On regular occasions New Builds and Builders tend to leave alot of building rubble and crud in the grounds surrounding the newly built house.So the 1st thing to do is check the actual quality of the ground and soil below your feet.Dig down a good 12-15 inches to see what is really under your feet.No point in planting lots of lovely trees,shrubs and plants if you have only have 1 inch of topsoil on the surface but 11 inches of builders rubble and crud below.
Also if a builder mixes up all the subsoil with the topsoil he originally dug out and throws it back in,then all he has done is ruin the ground and new plants and shrubs will not take in subsoil.
Soil quality and soil structure is vital to how successfull a new garden establishes and grows.You need a good 8-10 inches of propper topsoil to create and plant new gardens.You also need to take into account if you need any manure and grit added in,depending on ground conditions and plant types you are planting.
If you take the time to plan out a garden space and plant ground cover plants and shrubs,then theres no need for Mypex,as Mypex can actually be bad and surpress plant growth and plant spread.Mypex will also prevent the spread of tuborus plants,flowers and bulbs and rhizome type plants and flowers.
Fill the space with suitable trees,shrubs and ground cover plants and you wont have any problems with weeds.Take into acount whether the area is shaded or in sunlight and also how dry or wet the soil structure is in the area.Also whether the area faces North,South,East or West with regards to weather patterns and prevailing winds.
Plan and plant the area accordingly with regards to the seasons and you will be rewarded with a fantastic garden of colour and beauty all year round.
Thats what we did with our new build.
