Choose your first pot.

Spinach

A cool spring or fall spell

Pot
12 × 12 × 12 in.
Start with
8 seeds → 4 plants
Light
Use a sunny spot; give afternoon shade when days warm up.
Shopping & care for spinach

Planting notes

One square planter with drainage holes. The shopping calculation uses inside dimensions.

Two seeds per spot, in a 2 × 2 grid, 6 inches apart.

Sow two seeds at each of four positions; thin to four plants. Keep the seed surface moist.

What to buy

Buy 1 × 1 cu ft bag.

Mix: Miracle-Gro Organic Potting Mix (US) — bag details

Shopping allowance: Budget up to 26 L (0.92 cu ft).

How this amount was estimated

Worked example: a straight-sided planter with INSIDE dimensions of 12 × 12 × 12 inches, filled to 1 inch below the rim. A tapered pot or nursery starts use less fresh mix. If your planter is deeper, check its capacity before buying.

How to measure the mix for your pot — shared instructions

Starter nutrients — shared instructions

Water & later feeding

Water: Check each morning. Water as the mix starts drying; wait if damp. Wet the root zone and let excess drain.

Later feed: Miracle-Gro Water Soluble All Purpose Plant Food (US 24-8-16)

1½ tablespoons in 1½ US gallons of water

How to apply a diluted batch — shared instructions

When: Every 14 days during active growth.

Start / pause: Skip extra feed at planting. Follow your potting-mix bag’s starter-feeding directions before adding this routine; “up to 2 months” is not a fixed waiting period. Feed only while actively growing. A short crop may finish without extra feed.

Mix: Miracle-Gro Organic Potting Mix (US) — bag details

Shopping & care for blueberry

Planting notes

Choose Peach Sorbet (ZF06-043), sold as a compact, self-fruitful blueberry.

Choose Peach Sorbet (ZF06-043). Check the mix pH and plan winter protection for the pot.

What to buy

Buy 1 × 1.5 cu ft bag.

E.B. Stone Organics Azalea, Camellia & Acid Mix · 1.5 cu ft bag · about 42.5 L

Shopping allowance: Budget about 36 L (1.28 cu ft); the root ball and taper reduce fresh mix needed.

How this amount was estimated

Worked example: a cylindrical pot measuring 16 inches INSIDE across and 12 inches deep, filled to 1 inch below the rim. This is a shopping allowance, not a claim that every 16-inch pot has the same capacity. Do not force the entire bag into the pot.

Measuring the pot: Before planting, measure loose mix into the empty pot with a marked 1 US gallon container, up to the intended fill line. Record the volume, then remove enough mix to fit the nursery root ball. A nursery pot marked “#3” or “trade gallon” is not a measured US gallon. Leave space for watering; keep spare mix for later. For a later soil-based fertilizer dose, use the total filled growing-medium volume, including the retained nursery root-ball medium. New mix added and bags bought are not that total.

Starter nutrients: This mix contains nutrient ingredients. Skip added fertilizer at planting. Ask the nursery how long its existing feed lasts before starting the later spring feeding plan; the soil maker gives no fixed feed duration. Target pH 4.5–5.5 for the plant; the bag does not guarantee that number, so have the medium checked.

Water & later feeding

Water: Check daily in warm weather. Water as the surface begins drying, before the root ball dries through; wet the mix slowly and drain.

Later feed: Down To Earth Acid Mix (US 4-3-6)

1 tablespoon per actual US gallon of growing mix (5 tablespoons for 5 gallons of mix)

What this amount covers: Dry granules per total actual US gallon of growing medium, including retained nursery root-ball mix; not per gallon of water, fresh mix added, or bags bought. Measure the filled root-zone volume before planting.

When: Early spring and once more in late spring, at least one month apart.

Start / pause: No added feed at planting. Begin only once established and the nursery or fresh-mix feeding program has ended; ask the nursery if unknown. Skip summer and fall; if planted after spring, wait until next spring.

Spread away from the stem, work in very shallowly without damaging roots, then water. This fertilizer is not a substitute for checking soil acidity.
