ABC of amaryllis, bonsai & cyclamen

I've been guesting on Ken Crowther's gardening programme on BBC Essex again, sorting out the county's problems.
It's odd how questions go around in packs/trends and this time everyone was fretting about their Christmas purchases or Christmas presents.
How to look after amaryllis (don't just chuck them away after flowering but keep them growing), bonsais (by the dozen) dropping leaves - mainly due to overwatering - and cyclamen not flowering - or flowering very well if the callers were showing off. One caller had flowers on 30cm long stems - a tree cyclamen.
One caller wanted my thoughts on composts and fertilisers for his crops on the allotment - not an easy answer to give in two minutes - especially as he had spoken to other people, read several books and they all contradicted each other/gave different advice and his head was in a spin. My 'Hodge's guide to soil & plant feeding in two minutes' seemed to sort things out for him. One of the things he'd read was that he needed to apply ammonium nitrate now, followed by sulphate of potash in February, followed by ... I just told him to chuck a couple of ounces of Growmore around. As you'll see I like to make things simple.
Sadly, we then had follow-up calls asking why I hadn't featured feeds for this situation or that plant or the other condition. My suggestion of a two-hour programme dedicated to compost, manure and fertiliser didn't go down too well with the powers that be at Essex - surprisingly. Some people say I speak a load of old compost all the time anyway.
Another caller then wanted 'Hodge's two-minute guide to potting composts', which opened a whole new can of worms - almost literally!

Tomorrow I'm off to BBC Radio Cambridgeshire to do their gardening slot at noon with the lovely Philippa Pearson. More muck & magic?
