Tree pit knowledge anybody?

[Dr.Green]

been asked to do a job of remove some trees on a development site and then replant new stick elsewhere inc treepits .

 

apart form removal / replant which is no problem anybody got any information on treepits ??? these are for small trees ..

 

by the sounds of it a tree pit is just a hole (dont fancy digging with a spade) to plant them in and filled with the relivant soil mix which has been specified, or is the tree pit a contained area to stop root growth outside of an area???

 

thanks , any help or input whatever it may be is always usfull:thumbup1:

 

here is the spec

=====

minimum depth throughout.

- Pit bottoms: With slightly raised centre. Break up to a depth of 150mm.

- Treatment: Soil ameliorant worked into pit bottoms.

I while ago I posted an image on pit planting, it's in a thread some where, I'll see if I can find it

That is a standard pit discription to give the planted tree the best start in its new location.

 

Otherwise know as a whole in the ground with rough edges.

there is a danger in improving the soil in the pit too much, it encourages roots to stay in the pit rather than push out to explore, girdling worst cases.

excellant as i was thinking of a contained tree pit which if im honest at short notice cant quote for the work if that was the case . however '''Otherwise know as a whole in the ground with rough edges.'' sounds nice enough for me today

i did think this also , but if its in the spec and i follow it and cant be held responsible , but on the other hand maybe i should advise of this when i submit my quote:001_smile:

I would want to know the soil type before making amendment specs, if your offering advice, base it on the soil dont just wing it.

If you are not sure dig a small test pit, and test the soil with a test kit(that can be bought cheaply from a garen center). This will quickly tell you wether their discription is correct or not.

il keep it simple and stick to the spec - from what i believe they have given me a spec on pits and the tree species and i am the boy to do the 'dirty' work as all previous inspections and tests have been made.

 

one last thing , cant find any information on this

I reckon there is a big question mark over fertilizing trees. Specifying slow release fertilizer and broadleaf p4 may give fantastic short term results but will the long term outlook for the tree benefit from this?
