Not put anything in yet- the temptation is easy to resist as I'm still in the Middle East and moving back permanently to the UK next weekend after 18 years away (yay!).
In January, I managed to get a quarter plot in the UK which I weeded, put compost on and covered over with membrane in the freezing weather at the end of February, the soil was not frozen- just very cold. I have a ton of seeds waiting, potatoes chitting away, onion sets, shallot sets and garlic ready to go in when i return (straight away for the garlic, will hold back until Easter for the onions, shallots and spuds). I'm going to be busy!
As to the plot here, the perpetual spinach, turnips, herbs and tomatoes did great in the past few months. I managed to overcome the extremely sandy soil by dosing up with Agroleaf soluble fertilizer on a regular basis which was pretty much all I had on hand.
