‘’Absolutely brilliant – a superb seminar and a real eye-opener. We usually do everything ourselves at Wanstead Bowls Club in Essex, so it was really important for us to learn more about the science behind it all. Lots of useful information to take away. There are a lot of clubs out there that need this kind of help, and it can be hard work getting them to wake up to the importance of greenkeeping. I’d be more than happy to host one of these seminars at our club.”

The whole day was really helpful from the initial lectures on lawn management to the practical session on Lawnmower maintenance (a revelation!) To the practical demonstrations of the various machines and the final lecture.

“The main theme for me was ‘out with the old and in with the new.’ We’ll definitely be putting into practice what we’ve learned going forward. Stuart and Jason have been excellent – knowledgeable, witty and funny with it. They really know their turf and put it across in a way that makes it easy to understand and enjoyable to learn.”

A fantastic day for networking with other like-minded people who face the same challenges we do. The seminar was packed with practical advice and insights and it’s great to share experiences and solutions with others in the same boat. I’d highly recommend it to anyone involved in greenkeeping – it’s not just about learning, it’s about connecting and taking away ideas you can actually use. We can’t wait for next year.

A very informative day – I’ve never been to anything like it before. I started out helping on the green with almost no knowledge about how it worked, but the seminar was incredibly clear and easy to follow. I’ve come away with a solid plan to help improve our green and keep it in top condition going forward. A great experience for anyone looking to learn practical, hands-on greenkeeping skills.

I have found it extremely reassuring that everyone is in the same boat. We all have the same struggles no matter where we work or what our job title is. Today has been brilliant and offered so many  solutions.

“The seminar was engaging and got everyone involved. As a crown green club, our challenge isn’t keeping a flat surface but managing the dips and swerves that make the game interesting. I took away practical advice I can use, like the importance of regular spiking to get air, water and fertiliser into the soil. It may look messy at first, but it benefits the green long term. We’ve attended seminars before, but this one stood out for its useful ideas and focus on small, consistent improvements that make a real difference. It’s well worth attending for anyone looking to improve their greenkeeping.”

The day was full of really useful information throughout. I came to learn more about machinery and the proper way to use it, but I also picked up a lot about topdressing – I realised I’d been doing it wrong and now understand the better practices to follow with the machinery. A very worthwhile seminar.”

Hanbury & Draycott
‘’I’ve been on one of these seminars before, which was good, but this one has really taken things to another level. I’ve learned so much about the importance of aeration and how it’s all about prevention rather than cure going forward. The message of ‘little and often is the key’ really stood out to me. Sessions like this are invaluable for helping clubs like ours to understand what’s needed to keep our greens healthy and playable.”

''Today I was lucky to be invited to the SISIS/Dennis seminar which was held at Wantage bowls club.This was great as we were able to see different types of machines working on a real green- its not the same as watching a video. We were able to ask questions about all aspects of the use of them.The other great part about these seminars is you can also get to talk to other greenkeepers and share things with each other. I would highly recommend going to one if you get the chance as I know their will something you will learn and you can then go back to your club with the knowledge of the next machine to purchase'' Robert Black (Ramsbury and Aldbourne BC)
