Avicennia Marina is also referred to as Manawa or grey mangrove or Avicennia officinalis is a variety of mangrove from plant family Acanthaceae.

Overview of Avicennia Marina or Manawa or Grey Mangroves

• It is distributed along Africa’s east coast, south-west, south and south-east Asia, and Australia.
• Grey mangroves grow like a shrub or tree to your height of three to 10 metres, or nearly 14 metres in tropical regions.
• Its smooth light-grey bark is made up of thin, stiff, brittle flakes.
• The leaves are thick, five to eight centimetres long.
• They’re a bright, glossy green on the upper surface, and silvery-white, or grey, with really small matted hairs at first glance below.
• They have aerial roots.
• These grow to a height of about 20 centimetres, as well as a diameter of a single centimetre.
• The flowers vary from white to a golden yellow colour, are only a centimetre across, and appear in clusters of 3 to 5.
• The fruit contains large cotyledons that surround the modern stem of your seedling.
• This produces a large fleshy seed, often germinating around the tree and falling as a seedling.
• The grey mangrove can experience stunted increase in water conditions which have been too saline.
• They survive thus to their full height in both salt and fresh waters.
• The species can tolerate high salinity.
• They do this by removing salts through its leaves.
• Grey mangrove is a highly variable tree.

At present, three subspecies are recognized:
• Avicennia marina subsp. australasica
• Avicennia marina subsp. eucalyptifolia
• Avicennia marina subsp. Marina

Growing/Caring conditions for Avicennia Marina or Manawa or Grey Mangroves

• Pour silt into a 12-inch plant pot.
• Fill the pot within one-half inch from the brim.
• Make use of a watering pot to water the silt.
• Mangroves require moisture to thrive.
• Water the silt until it’s saturated and muddy.
• Scoop up a small hole with one of your fingers nearby the center with the silt.
• Position a mangrove seedling inside hole.
• Ensure the hole is deep enough so the seedling’s roots are placed below the top of the soil.
• Push the soil back over the opening to hide the seedling such that the stem shows above the silt.
• Water the seedling daily.
• Ensure the silt remains damp continually.
• Use a saltwater solution, as opposed to fresh water, once per week while watering the seedling.
• Use ocean water if available.
• If ocean water is unavailable, make a solution of 1 liter of water blended with 2 teaspoons of salt to water the mangrove seedling.
• Plant the seedling in the saltwater aquarium once it starts to come to be a little daughter tree, or you can leave it at the table as an indoor plant.
• If your mangrove tree outgrows its original pot, transplant it to a larger pot to make certain its root has enough room to inflate.
• Continue the daily freshwater and weekly saltwater regimen over the lifetime of the mangrove tree.
• Avoid transplanting your mangrove tree later on by planting the seedling inside a large pot that could allow it space growing.
• Soil conditions with a PH value of 6.5 to 8 is required.
• Water your mangrove tree immediately if you see the silt starting to run dry.
• Deficiency of moisture could cause your mangrove to weaken or die.
