Paw Paw Fruit Trees

 

2010-02-05 10-26-42 Paw Paw leaf intricate patterns - IMG_1565

 

I never thought about growing exotic fruit like the Paw Paw That was until I saw a tree for sale in Thompson Morgan’s catalogue. The sun accentuates the intricate pattern in this paw paw leaf.

Asimina triloba Papaw or North American Paw Paw

  • This hardy pawpaw produces solitary, cup-shaped flowers and large, exotic foliage.
  • During long, hot summers it will produce edible fruits with a delicious, tropical flavour, that can be harvested from September.
  • In cool climates the Paw paw or Red Indian Banana forms an attractive multi-stemmed plant that makes an unusual addition to the shrub border with its buttery yellow autumn foliage.
  • Pawpaws are self fertile, and pollinated by insects, however the chances of pollination will improve when growing more than one paw paw.
  • Alternatively the flowers can be hand pollinated.
  • Height and spread to 19’ so they do need a spacious garden.
  • Happiest in full sun or dappled shade

Asimina Triloba / Paw Paw

 

‘Pawpaw (Asimina) is a genus of small clustered trees with large leaves and fruit. Growth Habit: The pawpaw is a deciduous, often narrowly conical tree growing from about 12 feet to around 20 feet. Pawpaw trees are prone to producing root suckers a few feet from the trunk. When these are permitted to grow, the single-clone pawpaw patch comes into being. The prevailing experiences of many individuals is that the pawpaw is a slow grower, particularly when it is young. However, under optimal greenhouse conditions, including photo-period extension light of approximately 16 hours, top growth of up to 5 feet can be attained in three months. Continue Reading →

Firethorn or Pyracantha For Berries

Snape pyracantha

Pyracantha, can be a neat shrub with attractive flowers and magnificent red, yellow or orange berries. The white flowers in summer are followed by autumn and winter berries, in fact my shrubs are still in berry this March.

Growing Tips

  • Train  your Pyracantha against a wall or fence or as a specimen plant.
  • Clipped regularly Firethorn, or Pyracantha as it is correctly known, also makes an excellent evergreen hedge.
  • Plants will grow in most fertile garden soil  in sun or partial shade.
  • Avoid  water-logging but if near a wall or hedge water your plants in dry spells.
  • Berrying may be reduced in shady sites or against north-facing walls.
  • Plants grow 5-10 feet high and wide if unrestricted.
  • A general purpose spring feed and mulch is welcome.
  • Propagate from cuttings or seed that may not come true to the parent plant.

 

Pruning and Clipping

  • Pyracantha flowers on shoots produced the previous year so avoid trimming off too many flowers. Try to retain as much two-year-old wood as possible.
  • Pyracantha has long, sharp thorns hence it’s common name Firethorn. It can be used in a hedge to deter unwanted visitors
  • When overgrown, Pyracantha can be heavily pruned  to get back into shape.
  • Prune to make the berries more visible and to keep the plants in shape.
  • Shorten all sideshoots that grow from the main framework in late summer. Stop just short of the clusters of berries   about two to three leaves from the base of the side shoot.
  • While young shoots are still flexible so tie them in or train to form shapes.
  • Trim Pyracantha hedges a couple of times between spring and the end of summer

Poplar Roundabout Felled in Sep-timber

In an oval roundabout in Menston a dozen Poplar trees were planted in the 1970s. As you can see only about half survive and these have been mistreated by polling them to restrict height.

What you may want to know about Poplars

  • Poplars (Populus)  are rapidly growing trees with shallow, spreading roots. Do not plant them near buildings.
  • The Black Poplar (nigra) has a shortish life of around 30 years so I shouldn’t be surprised by the state of these trees.
  • White Poplars (alba) are suckering trees with white woolly undersides to the leaf.
  • Balsam poplars can grow 6 feet per year and have a balsamic scent.
  • Female trees have long catkins but they are too high up these trees to see.

Poplar trees are usually felled in Sep-timber!

Cloak a wall in Jasmine

This Winter Jasmine or Jasminum Nudiflorum is just flowering on a neighbours, southwest facing, brick wall. Flowering a bit earlier this year it should flower through to March. The result shown is as a result of regular pruning and the stems have been tied in.

  • Left to it own devices the winter jasmine will form a 2 foot high mound as it won’t twine and is unable to climb unaided.
  • Cuttings from the arching stems can be taken in early summer.
  • Although deciduous the young stems are green and the flowers are born on bare stems giving the overall impression of an evergreen.
  • Unlike indoor Jasmine this plant has little or no fragrance
  • The AGM has been awarded to Jasminum Nudiflorum and it also has an apt Chinese name ‘Welcoming Spring Flower’

Uses for Crab Apples

Crab apples can be used as food, for ornamental effect, to help pollination, or for the wood. The wild crab apple found individually in woods has green fruit turning golden in Autumn. Cultivated crab apples vary in habit and grow upto 10 feet. Fruiting this year looks like a bumper harvest after the wet weather earlier in the year.

Crab Apples make attractive ornamental trees with their pink or white blossom, followed by colourful autumn fruits that make delicious preserves. Varieties John Downie, Golden Hornet, Laura and Red Sentinel are all self fertile. Crab apples planted near fruiting apple trees make excellent pollinators and will help pollinating bees to increase your crops.

Crab apples are used to make jelly, pickles or can be roasted and served with meat or added to winter ale or cider. Any unpicked fruits will soften after a few frosts and will create a sumptuous food source for wild birds from late January until March. For a jelly recipe with a chillie kick try Cottage Smallholder

The timber of the crab apple is uniform in texture and if dried slowly, is excellent for woodworking. At one time it was used for making set-squares and other drawing instruments. Failing that apple wood burns in your chimenea of fire grate with a nice aroma.

Strange and Attractive Autumn Shrubs

It is worth inspecting closely the plants that have waited all year to bloom or display special features.

This purple and white flower combination was covering an 8 foot high and wide bushy shrub at Thorp Perrow. It was catalogued as ‘Clerodendron trichotomum’. I have managed to kill my own Clerodendron so I was happy to see a large sweetly scented plant in such robust health. The white flowers and maroon calyces will be followed by blue berries for which the plant gets its Autumn plaudits. I would recommend this variety rather than Clerodendron bungei which is less gainly and has feotid leaves.

I am trying to work out what this shapely shrub with the long blue pods is called. Any ideas?

Cornus Kausa ‘Gold Star’ is a variety to look out for with the variegated foliage and the red seed pods in Autumn.
