Below is a list of common spring tasks we carry out in our West Coast gardens.

1.  Aeration: this extracts core plugs from our lawns to allow water and oxygen into the root zone. If you don't do anything to your lawn all year, then at least aerate it in spring. Fall aeration is also common. Leave the plugs on the lawn to disintegrate. I don't like to rake them out.
2.  Planting: spring is a great time to put new trees and shrubs in the ground before it gets too hot. Trees need time to establish so water them properly. 
3.  Power raking: when your lawn is in a bad shape with lots of thatch build-up, you can rip it up with a power rake. Choose whatever setting you want from severe to a gentle tickle but don't forget about clean-ups. The power rake makes a lot of mess; you will generate lots of green waste. Top-dress with good lawn mix soil and over-seed.
4.  Lime: this is applied before aeration with the idea of lowering the high pH levels in our acidic West Coast soils. But, don't expect miracles because drastically changing soil pH levels is hard to pull off.
5.  Fertilizer and moss control: you can apply them separately or in one bag but the moss killer has iron in it so it will stain if it gets into contact with water. It looks awful on the bottom of your swimming pool so blow the area as soon as you apply the product. 
6.  Deep edging: touch up your deep edges around tree wells and planted beds for definition.
7.  Hydroseeding: a quick spray which includes seed, fertilizer, wood fibres and glue.
