Deep planting

Dear all,
Just to confirm  Jane's remarks It is one of the most eficient way to avoid 
'tunneling rodents'.  Thee many  species  which prefer planting at a depth 
of 20-25cm (8-10") Tunneling occurs at the depth of 10-15cm (4-6") sometimes 
they  cut the stem without harming the bulb.  For technical reasons  a 
commercial nursery cannot plant that deep, but in permanent garden situation 
deep planting is a good solution. According to my observations in the 
nursery this applies especially to Tulips (esp T.sylvestris), Narcissus, 
Moraea (esp M simulans), Leopoldia comosa,  Odontoglossum, Leucocoryne, 
Crocus, Tropeaolum, Rhodophiala, Triteleia,  Sternbergia. 
 Planting on the surface (par example Cyclamen) also avoids this rodent

It's remarkable how deep bulbs will "pull down," 

left to their own devices, even in stiff soil. Sometimes this allows 

them to avoid tunneling rodents as well as winter cold. I've noticed 

that themids (Triteleia, Brodiaea, etc.) have much more robust
