left it too late? If I add manure can I plant through it? What would you do?
Looks like you are on clay?
So either you could dunk a load of manure on top of that, recover it and come back next year; you could cut a cross in the plastic, dig out the soil where you want to plant your stuff [a hole for each plant]], mix soil with well rotted manure, plant plant, fill back up with the soil/manure mix, water in and unfold the edges back up to the plant stem. Or save yourself 10 years of strife and start getting raised beds in now, building up as you go.
Our local topsoil place delivers and if you buy a truckload [3 tonnes] it costs about £180; but you usually get 4 tonnes [volume] of actual material. Esp if it hasn't rained recently.
If you dig clay now, the weed roots break and you will give them a new lease of life as soon as you take that plastic off.
