I have six Blueberry plants now, all in pots ranged round the edge of the patio. Two of them are very small still, not big enough to produce fruit this year. All six of them are "freebies" in that they all came from offers in magazines whereby you pay only the postage - which works out at about £3.99 per plant or something like that.
I have also been making an "investment" in my garden of a different nature. I have been adding some really special compost to my raised beds. It is composted stable manure, supplied to me by a firm in nearby Woking. This is good stuff, I know. I have used it before with excellent results. Over the last couple of years my crops have been a little under-par, in my view, lacking in vigour, so I thought it was time to re-vitalise the soil. Maybe my home-made compost is not sufficiently nutritious after all...
Yes, I know that to 99% of the population that photo is dull and boring, but to us gardeners it is not! It shows the greyish old soil being augmented by the new brown stable manure compost.
In due course the bed pictured and its peers will play host to my Winter veg, such as these Brussels Sprouts:
