First step is know your audience or in other words who is it for? As BBC3 has been a "youth oriented" channel and is about to move to online only that would imply a different approach is needed than that used for the more mainstream audience for such shows on main channels.
Everybody has to start somewhere so there may be some mileage in a "Delia - How to Boil an Egg" approach. Simple things like how to choose and use the right tool for the job can make a real difference to getting people hooked on gardening. None of us is born knowing how to do this. Start with the basics like spade and fork - there is a wide choice available but if you don't know how to use them correctly it is easy to pick the wrong tool and make life much harder for yourself and probably give up. That can easily be a running segment in any series as there is a vast array of hardware out there. Maybe try a Mythbusters approach on things like bulb planters (mostly useless).
Perhaps the target audience is the post BBC3 audience - those mythical first time buyers with a small blank patch behind the house. That has been tackled many times before, most recently by Chris Beardshaw in the Beechgrove series.
While that was good I did wonder about the costs involved which are likely to be a major factor for people starting out. For example a lovely stone retaining wall might be the most effective solution to a sloping back garden but £k's for landscape engineering is not something first time buyers have lying around. A favourite topic round here is pallet engineering for garden use - cheap solutions in the Geoff Hamilton style.
