New slabs around willow tree, leaves going yellow
I have a 20 yr old American purple stem willow tree it is not very big, about 9 or 10 foot tall and about 9ft diametre. Apparently they stay fairly small. Its leaves have started to go yellow, not sure if its because of the new slabbing around it or that it will be getting less water or if its normal for the leaves to go yellow at this time of year
I have just had the area slabbed around it to extend the patio and while this was being done some of the roots (I'm pressuming it was the roots from the willow) were chopped off as the area was dug to about 5 or 6 inches before the slabs were laid so it has lost 5 or 6 inches of top soil over a 15ft by 15ft area. The gaps between the slabs have been filled in and under them will now be the sand and cement mixture which was put in all the corners so there will be gaps under there too with no soil. I don't really want to lose it, next to the trunk there has been left quite a small area about 18 inch square which has been filled with soil. Could it be that it has to recover from the roots being chopped a bit or will it be lack of water? I thought with it being there for 20 years that it might withstand it as its root system was well established. Will it recover? |

If it is just root damage due to the digging it will recover during its dormant period this winter, if it is objecting to the sudden increase in PH then its recovery may take longer. It may of course just have been the dry year to date. but whatever, sit on your hands and do nothing (apart from water if you think it could be very dry) See what happens in spring before deciding what to do -- Charlie Pridham, Gardening in Cornwall ROSELAND HOUSE GARDEN & NURSERY Holders of national collections of Clematis viticella cultivars and Lapageria rosea[/quote] Yes I thought about the cement affecting it too. I have just watered it in the small soil area around the trunk and watered the leaves then I gave it 1.5 gallons of tomato feed as it had nitrogen in it. I'm thinking of taking the soil out of the trunk area so more water can get below the slabs as there are gaps under them. I'm then going to put some granite stones to replace the soil that wont fall into the gaps under the slabs. I could from time to time push the hose pipe under the slabs to get water further under there. Would it help to trim the tree a bit seeing as its water has been greatly reduced? |

I don't know this species in particular, but willows in general do have great powers of recovery, but I think the filling between the slabs, if it's mortar, needs to come out to admit not only water, but air. Any possibility of making that slab-free patch a bit wider? -- Mike. |

Its sand and cement mixture and there are some gaps under the slabs as it was put in the 4 corners of each slab leaving gaps between but none the less theres a lot of it under there now. So if I remove the soil from the square some air. would get in and some water. It would be hard to make the square wider now but I'll just see how it goes for a while and keep putting the hose under to try and get to recover a bit of strength first and decide wht to do depending on what happens |
