Possibly non allergic rhinitis. But I'm no doctor! I get the same symptoms. The cough could be post nasal drip. Try Beconase. I use it for allergic rhinitis (as opposed to non allergic)
Yes could be. Some time ago, in a galaxy far far away, when you could get an appointment to meet a Doctor face to face, the post nasal drip thing was highlighted and a steroid spray prescribed, which helped. But like many people, I don't like long term medicine use, especially of steroids. I am thinking though that that is probably the problem and the triggers are all around: dust, air pollution and these various things in the garden.
I find there are plants like herb robert that set me off - itching throat and coughing. Also when our trees or ivy are pollarded there is a foul amount of dust and horridness that comes off them. Maybe trying using a mask for a week of gardening and see if it helps. As a test.
I started commuting to work by bike, after 18 months I developed a cough shortly after finishing my half hour ride to work. Doctor thought asthma and gave me a puffer of salbutamol. It worked well which means the cough was asthma.
Basically a mix of exertion and allergic reaction to something combined to give me that cough. However I have no idea what is triggering the allergies. At home we suspect it's ivy or mould spores of some kind in the damp air.
One thing we spotted once. Driving back home from two weeks away we spotted that allergies were not noticeable until we pulled off the motorway a mile from home. The small town I live in and I'm allergic to it.
It could be asthma from exercise or from something in your garden..
Like @SydRoy said, I'd consider some sort of allergic rhinitis. Getting that bunged up feeling in the morning would suggest breathing in dust during the night (I'm sure we all do that to some extent) or sleeping with the mouth open perhaps. Hard to say if there is a garden connection though.... I have similar symptoms but don't take anything for it apart from having a supply of mints to hand for dry throat, wearing a mask all day at work doesn't help.
