FYI: Soil Mixes for Class Use

A delivery of  three cubic yards of compost at The Learning Garden is cause for celebration because we use it in all our garden beds as well as in our general use potting mix.  It must be screened by a fairly fine screen for the regular potting mix; an even finer screen is essential if one wishes to use compost for sowing seeds.

Basic Mix with Compost

2 parts Sifted Compost
2-4 parts Sphagnum Peat Moss
2 parts Perlite
3 parts sand
(Note: compost provides some basic nutrients for plants and should enable a few weeks growth without additional fertizlation.)

Cutting Potting Mix 1:1

1 part peat
1 part sharp sand

Seed Starting Mix 1:1

4 parts peat
4 parts vermiculite
