Italian Oregano is a cross between Sweet Marjoram (Origanum marjorana) and Greek Oregano (Origanum Vulgare). It is touted to be the best all purpose Oregano as it holds the sweetness from it’s marjoram parent and retains some heat and spice from the Greek Oregano lineage.   

The most popular Oregano variety, Italian Oregano (Origanum majoricum) has a sweet and spicy flavor that is considered the ‘True Pizza Herb’ by many and lends itself well to Italian, Mediterranean, and Mexican cuisine. Use with vegetable and meat dishes, or add to herb breads, butters, and vinegars.

Soil Preference for Italian Oregano Herb Plants / Origanum vulgare subs. hirtum / Origanum vulgare heracleoticum:

Italian Oregano herb plants do not require extremely fertile or moist soils to grow and thrive, but Florida’s sandy soils will still benefit from amending the soil with a good quality compost when planting.

Avoid using cow manure or Milorganite, as these will help the soil to retain moisture and Oregano prefers the soil to be a bit on the dry side.

In Northeast Florida, unless you have a sandy garden spot, planting Italian oregano in dry soils may prove to be a bit difficult during our rainy seasons. If planting your oregano herbs into the ground consider adding some sand to areas where water will stand after rains, or planting your oregano into raised beds, elevated mounds, or into containers.

However, in Florida’s sandy soils you may find your plants in some need of som help, particularly if compost wasnt added to the soil when planting. Try fertilizing with a mixture of fish emulsions and seaweed at one ounce of each per gallon of water. Put into a sprayer and water every other week or as needed with the mixed solution.

If you find your plant struggling at any point, make up a batch of compost tea and water generously. Repeat as needed weekly or biweekly.
