About Dittany of Crete

Origanum dictamnus · also called Dittany of Crete, Hop Marjoram · herb

Dittany of Crete is an ornamental Cretan oregano with rounded woolly silver leaves and pendulous pink hop-like flower bracts, prized in herbal tradition and as a trailing rockery or container plant. A tender alpine perennial, it needs sharp drainage, full sun and protection from winter wet and frost.

Mature size: 20-30 cm tall, trailing/spreading 30-40 cm wide

Watch for — Winter wet and frost: Damp cold kills it. Grow in a gritty pot moved under cover, or in a sharply drained, sheltered spot over winter.

How to tell dittany of crete needs repotting

Repotting on a calendar is less reliable than reading the plant. For dittany of crete, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot dittany of crete

Every 2–3 years, into bone-dry mix.

What size pot to step dittany of crete up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Dittany of Crete stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot dittany of crete

Spring or summer, while dittany of crete is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting dittany of crete

Repot dry. Do not water dittany of crete for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty gritty, sharply drained alkaline alpine soil ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set dittany of crete at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep dittany of crete completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for dittany of crete

Dittany of Crete wants gritty, sharply drained alkaline alpine soil. Use a free-draining mix with plenty of grit, like an alpine or cactus blend. Standing moisture is fatal; a gravel mulch keeps the crown dry. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
