    How nice is it to have the produce from your backyard freshly picked? 

    The details about the fertilizer and the pH requirement add to one’s knowledge for growing appropriate seasonal produce and flowering plants.

    I never knew we could grow spinach now for the fall. Thank you for sharing essential knowledge with the world.

    I took the liberty to share your post with my husband in facebook.

  2. Hey thanks for this post!

    This is a really interesting and useful post for me as I wanted to grow something but was having second thoughts as it’s nearing towards autumn and winter. There are so many plants to harvest I’m surprised, I always thought summer or spring was the ideal environment. Definitely going to be considering planting some of these, currently spinach, tomatoes and cauliflower from the veg are on my list and pansies and marigolds from the flowers.

    Thanks again for providing this information!
