I went for a walk along the new earthworks this morning. We’ve yet to do the fine work with the spades so the pond in particular is still a little rough, so I wanted to see how much digging I’m in for this weekend. What I found was almost two feet of water. Superb. The top of our field is the ridge in the landscape, so it’s from the water table. This area is covered with wells and springs, but you can’t just sink a hole anywhere and hit water. We have a deeper, older ditch that was originally dug to take the water from the barn and it’s occasionally wet at the bottom (oo-er!) The new pond has water barely a metre down, and it’s not rain water. I noticed when I was using the digger that at one point I had water flow, but this is a lot more than I was anticipating. If this is reliable through summer it’s a huge deal. Over time we’ve always planned to take the croft off grid, so reliable water for livestock makes life a lot easier. What’s stunned me is that this water already has a pond skater. This pond is less than 24 hours old and someone’s moved in.
There’s a spot right at the top of the field that’s reliably wet. If we can develop that into a functional spring, we could gravity feed that water to anywhere on site. It’s starting to look like the site design has acquired another pond.

I know, I know, it’s been ages. I promise we’ve been very busy though. One of the frustrating things about having this blog is that when we’ve been doing interesting stuff we’re generally too busy to spend long blogging. We’ve had a couple of weeks of good weather, so have cracked on.
The front garden is almost finished. We’re waiting on a load of wood chip to be delivered. Once that’s spread over a load of cardboard it should take out the ground elder and few flowered leek. We’ve kept some of the leek in a pot, for something a bit different in the herb garden, but it can get away from you in the ground.
We finished marking the swales in the top field. We’ve bought a load of reclaimed timber to build a decent shed and some other reclaimed bits and pieces for the back garden. I’m sure I’ll blog about them when we get to it.
Best of all however is we’ve made a start on the earthworks! We hired a mini digger to level the shed site and booked an extra day to get a few other jobs done quicker. I must admit, I love it. It just gets things done so much faster and easier, it’s worth every penny. I’ve dug the lower swale and made a start on the integrated pond. I’ve designed it to work a little differently from a conventional swale. Rather than hold water until it infiltrates into the ground, this one drains into the pond at the end. It can be turned very easily into an infiltration swale, giving us the option to regulate the hydrology of the site throughout the year. The digger goes back after tomorrow so I’ll not manage to dig the other two this time, but it’s encouraging to see some of the main system components going in.
It still needs a little tidying with spades to finish, and I’ll need to go out during the next major rain event to tickle the spillway from the pond, but you get the idea. That digger will be back to visit again very soon I suspect.

Bucket is wise. Bucket can tell us things. Bucket can be a surprisingly illuminating diagnostic tool. Hang on and I’ll tell you all about it.
I dug this hole back in March, so I could use the soil as a mound for the hazel tree we planted on it. We have many such holes around the croft that were dug at the same time, and they’ve been surprisingly interesting. We knew the ground here gets saturated very quickly when it rains very soon after buying it. As soon as we started planting we learned that we had roughly 18 inches of good topsoil over clay subsoil. Since we intend to dig ponds eventually this was excellent news, but it affects the hydrology of the site. At least one of us walks the fence line every day, checking the trees, so it’s easy to keep an eye on these holes. Immediately after rain they have up to four inches of water in them, draining to an inch or so within three days, and being no more than moist within four to five days. I put this down to a combination of water being infiltrated into the ground and the drying effect of the wind. Soon after we planted the trees I found the bucket jammed between some rushes. I shoved it into the hole so it wouldn’t blow away, intending to pick it up later, and promptly forgot about it until every time I passed the tree.
It added another dimension to water table observation. I’d read about using a bucket to monitor rainfall in a book I read years ago, but the author hadn’t thought of sticking it in a hole to get two sets of data. I really wish I could claim credit for it properly.
Typically, you stick a bucket somewhere it won’t blow away and watch it over a year. It’s as simple as that. If it always has water in it you have a wet climate. If it often dries completely you have a dry climate. All pretty obvious so far yes? Where it’s useful is in determining unusually dry spells, when pasture may need extra water to stay alive. Unlike proper rain gauges the bucket factors in moisture lost to the wind. It won’t however factor in moisture lost to ground infiltration, but my hole does (seriously, stop sniggering). Rain in Caithness is regular but not very often too heavy. In terms of inches of precipitation it’s similar to Kent, apparently. Windier though. The bucket has so far not gone beyond half full, but hasn’t gone lower than four inches deep either. The sun and wind evaporate the moisture fairly consistently, so will be having a similar effect on the pasture. Our soil isn’t waterlogged, it’s intermittently wet because moisture is slow to percolate through the clay subsoil. And that can be fixed easily through sensitive earthwork construction. It’s a game changer for our understanding of this site. And that, I think you’ll agree, isn’t a bad result from a forgotten bucket.

It’s been a few days since the blog was updated but we’ve had a busy week. I finally finished the worm bin, I’ll post an update on that this week. Last weekend, however, we decided to finally crack on with the front garden. It’s overrun with three cornered leek and ground elder, both of which can tend towards unruly, so we intend to mulch it out. I don’t mean with three inch thick stone either (though more on my stone mulches in a bit). I mean good old-fashioned wood chip, organic mulch. Before that though, the daffodils and snowdrops needed rescuing. You’d think that just digging up some bulbs from a four by eight metre garden wouldn’t take long, wouldn’t you? After all, the flowers only occupy the edges, right? Easy! It would be too, if it wasn’t for all the stone and all the plastic. I’ve taken to stacking the stones according to size now. At least we can find uses for the stone, but the plastic we’re digging up is becoming ridiculous. I filled a bin bag sized rubble sack in 20 minutes this morning. How many snowdrops did we dig up, you ask? Good question. let me show you.
That’s just the first barrowload. There’ll be another tomorrow afternoon. That one is about 75% snowdrops, the rest being daffodils.
We’ve underplanted the trees and shrubs in the shelterbelt pretty thickly. I’ve recorded some video explaining the design of the shelterbelt, I might even post it if I can get the hang of the video editing! The bulbs aren’t strictly part of the design of the polyculture we’ve put in, but they should look stunning next spring.
Other jobs we’ve cracked on with are my ongoing battle with the back garden stone fence (over halfway now) but we’ve had another small development in that area. This morning I saw a Facebook advert for 500 stone slabs. Now you might think we have enough slabs to be getting on with, but apparently not. So far we’ve managed to get half of them home. They’re sitting out there now, looking all gorgeous, hopefully intimidating the creeping buttercup. I know, I know, but they will shorten the war by at least six months.

Do you feel excited when reading seed catalogues and make a long mental list of all the seeds you want/need/covet? Does the arrival of fresh new packets of seed make your breathing quicken and your heart sing? Me too! Build a little seed bank in your soil (with apologies to They Might Be Giants).
Just look at these beauties:
I’ve planted the watercress in the ditch at the other side of our lane, where the overflow from the septic seeps. It’ll polish the water, provide habitat, look more interesting than a damp ditch and give us a sustainable source of seeds to harvest, to use once we’ve created ponds.
The flower seeds have been sown in various locations: along the lane, round the berm next to the old croft house, along the top of the field next to the wild seeds we’ve planted. I’ve saved some, such as the red sunflower, to bring on in pots as well. The sainfoin is a good forage crop for ruminants and we’d like to get it naturalised here; it’s also nitrogen-fixing, as is the lupin. All the other flower seeds, such as the cornflowers, are great for encouraging bees and other pollinators, but also for creating delicious, sweet hay. Of course, it’ll make the site prettier to look at as well, which is a bonus: where practical and idealistic meet. Beauty is a yield too.
