Growing orchids, growing future horticulturists

By Helen Roberts


Zoe Parfitt is no stranger to the University of Bristol Botanic Garden. When she was just 16 years old, Zoe did a work experience with the Garden. Now, she is the Botanic Garden's first full time trainee entirely sponsored by the Friends through their Education and Training Fund. I recently caught up with Zoe in the glasshouses to discuss her work at the Botanic Garden, her future career plans and her long-standing interest in orchids.

Zoe in Rwanda.
Zoe is a graduate of Writhlington School and was involved with the School's Orchid Project from the moment she got there at age 11 -  in fact, she still has close links with the project. During her time with the Orchid Project, Zoe not only learned a vast amount about orchids, she had opportunities to travel and share her knowledge in different countries, including South Africa, India (Sikkim) and Rwanda. Whilst in Rwanda, Zoe visited local schools to teach orchid conservation and propagation methods.

I asked Zoe if she could show me some of the orchids on display in the glasshouses - including some that were propagated at Writhlington School.

'I grow a lot of orchids at home,' explained Zoe. 'Some of which I have had a long time and are quite rare. In fact, for my interview at the Botanic Garden I took one of my favourite orchids, as I wanted to talk about it. It’s Stelis aprica, an epiphytic orchid that is quite rare with tiny flowers that are no more than 4mm in length, which are probably pollinated by gnats.'

At the Botanic Garden, Zoe looks after the orchids - watering, feeding, repotting, pollinating (which is done with a matchstick) and nurturing sick orchids back to health. She showed me several different species in the 'orchid hospital' that are currently being treated for lime scale insects.

'This is Rhynchostylisgigantea,' said Zoe, 'which I have treated by brushing on its leaves a dilute solution of methylated spirits to kill the lime scale insects. Orchids can be prone to both lime scale insects and red spider mites in the glasshouse environment. They can also be susceptible to fungal infections. It’s important when you water Cymbidium species, for example, that you water directly into the pot and not onto the plant to reduce the risk of fungal infection. Although not all orchids I have seen in the wild are a picture of health. In Sikkim, we saw orchids being eaten by slugs!'

Tips for growing orchids at home 

Zoe gave me some useful advice regarding my own orchids at home. They like to be constricted in their pots and should never be over potted. Zoe is involved in potting up any orchids and for this the media used is cork bark, sphagnum and for those that need it more moist, some perlite. It is important that orchids are fed regularly too and in the glasshouses Zoe feeds the orchids once a week in the summer and twice a week in the winter.

Zoe is currently looking after, re-potting and sorting the Bifrenaria harrisoniae, a species endemic to Brazil, display at the Garden. This species can grow as an epiphyte (living harmlessly on another plant) or as a lithophyte (living in or on rocks), and has showy flowers that are pollinated by bees and bumblebees. She hopes to propagate from a seedpod Epidendrum nocturnum, a beautiful orchid that is only fragrant in the evening and hence is pollinated by moths. Growing terrestrial orchids from seed is difficult and it can take up to 2 years for the plants to be transplanted from the micro propagation jars into growing media.

'Orchids are amazing plants, it’s a wonder they survive,' explained Zoe. 'In the seed pods there are about 2.6 million seeds, yet only 10 will survive in the wild. They rely on mycorrhizae to help them and each species will have its own particular kind.'

Looking forward

As well as the orchid duties that Zoe is responsible for, she also helps out in other parts of the garden on different projects. On the day I visited, she was helping a team get all the planting ready for transport down to the ballast seed garden barge to be planted the following day. Zoe explained that she is gaining invaluable horticultural experience at the Garden, diversifying her knowledge beyond orchid biology and horticulture.

'I am really enjoying working here. The learning and skills gained have been so helpful. I finish my traineeship in November this year and hope to go onto a career in orchid horticulture. I also want to gain my RHS level 3 award in Horticulture.'

In terms of her future career, Zoe is optimistic about her prospects in the orchid industry.

'I have been in touch with a number of different orchid growers. One in Jersey, the Eric Young Orchid Foundation, and the other is Motes Orchids based in Florida. I hope to secure work at these well-known orchid nurseries. In the next few years I would love to do more orchid hunting, but this time in Central America with the long term career goal to eventually set up and teach projects in orchid conservation.'


Zoe currently writes a number of orchid articles for various publications and these include The Cheltenham & District Orchid Society and Orchid Review. She has also spoken at and attended the World Orchid Congress (funded by The Cheltenham & District Orchid Society) in South Africa and attended the European Orchid Congress in London and taken part in many different orchid and flower shows including Hampton Court Flower Show where MontyDon interviewed her.

Christmas and the Botanic Garden

Being out and about in the Garden gives a sense of the changing of the seasons, a sense brought about by the combination of light, temperature, wildlife and, of course, plants. This is felt most keenly at this time when we are the furthest from the sun that we will be, until next year. I find mid-winter an uplifting time; leafless trees show their bones and wildlife is easier to spot. It’s amazing how much life is flitting around in an old oak tree when you take the time to look into its branches. The sky seems bigger in winter and the sunsets more vivid. This might just be that we don’t get to see them so much in midsummer, but at this time of year we see the sun rise in the Garden and set in the Garden.
From this moment the days get a little longer and we begin to see movement in the soil, small signposts to spring that don’t occur before midwinter. Snowdrops and winter aconite emerge in January; tiny and fragrant flowers emerge on shrubs such as witch-hazel, Daphne, winter flowerin…

In the guts of bees

By Nicola Temple We hear a great deal about the beneficial bacteria that live in our digestive system and commonly referred to as the microbiome, which help us turn indigestible materials into nutrients that we can absorb. There are countless probiotic products on the market that are meant to introduce more of these beneficial bacteria into our system, enriching our microbiome. However, humans and indeed mammals are not alone in having helpful microflora in the gut.

The microbes that inhabit the guts of social bees has been of particular interest recently. These microbial communities have been studied for their role in bee health, but also as a model organism to help understand the relationship between hosts and their gut microbes, potentially providing insight into our own system.

The specialised cast of microbes The microbiome of bees is relatively simple, but very specialised. There are about eight to ten bacterial species, but different species of bee will carry different strai…

Why doesn't everyone compost?

By Alida Robey
Composting was an inherent part of how we lived when I was growing up – nothing was wasted.  Food scraps went to the chickens, kitchen and garden waste to one of several  compost heaps and leaves were piled into a pit for future leaf-mould.
Today,  I live in a flat with a small decked courtyard. I have access to five compost bins in an area of communal gardens in Clifton (Bristol, UK); this means with almost no effort at all the only rubbish I produce is recycling and an occasional black bag of non-recycleable inorganic waste. I don't even have to keep a compost bin at home. And still each week along my road I see quantities of black bags destined for landfill spilling out onto the pavement with fruit and veg and greenery.  Given the years I have spent trying to coax friends and neighbours in different locations to compost, this scene is a heart-rending weekly reminder of my lack of success in this personal campaign!
So when I was camping a few weeks ago, and had r…
