About Greenspire Linden

Tilia cordata 'Greenspire' · also called Greenspire Linden, Greenspire Little-Leaf Linden · flowering

Greenspire Linden is a superb street and garden tree — a cultivar of small-leaved lime selected for its strongly upright, oval crown, straight trunk, and uniform form. In midsummer it bears fragrant, nectar-rich creamy-yellow flowers adored by bees and other pollinators. One of the most widely planted urban trees in North America and Europe for its clean habit, tough constitution, and excellent air pollution tolerance.

Mature size: 12–15 m tall, 6–9 m spread

Watch for — Basal sprouts and suckers: Like many grafted or heavily pruned lindens, 'Greenspire' can produce basal shoots from below the graft union or from surface roots. Remove promptly by cutting flush at the base — do not leave stubs, which stimulate more vigorous regrowth. Keep the root zone mulched to reduce sucker frequency.

How to tell greenspire linden needs repotting

Repotting on a calendar is less reliable than reading the plant. For greenspire linden, watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and greenspire linden wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot greenspire linden

Every 2–3 years; top-dress in the in-between years. Greenspire Linden's growth habit — deciduous tree with a strongly upright, symmetrical oval crown on a straight central leader; heart-shaped cordate leaves with tufted vein axils beneath; fragrant cymose flower clusters (with bract) in july; smooth grey bark becoming ridged with age — sets the pace.

What size pot to step greenspire linden up to

Move up exactly one pot size. A heavy greenspire linden dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

The best time of year to repot greenspire linden

Early spring, just as new growth restarts, is the ideal window for greenspire linden. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting greenspire linden

Consider top-dressing first. If greenspire linden is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh moist, well-drained, fertile loam; adapts to clay or sandy loam beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave greenspire linden in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave greenspire linden in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for greenspire linden

Greenspire Linden wants moist, well-drained, fertile loam; adapts to clay or sandy loam. Performs best in deep, fertile, well-drained loam at pH 6.0–7.5. Tolerates clay soils if not waterlogged. Adapts to compacted urban soils better than many ornamental trees. Mulching the root zone greatly improves establishment in street conditions. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting greenspire linden — frequently asked questions

How often should you repot greenspire linden?

Every 2–3 years; top-dress in the in-between years for greenspire linden. Fully repot greenspire linden only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with moist, well-drained, fertile loam; adapts to clay or sandy loam. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does greenspire linden need?

When is the best time of year to repot greenspire linden?

Should you top-dress or fully repot greenspire linden?

For a big, heavy greenspire linden, top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise greenspire linden after repotting?

Not immediately. Wait about 4 weeks after repotting greenspire linden. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
