  • This time of the year as plants mostly slow their growth, is often seen as not a good time to be making judgments about soil conditions, since so many plants are about to shut down for winter and go dormant. Wrong!
  • This is the time to measure and observe. Measure your soil pH. That’s the level of acidity or alkalinity and it determines whether certain plants thrive or cark it next spring. Most vegies need slightly alkaline conditions and most bedding plants or flowers need slightly acidic.
  • Too acidic and your tomatoes get "Blossom-end rot" and have to be limed, which is increasingly becoming evident in our gardens as more gardeners strive for using organic (and acidic) methods or gardening.
  • It is not really practicable to get a nutrient soil test done in the average home garden to determine which nutrients need replacing, because all plants have different requirements and they are all extracting their N-P-K needs at different rates. So an analysis (unless you are growing just one crop), is a waste of time and money.
  • More important is to provide an organic buffer, through which plenty of nutrient exchange can take place and then provide that nutrient in diverse forms. Say water soluble fertilizers in the growth season and organic pellets of composted chickens at other times of the year, but to use "Blood ‘n Bone" all year round is like feeding your kids with Weetbix™ all day every day. There’s nothing wrong with Weetbix™ for breakfast, but it is not a complete diet and neither is just composted lawn clippings or blood meal for your garden.
  • The onset of late autumn when nutrients can break down slowly is a great bonus for the garden. So don’t see this season as armchair time that comes next month!
