Drastic leaf loss

Question from Mrs Carolyn French

In forum: Acacia dealbata 'Gaulois Astier'

I live in western France and bought Acacia Dealbata Gaulois from a local retailer ( not a grower, I think, more like "Wyevale" in UK ) just after Christmas, looking forward to the colour and the scent of the flowers. It's in a large, unheated enclosed verandah, with plenty of natural light, (large "French" windows along one "wall") where it should be fine, away from any frost or strong winds. So far it hasn't had to put up with much sunlight or heat this winter !!! Don't know its age - 10cms is trunk circumference where it appears above the soil and the current height at tallest shoots is 90 cms. It's been well-shaped, I feel, and has plenty of buds. Pot size is maximum 24 cms at top and the same in height. BUT in the last couple of weeks it has started and continued to shed its leaves profusely and I don't know why. They aren't really yellowed. I use rainwater for it and have watered most days because it seemed very dry when we brought it home from the garden centre. No water comes out at the bottom of the pot and it's only now that the soil at the top of the pot feels anyhow moist to the touch. Advice please, as the leaf loss is looking as though it will be desperate? Has it been left in too small a pot, perhaps to bring flower buds on, and should we re-pot it asap? Could it be a watering fault ? To reassure you about my flower care, I do have azalea, cyclamen and cymbidium all flowering well at the moment in the same room. But I don't think I'm doing very well with a "mimosa" that should be fairly tolerant. We have no intention of putting it in our small garden as there's no suitable spot. I've noticed today a slight sticky secretion where the tiny leaves join their "twig" (sorry ! I don't know the techinical terms for this ) and have no idea if this is usual with acacia or not. Thank you VERY much for reading this far and for any advice that you may be able to give me. I don't want to lose the plant !

Thank you very much for this kind reply. You have given me a second option; I'll try the reply from Essex first, and if that doesn't work out, it's the long trek from Herts to Glos for me! It'll be worth it: I have loved this tree since I was a kid (so a very long time).

Try Panglobal Plants - if Gloucestershire is any use to you. Their website is www.panglobalplants.com. This plant is on there but they don't always have the things they list in stock. The man is very helpful by email though.

I would like one of these rather hardier 'mimosas' but no-one seems to stock it. Any help gratefully received!

Re: Which is the lesser of two evils for my acacia?

In forum: Acacia dealbata 'Gaulois Astier'

Hi, Hayley,
I would say give it what it really wants when it is young to give it a healthy start. Having said that, however, the exposed aspect can be dependent upon where you live and how exposed the site truly is. Since Acacia dealbata 'Gaulois Astier'
has an H2/H3 rating, I would seriously consider an alternative if your area gets harsh winters/hard frost/freezing temps/strong winds. Or, it you really want this plant, consider giving it some serious winter protection.

In forum: Acacia dealbata

Hi, Toni,
Sounds idyllic! And also sounds like your tree is in the best place to stay protected during winter. Good the snow that was on it doesn't harm like frost does. Probably telling you something you already know, but snow actually can work to insulate plants from cold - it is the frost - the more sudden freezing that destroys cells. You definitely get colder than where I live, though I am in the foothills above Los Angeles, right next to a canyon. We, on occasion, see snow on the highest mountain peak, but that is about it. The Acacia dealbata I see is in a lovely garden in the valley and it usually blooms in January - they certainly love the climate here because it was smothered in blossoms. I've only been here two years after leaving London and I love finding out how plants behave here.
Looking forward to seeing the tree!

In forum: Acacia dealbata

Hi Kathy, I'll try and post a pic of my tree asap.

My garden is in fact an oak forest garden, and the acacia dealbata is in fact a naturalised specimen that the previous owner must have planted 50 years ago.

My tree is now about 25 years old, which is the last winter when the temperatures dropped to minus 20 Celsius and killed off all aerial growth and the tree has been growing unharmed for the last 25 years (temps do drop some winters to minus 15 Celsius). The tree grows on a sheltered south-facing slope, surrounded by oak tress. The house is just some 10 metres away, so this is in fact a kind of microclimate, I guess.

The garden is 250 metres above sea level, within a nature reserve surrounding the city of Barcelona, and we are just 10 km away from the Mediterranean Sea, in Catalonia.

My Acacia dealbata usually blooms around the first week in March (last winter, it was late March, and the tree was covered by snow for two weeks in March). This winter is being really mild, and the tree is in bloom as of early this week (6 weeks earlier than last year).

