There's nothing so awe inspiring, economical or time saving in the garden as direct sowing seeds into the garden. 'Direct sowing' means simply to plant seeds into the final growing position either into the garden soil or into a pot. This is as opposed to sowing seed into containers to be transplanted later as seedlings.
Just why it is so awe inspiring is that a seed is so much smarter and hardier than most people think. A seed is smart as it will germinate only when conditions are right, such as temperature, day length and moisture levels. This is why certain plants that have 'self sown' in the garden will wait until the right time of year to come up, coriander, basil and many 'weed' seeds for example.
A seed is hardier than you may think as the 1st thing it will do after imbibing water and starting to breathe more deeply is to throw a root down into the ground to find lovely deep moisture to draw from. The more water and nutrient the roots find, the faster and bigger it's above ground parts will grow. It will grow within it's means so to speak. Even though the root will go as deeep as it can, don't forget, the smaller the seed, the more shallow it must be planted and the more shallowly planted, the faster they may dry out with the sun and wind. So give your growing vegetable seeds water and nutrition so they may feed you well in return!
