Hello Fanny.
I pay my "girl" £17 ph but today she told me it will go up yo £19ph. She comes for 3 hours each week all year round.
She has a horticultural qualification and brings her own tools.
She mows in Summer, makes and uses compost, prunes, mulches, plants out shrubs and trees and does any jobs needing doing.
For the last 3 years she's been cultivating a meadow on part of the lawn, sowing yellow rattle to reduce the grass etc.
I do some gardening (I look after the greenhouse and veg) but it's huge and overwhelming.
She has 30 clients but I don't know how many hours she does for each of them.
When my friends ask her if she will work for them she says she's fully booked.
My neighbour, a home for the elderly disabled uses a contractor who keeps lawns and shrubs tidy.
