A word of warning,
purchase perlite, vermiculite and rockwool as only horticultural
quality. Don't be tempted to obtain it from a builders merchant
selling it for insulation, it is impregnated with insecticide and
fungicide and not suitable for the growing of plants.
Don't add anything else
whatsoever to the aggregate.
Consider the savings in
manual labour by using this aggregate along with the superb air-pots.
No more lifting heavy
pots with heavy composts. Transporting and carrying loams, grits,
composts, peat and whatever else is used. Also consider the tasks
involved mixing and turning.
The aggregate can be
reused after use ,but not on chrysanths. Use it for tomatoes, etc
outside beds for drainage and to help texture. Makes a wonderful top
dressing for high quality lawns.
Just one rule to learn
- KEEP IT SIMPLE!