In forum: Acacia dealbata

Hi, Toni,
I just love Acacia dealbata - I am currently living in Southern California and so enjoy seeing it in bloom in January (much different than gardening in the UK in January!). I understand what you mean about hardiness ratings being a bit confusing/contradictory when your plant does something different. To have a H4 hardiness rating, however, the plant must be able to handle minimum temps down to -15C. So, where you are, it doesn't seem to get that low. Also, is your garden sheltered or is the tree near a warm house wall or garden wall? These large structures that capture warmth can create a sheltered, warmer micorclimate in the garden. Finally, seed origin and root stock origin can also make a tree somewhat hardier than other trees within the same species.
Is is possible to post a photo of your A. dealbata?

Hi, Dermod,
I hate to say it, but it doesn't sound good. Splits in the bark disrupt water and nutrient flow throughout the plant. You can try to seal them but sometimes this traps pathogens under the sealant. Any chance you could post a photo of the damage?

Acacia dealbata

Question from Dermod Malley

In forum: Trees and shrubs

Our Acacia dealbata, lovingly grown from a seed, has split in the wind due to a large lateral branch not being cut back early enough. Now there are large splits in the bark which are inclined to get mildewed. Ar there any remedies or do we just grin and bear it?

Semi Mature Tree

Message from Anna Taylor

In forum: Garden Landscaping and Design Forum Event

Hi Iris,

Thank you for your question !

Acacia dealbata is a tree native of Australia, and is relatively short lived (30 years) even in the warmer climates. You are right it is a beautiful tree, but if you don't want to risk anything fear of a gap being left, I would consider other evergreen trees.

Other fabulous evergreen trees are -

Prunus laurocerasus Latifolia (Laural) - grown as standard.

Ilex aquifolium Alaska - Classic Holly, fine to be pruned and retained at desired height and shape.

Magnolia grandiflora - a fabulous evergreen flowering tree. My favourite !

Photinia x fraseri Red Robin - great mixed red green foilage and flowers.

Ligustrum japonicum (Tree Privet) which can be kept pruned happily into a size and shape.

As the trees are evergreen, mature 4m + specimens will be expensive - the Privet will be the cheapest as it is the fastest growing.

If you would like the yellow flowers still, how about growing a summer flowering clematis like Clematis tangutica Bill Mackenzie, great to grow through trees with july to oct yellow flowers followed by seed heads !

Is the spot narrow? Could you use a more upright tree, which would create less shade or dominate the garden? Here you could plant a Laurus nobils (Bay tree).

Also could you consider that by planting closer to your house the sight line trajectory to your neighbour's window would mean that you can plant a smaller tree?

Lots of ideas - hope they help you and let me know how you get on !

looking for a semi-mature tree to screen neighbours' bedroom from our bedroom.

Question from Iris Lando

In forum: Garden Landscaping and Design Forum Event

I am considering 'Acacia dealbata' as it is beautiful and evergreen. Position is South facing and sheltered in Highgate. If I buy a specimen 4m high I am concerned that it may not have a long life. My friend's rotted and fell down after 12 yrs from a young tree. It was well protected and South too, but trunk/root ball was behind a wall. If OK, is there a specific type most beautiful? I do not want it to grow more than 5m'ish or I will prune to this so as not to shade my garden. I am 63 and screening is important straight away! (not a joke). Or...any other tree you recommend?

Beekeeping skeps

Comment from Nicola

In forum: Gardening for wildlife

Hi all - I was quite excited by the skeps (image at the bottom) I saw yesterday at Hampton Court's A Beekeepers Garden.

I have just spoken to the British Beekeepers Association about domestic use of skeps, and they have said that you can have them in your garden as a decorative addition, but if you notice a bee swarm coming into nest there, you should contact your local beekeeper right away to collect them. If you can commit to this, then it is helpful to have skeps in your garden as it will then prevent them landing in someone's roof or chimney etc. However, skeps are not suitable for cultivating honey, or allowing a permanent nest to establish in them, as they cannot be opened and inspected for diseases.

When thinking about your garden planting, blue is attractive to bees. But the BBA also said to bear in mind that bees need a large block of colour to land on and little tiny groups of plants are unlikely to really help.

The BBKA's bee friendly flowering trees are:

February: Acacia dealbata
March: Alnus cordata
April: Amelanchier lamarckii
May: Sorbus x arnoldiana
June: Sorbus aria .Tilia tomentosa
July: Castanea sativa
August: Koelreuteria paniculata
September: Tetradium daniellii

Hope this is useful!

All the best Nicola
