A soil that is not compacted, is friable (crumbly) and is the main reason for productive Everlasting growth and establishment.
Friable soils have better aeration, allowing the roots to freely explore to access nutrients and moisture.
If your Everlastings are short and stunted, soil compaction may be an issue. To ameliorate this problem, you may like to;
– till the soil with a shovel or rotary hoe
– apply gypsum
– add organic matter or mulch such as pea hay
– reduce traffic over the garden
– grow a deep rooted plant for a year, or over the summer break
Soil compaction generally applies more to clay-based soils, thus the reason everlastings are suited more to sandy/loamy soils.
If the only option you have for growing Everlastings is clay, try the amelioration methods above!
