For those of you interested in cultivating the grasses or finding wild populations this week is pivotal for sequencing a fall harvest schedule.
I see heavy clouds in the sky today and have been transplanting what little of my Phalaris farm that is left. When transplanting and dividing rhizomes I have been clipping them down near their base so as to ensure vigorous new growth. Also, I have clipped my homegrown P. Arundinacea 'Yugo Red', Aquatica, and non-cultivar Arundinacea down so the remaining stands are ranging from a few inches to a foot tall.
For transplanted plugs:
Since you hopefully have already clipped the excess grass down near the base, you have already taken care of one of three cuttings you'll be making.
When the rain nourishes new spikes of Phalaris to rebirth, allow initial growth to reach a foot or so. If rain is minimal, water your plants incrementally once or twice a week. You should be allowing a few dry-spells here and there to stress the plant, therefore stimulating accumulation of secondary metabolites. You will notice the plant's foliage and stalks reddening or turning purplish and overstressed leaves turning straw/strawberry hay colored. Meanwhile, you should be applying a nitrogen fertilizer such as Ammonium Sulfate or dilute Urea in weekly intervals(or when you water the plants). This should take around 3 weeks. So it will be early September when you are ready to make your second clipping though this amount may be stored in a freezer or discarded and reapplied to the stand as self-mulching. Near the end of September is when your final clipping will occur(This is the harvest of the Second New Growth)
Untapped plants:
Coming back from summer dormancy, your grass may range from completely dried out, yellowish green, silvery blue, or green and hints of strawberry hay colored foliage.
When you sense the first rain after a long period of heat and dryness, clip the plant down to where 1/3 of the plant remains. You should be watering the crop at the same time. Allow this first regrowth to reach a foot or two in the three weeks after. Rain and cooling environmental factors should return this growth rate to normal. (Worm tea helps). In the meantime, you should be applying a nitrogen fertilizer such as Ammonium Sulfate or dilute Urea at weekly intervals(or whenever you water your plants). When this new growth is ready, simply cut it back to where you originally made the first cutting. Freeze or discard this amount. Allow the grass to regenerate for another three weeks, repeating your fertilizing regime. This will be your final harvest for the season, then constituents will decline rapidly in concentration. (Third regrowth will do though you'll notice diminishing concentrations).
Notes:
If plants experienced full Sun during the summer, you may move the plants to the shade to begin managing production of the medicine. This will ensure steadier increases in what you want, though growth will be much slower. Adjust to allow 4-5 weeks in between harvests. This will make it later in the season so I would recommend beginning now and not procrastinating with the path of the grass.
Now is optimal time for germinating seedlings for a late October harvest...
This is all I have to say for now, updates may be added.
Open to suggestions or others' experiences; post 'em here.
