Last year I ran the bath water on the front garden via a hose connected to seeper hose but it took a long time for the water to filter through. So I finally got round to organising a watering system for the front and back garden using rain water from the roof and what a difference it has made. All my plants made much better growth than in any previous years.
I don’t have the patience to stand watering the garden with a hosepipe and have never had a spray system, if I had I’m sure I would have left it on by mistake and racked up a terrific water bill – we are on a meter, so a seeper hose system was the obvious answer. It was reassuring to read a typical drip irrigation system uses up to 92% less water than a hosepipe and is a far more efficient way of watering the garden – www.the-hta.org.uk/water.
The system I devised for the back garden, after a lot of head scratching and frustrated thought, was to put in place rain diverters on the downpipes from the roof, attach a hose to that which led to the seeper hose system. When that overflowed the rain was diverted back to the downpipe and on to another diverter that was connected to a water butt. When that overflowed the water then feed back into the downpipe to the main drainage system.
The roof on a house collects about 85,000 litres of rain each year in the UK which runs straight into the sewers. This could fill 450 water butts which can be used to water garden lawns, vegetable patches and house plants.
Altogether I used 6 x 15 metres of hose and linked up some small supplementary hose to water the pots on the patio via a separate water butt which made a huge difference to those plants.
Then in times of drought the water butts are linked up to the seeper hose. I generally leave them on for about 4 hours when needed. Now you may feel this sounds all rather complicated and at the time I thought so too, but it in reality it works and is very simple in action. The key is to make sure the water flows in at a slightly greater height than the ground you are watering.
At the moment although there is a hosepipe ban, seeper hose systems are exempt where we are, so when the water butts are empty, I can link the outdoor tap to the seeper hose system and to the water butts. Check the website of the water company in your district to be sure.
Not all parts of the garden need to be watered, for instance the peripheral areas with the wild flowers – bluebells, muscari, oxalis – that look after themselves, so I inserted sections of ordinary hose to bypass those areas. It meant adding connectors which increased costs.
What is important to remember is to cover the hose with mulch or set it into the ground and cover with earth and then mulch – by far the most efficient arrangement, it keeps the moisture in the ground which evaporates very slowly.
Overall, when it rains the garden gets about third extra which is all stored under the mulch. Another important point is to water at night, again to reduce evaporation.
So what plants are important? Fruit trees, crops like peas, climbing beans and broad beans, broccoli, cabbages, spinach, carrots, beetroot, onions, tomatoes, salads, kale. All these came good last year even when we had extended periods of drought. This spring I have noticed the fruit trees all have much more blossom than in previous years.
I have been really interested to see that plants grow slowly but steadily through the winter. I think it might be because the thick layer of mulch keeps the cold off the roots. I try, but seldom succeed, in putting at least a depth of 8-9 inches of mulch/compost/manure, which by spring time has been processed to some extent by the worms which means the ground is very easy to prepare for seedlings and plant plugs.
I sow annuals in with my vegetables to make it look less like an allotment. Nasturiums look really good, loving the extra moisture.
This year I have seeds of african marigold, red cornflowers, calendula, nigella and poppy to scatter through the garden. Attracting beneficial insects makes a difference to the life of the garden, they attract birds, making the garden more alive. Better than just putting out nut and seed feeders.
This year I interplanted self sown garlic plants found all over the garden with Malwinnie strawberries as they help the berries to fight disease. I had tasted these at the 2011 Thompson & Morgan Press Event and they were dribblingly good! Will have to think of some surefire way of keeping away the mice, birds and other creatures that know a good strawberry when they taste one!
Carrot, beets, kohlrabi, brassicas, dill, lettuce and tomatoes all do well when interplanted with the onion family.
