I'll give you some insight into my routine, when a new shift starts I usually check to see if theres a chef, if not I usually go and interact with people but I grow 3 apple trees in case I need food or to make small parcels and give them too people, if there is a chef I plant all the possible plants I think they could want from apples to tomatoes and everything in between, I usually then go and finish my routine and find rp since theres no point in watching them grow, after a good 5-10 minutes I usually come back harvest all the plants and drop the off at kitchen, rinse and repeat since Botany is usually a lonely job and when another gardener is around they seem quite content on growing and experimenting on there own, so I usually come back every while to help out and deliver another load, but yeah it's true there is no point in sitting Botany all the time. If it's just me and another chef I usually give them the usual plants I think they would want/need and if they need more I let them use the department frequency and they always ask what they want there, I then go and grow it. That's all I can say really, that's what I do as my routine usually.
