One raised bed, two very different crops: leafy greens that want leaf growth and tomatoes that go from leaf to flower to fruit. In a hot, long-season climate the feeding is the easy part. The heat is the hard part. Here is how we would feed a mixed bed from day one, with the chart doses, a monthly calendar and a worked example that shows why we do not publish a single per-bed number.
The Short Version
Put Microbes in the bed on day one. Feed the whole bed Veg once a month. When the tomatoes start flowering, switch the tomato side to Bloom weekly and stop Veg there. Add King Krustacean at the tomato roots for calcium. The greens stay on Microbes and Veg.
Mix by the feeding chart's per-gallon doses, listed below. The per-1,000-sq-ft rates in our product docs do not match the chart. If the chart disagrees with anything here, the chart wins.
A hot climate does not change the rates. It changes the watering, the mulch and how well tomatoes set fruit. We do not publish climate-specific rates or planting dates. Your local extension office knows your frost-free window and your variety list.
Bed Setup and Microbes
Veg and Bloom are low-nitrogen on purpose. They feed soil biology, and the biology supplies the rest of the nitrogen, which is why Microbes is not optional with either one. A new raised bed filled with bagged mix has very little native biology, and you cannot easily tell whether an older bed has enough. The default is to pair.
Start Microbes the day you fill or plant the bed. Do not wait for the compost or mulch to settle first. Breaking that material down is the job the microbes do.
Mix order for every feed: water first, then Microbes, then the powder. Bloom follows the same order.
In a hot climate, store the Microbes jug below 100°F and out of direct sun. A closed shed or garage can pass that, so keep it somewhere cooler.
The Leafy Greens Plan
Greens want leaf growth, which is what Veg is for.
- Microbes monthly.
- Veg monthly, at the same time.
- Nothing else is required.
Bloom is a flowering feed, and greens are picked before they flower, so they do not need it. King Krustacean's doc lists veggies and fruits as its use and calls its profile most valuable to calcium-demanding fruiting crops, which is why this plan puts it on the tomatoes. We do not publish greens-specific guidance for it, so leaving it off the greens is this guide's simplification, not a product restriction.
Through the warm months, expect trouble from heat however you feed. Many lettuces turn bitter and bolt when it stays hot, and tolerance varies a lot by variety. Shade cloth and a heat-tolerant variety do more than feeding. Our lettuce guide and Swiss chard guide cover variety and picking.
The Tomato Plan
Tomatoes need two phases.
- Before flowering: Microbes and Veg monthly, from transplant through pre-flower.
- At flowering: switch to Bloom weekly, with Microbes still monthly. The Bloom literature says to discontinue Veg and other nitrogen once Bloom starts.
King Krustacean is the add-on for tomatoes. Its doc names tomatoes as an especially good fit, and the guaranteed analysis shows 10% calcium. The chart dose is ¼ tablespoon per gallon, a tablespoon and not a teaspoon.
Calcium in the soil is only part of blossom-end problems. Uneven watering is a common contributor, so King K does not replace steady irrigation. We do not promise a result on any specific disorder.
Kelp It Real fits the hot climate. Its doc lists transplant stress and pre-heat-wave foliar applications as use cases. Spray in the early morning or evening, not midday sun. For the full crop picture, see the tomato growing guide.
The Numbers: Per Gallon First, Then Per Bed
Mix by the chart's per-gallon doses. The frequencies come from the product docs.
- Microbes: 1-3 mL (¼-¾ tsp) per gallon. Monthly in the bed, monthly in pots.
- Veg: ¼-½ Tbsp (¾-1½ tsp) per gallon. Monthly in the bed, every 3-4 weeks in pots.
- Bloom: ¼-½ Tbsp (¾-1½ tsp) per gallon. Weekly while flowering, in the bed and in pots.
- King Krustacean: ¼ Tbsp (¾ tsp) per gallon. Monthly in the bed, every 2 weeks in pots.
- Kelp It Real: ¼ tsp per gallon. Every 2-3 weeks, in the bed and in pots.
