Deep planting
contact (Thu, 25 Jun 2009 22:23:05 PDT)

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
damage.
Kind greetings

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
