Timing
- Early Autumn & early Spring
- Ground preparation sould be done 1 month before sowing
- Most work must be done in dry conditions
Soil
- At least 15cm inches of top soil is needed
- Too little tipsoil leads to stress in drought
- Grass prefer a light, Well drainied soil
- Clay soil which is heavy & damp = moss + slow Spring growth
- Sandy soil which is light & dry = clover
Step 1: Preparation
- Weed kill the existing vegetation prior to ground preparation
- Two applications of a non-selective, contact weed killer may be required to kill off all perennial weeds
- Before sowing the seed it is important to prepare the soil
- Dig the soil to a depth of 15cm
- Remove larger stones as you dig and turn the soil
- Roughly level your soil with a rake and allow to settle for a week if possible
- Rake to the sides to remove new weeds and smaller stones to create a fine seed bed
- Firm the soil by treading the site evenly or using a light weight roller
- Then rake the soil again
Step 2: Sowing the Seeds
- Choice of seed?
- Grade 3 is a good choice for lawns with heavy traffic
- Grade 1 would be for infrequently trafficed manicured lawns
- Sow April to Mid October on a calm & dry day
- Sowing rate of 35g (a good hand full) per m2
- Too little seed means your lawn will be slower to establish or may have weeds
- Too much seed leaves your lawn prone to disease
- Scatter seed evenly - first moving left to right and then up and down
- You could also use a broadcast spreader to do this job
- Lightly work the soil with rake from left to right and back & forth to bury seeds to roughly 0.5cm depth
- It is recommended that you water in your seeds if possible
Step 3: Caring for New Lawn
- The grass should appear after 7-21 days
- Once it appears make sure to keep the lawn watered using a fine water setting
- Do not cut the lawn until it reaches a height of 8cm (3")
- Gradually reduce blade's height until it is reduced to 2.5cm (1")
