Container vs In-Ground Feeding for Potted Plants

Pots and beds get fed on nearly the same schedule. What changes is the unit you dose in, how fast nutrients leave, and how much soil life the growing medium starts with. Here is how the rules shift between a container and the ground, and where to start with each.

The Short Answer

The schedule is essentially the same. The product docs give pots and beds matching timing: Microbes monthly, Veg every 3-4 weeks in pots and monthly in beds, Bloom weekly while flowering, and Kelp It Real every 2-3 weeks.
The unit is what changes. Pots are dosed per gallon of water. Beds are dosed per 1,000 sq ft, with a water volume to mix it in where the docs give one. These are two separate rates, not a conversion.
The starting point is different. A pot is a small, closed volume that usually drains out the bottom, and bagged mix often starts close to sterile. A bed is a bigger buffer and usually brings some soil life of its own.
Pots need Microbes first. Veg and Bloom are built to feed soil biology, not replace it, so a pot of bagged mix gets Microbes before the powders.

Why Containers Behave Differently

A pot is a closed system with a small tank. Three things follow from that.

Limited volume. Roots fill the pot, so there is only so much mix to hold nutrients and water. Nothing else is coming in from the sides or from deeper soil.

Faster leaching. In most setups, water that drains out of the bottom carries some dissolved nutrients with it. The more often you water, and the more freely the pot drains, the faster this happens. Beds lose nutrients this way too, but a deep soil profile tends to buffer it.

Little living biology to start with. Many bagged potting mixes contain very little living soil life, and you can't tell from looking at the bag. Some products add inoculants, so check the label if you care. Our default is to treat a bagged-mix container as starting with close to none.

That last point matters for us specifically. Veg and Bloom are low-nitrogen on purpose. They are designed to feed soil microbes that supply much of the plant's nitrogen. In a sterile mix, that step is missing, and the formulas under-deliver.

Containers: What to Do

Inoculate on day one. New pot, new transplant, fresh mix: add Microbes the same day, then feed. Don't wait for the mix to settle or break in. The biology is what does the breaking in.
Mix in order. Water first, then Microbes, then the powder (Veg or Bloom).
Feed on the product's schedule, not on a hunch. Microbes is monthly, Veg is every 3-4 weeks, Bloom is weekly while flowering, and Kelp It Real is every 2-3 weeks. The feeding chart sets the exact amounts.
Match the feed to the stage. Veg from transplant through pre-flower. Bloom from flowering on. Kelp It Real works at any stage.
Watch the plant and your watering, not just the calendar. A pot that dries out quickly or drains fast may call for closer attention, since the water that leaves the bottom takes some nutrients with it. We don't publish a dose by pot size, so if the plant looks hungry, check the chart and your watering before adding more product.

In-Ground and Raised Beds: What to Do

Native soil usually has some biology already, though how much varies, and mulch and compost feed it. A bed is also a much bigger buffer than a pot, so changes tend to show up more gradually. The schedule is essentially the same as for pots; the unit is what changes.

Still inoculate. We don't tell growers to skip Microbes in the ground. You can't reliably judge from the surface whether your soil has enough of the right organisms, and Microbes starts working the day it goes on. That includes a brand-new bed or a fresh mulch layer.
Mulch and compost help the biology, not the schedule. In general, they keep soil life fed between applications, which is part of why a healthy, mulched bed often starts with more biology than bagged mix. More on that in our mulching guide.
Feed by area, in the water volume listed below. The in-ground rates are per 1,000 sq ft. Mix each product in the water volume listed in the dose rates below: Microbes in 10-20 gallons, Veg and Bloom in 2-5 gallons. We don't publish a water volume for Kelp It Real in beds. Its entry gives 1 tsp for a foliar application (onto the leaves) or 2 tsp for a soil application per 1,000 sq ft. That is all we publish.
Raised beds depend on what you filled them with. Filled with bagged mix, treat them like a big container: Microbes first. Filled mostly with native soil and compost, they sit closer to in-ground beds. If you're unsure, start with Microbes.

We don't publish pre-scaled doses for a single bed or row. The area figures are for 1,000 sq ft.

Dose Table by Scale

These are the product-doc rates. The chart lives at /pages/feeding-schedule.

Microbes

Pots (per gallon of water): 1-2 oz, drench at the base
Beds (per 1,000 sq ft): 4-6 oz in 10-20 gallons of water
How often: monthly in pots, monthly in beds

Veg

Pots (per gallon of water): 1 tsp
Beds (per 1,000 sq ft): 1-2 oz (2-4 Tbsp) in 2-5 gallons of water
How often: every 3-4 weeks in pots, monthly in beds

Bloom

Pots (per gallon of water): 1 tsp
Beds (per 1,000 sq ft): 1-2 oz in 2-5 gallons of water
How often: weekly during flowering in pots, weekly in beds

Kelp It Real

Pots (per gallon of water): 1/2 tsp
Beds (per 1,000 sq ft): 1 tsp foliar or 2 tsp soil application (no water volume published)
How often: every 2-3 weeks in pots, every 2-3 weeks in beds

A few honest notes on these rates:

The rhythm is the same, or close to it, for pots and beds. The one difference is Veg, at every 3-4 weeks in pots and monthly in beds.
The two scales are not a conversion. A per-gallon rate is how strong the water in your watering can is. An area rate is how much product goes on a given patch of ground. Treat them as separate instructions.
The chart lists Veg and Bloom at 1/4-1/2 Tbsp (3/4-1 1/2 tsp) per gallon, Kelp It Real at 1/4 tsp per gallon, and Microbes at 1-3 ml per gallon. Microbes in particular shows up as ounces in one place and milliliters in the other. We aren't publishing a reconciled figure here. Use the chart.
No acre rates here. This is for home-scale growing.

Where Growganica Fits

Microbes is the foundation for containers and a sensible first step for beds. It is a liquid, and the biology goes in before the powders.

Veg and Bloom are the feeds. They need Microbes, or established living soil, to work as designed. Veg covers vegetative growth, and Bloom covers flowering and fruiting.

Kelp It Real is the add-on that fits at any stage, including transplant. It complements the feeds and doesn't replace them.

If you have a plant in a pot, one question decides most of this: did the mix come with living biology? If you can't say yes, start with Microbes. A bed of healthy, mulched soil may start with more biology, but the same program applies.

Frequently Asked Questions

Do I feed pots more often than beds?

No. The product docs give pots and beds essentially the same schedule: Microbes monthly, Bloom weekly while flowering, and Kelp It Real every 2-3 weeks. The one difference is Veg, which is every 3-4 weeks in pots and monthly in beds. What changes is the unit you dose in, and how closely you watch a pot that drains fast.

How do per-gallon and per-square-foot doses relate?

They don't convert. A per-gallon rate is how strong the water in your watering can is, and it is the rate for pots. An area rate is how much product goes on a given patch of ground, and it is the rate for beds, per 1,000 sq ft. Treat them as two separate instructions and pick the one that matches your scale. We don't publish pre-scaled doses for a single bed or row.

Does potting mix have microbes?

Often very little, and you can't tell from the bag. Many bagged mixes contain little living soil life, and some products add inoculants, so check the label if you care. Our default is to treat a bagged-mix container as starting with close to none, which is why Microbes goes in on day one.
