I always understood decorations should come down on Epiphany (6 Jan). I still have a couple of things to put away today. I love the decorations and the decorating but also really like that clean tidy feeling in January when you pack it all away. We took our LED icicle lights camping (we have a battery pack thing) when our teenage twin girls wanted a camping birthday sleep over with their friends, made for a very pretty birthday camp site and did not attract insects which was a definite bonus

We had a similar experience about 30 years ago. Along with that same pine tree we had a huge full blue spruce right next to it in front of our house. Both trees were full with branches right to the ground, healthy & beautiful. It made our house disappear & look like a matchbox house & prevented light to come in. Both were 75' tall & growing nonstop. It started to affect our pipes. I don't like cutting down healthy trees. I began calling some large landscape companies asking them if they'd take them. One company had a customer who wanted live trees as a fence & barrier in an expensive suburb near Boston. They gave me a price & thought it was fair. We were really happy they wouldn't be destroyed. What a day it was when they came to remove those trees! Neighbors came over & cars driving by pulled over to watch. It was fascinating how a huge machine fit around the tree & lifted it up, roots impact & no damage at all. It took two days & the landscaper handed us a check which paid for filling those very large & deep holes. IMO I'd leave the tree for the new owners to decide whether to remove it or not. It's not that uncommon as you'd think.

That looks like an odd shaped, narrow angled back corner of the yard. Previously the big peppercorn tree filled it out, softened it and it looks like a cubby house enjoyed the cosy, secret corner behind the natural screen. One idea would be: firstly, get a stump grinder in to remove the stump which will otherwise limit any planting; secondly, plant a curved hedge of a suitable shrub (Murraya, bottlebrush, lilypilli...). Leave an opening at one or both ends of the hedge screen for access to the "secret corner". This might improve the shape of the yard and provide a useful utility area for compost bins, a small garden shed or other unsightly items.

I would not be inclined to plant a Murraya for your hedge. I have a Murraya hedge and am forever clipping it. The branches also become a bit thick to trim. The Indian Hawthorne pictured is in my opinion a more suitable plant. It flowers most of the year and is easy to keep in shape or can be left to grow naturally. It comes in whit or different shades of pink. The pink variety is a slower grower therefore less clipping. Go and have a look at the nursery to see if you like the foliage and flowers. I agree with the comment, not to try to keep the pines which somebody else has planted. This is your home now and you have the opportunity to design the garden. Good luck with your new garden. Jan
