Da steht ein Lindenbaum

[Leanne]

Hello Eileen, how lovely to see you back! There is a wonderful connectedness to this poem, such that it works as either a human or divine gardener, or indeed the earth itself shifting with the seasons. The intertextuality adds depth (and music, at least in my head).

Da steht ein Lindenbaum

A rough sort of love for life;
a love which shivers and shakes off -- it probably doesn't make much difference, but I think 'that' is better than 'which' here
blankets, patchwork quilts of leaves. -- 'patchwork quilts of leaves' is edging toward cliche

The love of twigs, snapping -- slight clausal confusion (because I'm nerdy) suggests to me that an em-dash might work better than a comma on this line and perhaps as an alternative to the semi-colon on the next line
underfoot, between finger and thumb;
bark on soft palms and rivulets of sap. -- this reads as though the bark is on the rivulets of sap also, whereas I think your intent is that the rivulets of sap are on the palms

I have been digging; densely packing
earth beneath nails. Cementing up
gaps of self, building my limbs anew. -- all the -ings work quite nicely here

Lips cracked; caked, clayed, and cloyed. -- lovely alliteration!
Hands clasped at the root: a prayer, -- slight grammatical issue here -- sounds like the hands are clasped at the root of the hands, because no other root has been introduced (and my hands don't have roots so I'm sure that's not what you mean!)
half-sung, murmured. Held for just a breath.
