The importance of irrigation in the garden and why it must be done in the right way

It cannot germinate without the presence of water, it can’t stand up (maintain turgor pressure), it cannot absorb minerals from the soiland it can’t photosynthesise without water.
A poorly-watered plant is a stressed plant. Really it’s a dying plant. Wilted leaves are more than a cry for attention; they are in many cases, death throes. Water is serious business.
