About Hairy Jovibarba

Jovibarba hirta · also called Hairy Jovibarba, Hairy Houseleek · houseplant

Jovibarba hirta is an alpine succulent from the eastern European mountains, distinguished by its noticeably hairy or ciliate leaf margins. It forms tight, attractive rosettes that offset freely, tolerating severe cold, poor soils, and drought. Perfect for rock gardens, alpine troughs, and sunny indoor windowsills, it needs almost no attention beyond good drainage.

Mature size: Rosettes 3–7 cm across; mats spreading to 20–40 cm

Watch for — Etiolation in low light: Without sufficient direct sun the rosettes lose their compactness and the hairs become less pronounced. Move to brighter exposure; there is no way to reverse existing stretched growth, but new growth will improve.

How to tell hairy jovibarba needs repotting

Repotting on a calendar is less reliable than reading the plant. For hairy jovibarba, 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 hairy jovibarba

Every 2–3 years, into bone-dry mix. Hairy Jovibarba's growth habit — clump-forming rosette succulent; offsets freely around the base of the mother rosette, forming dense mats over time — sets the pace. Jovibarba hirta is an alpine succulent from the eastern European mountains, distinguished by its noticeably hairy or ciliate leaf margins. It forms tight, attractive rosettes that offset freely, tolerating severe cold, poor soils, and drought. Perfect for rock gardens, alpine troughs, and sunny indoor windowsills, it needs almost no attention beyond good drainage.

What size pot to step hairy jovibarba up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Hairy Jovibarba 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.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot hairy jovibarba

Spring or summer, while hairy jovibarba 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 hairy jovibarba

Repot dry. Do not water hairy jovibarba 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 lean, gritty, extremely well-draining mix 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 hairy jovibarba 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 hairy jovibarba 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 hairy jovibarba

Hairy Jovibarba wants lean, gritty, extremely well-draining mix. A 50:50 mix of coarse horticultural grit and loam-based compost is ideal. Avoid any peat, coir, or other moisture-retaining amendments. Top-dress with grit to keep the collar dry. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting hairy jovibarba — frequently asked questions

How often should you repot hairy jovibarba?

Every 2–3 years, into bone-dry mix for hairy jovibarba. Repot hairy jovibarba every 2–3 years into a snug pot of lean, gritty, extremely well-draining mix, 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 hairy jovibarba need?

When is the best time of year to repot hairy jovibarba?

Should you water hairy jovibarba after repotting?

No — not straight away. Repot hairy jovibarba 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 hairy jovibarba after repotting?

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