5 Things for Winter Sowing in Milk Jugs

Winter sowing is seed-starting for people without shelves and lights: jugs sown in January live outdoors until they sprout themselves in spring, pre-hardened and free. Five things run the whole factory.

Spring, self-starting
01

A safety cutter for jug surgery

Twenty jugs is forty cuts

WorkPro Retractable Cutter

The pick

WorkPro Retractable Cutter

$9.99 on Amazon

The winter-sowing production line starts with cutting milk jugs nearly in half - hinged at the handle - and a kitchen knife doing that through slick curved plastic is an urgent-care anecdote waiting. A retracting safety cutter makes the forty cuts of a January sowing session boring, which is the goal.

Cut three-quarters around; the attached handle-hinge IS the lid mechanism.

The seed-starting mix, again

Same soil rules, colder classroom

Back to the Roots Seed Mix

The pick

Back to the Roots Seed Mix

$8.80 on Amazon

The seed-starting kit's sterile mix does identical duty in jugs: clean, fluffy, damping-off-free. Four inches deep in each jug bottom - deeper than indoor cells, because these seedlings live in their jug into May and need root room for the long residency.

Wet it before sowing, drain before capping - soggy January soil is an ice cube.

All-weather tape

The hinge that survives February

All-Weather Duct Tape, 50 yd

The pick

All-Weather Duct Tape, 50 yd

$14.98 on Amazon

Each sown jug gets taped shut along its cut - and ordinary duct tape peels off frozen plastic by Groundhog Day, spilling the nursery. All-weather tape stays married to the jug through freeze, thaw and sleet until you cut the lids open on the first true warm week.

Cap OFF the jug spout always - that hole is the rain and vent system.

Oil paint pens

Sharpie ghosts by April, exactly on schedule

White Oil Paint Pens, 12

The pick

White Oil Paint Pens, 12

$13.99 on Amazon

The cruel winter-sowing joke is twelve identical jugs in April with sun-bleached Sharpie labels - a whole season's plan reduced to 'probably tomatoes?' Oil paint pen on the jug side (and on a tag inside, for belt-and-suspenders) survives the full outdoor residency legible.

Label the JUG SIDE, not the cap - caps are off, remember, and they wander.

05

Wooden labels for inside

The inside witness

Bamboo Plant Labels, 90-Pack

The pick

Bamboo Plant Labels, 90-Pack

$12.99 on Amazon

Every jug gets a second label INSIDE - a pencil-written wooden tag that backs up the painted outside, because one of the two always fails and it is never both. At transplant time the tag moves to the garden row with its seedlings, keeping the name attached to the plant all season.

Pencil on wood outlasts every marker - the graphite rule, one more time.
