Mixture for germinating seeds?

I live in a remote area (tropical) and am having trouble germinating some flower seeds. I have available a fairly good topsoil, sand, and a composted mix sold in bags.


What is the best proportion of these that will give me the best results?

The sand has to be clean. No road salt in it.


The topsoil has to be dry, and fine, the sand also should be dry.


The composte should also be fine and dry.


Then try 1/2 topsoil 1/4 sand 1/4 compost.


Then, CAREFULLY add a little water. You want to dampent the mix without getting it wet, as in mud.





A much simpler solution would be to buy some Jiffy Mix at a garden store. Inexpensive, and works well for most things.
Reply:As you live in a tropical area it would be interesting to know what you are trying to germinate





Here in the UK we grow wallflowers out side, in South Africa they have to grow wallflowers in a shaded poly tunnel
Reply:Place a few layers of paper towels in a shallow bowl, place seeds on paper, then cover with a few more layers of paper towels Make sure to keep moist, and the seeds will germinate. Be very carefull when trying to plant in soil medium. I use small tweezers for this stage and have had very good luck.
Reply:what do you intend to grow.
Reply:OK, you'd be talking a starter mix. 50% Peat Moss, 25% Perlite and 25% Vermiculite. This is your basic mix which is good for acidic loving plants. If you need to sweeten the mix (less acidic), you'll need to add dolomite (agricultural lime), 1 tablespoon / 4 liter vol. (gallon). Using garden soil is not recommended until transplanting.
