How to Germinate Aloe
Nearly 400 species belong to the genus aloe, including well-known and widely cultivated varieties such as Aloe vera. All species of aloe feature succulent leaves and a roughly rosette growth habit, although they differ in size and flower composition.
As desert plants, aloes grow best in warm, dry climates, but many are hardy to U.S. Department of Agriculture hardiness zone 10 to 12, according to Missouri Botanical Garden, and will thrive in most coastal and inland areas. Most species of aloe seeds germinate reliably from seed and will establish a healthy root system in just a few months; however, they must be kept warm and slightly dry to prevent fungal infections.
Mix Planting Soil
Combine 2 parts soil, 1 part perlite, 1 part sand and 1 part sterile compost in a bucket, advises the University of Florida. Stir the components while adding water. Add water and stir until the mixture feels moderately moist and takes on a uniform appearance. You can also opt for a commercial planting mix for succulents.
Prepare Nursery Flats
Pack the sand mixture into a 2-inch-deep nursery flat. Fill it to within 1/4 inch of the top. Press the surface to make it even and squeeze out any trapped air.
Plant Aloe Seeds
Lay out the aloe seeds 1 inch apart on the surface of the sand mixture. Push the seeds into the surface of the mixture with the flat of your hand. Cover the seeds with a very thin layer of sand.
Required Sunlight for Germination
Place the nursery flat on a large table or workbench where it will receive eight to 10 hours of sunlight daily. Shine a fluorescent lamp onto the nursery flat for eight to 10 hours daily if sufficient natural light is unavailable.
Maintain Warm Temperatures
Warm the bottom of the nursery tray with a heat mat set to 70 F. Keep the heat mat turned on at all times while the seeds germinate. Drape a sheet of plastic wrap over the nursery tray to help hold in the warmth. Remove the plastic wrap for a few hours to dispel trapped moisture whenever excess condensation forms inside.
Water Aloe Sees
Mist the aloe seeds whenever the sand mixture dries out in the top 1/2 inch. Avoid letting the sand dry out completely for longer than six to eight hours, but do not saturate it either.
Aloe Vera Germination Time
Look for sprouts in two to four weeks, depending on the species of aloe. Keep the nursery flat on the heat mat for two weeks after germination. Water by drizzling water carefully around each sprout instead of misting the seedlings with water, which can precipitate a fungal infection.
Transplant Aloe Vera
Transplant the aloe seedlings into individual 2-inch pots filled with the same growing mixture created in Step 1. Scoop the seedlings from the nursery flat using a spoon and transfer them into the pots. Water them with 1 tablespoon of water every three days and make sure the pot and soil allow for good drainage, advises PlantVillage.

Aloe Seed Propagation – How To Grow Aloe From Seeds
Aloe plants are one of the most beloved houseplants. These charming succulents are widely available and come in a variety of sizes. Propagating a favorite plant is usually done with cuttings, which produce viable plants more quickly than seed. However, growing aloe from seeds is rewarding, pretty easy, and can afford you the opportunity to have some exotic and rare plants in your collection. Below are instructions on how to grow aloe from seeds and increase your stock of these helpful plants.
How to Collect Aloe Seeds
Aloe plants must be four or more years old before they produce reliable seed. The exact time depends upon the species and some plants don’t mature for up to a decade. Once the plant is flowering, it is able to produce seed. You can harvest seed from spent flowers or order them from reputable dealers. In the former method, you need to know how to collect aloe seeds and save them.
Gardeners with mature plants have probably seen the seeds in the flowers after they brown and lose petals. What do aloe seeds look like? They are tiny, grayish brown to black and flat. Seeds that are light-colored or white are not ready to harvest and will not germinate.
Seeds are found in dried pods on the plant and need to be extracted by splitting the pod. Pods will be brownish-green when ready. Keep a basin under the pod to collect the seed and discard the empty pod.
Aloe seed propagation can begin immediately or wait until the following spring if sowing outdoors. Save seeds in a paper envelope in a cool, dark location. Seeds should be used within the year they were harvested for best results.
How to Grow Aloe from Seeds
Aloe seeds generally sprout quite easily. You need the proper medium and situation for better success. A half and half mixture of peat and horticultural sand makes an excellent, well-draining medium. You can also use a combination of the sand, sterile compost and perlite. The idea when growing aloe from seed is to provide loose material that won’t get soggy and is not prone to pathogens or weeds.
Any container will do, but flats use less soil and create a controlled environment for seedlings. Lightly dampen the medium and spread the seed about an inch apart. Cover them with a light dusting of the sand.
If you are in a warm climate, you can grow the seeds outdoors. The rest of us will need to start them indoors with the addition of bottom heat of some kind. Keep the medium moderately moist either way in bright light and where temperatures are ideally 75 degrees Fahrenheit (23 C.).
Care During Aloe Seed Propagation
Many growers put a plastic lid on flats or containers in plastic bags to keep humidity high for germination. Unfortunately, if you are using a non-sterile organic medium, this can lead to fungal issues that may kill your babies.
Mist the surface of the soil to keep it moist until you see sprouts. This may take 2 to 4 weeks depending upon species. Young seedlings should stay on a heat source for two weeks as they develop roots.
Watering from under the seedlings in an open flat prevents damping-off and gives the roots just enough moisture after they have been removed from heat mats. The most important thing when seedlings are still at the two-leaf stage is to prevent desiccation while not drowning the poor things.
Once four or more leaves are observed, pot each into 2-inch (5 cm.) pots with a sterilized mix of 3 parts organic material, 3 parts pumice and 1 ½ parts coarse sand. Grow on as you would adult plants.
