Arrange the bales in whatever configuration is convenient for your style of gardening.

Some gardeners fill these spaces with additional compost/soil mixture as they appear.

Proper prepping requires a week to 12 days.

Add more fertilizer every couple of days, spreading it generously, then soak the bales each time.

During the warmer months, your straw bale garden will need to be watered at least once per day.

In cooler months, two to three times per week is usually sufficient.
