Watering plants: how much and how often?

Here is an interesting article on http://www.telegraph.co.uk. Watering your plants can be a very annoying task provided you know how to do it. You can either use a watering can or garden hose pipe to water your garden. The area and the kind of plants you grow in your garden matter in the case of watering your garden.

With my veg garden, which I water by hand, this is vital and you need to water in new plants generously so the plants will be encouraged to grow new roots which will follow the water down. When it comes to watering, pot plants are the most demanding. In garden many pots have had their bases removed with a small disc cutter and sit on soil.


Claber do a kit (the 90766 Drip starter kit) which includes a versatile Logica timer for around £50. This includes drippers, spikes and connectors and it allows you to put your pots on a system that you can install. It will do around 20 pots.

You do not want to irrigate your lawn. Cutting it longer, using a mulch mower and occasionally dragging out a sprinkler keeps it just presentable. Claber sells a sprinkler kit (with pop-up sprinklers) that you can install for £100. It covers 50sq m. The biggest problem with irrigation is a temptation over-do it.

Watch for signals of slight stress then apply. With vegetables, although yields increase with water, the flavor almost invariably decreases. Timing varies with different crops beware carrots, parsnips, beetroot and radish too much water gives you lush foliage; watering when very dry often causes splitting.


Water roots just every three weeks or so before the soil gets dry. To produce earlier early potatoes don’t water until the tubers are marble sized, then apply one good watering about four gallons per square yard. Tomatoes kept quite dry until flowering encourages growth of the root system and hastens fruit production.

Fine mulches absorb moisture and keep water on the surface, which draws roots up not the best idea. Careful monitoring to assess how much or how little water plants need saves time and money. If you aim for soil with great structure (add organic matter) you may well get away with no watering of vegetables, even for courgettes. And the flavour will be far better to boot.

You will also need pipe attachments and a few additional bits and pieces, but you can easily install this yourself.
