Growing tips

  • 1
    Be Patient with Germination

    Flowers often take longer to germinate than vegetables. Keep the dome on and maintain humidity - they're worth the wait!

  • 2
    Deadhead Spent Blooms

    Remove faded flowers regularly to encourage more blooms. This redirects energy from seed production to new flower growth.

  • 3
    Use Blossom Nutrients

    Switch to Blossom nutrients when buds form. The extra phosphorus helps produce larger, more vibrant flowers.

  • 4
    Cut Flowers in Morning

    Harvest flowers early in the day when they're most hydrated. Place stems in water immediately for longest vase life.

Growth timeline

Follow these stages for successful growing in your Rise Garden

1
Days 0-10

Germination

A pair of sturdy seed leaves pushes up from the pod to start your sunflower off. Flowers take their time, so expect sprouts in about ten days. Keep the nursery dome on and be patient while the roots build strength.

2
Days 10-17 moveintogarden stage

Move to Garden

Move your sunflower to the garden once it has two or three true leaves and stands steady. Handle it with care, since young flower stems can be fragile. It now needs room and nutrients to fuel its blooms.

3
Days 17-38 prune stage

Active Growth

Your sunflower builds a sturdy, compact frame, stacking up leaf set after leaf set. Clear away any yellowing lower leaves so energy heads upward. Give it plenty of bright light to keep growth stocky and strong rather than stretched and leggy.

4
Days - pollinate stage

Flowering

A round flower bud forms at the top, the promise of a cheerful golden bloom. Switch to Blossom nutrients now to fuel full, bright flowers. The bud may take one to two weeks to open, so keep up the light and patience.

Day 55+ harvest stage

How to Harvest

Cut blooms in the morning when they're most hydrated, snipping the stem at an angle. Place them straight into water to keep them fresh and perky. Deadhead any faded flowers to coax the plant into producing more.

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: Not enough maturity, wrong nutrients, or insufficient light.

    Solution: Be patient. Switch to Blossom nutrients when buds appear. Ensure adequate light.

  • Cause: Stress from temperature changes, moving plant, or water inconsistency.

    Solution: Keep garden in stable location. Maintain consistent water and nutrients.
