On Saturday, the students who completed the 2018 Spring course of the Certificate of Practical Horticulture were awarded their certificates in the South Wing of the Kibble Palace. A special award was also made by the Baldernock Gardening Club to the ‘most improved’ student. The recipient was Karen, a student who traveled down every day from Aberdeen to attend the course and is determined to pursue a career in horticulture. Well done to everyone, and thanks to lead tutor Paul (far right) and assistant tutor Lisa (far left) for making the course as successful and friendly as usual.
On the 31st of August, as we slowly slip into Autumn, why not come along to the Bat and Moth Night at Glasgow Botanic Gardens.
Meet near the Kibble Palace after 7.00pm for a 7.30 pm start.
Please contact Scott Donaldson at firstname.lastname@example.org to book your place.
I know its technically Fagus sylvatica, but it’s a tricky business getting a funny title out of a scientific bi-nomial.
What’s not funny was the poor treatment that the 250 year old Pollok Beech received about one year ago.
As reported in many papers the Wishing Tree, which featured in Scotland’s 100 Heritage Tree list, was burned out by vandals and despite the best efforts of Pollok staff, Countryside Rangers and Scottish Fire and Rescue the damage was so great the tree split in two.
The tree continues to produce some sparse lateral growth and it’s been decided that now is the time of year to attempt some cuttings.
Led by Stevie Jacusz , Botanic’s propagator extraordinaire, an attempt will be made to root about twenty hardwood cuttings just before bud break.
Normally grown from seed, or in the case of coloured or cultivars with unusual form, from grafted material , growing Fagus sylvatica from hardwood cuttings usually has a very poor outcome. The cuttings are slow to root and then very prone to rotting after their fist winter, probably because the root system has not become fully established.
Day one of the mission 07/04/2018
We were hoping to take hard wood cuttings from both sides of the split trunk just at bud break so timing was everything.
On the side nearest the steps the buds are swollen and ready to go.
But at the other side the wood is brittle, no new buds are present and dead leaves still hang from the twigs. Unfortunately, not a good sign. Pretty much a rescue mission now.
Secateurs ..check, old compost bag….check….twenty cuttings,
We understand the significance this tree has to many people that visit Pollok Park, so we were very careful not to move or cut any twigs or branches that had messages or wishes attached.
We popped them into the tree ambulance and raced (at an appropriate speed for the conditions and with due care) back to Glasgow Botanics.
After soaking the material, Stevie is going to strip the buds and create 12 inch basal cuttings and also try some apical cuttings for luck.
The cuttings are wounded at the base and then dipped into hormone powder to promote rooting.
We are using a fairly loose coir based compost to attempt to root the cuttings, a few secret ingredients are added.
The details are stored in the Botanic Garden database and a new label and barcode are produced.
The cuttings are placed round the outside of the pot where there is better compost aeration and where its slightly warmer to promote root growth, it also gives us the maximum space per cutting per pot.
8 pots, with about 6 cuttings a pot, are placed into the outside frames.
Aljos Farjon ,the Kew Botanic Gardens tree specialist, mentioned in his talk to the Friends of Glasgow Botanic Gardens (November 2017) that burning/vandalism was one of the major threats to our Heritage Trees in urban areas. many councils have taken to caging and boarding up ancient oaks.
48 cuttings in total, we just need one to take.
A possible outcome of this rescue mission could be the donation of a new generation of Pollok Wishing Trees to local parks, schools and gardens.
We will keep this section updated as we go through the next few years.
Wee Hamish McDiddy, from just outside Liverpool, has sent in a request for ash related postings, it was wrapped in two pieces of bread and jam.
Our tree, appropriately the weeping ash, was a gift to the original Glasgow Botanic Gardens (at Sandyford, near Sauchiehall Street) from nurseryman, Robert Austin. Having been planted in 1818 it was then moved to its current site in 1841. The original tree was small so all the taller trees were grafted high up to produce a tall, clear trunk with upper pendulous branches. All the ‘Pendula’ cultivars are believed to descend from a single tree found in the parish of Gamlingay, Cambridgeshire.

Alas, more research now needed….
Sunrise on the first day of Spring.
It wasn’t the usual journey to work today!
We were a bit dismissive of the snow yesterday but overnight we received a sharp reminder from Mother Nature in the form of just less than a foot of snow at Glasgow Botanics.
The Tea Room staff have walked several miles from the south of Glasgow to open up the Curators House Tea Room. I think they were needing a drop of their own medicine by the time they arrived.
Usually home to ‘cool’ events such as the Book Fair, Botanical Painting or Garden Design classes the Hopkirk Building is looking slightly chilly today. Please contact your course lead before traveling, if you plan to attend any classes over the next two days.
