I've been keeping track of the produce from the garden and like to sum it up at the end of the year to see how the garden is doing. First up is a plot of how the total amount of produce for the year has changed with time. I like this graph, it shows a few different things. The produce gets off to a slow start and start to pick up in spring but really accelerates around midsummer. Things slow down around October once the apples are picked. Comparing this year to previous years it is clear that 2015 has been the most productive so far. There has been about three times as much produce as past years, with the exception of 2011 which had a major potato crop (I planted the whole front garden with potatoes to clear it). The bar plot above shows the change in total amount of produce which reinforces the point. But what difference has the polytunnel made? Is the increase just down to the extra vegetables from there? The next plot shows the total produce without the vegetables. This plot makes it pretty clear that it's not all down to the polytunnel. The rest of the garden has had a really good year too. This one shows the monthly productivity over the last six years. It has definitely been a good year for fruit. This next one shows the break down by type of produce. There are some vegetables in April and May, some from outside and some from the polytunnel. The soft fruit picks up in June then peaks in July. The tree fruit starts in July with early apples from the Redsleeves tree, some through August then a peak in September. Vegetables really take off in August, September and October with tomatoes, cucumbers and courgettes. Details up to the end of September are in the bar on the right (more coming later). I'm pleased to see how this has spread out more compared to last year. The maturing trees and the polytunnel are extending the season. I'm sure I could up the productivity earlier in the year with some more effort, but not sure if the time required fits in with a low maintenance approach. Last graph. This one shows how the soft fruit and tree fruit has done. The soft fruit has really taken off since 2013. 2015 was a good year with a great raspberry crop, more currants, jostaberries and gooseberries amongst others. The top fruit from the trees is starting to develop. One of the apple trees (Tydeman's Late Orange) tends to be biennial, but I think the weather has quite a lot to do with it. Of course the standard trees are still growing so are getting more productive. The grafted apple tree is starting to bear fruit now too. I'm not sure what the final amount will be but I can imagine it will be two or three times the total mass when the trees are fully grown in a good year.
Interested in how productive the garden is per unit area I came up with a figure of 7.24 ton/ha. I've found it hard to come up with good numbers to compare this with, but I've seen 31 - 40 ton/ha quoted for high intensity allotment growing so the garden is less productive than an allotment, but then it is much lower maintenance too. I've also got some numbers for agricultural production at around 3.7 - 7.8 ton/ha so it's near the top end of that. As AnniKelsey pointed out in her blog recently, it's not just how productive you are per unit area, but how productive you are per person. On that basis I'm very pleased with the garden this year. Thinking a little more broadly about the role for forest gardens and the type of produce they can yield, I'm starting to think that they make a lot of sense as a low-maintenance use for back gardens and public spaces. They can complement higher intensity allotment and other forms of growing to provide a diverse range of local food as well as their myriad of other benefits, not least the aesthetic ones. Hopefully these productivity figures add a little weight to that argument. I'm going to keep on recording and see what next year brings.

You've been busy with the graphs :)

Thanks Andy, yes I like doing the graphs! No I haven't been keeping a record of time that I spend, but it isn't that much. It is spread out over weekends and in the evenings in the summer. It's pretty much just me. I'm the same. In the winter I might go a week or more without going out in the garden. Perhaps 20 min to water part of the polytunnel. I will do a few jobs like pruning in the winter. In the summer is the biggest draw on my time with harvesting. When the soft fruit is in season I will spend 15 min most evenings picking sometimes with the kids helping. But the garden does look after itself pretty much. I water the blueberries in pots and some of the polytunnel but that;s it. I would guess on average over the whole year about 3 hours a week.
