One important aspect of permaculture is to use nitrogen fixing plants and trees to enrich the soil with nitrogen. Geoff Lawton refers to them as "legume" trees List of Leguminous Plants. Ummm...I had never heard of such...so I began to research. Then I realized that I have several nitrogen fixing trees already in my garden and this is one of them. It's a very beautiful plant and if it dies down from a freeze it returns from the roots. I've heard of it growing well as far north as Georgia.
Cassia bicapsularis pronounced KASSee-uh bye-kap-soo-LAIR-iss From what I have read, Leguminous Plants produce pods that contain it's seeds.
"Pride of Barbados" plant also makes pods containing it's seeds. It's in the "pea" family so it too is a nitrogen fixer. Also the "trash tree" as some people call it, Mimosa is also a nitrogen fixer. Mimosa has earned it's name as a plant that rushes in when the soil is empty an begins to grow. It really deserves the name of "healer" since it protects the soil from being swept away, drops it's flowers and leaves to nourish the soil with organic material, and it's roots grab nitrogen from the air and fixes it in the soil making it available to other plants. I have so much to learn.
My newest pear trees are drooping with fruit even though over half of the fruit was removed to keep it from taxing the small branches.
Here is a view of the front garden looking toward the raised bed garden. The Aztec grass really pops in front of the weedy look of the guara. Guara is prettiest in the morning when it's blossoms have freshly bloomed. By mid afternoon the flowers have wilted and all the busy bees have finished harvesting it's nectar and are busy elsewhere. In the morning guara vibrates and hums with industrious bees mining it's gold. The guara in this part of the garden volunteered from some guara that I planted near the door.
Muscadines! The vines are slowly covering the trellis in their second year. Next year I expect them the completely cover it and need to be trimmed severely!
Some of the satsumas are already showing a little bit or orange!
The navels are getting plump!
And ....Oh yes, I've harvested quite a few perfectly ripe watermelons! Success at last! Yummm!
