To prevent future flooding there is a need to manage the land in a different way. The dredging of rivers will do nothing but speed up the flow of water to ‘pinch points’ further upstream. The use of sandbags is a measure provided too late, when normal life has been halted by water flowing into homes.
Natural Flood Management (or NFM’s) must now be considered a major part of flood prevention. The critical factor of NFM measures? The planting of trees to slow down running water.
By planting trees near headwaters they act as a buffer to hold up rainwater runoff. Planting woodlands near streams works in exactly the same way, slowing down the water. Debris from the trees can also fall into the river, creating dams that hold back excess water. These ‘timber flow interventions’ can even be man-made, by laying fallen tree trunks into the stream. These are far cheaper measures than building bigger walls to protect towns.
Trees also help water percolate into the soil (60 times faster in some research) although infiltration will be reduced if the land is already saturated. If this is the case, what options do we have then? Short-term, we are back to the sandbags. Long-term though, we lessen rainwater runoff rates from poorly managed land. How do we do that?
Treat our soil better.
We could stop winter sowing of crops. This leaves the soil bare for months. With nothing to bind it together it turns into mud when wet and leads to land erosion. The sowing of a winter ground cover would benefit the soil as much as preventing flood damage.
Stop compacting the soil with heavy machinery and too many animals walking over it. Compacted land works the same as any impermeable surface – it cannot take the water, so the water must just run off and down streets and into homes.
Add organic matter to the soils. They will hold more water, yet won’t become waterlogged.
Is there anything else we can do?
Don’t build houses on floodplains. This may alleviate housing shortages in the short-term, giving whichever Government bragging rights over what they have achieved while in power, but the problems will arrive later on… and money will still have to be spent on rebuilding, on rehousing, on healthcare for people who are having to live with stagnant water around their ankles. The costs will always catch up with us in one form or another.
Concrete and dredging are all very well – but we need to slow water down, and give it places to sit and be held when it does become to much.
We need to plant trees, we need to cherish and protect our floodplains, and we need to look after our soil.

Over the last two years I have been involved with a couple of projects that have ended up being recorded, then placed on Youtube or Instagram. I’m hoping they will be useful to you, so I have decided this morning to pop them together in one handy blog post so that you can bookmark the page and revisit when you need some inspiration for your topiary. See below then, a few videos about topiary I have recently been involved with… Garden Masterclass – Provocations of a Modern Topiarist Transforming Topiary Topiary Teacher Put On The Spot https://www.instagram.com/p/CTj-EfOKRL6/ In the above …
Mark Zlotsky is an artist based in New York, and today I just wanted to share his project ‘Topiary Tango’. In his introduction to the project he talks of topiary being a forgiving art, which I love and is soooooo true…..! For proof, just take a look at some projects I have made with a sharp pair of shears, a hedgetrimmer and a pruning saw. Do check out Mark Zlotsky’s project, because although his interest began by looking at topiary through the prism of architecture and the relationship of one building to another, he touches directly onto a way of …
Gardenista, the online magazine about gardens and design, have interviewed me about topiary. The article is called ‘Rethinking Topiary: A Garden Tradition Loosened Up’ and was published this morning. Written by the excellent garden writer Clare Coulson, I share some thoughts on using deciduous plants, how to clip (name-dropping Anne Lamott and her book on writing at one stage… oh, how I wander off subject sometimes!) and how to improve topiary by what you plant around it. Do take a look at the article in Gardenista. Or for more about my topiary work, check out the topiary page.
