Shaun Schroeder, 61, spends up to three hours each evening tending his 200 hanging baskets.
And he appears to have surpassed himself this year after a teenager asked to have her pre-prom photos in his garden.
The grandad-of-two got into gardening during lockdown and found himself hooked.
He now re-designs his garden each year, with a totally different look every time.
Shaun, a demolition supervisor, said: "Everything dies in winter then I have a blank canvass.
"it's totally different this year, all different plants and they are all arranged differently."
Shaun plants everything in one manic week in May so everything blooms at the same time around late July.
He spends all summer maintaining the garden, removing every slug and snail by HAND to ensure they don't ruin his handywork.
Shaun budgets around £1,500 per year for the garden - including all plants, compost, fertiliser, pots and tools.
Shaun, based in Whitchurch, Bristol, said: "The garden is in full bloom at the minute - this year the 200 hanging baskets are looking tip-top!
"The older I get, the harder work it is to keep on top of everything, but it's such a lovely job."
And he was paid the ultimate compliment this year - when one of his mate's nieces asked if she could have her pre-prom photos taken in his garden.
Shaun said: "I was surprised - but I guess I must be doing something right!"
Shaun says the garden helps him destress after a long day of work.
"It's relaxing to get out in the garden - even if just to look at it.
"But it's not just for me, I do it so everyone else can enjoy it too."
Gardening became his passion during lockdown when people walking by would tell him that it "brightened up the doom and gloom during lockdown."
He even had people post letters through his letterbox praising his multi-coloured garden - and locals taking detours on their daily walks just to pass by for a peek.
Shaun books a week off work to have a solid week of planting ready for the summer bloom.
This year he planted more than ever including 1,000 petunias, begonias, fuchsias, calibrachoas, impatiens, geraniums, lobelias, and verbena.
This includes precisely 200 stunning hanging baskets spilling over with the brightly coloured flowers which make his garden a local tourist attraction.
Shaun, who lives with wife Jan Schroeder, 60, said: "I'm lucky I have an understanding wife who lets me spend all weekend in the garden!"
Speaking of his nightly slug patrol, he said: "That's my 10pm ritual - to go and pick them all off and relocate them. I get more than 100 off every night!
"They'll slaughter your plants if you let them and the pellets don't work these days."
He said with costs rising, plants have become more expensive, but he's tackled that by doing more cuttings - so propagates plants rather than buying them all new.
This way, a plant costing £3 can generate ten cuttings - meaning each plant only costs 30p.
Around 500 of the 2,000 plants in his garden this year were taken from last year's cuttings.
Several years on from lockdown, Shaun's main motivator remains to give others a lovely display to look at.
He said: "A lot of the residents around Whitchurch take detours to go past my garden.
"They love to come up and have a look at it and I'm always willing to show them around too if they want.
"Some walk by in the evenings and tell me it looks fabulous and people are always knocking on the door.
"I run a gardening Facebook group, but I've never tried to profit from anything - I just do my gardening so everyone else can enjoy it."
