How to grow mangrove trees in Minecraft: a step-by-step guide
To grow mangrove trees Minecraft, you plant mangrove propagules, not saplings, on a suitable block with enough light and space. Mangrove trees were added in the 1.19 Wild Update, and they grow from these small, teardrop-shaped propagules that hang from the leaves of mature mangrove trees.
What you need to grow mangrove trees
Growing a mangrove tree requires a few specific conditions. You need a mangrove propagule, a valid planting block, a light level of 9 or higher above the propagule, at least 6 blocks of clear vertical space, and a roughly 5x5 horizontal area around the base for the roots to spread. The tree also needs solid blocks nearby for its roots to land on below the propagule, mud does not count as solid support for roots. If you plant over a large hollow space or over unsupported mud, the tree may fail to grow.
Step 1: Find a Mangrove Swamp biome
Mangrove trees grow naturally in the Mangrove Swamp biome, which is a warm variant of the standard swamp. You can identify this biome by its light-green foliage, teal water, and mud-covered ground. Mangrove swamps often appear near jungles or deserts, so exploring around those areas can help you locate one. If you're having trouble finding a mangrove swamp, keep exploring, these biomes generate in most Minecraft worlds, and the distinctive colors make them easy to spot once you know what to look for.
Step 2: Collect mangrove propagules
Mangrove propagules hang from the leaves of mangrove trees in the Mangrove Swamp biome. To collect a propagule, simply break it, no specific tool is required. You can also wait for mangrove leaves to decay naturally, which will drop any fully grown propagules attached to them. Propagules have four growth stages, and only fully grown ones drop when broken. Another way to obtain mangrove propagules is by trading with a Wandering Trader, who sometimes offers them in exchange for emeralds. Once you have a few propagules, you're ready to plant them anywhere you like, mangrove trees can grow in any biome, as long as the planting conditions are met.
Step 3: Choose and prepare the planting spot
Mangrove propagules can be planted on a variety of blocks: mud, dirt, grass blocks, coarse dirt, podzol, mycelium, rooted dirt, moss blocks, farmland, muddy mangrove roots, or clay. Choose your spot and clear a 5x5 horizontal area around the planting location, removing any vegetation or obstructions. You also need at least 6 clear blocks of vertical space above the propagule. If you're planting indoors or underground, make sure the ceiling is high enough, or use bone meal to force growth in tighter spaces. The smallest viable planting box is 5x5x5 blocks, though trees can reach a maximum size of 13x13x18 blocks if given enough room.
Step 4: Plant the mangrove propagule
With your spot prepared, select the mangrove propagule from your inventory and right-click on the ground to plant it. You can plant propagules underwater, they grow fine submerged. Ensure the light level is 9 or higher above the propagule; sunlight works outdoors, and torches can provide sufficient light indoors. After planting, you or another player must stay near the propagule for it to grow. If you wander too far away, the growth process will pause until someone returns.
Step 5: Speed up growth with bone meal
If you don't want to wait for natural growth, you can use bone meal on a planted propagule to instantly grow it into a full tree, even in low light conditions. When the tree grows, it generates mangrove roots below and around the trunk. Any mud blocks in the way of the growing roots will be converted into muddy mangrove roots blocks. This conversion is automatic, you don't need to do anything extra. Bone meal is especially useful if you're growing mangroves in a confined space or underground where natural light is limited.
Troubleshooting mangrove tree growth
If your mangrove propagule isn't growing, check the basics first. Insufficient light is a common issue, make sure the light level is 9 or higher above the propagule. Blocked vertical space is another culprit; clear at least 6 blocks above the planting spot. Lack of solid root support can also prevent growth, remember that mud alone doesn't count as solid support, so the roots need to land on solid blocks like dirt or stone below the propagule. In Java Edition, log and wood blocks directly above a propagule do not prevent growth, unlike other solid blocks. In Bedrock Edition, however, log and wood blocks above a propagule will prevent its growth. If your propagule doesn't grow after one in-game day (20 minutes in real time), it may need to be replanted in a more suitable area. Check the space, light, and support conditions, then try again, mangrove trees are forgiving once you meet their requirements.
