Required Budget for Plants in New Garden

I didn't realise that soil goes down 2 - 6 Metres deep.

 

I dont see how anyone can really give you any idea, mostly because it depends on what plants, some plants spread more than others, also it depends also on planting density which is part of the same thing but how prepared are you to have some bare soil, maybe cover with bark while the plants fill out.
Probably garden designers come up with a figure, but most gardeners build a garden over a number of years with plants they personally like.

Otherwise you end up with something like council planting around a car park, putting it brutally.

 

Unfortunately like a number of people when gardening I often use depth or deep instead of width.
My soil is relatively shallow in places 6" to a foot in others a couple of foot.
When the fens were originally drained the peat went doen a couple of meters and more, but erosion, drying out and such like has significantly reduced that depth.
Alluvial plains and loess soils can be 2 to 6 m deep. Loess soils (which are wind blown or glacial deposits) can be 10 of meters deep, China's Yellow River region for example. These are also very prone to erosion, especially after deforestation.

 

I always thought soil went down until you hit bedrock. In some places that could be dozens of metres.

 

I agree with what everyone else has said lots of possibility's , I did some planting for a client not something I do to often I can't quite remember how big the area was probably is around 35 square metres I've probably spent about £1000 on it and that was me looking all over the place for good quality / cheap plants and added ones I've grown myself for free, I am working on putting more plants in as well.

I planted up my front garden last year its only small 13-14 square metres its probably cost me about £450 including bulbs . That includes couple of david austin roses - 3x lavender and few of shrubs - 10x grasses - 40x ish perennials and bulbs

I think you'll be looking at up to £800 for larger plants and around £500 for smaller possible cheaper if you have a good nursery / garden centre local.

If you have an idea of plants you want I can recommend a few online nurseries I like to use now and again .

 

Thank you all for the advice. I realise it's quite difficult to advise properly without more detailed information. I have a West facing garden so pretty much non-stop sun from Mid-morning to sunset in the summer. If anyone has any names of plants that I can add please let me know. Thanks again everyone

 

Many online websites will show what types of plants are best for full sun positions, like below.

Buy Shrubs for Full Sun - Jackson's Nurseries

I don't know these companies personally, but it will give you details, of the plants growth height and spread, plus they have images to go with the names.

To get ideas, I would type, garden border ideas in google and then click images, it will give you lots of different types of borders, hopefully you will then get some ideas of what you would like your borders to look like.

 

Not particularly. We spent a lot on 5 trees and bought about 2,500 bulbs. Large planters are expensive and as I said tools, chemicals and compost soon mount up.
