Hose pipe ban in parts of UK

Filed under: Uncategorized — Tags: , — TopVeg @ 9:41 pm

Seven UK water authorities have announced that a hose pipe ban will start in April.  Lack of rain over the last two years is causing a shortage of water.

Any irrigation using a hose pipe is against the law when a hose pipe ban is in place.

Vegetable gardeners can act now to save water and plan for the summer growing season.  Things to do include:

  • fixing leaky taps – a leaky tap can waste about 90 litres of water a week
  • collect rainwater from the roof of dwellings, garages, greenhouses etc..& store in various containers
  • install a water butt to collect rainwater.  Check your local water authority website as they often have offers on water butts.
  • water plants with a watering can
  • clean patios and paths with a bucket and brush rather than a hose
  • mulch beds to reduce water loss by evaporation

Gardeners can act now to mitigate the affects of any hose pipe ban which may come to your part of the UK.

Driest March since 1961

Filed under: Uncategorized — Tags: , , — TopVeg @ 8:54 pm

March has been the driest since 1961 for England and Wales,  according to  Dr Liz Bentley of the Royal Meteorological Society, & founder of the Weather Club

Dr Bentley  says the next few weeks could be critical for water companies, farmers and wildlife, and could determine if there are hosepipe bans later in the year.  Farmers & gardeners have already started to water their crops.

It is unusual to irrigate crops this early in the year & it is due to lack of rainfall over a prolonged period.

The Big Butterfly Count  newsletter says that ‘despite the incredibly cold weather last December, butterflies and moths have got off to a ‘flying’ start this year. February was a very warm month, by normal UK standards, and March was much drier and sunnier than average.’   In fact it was the driest March since 1961.

Watering newly planted seed

Filed under: Uncategorized — Tags: , — TopVeg @ 10:02 pm

ben_short on Twitter, has asked TopVeg “any advice on avoiding creating a surface pan when watering a newly planted seed bed?”

This is a very interesting question, which requires a longer answer than the 140 characters allowed on Twitter!

1.  Give small droplets of water – using a very fine rose on a watering can, or a spray.  This will not swill the surface like water from a hose pipe

2.  Retain small cloddy bits of soil on the surface, to help keep it open.  It is good to have fine soil around the seed to give plenty of soil/seed contact.  The seed can then take the water from the soil & start to grow.  But the surface of the seedbed should contain little lumps of soil, so that it is not a powder which will soak up water & then dry into a hard sheet or cap.

3.  When raking the seedbed do not collect up all the small bits and clods to leave totally fine soil.  Fine, powdery soil will run together when wetted, & then go solid when it dries out.

4.  Do not overwork the soil, leaving a very fine soil on the top.  The fine soil will go hard after a wet & a dry.  The germinating shoot will not be able to push through this hard cap.

5.  On clay/loamy soils,  sow seed into moist (not wet) conditions.  Before watering the seeds in, let the surface of the soil dry out a little so that the small cloddy particles go hard.  Then they will repel water and not melt when wetted.

6.  Be careful not to over water and make the soil water- logged.  Too much water will fill all the air spaces – pushing all the oxygen out of the soil.  It is better to water little & often, maintaining a permanently moist (not wet) soil.

Watering a newly planted seed bed requires lots of attention to detail!

Using Drip Tape

Filed under: Uncategorized — Tags: — TopVeg @ 11:00 am
We have been using drip tape for about 5 years to water the vegetables in a dry time.
drip-tape-on-potatoes

drip-tape-on-potatoes

We do not lay the flat drip tape below the surface of the soil.  It would be difficult to detect problems in the tape if it was below the surface.
The water pushes the soil particles away from the pipe so the soil does not clog our tape.  Roots could be a problem if it is down for some time, but we have not had a problem with roots.  It could depend on the quality of the tape.
Alkaline soils cause the tape to block with lime scale.  The tape has then to be unblocked with acid & this is easier to do & manage if the tape is on the surface.
We are in the UK, where the climate is temperate.  So the tape does not get very hot, & expand.  In hot countries, the tape will expand in the heat & wiggle about a bit, which may make harvesting difficult if you are trying to avoid the tape.
The tape will be damaged if a reaping machine catches it. But gardeners using a hand-held fork (to dig potatoes) will also damage the tape if they are not careful.
Because of this I lay the drip line on the surface down the row, and remember where it is, so that I can avoid it when harvesting.
The evaporation loss, because it is on the surface, is insignificant.
Using drip tape with care protects it so that it can be used year after year.

Drip Irrigation on Potatoes

Filed under: potato — Tags: , , , — TopVeg @ 2:31 am

Drip irrigation has several advantages when used on potatoes:

  • saves water
  • waters more evenly
  • waters more gently

The drip irrigation pipe can  run either  on the soil surface or in the soil.  In the photo below the drip irrigation pipe is on top of the potato ridge, so that it will be under the leaf canopy.  Loss of moisture from evaporation will therefore be reduced.

The next picture shows the hole in the pipe from which the water continually drips.

Drip irrigation on potatoes is an efficient way of watering potatoes and a good way to increase yield.

Selenium – an essential micronutrient for plants

Filed under: Uncategorized — Tags: — TopVeg @ 12:41 pm

Selenium is an essential micronutrient for plants.

In dry conditions, selenium:

  • regulates the plants’ water balance
  • postpones senescence
  • protects plants from sunburn

Studies at the Jozef Stefan Institute of the University of Ljubljana, Slovenia, demonstrate that selenium is an important micronutrient, playing a vital part in the drought resistance of plants.

Water Newly Planted Trees

Filed under: Uncategorized — Tags: , , — TopVeg @ 2:08 pm

Water and mulch newly planted trees, to avoid wasting all the effort spent digging the hole and planting the tree.

If the soil around the tree is very dry, it will need several buckets of water. Once the soil is wet, cover it with lawn mowings or another mulch.
When the tree has been mulched it will not need watering so often.

Trees planted before Christmas have had time to develop roots and benefit from the winter rains.

Trees planted after Christmas, nearer to the Spring, have an increasing problem getting established.

* The disturbed soil in the planting hole will dry out easily. There will be problems with capillary action, and water will not be able to rise up from the subsoil.
* The tree will want to grow in the spring.
* As bare rooted plants come out of the winter, they will start to produce roots. But the disturbed soil will not provide a suitable environment for rooting.
* The disturbed soil will not have sufficient water and nutrients to enable the tree to keep growing.

Therefore the newly planted tree will need extra water.

Scrape away a bit of soil from under the tree with a hand. Squeeze the soil between finger and thumb. If the soil stays together it is wet enough.

To check if a mulched plant needs water, move some mulch out of the way, to feel the soil beneath.

It is easier to keep the soil topped up little and often. Once the soil has dried out, it is more difficult to wet because the water runs through the gaps in the soil particles. So it takes more water to wet baked-out soil.

It is very difficult to over-water a growing tree, as the water will just drain away.

When wet soil is mulched with lawn clippings, the moisture is retained.
Mulching is the key to a healthy, well-grown tree.

Look After New Trees

Filed under: Uncategorized — Tags: , , — TopVeg @ 2:02 pm

Give young trees the care and attention they deserve, to ensure a payback on the hard work undertaken in planting them.

* Keep the soil around them moist
* Mulch around the base of the tree
* Check the stake is secure so that the tree does not rock and dislodge its roots
* Heel the tree in again. To heel in, press the soil down around the roots with the heel of the foot. This will ensure root to soil contact.

When the tree is planted in wet soil, the disturbed soil will dry out and shrink. The soil then becomes loose. Then the roots are not in sufficient contact with the soil to take up sufficient moisture.
