A liquid feed can reach plants faster than solid compost, useful in a growing season this short, but at altitude the same freeze-thaw pattern that governs the heap itself governs brewing, storage and timing here too.
Brewing Compost Tea Without Losing It to Frost
The basic method is simple: steep finished compost in water, ideally aerated or stirred periodically, for a day or two, then dilute before applying. The genuine climate-specific caution is that a liquid left outside overnight at altitude can freeze, so brewing and storage need to happen somewhere protected, a shed, a sheltered lean-to, or indoors, rather than left in an exposed bucket through the cold hours. Apply during the mildest part of the day rather than leaving a finished batch sitting exposed waiting to be used.
Urine, the Simplest Always-Available Feed
Diluted 1:10 with water, urine is the simplest liquid feed available, and genuinely valuable here since it doesn't depend on the short growing season or on plant growth to produce, unlike a compost tea that needs finished compost on hand first.
Manure Tea, Stretching Limited Fertility Further
Livestock manure from Chapter 6 can be steeped and diluted the same way as finished compost, giving a water-efficient way to spread limited fertility across a small growing area rather than committing all of it to one part of the ground as solid compost.
Timing: the Mild Middle of the Day
Apply any liquid feed during the mildest, most reliably above-freezing hours of the day, typically around midday given the daily temperature pattern covered in Chapter 11. Avoid early morning, when the ground may still be frozen, and avoid evening, when temperatures are already dropping back toward the next freeze.
Frequently Asked Questions
Can I just leave compost tea brewing outside overnight?
No, a liquid left outside overnight at altitude can freeze, so brewing and storage need to happen somewhere protected. Bring the container indoors or into a sheltered structure rather than leaving it exposed through the cold hours.
What's the simplest liquid feed for this climate?
Urine diluted 1:10 with water. It's genuinely valuable here because it doesn't depend on the short growing season or on plant growth to produce, unlike a compost tea that needs finished compost to steep in the first place.
When's the best time of day to apply a liquid feed here?
The mildest, most reliably above-freezing hours of the day, typically around midday given the daily freeze-thaw pattern. Avoid early morning, when the ground may still be frozen, and evening, when temperatures are dropping again toward the next freeze.