Due to difficulties with the transport network, we are short staffed at the moment so the Main Range will remain shut, the Kibble Palace, as always, is open till 4. Inside the glasshouses the plants still need watered despite the snow and we would like to thank our Glasgow University student placement who turned up today and assisted two of the horticultural apprentices with glasshouse maintenance.
Today ( 1/03/2018), the Main Range will remain shut, Public Toilets are open till 4 pm, The Tea Room is open but will close at 2pm, Kibble will close at 4 pm and we will be shutting and locking the gates to the grounds by 5pm.
We were open this morning, as we have been for nearly 201 years, despite the ‘dusting of snow’. To ensure staff and public are cleared from the grounds safely, glasshouses and grounds will close earlier than advertised.
Main Range Glasshouses will close at 13.30
Kibble Palace will close at 15.30
Grounds will start to close from 16.00
We will open again hopefully as normal tomorrow.
Sorry to disappoint the Galanthophiles with the post title.
Despite the continuing chilly weather, work is continuing around the garden. Find out what has been going on here.
A lot of new work is getting under way at GBG. Plans are being prepared for a change in the North American Arid House (Main Range 5) and the team are preparing planting pits for new trees and shrubs to be planted in the grounds. It’s still cold outside but under glass there is still a lot to see here is a quick look at an interesting plant currently flowering in the palm house.
After a lot of hard work by the team at GBG the infected Rhododendrons at the Main Entrance have been removed or destroyed on-site. After the plants directly within the quarantined area and associated leaf litter were destroyed, approximately one month ago, the plants outwith the quarantined zone have had the top growth removed and burned. The rootballs of these plants will be removed and disposed of off-site as quickly as possible.
The beds were quite overgrown, some plants were leggy and had been damaged over the years but the Rhododendrons still provided early seasonal colour. Speaking to some of the frequent visitors to GBG these plants will be greatly missed.
In October the scene looked like this;
The squad are just finishing with stage 2 of the clearance today, 30th of November;
We will be working with partners in the Plant Health Unit of the Scottish Government to continue to monitor and review the situation with regards to Phytophthora at GBG.
We are restricted for 4 years in our planting choice for these beds but we shall publish our new plans soon.
Update on the P. ramorum outbreak.
We have now removed the plants that were identified, by laboratory testing, as being infected with the pathogen.
We feel it is prudent to remove all the susceptible species from the two planting beds and work to complete this task is now ongoing.
Original Post 19/10/2017
Glasgow Botanic Gardens takes matters surrounding Plant Health and Biosecurity very seriously and co-operates closely with other partner agencies to maintain good standards and best practice.
A recent monitoring visit by the Scottish Government’s Plant Health Unit identified a possible problem with some of the Rhododendron plants in the garden.
Laboratory results have now identified a pathogen called Phytophthora ramorum on Rhododendron in two beds in the garden.
We have listed some Frequently Asked Questions below;
What is the disease?
Phytophthora ramorum (P. ramorum) is a fungus-like pathogen called a water mould. It causes extensive damage and death to a wide range of trees and other plants.
The generic name for the disease which it causes is Ramorum disease. The disease is known in the USA as ‘sudden oak death’ because different genetic forms of the P. ramorum organism from those present in the UK have caused significant damage to North American native oak and tanoak species. However, the genetic forms of the P. ramorum organism found in the United Kingdom have had little effect on Britain’s two native oak species: pedunculate or ‘English’ oak and sessile oak (Quercus robur and Q. petraea respectively).
Will the disease make me or my pet ill?
Phytophthora ramorum is not a risk to human or animal health but does pose a threat to a large number of plants within the Botanic Gardens Collections.
How did it get here?
The plants that are infected are mature and were planted twenty years ago so it’s not a disease that has been brought in from a horticultural nursery.
The disease is spread in water-splash, often near pathways, where infected material from footwear, paws or tyre tread comes into contact with the leaves of a susceptible host. Given the location of the infection on plants in Glasgow Botanic Gardens, this has been the probable cause.
What will happen now?
A Plant Health Order has been issued and the Botanic Gardens will now take immediate steps to remove and destroy the infected plants and other host plants in the immediate vicinity. A ban will be put in place on certain plants being moved from the gardens. We will not be replanting the areas with species that are susceptible to P. ramorum.
Plant Health Inspections will continue until we receive an all clear notice.
How can I help?
You can help by;
~ Cleaning footwear, wheels, paws, etc. after other visiting sites such as gardens, country parks and plantation forestry.
~ Keeping to paths, not walking on borders or entering any cordoned-off areas
~ Not removing plant material from the site
~ Keeping dogs on short leads
~ Keeping well informed and using sources of further information (books, websites etc.) on pests and diseases and their control in your own garden!
