About Tilia tomentosa 'Petiolaris'
Tilia tomentosa 'Petiolaris' · also called Weeping Silver Lime, Pendent Silver Lime · flowering
The weeping silver lime is an elegant large deciduous tree with arching, pendulous branches and dark leaves backed in silvery-white felt that shimmer in the breeze. Its richly scented late-summer flowers draw pollinators. Tolerant of pollution and heat, it makes a stately specimen. Tilia is ASPCA-listed as non-toxic to dogs and cats.
Preferred mix: Fertile, moist, well-drained loam
Watch for — Leaf scorch in extreme heat: Despite good heat tolerance, foliage can brown at the margins in prolonged drought on shallow soil. Mulch and water young trees; mature specimens normally shrug it off.
Why tilia tomentosa 'petiolaris' needs this mix
Tilia tomentosa 'Petiolaris' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Tilia tomentosa 'Petiolaris' evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons tilia tomentosa 'petiolaris' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of tilia tomentosa 'petiolaris' — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing tilia tomentosa 'petiolaris' in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for tilia tomentosa 'petiolaris'?
Tilia tomentosa 'Petiolaris' likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "herb" or "Mediterranean" mixes are usually fine for tilia tomentosa 'petiolaris', but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so tilia tomentosa 'petiolaris' needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for tilia tomentosa 'petiolaris' covers the timing and technique step by step.
