Growing tips

  • 1
    Thin to One Plant

    After germination, carefully remove extra seedlings leaving only the strongest one. Big greens need space to develop properly.

  • 2
    Harvest Outer Leaves Continuously

    Pick the largest outer leaves first, always leaving the center crown intact. Your plant will keep producing for months this way.

  • 3
    Keep 4-5 Leaves Minimum

    Never harvest more than a few leaves at once. The plant needs enough leaves for photosynthesis to continue growing.

  • 4
    Watch for Bolting

    If you see a tall center stalk forming, harvest immediately. Once big greens bolt, the leaves become tough and bitter.

Growth timeline

Follow these stages for successful growing in your Rise Garden

1
Days 0-5

Germination

Sturdy seed leaves push out of the pod to get your kale going, usually within about five days. Keep the nursery dome on and check your water daily while the roots build strength. A strong start sets up big, productive leaves later.

2
Days 5-12 moveintogarden stage

Move to Garden

Move your kale to the garden once it shows two or three true leaves. Keep the single strongest seedling and snip the rest off at the base, since big greens need room to grow large. It's now ready for nutrients and space to fill out.

3
Days 12-29 prune stage

Active Growth

Your Starbor unfurls tightly curled, deep-green leaves and starts building a full crown. You'll soon count six to eight leaves as the plant takes shape. Pull off any yellow or damaged lower leaves so energy goes to fresh, curly growth.

Day 42+ harvest stage

How to Harvest

Cut the outermost leaves at the base, always leaving at least four or five inner leaves and the center crown intact. The plant keeps producing for weeks as new leaves rise from the middle. If a tall center stalk shoots up, the kale is bolting, so harvest everything at once.

Growing FAQs

  • Place your seed pod in the Rise Gardens nursery tray with the label facing up. Add water until the pods are saturated, then place the grow dome on top to maintain humidity. Keep the dome on until you see sprouts emerging (usually 3-10 days depending on the plant). Once sprouted, remove the dome so leaves can develop properly.

  • Look for 2 sets of true leaves - these are the leaves that appear after the initial round seed leaves (cotyledons). At this stage, the roots are developed enough to absorb nutrients from your garden. For most plants, this happens 7-14 days after germination. Gently lift the pod from the nursery and place it in an empty spot in your Rise Garden.

  • Add nutrients once per week. Use Sprout nutrients for leafy plants and during the vegetative growth stage of all plants. Switch to Blossom nutrients when you see flowers forming on fruiting plants (tomatoes, peppers, etc.). The Rise Gardens app tracks your plants and sends reminders when it's time to add nutrients.

  • Yellow leaves usually indicate one of these issues: 1) Low nutrients - add nutrients if it's been more than a week. 2) Low water - check that water levels are above minimum. 3) Natural aging - bottom leaves naturally yellow as the plant grows; just remove them. 4) Too much light - ensure your plant is in the correct shade group position.

  • Yes, for most plants! Herbs and leafy greens are "cut-and-come-again" - harvest outer leaves or up to 1/3 of the plant, and it will regrow for multiple harvests. Fruiting plants (tomatoes, peppers) continuously produce fruit for months. Microgreens are the exception - they're harvested all at once and won't regrow.

  • Since there are no bees indoors, you'll need to hand pollinate tomatoes, peppers, and other fruiting plants. When flowers are fully open, use a small paintbrush or cotton swab to gently brush the center of each flower. Transfer pollen between flowers by touching multiple blooms. Do this every few days while plants are flowering.

  • Germination time is how long until you see the first sprout emerge from the pod - typically 3-10 days. Harvest time is when you can start picking from your plant - this ranges from 7 days for microgreens to 12+ weeks for fruiting plants.

  • Causes: Nutrient deficiency, overwatering, natural aging of lower leaves, or too much/little light.

    Solutions: Add nutrients if it's been over a week. Check water levels aren't too high. Remove naturally yellowing bottom leaves. Verify plant is in correct shade group position.

  • Causes: Low water levels, root problems, temperature stress, or transplant shock.

    Solutions: Check and refill water immediately. Inspect roots for brown/slimy appearance. Keep garden away from heat sources and cold drafts.

  • Causes: Insufficient light, low nutrients, overcrowding, cold temperatures, or pH imbalance.

    Solutions: Ensure lights are on 14-16 hours daily. Add nutrients weekly. Thin overcrowded plants. Keep garden in warm area (65-75°F).

  • Causes: Fungus gnats from damp conditions; aphids hitchhike on other plants or through windows.

    Solutions: For gnats: let pod surfaces dry, use yellow sticky traps. For aphids: spray leaves with water, wipe off pests, or use diluted dish soap spray.

  • Causes: Algae from light exposure to water, root rot from stagnant water, or bacterial growth.

    Solutions: Keep tank covered to block light. Ensure water is circulating properly. Clean tank between plantings. Trim brown, mushy roots.

  • Cause: Nutrient imbalance, water on leaves, or beginning of disease.

    Solution: Remove affected leaves. Avoid water on foliage. Ensure good air circulation.

  • Cause: Too warm, insufficient nutrients, or harvesting outer leaves too much.

    Solution: Keep garden in cooler area. Ensure consistent nutrient schedule. Leave center intact.
