The MiracleGro/Scotts 24-8-16 is a good formula for citrus, ornamental bananas (e.g., basjoo), and for general growth of subtropical plants. Use 1 level Tablespoon per gallon for periodic feedings (once every 2-3 months) or 1/3 to 1/2 level teaspoon per gallon continuous feeding (with a permanent injector).

Check your soil pH before adding the contents of tea bags, coffee grounds, etc. If it is already below 6.5, leave them out.

Any of the scraps (including tea, coffee) you mentioned should be composted with a "core" temperature of 140F or greater for 90 days before mixing into the mulch on top of the soil. Do not dig compost into soil around plants. You will destroy developing root systems -- which often have "hairs" in the soil that you can only detect with a magnifying glass.
