I'm a plant serial killer.
I over water them due to love and they drown. I don't understand how to control direct sunlight. Maybe they don't like my house and off themselves.
My mother on the other hand, gifted. She designer the whole thing, loved doing it, it's freaking gorgeous. All the right flowers and plants in the right place so they grow, herb and vegetable garden, water fountains, fairy lights, tree, places to sit, kids stuff, it's gorgeous.
I was allowed to assist in planting, I had one I was in charge of, under supervision. It was like being six again:)
I just have instructions, what to water, when and how (yes there is a how).
If you have neighbours with gorgeous gardens, tell them you love what they've done and it's beautiful, you're new with a garden and not sure what you're doing, can they give you some advice?
If they are retired and in good health, they'll probably love to get involved. My mother happily puts flowers and plants in her elderly neighbours gardens, they said the flowers were brightening their day, she was thrilled to share as gardeners do really love it! I see the appeal, something I never thought I'd say. Hopefully I'll take it up when I can be trusted:)
Or yes, get a gardener, tell them what you'd like, low maintenance as you are new, have them get you set up, tell you how to take care of things!
Voila, gorgeous garden!
