Please click on the following links for more information.



Please let us know if we can be of any more help.

( clive, 27/07/2017 ) Q:

How do you do the practicles? I did RHS L2, is this a similar level, thanks.

( 31/07/2017 ) A:

Hello Clive,

Thank you for getting in touch.

Most of the practical aspects of the course involves further research, rather than actual hands-on work. The parts where you will need to show some hands-on.can be done from home.

If you have completed RHS level 2, you may like to consider moving on to RHS Level 3, which builds on what you learn in Level 2. We have two courses that are level 4, which students also use to study for RHS level 3. Here are the links:



Horticulture I is Level 4.

We hope that this answers your question and please come back if you need anymore information.

( Zoe Geal, 06/05/2014 ) Q: Hi there, I am interested in booking this course and wanted to double check what qualifications I would receive upon completion of the course. The information says 'certificate' and I wondered if you could provide more detail. Kind regards, Zoe
( 07/05/2014 ) A: Hello Zoe, Once you complete Horticulture I, ADL will issue you a certificate. You can read more about what you will receive once you complete your course here: http://adlonlinecourses.com/blog/whats-in-it-for-me

student comment:

"Hi there
I would like to submit my Horticulture I BHT101 assignment 10 on Landscaping for marking please to my tutor, Sue Stephenson.

This assignment has been a really interesting one for me and has taken me much longer than normal, but, I've enjoyed working on it as I've never 'attemtpted' to put together a garden design before - very thought provoking. Thing is, it's like a painting isn't it, how do you know when it is finished!"  Tracey  R, Horticulture I BHT101, UK
