Establishment
4-8 weeksYoung plant develops a small root system and 2-4 true leaves; growth is slow but steady
Keep soil consistently moist but not waterlogged. Use diluted fertilizer monthly. Begin gently acclimating to target light conditions.
Vegetative Growth
Ongoing, 6+ monthsPlant develops multiple stems or trails, with increasingly larger heart-shaped leaves; vining or bushy depending on variety
Water regularly when top soil dries. Apply balanced, diluted liquid fertilizer every 2-3 weeks during growing season (spring/summer). Prune to encourage bushiness or train vines.