Worked example: a 4 ft x 8 ft bed (32 sq ft)
The docs also give rates per 1,000 sq ft, and this bed is 32/1,000 = 0.032 of that. Veg's rate is 1-2 oz (2-4 Tbsp) in 2-5 gal, which scales to roughly ⅕-⅖ tsp in 8-20 fl oz. As a strength, that is about 1.2-6 tsp per gallon, against the chart's ¾-1½ tsp. Microbes is further off: 4-6 oz in 10-20 gal works out to roughly 6-18 mL per gallon (reading ounces as fluid ounces), against the chart's 1-3 mL.
The area rates and the chart differ by a large factor, and the docs do not reconcile them. So we do not publish a single per-bed figure. Scale the chart's per-gallon dose to your watering can and water the bed with it as you normally would.
What to Do: A Monthly Calendar
- Day one: greens and tomatoes both get Microbes, then Veg.
- Each month before flowers: greens get Microbes + Veg. Tomatoes get Microbes + Veg, King K at the roots, and Kelp It Real every 2-3 weeks.
- First flowers: greens keep Microbes + Veg. Tomatoes switch to Bloom weekly, stop Veg, keep Microbes monthly and King K monthly.
- Mix in a watering can at the chart dose per gallon: water, Microbes, then the powder. Stir until dissolved.
- Apply to the soil at the base of the plants, then water in.
- Water early in the morning, so leaves dry and the soil holds moisture before peak heat.
- Mulch the bed. It slows evaporation and keeps the soil cooler. Keep it a little back from the tomato stems. More on that in the mulching guide.
- Give Bloom and King K to the tomato side, at the roots. The greens stay on Microbes and Veg.
- In a heat wave, do not push extra feed. Stressed plants in hot soil are a poor time to add more.
Heat also affects fruit set. Many tomato varieties drop blossoms or set little fruit when days run very hot or nights stay warm, and the thresholds depend on the variety. More Bloom will not fix a set problem caused by temperature.
Pots Versus Beds
Pots use the same products and chart doses per gallon: Microbes 1-3 mL, Veg and Bloom ¼-½ Tbsp, King Krustacean ¼ Tbsp, Kelp It Real ¼ tsp. The schedule shifts a little: Veg every 3-4 weeks and King K every 2 weeks, with the rest as in the bed.
Pots dry out faster than a bed, especially in heat, so they need water more often. Feed on the schedule, not at every watering. Bagged potting mix has very little native biology, so Microbes goes in on day one, the same as a new bed. A tomato in a pot follows the same stages as in the bed: Veg until flowers, then Bloom, with Microbes throughout. We do not publish a feed volume per pot, so give each pot a normal watering of mixed feed.
Where Growganica Fits
For this bed, the stack is Microbes and Veg for the whole bed, Bloom from first flowers on the tomato side, King Krustacean on the tomatoes, and Kelp It Real for transplant and pre-heat stress. Veg and Bloom both depend on Microbes.
You can look up your crop in the feeding picker. Check dose units there before mixing, since the chart is the source of truth.
Frequently Asked Questions
How do I feed raised beds with greens and tomatoes together?
Put Microbes in the bed on day one and feed the whole bed Veg once a month. When the tomatoes start flowering, switch the tomato side to Bloom weekly and stop Veg there. Add King Krustacean at the tomato roots for calcium. The greens stay on Microbes and Veg. Mix by the chart's per-gallon doses; if the chart disagrees with anything here, the chart wins.
Do pots and beds get different treatment?
Same products and the same per-gallon doses, with a slightly different schedule. In pots, Veg goes on every 3-4 weeks and King Krustacean every 2 weeks, with the rest as in the bed. Pots dry out faster, so they need water more often, but feed on the schedule rather than at every watering. Bagged potting mix has very little native biology, so Microbes goes in on day one, same as a new bed.
Is feeding different in a hot, long-season climate?
The rates are not. Heat changes the watering, the mulch and how well tomatoes set fruit. We do not publish climate-specific rates or planting dates, and your local extension office knows your frost-free window and your variety list.
