Flooding (Part 2)

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.

EBTS Boxwood Growers Forum

Through the European Boxwood and Topiary Society I worked with Chris Poole and Sue Mesher, members of the EBTS board, and we set up a Boxwood Growers Forum. This was to discuss how to make sure this wonderful topiary plant stays in the public conscioussness – we know many growers, suppliers and distributors have stopped selling it as the cost of replacing boxwood that has blight, or is nibbled by the boxwood caterpillar, makes it unviable to offer to clients and gardeners. But Boxwood is a phoenix plant, and there are ways to deal with the problems associated with Buxus. …

Modern Topiarist @ Garden Masterclass Poland

My video on Modern Topiary for Garden Masterclass has been translated into Polish, for the keen gardeners (and happy pruners!) of Garedn Masterclass in Poland. Tickets for the first showing and q and a were available here. But it will become available on the Garden Masterclass Poland website at some point in the near future – so if you are a keen clipper and want to know more, but speak Polish and not English, then I suggest you visit the website and get watching. (Of course, if you don’t speak English, you may not be able to read this…. hmmm… …

Topiary Hotline

The European Boxwood & Topiary Society are to run a Topiary Hotline for keen gardeners and people who love to clip. Date is tomorrow, April 16th 2024, and you can get a ticket for the Zoom meeting here – Topiary Hotline. Run by Chris Poole and myself, we set this up as an antidote to the huge amount of questions we have to answer about topiary throughout the summer. The plus is that their is an excitement around topiary and pruning. The problem is we need to help people in a better way… … so we will be giving people …
