About Barbecue Rosemary

Salvia rosmarinus 'Barbecue' · also called Barbecue Rosemary · herb

Barbecue Rosemary is an upright rosemary cultivar bred for long, straight, sturdy stems that strip clean to make natural skewers for grilling. Aromatic and resinous, it is a sun-loving Mediterranean evergreen wanting sharp drainage and dry conditions, and it tolerates drought once established while resenting wet, heavy soil.

Mature size: 120-180 cm tall, 60-90 cm wide

Watch for — Root rot: Wet, heavy soil rots the roots and yellows the plant. Use gritty, free-draining soil and water only when dry, especially in winter.

How to tell barbecue rosemary needs repotting

Repotting on a calendar is less reliable than reading the plant. For barbecue rosemary, 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 barbecue rosemary

Every 2–3 years, into bone-dry mix. Barbecue Rosemary's growth habit — vigorous, strongly upright evergreen shrub with stiff, tall, straight stems and narrow resinous needle-like leaves, more vertical than typical rosemary. — sets the pace. Barbecue Rosemary is an upright rosemary cultivar bred for long, straight, sturdy stems that strip clean to make natural skewers for grilling. Aromatic and resinous, it is a sun-loving Mediterranean evergreen wanting sharp drainage and dry conditions, and it tolerates drought once established while resenting wet, heavy soil.

What size pot to step barbecue rosemary up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Barbecue Rosemary 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 barbecue rosemary

Spring or summer, while barbecue rosemary 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 barbecue rosemary

Repot dry. Do not water barbecue rosemary 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 sandy, gritty, well-drained neutral to alkaline 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 barbecue rosemary 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 barbecue rosemary 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 barbecue rosemary

Barbecue Rosemary wants sandy, gritty, well-drained neutral to alkaline soil. Sharp drainage is critical; amend with sand or grit. Rosemary hates wet roots and heavy clay, so raised beds or terracotta pots help excess water escape. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting barbecue rosemary — frequently asked questions

How often should you repot barbecue rosemary?

Every 2–3 years, into bone-dry mix for barbecue rosemary. Repot barbecue rosemary every 2–3 years into a snug pot of sandy, gritty, well-drained neutral to alkaline soil, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does barbecue rosemary need?

When is the best time of year to repot barbecue rosemary?

Should you water barbecue rosemary after repotting?

No — not straight away. Repot barbecue rosemary into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise barbecue rosemary after repotting?

Not immediately. Wait about 3 weeks after repotting barbecue rosemary. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
