I have decided to plant out my broad beans, even though the onset of winter is nigh. Planted in cells on 24 October the intention was to plant them out in spring. But they prospered in the cold greenhouse and developed roots which were bursting out of their cells. Following the guide that plants shout be transplanted once the roots appear through the holes at the bottom I accepted that they were too far advanced to be kept in their cells. Fortunately I have been experimenting with a fleece tunnel at the plot and so have constructed a sheltered home for them:
Here is the current state of play with my cut and come again autumn sowings. Set in the (unheated) greenhouse I have half trays of "Nice and Spicey"(N&S) to the rear and "Speedy Mixed" (SM) in the front. The earliest sowing was 19th August followed by 8th September and both of these have been harvested once. I think the slugs had a nibble of the earliest sowing when it was still outdoors, so there isn't much "come again" about that one. The 26th September sowing of N&S and the 7th October of SM are currently harvestable as Macrogreens whereas the SM sown 27th October could only qualify as Micro, still being at the cotyledon stage of leaf development.
In fact they are pretty much the same as my most recent indoor sown rocket microgreens,
Microgreen Rocket at 10 days old
To date I have yet to get a second harvest off any of the Cut and Come Again sowings. 8th September is nearly there but all growth is in abeyance now that the temperature has dropped. I might squeeze it onto the kitchen windowsill for a week or so before cutting!
On the left, cut and coming on again - 3 week later sowing on the right just about big enough to harvest for the first time.
So I have been having fun experimenting how far in the year I can push the cut and come again salad cold sowing. I think I have definitely reached the limit and both heat and light would be required between now and next spring.
And yes I still have some basil and coriander microgreens under lights. The coriander that has germinated (about half) is nice and tall but the basil is very low growing. No chance of getting scissors in there. I am beginning to see the advantages of mustard and cress!
I started out 4 weeks ago using a bespoke microgreen growing tray from Johnsons. Following the instructions scrupulously I sowed coriander and basil which, according to the packet, should be ready in 10-16 days and 16-21 days respectively. Well I am now 28 days in and it is time for some intervention. Progress has been painfully slow, and I make the following observations:
The design of the kit needs to be modified. What you get is a clear tray that holds a reservoir of water over which the growing trays are suspended. At first sight I thought the clear tray was a cover to retain moisture in the atmosphere above the seeds but no, it is the base and there is no lid. After the slow progress of three weeks I have enclosed the unit in a polythene bag to rectify this omission.
Also after three weeks I was having doubts about the design from the point of view of the growing medium. Spraying kitchen towel 2-3 times a day doesn't seem particularly onerous. Once you have been doing it for 21 days without fail you begin to wonder who is the mug! If you miss one session the kitchen towel soon dries out.
So after three weeks I took the third packet that came with the kit (Rocket - Ready in 16-21 days) and sprinkled it on the surface of a more conventional set up. A half sized seed tray with potting compost and a cover. This had the advantage of being moveable without the reservoir of water sloshing all over the place. I put this enclosed unit in an internal cupboard and forgot about it for 4 days. On first checking it looked like this:
so I removed it to the kitchen windowsill alongside the designer model. Given the time it has taken for germination of the first sowing I have to conclude that our kitchen is colder than your average kitchen. (Although it gets hot from cooking and the boiler is located in there too, there is no radiator so the temperature can drop.) I also have become convinced that there is a decided lack of sunlight.
Time to deploy the growlight setup in our (former) coal cellar. The tray can be heated but I haven't switched the heat on just yet. Now that germination has occurred I feel sure that the level of light is the crucial factor in producing green microgreens.
So, in conclusion, my purchase of the right kit for the right job turns out to be a bit foolhardy. It is less faff just to use the same system as I do for cut and come again salads but harvest them a bit sooner and pamper them a bit more with indoor temperatures and the supplement of some artificial light. No bother really but it has taken a bit of working out! To grow a seed needs adequate moisture warmth - and light.
It has been a good year for carrots. So much so that, despite chomping away on them as fast as rabbits, half the crop is still in the ground. So rather than moving the mountain I have revived an old idea with a new twist. Harvested root crops in the past have been stored in clamps: put in a pit, covered with straw and then earth, to protect from frost. Having the thrip netting in place already it occurred to me that, duvet style, the straw could float above the undug carrots for warmth. It is not going to blow away because the net is retaining it.
To recap we sowed a double tunnel of carrots this year, only lifting the netting for thinning and weeding on two occasions
By September it was clear they were growing away well
The netting kept off the root fly and the roots were happy just with the normal Edinburgh steady rainfall,
I have every hope that with this blanket of protection we will be eating our own carrots right up until next spring even if it turns cold and icy.
We have had three sub zero nights here in Edinburgh, so the outdoor gardening is severely curtailed.
Time to retreat to the kitchen (windowsill).
I bought this kit early in the year in a fit of online gardening enthusiasm but haven't deployed it until now.
It is simply a water tray with a drainage tray propped on top of it. The growing medium (a sheet of kitchen towel) you supply yourself!
Once the tray is filled with water and the paper wetted you sprinkle the supplied "microgreen seeds" on top and, using a water spray, keep them moist for two weeks....
The microgreen seeds I have selected are coriander and basil. Perhaps unsurprisingly they appear the same as my other coriander and basil seeds. There is a little voice at the back of my head that says. "Ah but these have been specially selected for microgreen growing and have no fungicide or insecticide treatment that garden seed might have been treated with" but I really do wonder if they are any different.
