Sowing seed for the garden
Have you started sowing seed for your vegetable garden? For your perennial garden? For annuals in the coming season?
There is a science to being successful in this endeavor. Remember this key statement when attempting to sow any seed for your landscape: “There is an optimal or best temperature for every species or kind of seed. At the optimal temperature, you get the highest percentage of seed that germinates or sprouts.”
Most common garden annuals and vegetable seed need a period of dry storage before they will germinate. This is according to the research of Dr. Norman Deno, published in his work titled “Theory and Practice of Seed Germination.”
Their germination temperature is placed at 70 degrees Fahrenheit. The following is a list of seed that germinates precisely at 70 degrees Fahrenheit: New Zealand spinach, leeks, celery, celeriac and salsify.
Those crops which germinate best at 75 degrees Fahrenheit are as follows: asparagus, lettuce, onion, parsley and pea.
