Grow a Garden 2 Crates: What It Means & How

“Grow a garden 2 crates� is not a standard gardening instruction—it’s a phrase that appears in a few different contexts, most commonly as a shorthand for growing vegetables in two shipping crates or milk crates, or as a mistranslation of a game quest. If you’re here because you want to know how to grow a garden in two crates, the answer is: yes, you can grow a surprising amount of food in two 18-gallon (68-liter) plastic crates, especially if you choose compact crops and use a good soil mix. This article explains what the phrase likely means, how to set up a two-crate garden, what to plant, and common pitfalls.

Formula

For a standard 18-gallon crate (about 24 × 16 × 12 inches), the usable soil surface area is roughly 2.7 square feet (0.25 m²) and the soil volume is about 2.5 cubic feet (70 liters) per crate. The calculator above uses these approximations:

• Total soil surface = number of crates × 3.5 sq ft (this assumes a slightly larger crate, 24 × 21 inches).
• Total soil volume = number of crates × 2.5 cu ft (the actual volume of an 18-gallon crate is 2.4 cu ft, but you won’t fill it to the brim).

The variables are: c = number of crates, t = total growing days (used only for planning, not in the formula).

Worked Example

Using the defaults (2 crates, 60 days):

1. Soil surface: 2 × 3.5 = 7.0 sq ft
2. Soil volume: 2 × 2.5 = 5.0 cu ft

So with two crates you have about 7 square feet of planting space and need about 5 cubic feet of potting mix (roughly 37 gallons, or 140 liters). That’s enough to grow, for example, 6 lettuce plants, 4 bush beans, or 2 tomato plants (with support).

What “Grow a Garden 2 Crates� Usually Means

The phrase isn’t a common idiom. Searching online, you’ll find it most often in two contexts:

• Gardening in shipping crates or milk crates – a form of container gardening, popular for small patios, balconies, or urban yards. Two crates give you a manageable mini-garden.
• Video game quests – some games (like farming simulators) have tasks like “grow a gardenâ€� and “collect 2 cratesâ€� that may be mistranslated or combined. If that’s your case, check the game’s quest log for the exact objective.

This article focuses on the real-world gardening interpretation.

How to Set Up a Two-Crate Garden

Follow these steps to turn two crates into a productive garden:

1. Choose the right crates – Use food-grade plastic crates (milk crates) or wooden shipping crates. Avoid crates that held chemicals. Drill 4–6 drainage holes in the bottom if they don’t have them.
2. Add a liner – Line the inside with landscape fabric or a burlap sack to keep soil from spilling out while still allowing drainage.
3. Fill with potting mix – Use a high-quality potting mix (not garden soil, which compacts in containers). For two crates, you’ll need about 5 cubic feet (140 liters).
4. Place in full sun – Most vegetables need at least 6 hours of direct sunlight. If you only have partial sun, choose leafy greens.
5. Plant appropriate crops – See the list below.
6. Water regularly – Containers dry out faster than ground soil. Check daily; water when the top inch of soil feels dry.

What to Plant in Two Crates

With limited space, choose compact, high-yield crops. Here’s a practical guide:

• Leafy greens (lettuce, spinach, arugula) – grow quickly, can be harvested as baby leaves, and don’t need much depth.
• Bush beans – compact, productive, and can be planted in succession.
• Radishes – mature in 3–4 weeks, perfect for small spaces.
• Herbs (basil, parsley, cilantro) – grow well in crates and are useful in the kitchen.
• One or two tomato plants – need a larger pot (at least 5 gallons each), so a single crate can hold one tomato if you use a cage.
• Peppers – one plant per crate works well.

A typical plan: one crate for leafy greens (about 6–8 plants), the other for two bush bean plants or one pepper plant. That gives you a continuous harvest for a few months.

Common Problems and How to Avoid Them

Container gardening has its own challenges:

• Overwatering – Drainage holes are essential. If the soil stays soggy, roots rot. Use a well-draining mix and don’t let the crates sit in standing water.
• Underwatering – In summer, containers may need water daily. Add a layer of mulch on top to retain moisture.
• Nutrient deficiency – Potting mix has limited nutrients. Fertilize every 2–3 weeks with a balanced liquid fertilizer (e.g., 10-10-10) at half strength.
• Root bound – If plants outgrow the crate, you’ll see stunted growth. Choose appropriately sized plants or move to larger containers.
• Pests – Aphids and spider mites can attack. Check leaves regularly and rinse with water or use insecticidal soap.

Costs and Alternatives

The cost of a two-crate garden varies, but here’s a rough estimate (not including plants):

• Two plastic crates: $10–$30 (or free if you find them used)
• 5 cubic feet of potting mix: $15–$25
• Seeds or seedlings: $5–$15
• Fertilizer: $5–$10

Alternatives to crates include:

• Grow bags – fabric pots that are cheap and breathable.
• Five-gallon buckets – easy to find, but need drainage holes.
• Raised beds – larger upfront cost but more space.
• Window boxes – good for herbs and small greens.

If you’re on a budget, start with two crates—it’s a low-cost way to test container gardening before investing in a bigger setup.

Safety and Food Safety

When growing food in crates, ensure the crates are safe for food contact:

• Use food-grade plastic (look for recycling code #2 HDPE or #5 PP).
• Avoid crates that previously held chemicals, oil, or other non-food items.
• Wash the crates with soap and water before use.
• If using wooden crates, make sure they’re untreated (no preservatives like creosote).

Also, always wash your produce before eating, and use clean potting mix (not soil from your yard, which may contain pathogens).

Frequently Asked Questions

Can I grow vegetables in a milk crate?

Yes, milk crates are a popular choice for container gardening. They’re sturdy, have built-in ventilation, and are usually food-grade. Just line them with landscape fabric to keep soil in, and make sure they have drainage holes (most do).

How many plants can I grow in one crate?

It depends on the plant. For leafy greens, you can fit 6–8 plants per crate. For larger plants like tomatoes or peppers, only 1–2 per crate. Root vegetables like carrots need about 3–4 inches of spacing, so you might fit 5–6 carrots per crate.

What is the best soil for a crate garden?

Use a high-quality potting mix, not garden soil. Potting mix is lighter, drains well, and is sterilized to reduce disease. Look for a mix that contains peat moss or coconut coir, perlite, and compost.

Do I need to add fertilizer?

Yes, because potting mix has limited nutrients. After the first month, fertilize every 2–3 weeks with a balanced liquid fertilizer. Follow the label instructions for dilution.

How much sun do vegetables need in crates?

Most fruiting vegetables (tomatoes, peppers, beans) need at least 6–8 hours of direct sun. Leafy greens can tolerate partial shade (4–6 hours). If you have less sun, choose shade-tolerant crops like lettuce and spinach.

Can I grow a garden in two crates indoors?

Yes, but you’ll need a sunny window (south-facing) or a grow light. Indoor conditions are drier, so you’ll need to water more frequently. Choose compact herbs and microgreens for the best results.
