Frequently Asked Questions

What is the cheapest way to start a container vegetable garden?
Fabric grow bags are the most budget-friendly containers — a 5-pack of 5-gallon bags often costs under $15. Pair them with quality potting mix, a seed packet of fast-growing crops, and a basic fertilizer. You can get started for as little as $35–$50 total for a small 3–4 container setup.
How much potting mix do I need for my containers?
A standard 5-gallon container holds about 0.67 cubic feet of potting mix. A 2-cubic-foot bag fills approximately 3 five-gallon pots. For 6 containers, budget for two 2-cubic-foot bags of potting mix.
Should I buy seeds or plant starts for my container garden?
Seeds are much cheaper per plant ($2–$4 per packet vs. $3–$7 per start) but require 4–8 weeks of indoor germination time. A good middle ground: buy starts for slow-starting crops like tomatoes and peppers, and direct-sow fast growers like lettuce and herbs from seed.
Which vegetables give the best return in container gardens?
Fresh herbs (basil, mint, parsley) offer the highest grocery value per pot. Cherry tomatoes are prolific and yield high grocery value per plant. Salad greens give multiple harvests. Avoid space-hungry, low-value crops like corn or melons in containers.
How much does a container garden cost in year two and beyond?
Year two costs drop dramatically because you already own the containers, stakes, and tools. Recurring costs are mainly potting mix replenishment (refresh the top half or replace 30–50%), new seeds or starts, and fertilizer — typically $30–$70 for a 6-container garden.

Is a Container Vegetable Garden Worth the Money?

Container gardening is one of the fastest-growing ways to grow your own food — no yard required. Between pots, potting mix, seeds, fertilizer, and plant starts, the upfront cost can add up quickly. This calculator helps you see your true investment and compare it against the grocery savings you can expect to harvest.

What Does It Actually Cost to Start?

A typical beginner setup with 6 containers growing tomatoes, herbs, and peppers runs between $80 and $150 in the first season. Fabric grow bags ($5–$12 each) are the most affordable container option. Never use garden soil in containers — it compacts and kills roots. Quality potting mix runs about $12–$18 per 2-cubic-foot bag.

How Much Can You Save on Groceries?

  • Fresh herbs (basil, mint, rosemary): A grocery bundle costs $2–$4 and lasts days. One plant provides fresh herbs all season — easily $40–$80 in value.
  • Cherry tomatoes: A prolific plant can yield 5–10 pounds per season. At $4–$6/lb at the store, that is $20–$60 per plant.
  • Salad greens: Cut-and-come-again lettuce gives 3–5 harvests per pot worth $15–$30 in greens over the season.

How to Reduce Your First-Year Cost

  • Start with fabric grow bags instead of ceramic or terracotta pots.
  • Grow from seed where possible — seed packets cost a fraction of nursery starts.
  • Focus on the 3–4 crops that deliver the highest grocery value for your household.
