Drought and heat – thoughts about the future …

Once again, the weather has been a major preoccupation this month, and my thoughts on species future for the Sombrun Forest Garden Project have moved from the back of my mind to the front! As you will see from the monthly weather report below, most of the month has been dry and hot, and I think I have to accept now, given everything else that is happening with climate change as well, that this will become the norm. Not only have temperatures been higher than ever (40° and higher on three occasions already this year, two of which were in July), but rainfall has been minimal and we are in a severe drought. Couple this with the fact that the soil here is very porous and lacking in organic matter due to its composition with pebbles and stone (see the Site Evaluation, Articles, December 1st, 2021) and you have a recipe for struggle!

Of course, over time, the forest garden system will itself overcome these difficulties, by increasing shade and underground mycelial networks, and by improving soil humus, fertility and structure with the better water retention that that brings. But it will take a good few years and until then, I need to think seriously about providing more drought resistant species. This will mean researching genus and species which are also compatible with the aims of this Forest Garden, namely biodiversity, symbiosis, utility and resilience. I am taking this seriously enough to think in terms of putting this winter’s planting on hold, and maybe getting in touch with other forest gardeners in neighbouring Spain and Italy for their advice.
