vom Wirken und Schaffen Dieter Meiers profitieren

I agree with Ramey's suggestion. As it stands, the first sentence doesn't make sense until you've read the second.
I do suggest you have it edited by a native speaker. It sounds like your translation will be quite prominent, and perhaps read by a lot of people.

The awkwardness comes from the text's chronology. If you have the freedom to do so, switch the sentences sequence:

1973 gründete er die D. Meier AG in Wien, heute eine der größten Hersteller von Kräutertees und Fruchtinfusionen auf dem österreichischen Markt.
Auch heute noch können Sie ***vom Wirken und Schaffen Dieter Meiers profitieren***.

In 1973, Dieter Meier founded his D.Meier AG in Vienna which has grown to be one of the largest producers of herb teas and fruit infusions in Austria.
You, too, can enjoy the benefits of Dieter Meier's lifelong/life's work.

Even today, still today, to this very day, forever and ever, amen...are not really necessary when speaking in the present tense - it's a given.

Sein Wirken und Schaffen, von dem wir heute noch profitieren, ist der Tee, den wir noch heute kaufen und genießen können? Oder der von ihm angelegte Garten, den wir noch heute genießen können?

We are translating copy for a singular plaque at his earlier place of work, where he laid the foundation and engineered/created stuff for his subsequent herbal tea and fruit infusion empire :‑).

So this is some kind of memorial plaque to his life's works at a certain exhibit? Or is it at his own garden/business? The question is, is Dieter Meier one of many commemorated gardeners at something like a permanent garden exhibit, or is it a singular plaque at his earlier place of work?

Dieter Meier is dead. The various garden styles are linked to a specific topic in each case (sometimes this would be the life and work of a special person who previously owned and maintained the garden) and are not being compared. The individual garden copy will be put onto informative steles that apparently (or so it seems as per the German published reference PDF) welcome the visitor to the place and introduce them to it.

16:13 Jul 18, 2019 

What kind of text is this? A book? Are the varying garten styles being compared? Rated? Is Dieter Meier dead? Has he (or his people) published a book?

15:57 Jul 18, 2019 

OK.

15:54 Jul 18, 2019 

Not "we". It says "you", which is slightly unusual because German often avoids this word in such contexts. But this is marketing, and you have to appeal directly to the reader.

"Even today, we stand to gain from Dieter Meier's influential contributions."
