When should I plant tulips?

November to early December — later than other spring bulbs. Two reasons: (1) cold autumn soil suppresses tulip fire disease (Botrytis tulipae), which thrives in warm September–October soil; (2) tulips don't need an early start for spring flowering. Plant 10–15 cm deep (deeper than usually advised — 15–20 cm gives better perennialisation and protects from squirrels). In Scotland and the north: late October is fine because soil is cooler by then.

Why don't my tulips come back the next year?

Most likely two causes. (1) Dutch hybrid tulips are short-lived in UK gardens — most named cultivars flower brilliantly year 1, weakly year 2, disappear by year 3. Solution: plant Darwin hybrids (Apeldoorn, Pink Impression) or species tulips, which perennialise reliably. (2) Planted too shallow — at 5–8 cm depth bulbs split into many small non-flowering offsets rather than one large bulb. Plant 15–20 cm deep. (3) Foliage cut too early — leaves need 6+ weeks after flowering to refill the bulb.

How deep should I plant tulip bulbs?

Deeper than usually advised — 15–20 cm. Standard advice (10 cm) often leads to bulbs that split into many small non-flowering offsets and disappear within 2–3 years. Deeper planting (15–20 cm) keeps bulbs intact and producing flowering-sized growth year after year. Bonus benefit: deeper bulbs are out of squirrel reach. For species tulips: 10 cm is fine (smaller bulbs, shallower naturally).

Will tulips naturalise in my lawn?

Mostly no — but species tulips will. Dutch hybrid tulips rarely naturalise in lawns — they need lifting, drying, and replanting to perform reliably, which is incompatible with lawn cultivation. Species tulips (T. tarda, T. clusiana, T. saxatilis) do naturalise into drifts in well-drained sunny lawns, similar to crocuses but slower. For naturalising: species tulips at 10 cm depth, in sunny meadow-style lawns, don't mow until mid-June.

What's the best tulip variety for the UK?

For perennial return: Darwin hybrid tulips (Apeldoorn red, Pink Impression, Daydream) — the most reliable repeat-flowerers among the large Dutch types. For naturalising: species tulips like T. tarda (yellow with white margins, multi-headed), T. clusiana (Lady Tulip, pink-and-white), or T. turkestanica (white with yellow centres, very early). For impact (treated as annuals): any Dutch hybrid in mass planting. For pots: dwarf species tulips, T. greigii hybrids, T. kaufmanniana hybrids.

Can I grow tulips in pots?

Yes — pots showcase tulips brilliantly. Use a 30 cm pot of peat-free compost with grit for drainage. Plant 10–15 bulbs in November, 10 cm deep. Move pots under cover in deep winter if hard frost is forecast (especially clay pots which can crack); bring out for flower display in spring. After flowering: most pot tulips are best treated as annuals (compost the bulbs after foliage dies back); or plant exhausted bulbs in the garden border for them to try again next year.

Tulipa

Piantate i bulbi di tulipano tra novembre e l'inizio di dicembre (più tardi rispetto agli altri bulbi primaverili): il terreno freddo riduce il rischio di "tulip fire" (malattia del fuoco del tulipano); una semina precoce nel terreno autunnale caldo favorisce invece questa malattia fungina. I tulipani sono resistenti al freddo (RHS H6) e rappresentano i bulbi primaverili più vari, con migliaia di cultivar che spaziano dalle specie nane alle eleganti varietà a fiore di giglio, fino alle sgargianti varietà doppie e "parrot". La maggior parte dei tulipani ibridi olandesi ha vita breve nei giardini del Regno Unito: fioriscono splendidamente il primo anno, debolmente il secondo e spesso scompaiono entro il terzo (estrateli, conservateli e ripiantateli per una fioritura ripetuta affidabile, OPPURE trattateli come annuali). I tulipani selvatici e gli ibridi di Darwin sono le eccezioni: questi diventano perenni e si naturalizzano. Piantateli a 10-15 cm di profondità in un terreno ben drenato e in pieno sole. Gli scoiattoli mangiano i bulbi di tulipano: proteggeteli piantandoli in profondità e utilizzando una rete metallica.
