About Greig's Tulip

Tulipa greigii · also called Greig's tulip, Greigii tulip · flowering

Greig's tulip is a species tulip from Central Asia producing wide, open, bowl-shaped flowers in vivid red, orange, or yellow, often with a contrasting dark basal blotch. Its most distinctive feature is the purple-mottled or streaked foliage. Short-stemmed and reliably perennial, it is excellent for rock gardens, containers, and the front of borders. Toxic to pets.

Mature size: 15–30 cm tall, 10–15 cm spread

How to tell greig's tulip needs repotting

Repotting on a calendar is less reliable than reading the plant. For greig's tulip, 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 greig's tulip

Every 2–3 years, into bone-dry mix. Greig's Tulip's growth habit — short-stemmed, clump-forming bulbous perennial; distinctive purple-mottled or streaked broad leaves; single flower per stem, opening widely in full sun — sets the pace. Greig's tulip is a species tulip from Central Asia producing wide, open, bowl-shaped flowers in vivid red, orange, or yellow, often with a contrasting dark basal blotch. Its most distinctive feature is the purple-mottled or streaked foliage. Short-stemmed and reliably perennial, it is excellent for rock gardens, containers, and the front of borders. Toxic to pets.

What size pot to step greig's tulip up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Greig's Tulip 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 greig's tulip

Spring or summer, while greig's tulip 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 greig's tulip

Repot dry. Do not water greig's tulip 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, very 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 greig's tulip 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 greig's tulip 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 greig's tulip

Greig's Tulip wants gritty, very well-drained, neutral to alkaline soil. Thrives in rocky, stony soils with exceptional drainage — an ideal rock garden or gravel garden bulb. pH 6.5–8.0. Incorporate plenty of horticultural grit (at least 25% by volume in clay soils). Plant at 10–15 cm depth. A grit layer beneath each bulb is beneficial in heavier soils. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting greig's tulip — frequently asked questions

How often should you repot greig's tulip?

Every 2–3 years, into bone-dry mix for greig's tulip. Repot greig's tulip every 2–3 years into a snug pot of gritty, very 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 greig's tulip need?

When is the best time of year to repot greig's tulip?

Should you water greig's tulip after repotting?

No — not straight away. Repot greig's tulip 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 greig's tulip after repotting?

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