Trees/Shrubs Winter Care


 
Hi all,
 
I would appreciate some advice.  I am helping my new neighbour tidy up her garden.  We have had the coldest Winter for past 20 years, with a number of storms and very high winds so many plants are not looking their best.
 
And to my queries:
  • Poinsettia (Euphorbia pulcherrima) - due to the bad weather the flowers and leaves have been shredded so naturally does not look good.  I believe that it is best to delay pruning until April or so.  Can I prune now and by how much?  Branching starts about at about 3ft on main trunk.
  • Pentas - They have just finished flowering.  They are about 2ft tall.  Do I prune and by how much.?
  • Rudbeckia (I think) - about 6ft tall and lanky.  It had maybe 30 buds in October but only 6 flowered.  Maybe it is not so drought tolerant and needs regular watering which it didn't get in the Autumn.  It has some seed heads but otherwise is not attractive.  When do I prune back?
  • Tidying up the fruit trees in the lower garden, I discovered that a lemon tree has been planted still in its plastic pot!!.  The tree is not looking too bright.  Should I try digging up the plant completely and remove the plastic pot, or dig around the sides of the plastic pot leaving the tree in situ and then try and remove the plastic or leave it as it is? 
  • Also my neighbours would like to plant some more fruit trees in a low maintenance lawn (gramma) with irrigation.  They already have fig, apricot and grapefruit growing in this lawn so any other suggestions apart the previously named and loquat which they don't like would be welcome.
  • Chorisia speciosa -  a young tree is not doing well.  All the top branches have rotted back to main trunk.  Should it be pruned back to good wood and how will the tree look in the future with no central branch provided the tree recovers of course?
  • Livistona palms (young) planted out in full sun have yellowish leaves.  A deficiency in magnesium or iron or ?
I am sorry that I only seem to contribute when I require advice but I enjoy reading all your posts.  Many thanks,
