Spring is here – we all love to notice signs of renewal of the season – but when exactly is the start of Spring?
There are three different measures we can use:
Meteorological – fixed every year to ensure statistics are consistent throughout time. Spring in the northern hemisphere starts on 1 March and autumn on 1 September. Dates have been decided using temperature data.
Astronomical – follows the equinox and can vary slightly each year. Spring falls between 19-23 March and autumn 22-24 September. In 2025 astronomical Spring begins on the 20th March
Phenological – follows biological events and their response to weather and climate. This is a fascinating study which shows how nature reacts to changes in climate. Nature’s Calendar uses public sightings of plants, animals and fungi to track the effects of weather and climate on nature. This is a Citizen Science project from the Woodland Trust.
To see how this works see the BBC article here . Find out more about the Nature’s Calendar project here
Peat Free compost is here and ever improving – but it’s a challenge to get to grips with the changes in growing. To help, the RHS has started a ‘Peat Free’ advice service and it’s open to all, not just members. To ask your question, just send an email to Nikki Barker at peatfree@rhs.org.uk
It seems that we need to be more careful with watering – it’s not true that it doesn’t hold water well – but the top dries quickly and gives the impression of dryness. If we then water without checking further down, the waterlogged plant may die.
We all need to know more here. The RHS itself will be completely peat free by the end of this year.
Here’s more Peat Free advice for Gardeners – including helping out with your own compost….
Ecolocal run a wonderful range of courses on just the things horticultural that you might want to know or get better at. Based at ‘The Lodge’, a Victorian walled garden in Carshalton, their courses are led by their RHS accredited tutor and help raise funds for community gardening projects benefiting people with learning difficulties and mental health problems.
You may not be aware that they are also restoring the old walled garden, and have volunteering days where you could help. Find out more here

At our AGM in November, author Michael Gilson, spoke about the early days of the Dover House Estate, created on ‘Garden City’ principles as part of the house building initiative after the first world war. ‘Homes for Heroes’ were declared by prime minister Lloyd-George – which would include the right to green space to grow food. Each house would have it’s own green space and allotment plots would be part of the design.
Of course, many who rented the houses were not naturally green fingered, and had never owned a garden before, so Richard Sudell, a Quaker and political firebrand as well as a well known plantsman and garden writer took on the challenge of helping. He set up training allotments and gave lessons, forming the Roehampton Estate Garden Society. It seems that meetings of the committee took place in the basement at St. Margaret’s church, just below where we have our AGM. Roehampton became one of the leading garden estates in Britain as the country became the ‘nation of gardeners’./
Our centenary exhibition featured boards about this history – which are now in PDF form. We hope you will read and enjoy them.

In 1955 the two Roehampton horticultural societies merged together to become Roehampton Garden Society.

Agriculture and food growing is a huge growth area for robotics. With current difficulties in finding a skilled workforce to plant and pick, this may be the future.
M&S have just announced successful automated growing of parsnips – an industry first. The technology, includes two robots for bed forming, planting and weeding, two different types of drone to monitor and maintain crop health, and scientific testing on soil health and carbon impact. Green fertiliser, less diesel, less ploughing all combine to reduce the carbon emissions by an amazing 46 per cent. See more here
In another research project Cambridge university has trained a robot to pick iceberg lettuce – one of the most difficult crops to harvest! See more here
It’s still a challenge to train a robot to judge a ripe fruit or notice disease or damage as well as a human can, but the advances are fascinating. Take a look at the latest types of intelligent agricultural machinery.
13 types (!) of automated farm machinery working now
For anyone interested in a deep dive into how horticulture uses robots, this article from ‘Grower Experts’ explains how automation is used. Link here

There’s been a debate going on about growing garlic. Should you buy seed garlic – or can you use a supermarket bulb? Is it best to plant now (even September I have seen mentioned) or wait until early next year. How much water should you use – that balance between tiny bulbs and rotting stems.
Monty Don certainly caused controversy by planting a supermarket variety – some swear they grow well – but it will be next spring before the results of the Gardener’s World experiments are known. The latest information suggests that for good results you need garlic that grows in a cold climate – not that imported from sunnier climes. Also concerns have been raised about possible viruses on supermarket bulbs. Both of these concerns are valid.
The store has recommended varieties.
Here’s a great ‘No Dig’ video full of garlic information from Charles Dowding

One of the fascinations about our shows is seeing what other people grow. This year class C33 was for “a pot of one type of home-grown annual herb, growing” and had some interesting entries. Fresh herbs can be difficult to source – and some quite expensive for a small bag, so, if you like to cook, growing them yourself makes sense. If seeds are difficult to germinate, you can often buy a tiny plant in Springtime and grow it on to full size – as good as any houseplant! Take a look below for inspiration…
In spite of the weather and an early date this year there were lots of entries for the Autumn Show. Read the full report, with pictures and results, by our Show Chair Carol Martinez.

Tea and Cakes – Plant Stall
Our 100 plus visitors to our Nation Garden’s Scheme open day were delighted with their allotment walk, commented on the many beautiful things that there were to see – in particular two lovely clematis covered arches, and the tea space by the potting shed! Many of them stopped and asked questions on the plots – some shared this year’s gardening challenges.
Most enjoyed the magnificent array of cakes and tea, with outside service provided by our younger helpers – thanks to you all! Many bought plants from the plant stall.
The event was very well organised by the committee, and our sincere thanks to them and to the many who came to help and participated . A huge effort, but very much rewarded.
More than £1000 was raised for the NGS charities.
