I Have a Vegetable Garden. Now What?

So you’ve got a vegetable garden — or you’re about to. Excellent decision. This is the owner’s manual: seven questions, seven straight answers, zero fluff. Everything here is tuned for real gardens and real soil, with Florida reality baked in (because Florida soil has opinions).

🧰 What do I need?

The honest short list. You don’t need a garage full of gadgets — you need the fundamentals done well:

• Worm castings — your slow-release nutrition and microbial workforce. This is the one input that does the most jobs at once.
• Compost — the bulk organic matter that builds soil structure. Castings are the espresso; compost is the coffee. You want both.
• Mulch — wood chips, straw, or shredded leaves, 3–4 inches deep. Non-negotiable. Mulch holds moisture, feeds soil life as it breaks down, and keeps weeds from auditioning.
• A planting plan — what goes where, and when. (We’ll get to the “when” below. Timing is half the battle.)
• Water delivery — drip lines or soaker hoses beat sprinklers. Water the soil, not the leaves; wet leaves in humid air are a fungal block party.

That’s it. Fancy tools are optional. Healthy soil is not.

📏 How much?

For a vegetable garden: ½–1 cup of castings per transplant, mixed into the planting hole with the backfill. For beds: about 1 lb per square foot (roughly a ¼-inch layer) top-dressed at planting time, plus a mid-season side-dress of the same.

A 4×8-foot bed is 32 square feet — so one bed needs roughly 30 lbs of castings per feeding, which is conveniently about one of our 5-gallon boxes. Funny how that worked out. (It was on purpose.)

🛒 Which product?

For a vegetable garden, the Worm Castings – 5 Gallon ($50) is your workhorse. It’s the right size for beds, multiple plantings, and season-long feeding. The 1 Gallon ($20) is perfect if you’re running a couple of containers or want to try castings before committing — but a real veggie garden will burn through a gallon fast. Go big. Your tomatoes are counting on you.

🤲 How do I apply it?

Three methods, depending on the moment:

• In the planting hole: mix ½–1 cup of castings with the soil going back around each transplant. This puts nutrition and biology exactly where young roots find it on day one.
• Top-dressing: spread castings on the soil surface around established plants (about a ¼-inch layer), then cover with mulch. Watering and earthworms carry it down. No digging required.
• Side-dressing: mid-season, sprinkle a band of castings alongside each row or around each plant and water in. This is the second wind that carries heavy feeders like tomatoes and peppers through harvest.

What not to do: deep-till castings a foot down. The biology you want lives in the top few inches, and aggressive tilling evicts the earthworms and shreds the fungal networks. Gentle. We’re gardeners, not archaeologists.

📅 When do I apply it?

Three feedings a year cover almost every vegetable garden:

• At planting: castings in every hole + top-dress the bed. This is the big one — never skip it.
• Mid-season side-dress: 4–6 weeks after planting, when plants are sizing up fruit. Tomatoes, peppers, squash, and cucumbers especially thank you.
• Between seasons: when you clear a spent bed, top-dress with castings and compost before replanting. Every new planting starts with a fresh foundation.

Florida timing note: our main planting windows are late summer (for fall harvest) and late winter (for spring harvest). Feed at each planting, and your soil stays ahead of the game year-round.

🌱 What should I plant this month?

That depends on your zone and the month — and we’ve built exactly the tool for it. Punch in your ZIP code on our What to Plant and When page and it’ll tell you your USDA zone and point you to the month-by-month planting guide for it, with vegetables, fruits, flowers, and tasks for all twelve months.

The Florida cheat sheet: fall through spring is the main event (tomatoes, peppers, beans, greens, squash, carrots — the works). Summer is for the heat-built crew: okra, sweet potatoes, southern peas, Seminole pumpkins, and tropical spinaches.

🌍 How do I improve my soil?

The forever question — and the most important one on this list. Short version:

• Never leave it bare. Mulch, cover crops, living plants — pick one. Bare soil loses organic matter, dries out, and invites weeds.
• Feed it organic matter constantly. Compost for bulk, castings for biology, mulch for the slow drip. Every season, every bed.
• Grow cover crops in empty beds. Sunn hemp and cowpeas in summer fix nitrogen and shade the soil. Chop-and-drop before replanting — free fertilizer.
• Stop tilling aggressively. Disturb the top few inches at most. The soil food web is infrastructure — you don’t bulldoze infrastructure.
