DESCRIPTION HOW TO GROW FROM SEED To successfully grow the seeds you need a half and half mixture of peat and horticultural sand that makes an excellent, well-draining medium. You can also use a combination of sand, compost, and perlite. The idea when growing aloe from seed is to provide loose material that won’t get soggy. If you are in a warm climate, you can grow the seeds outdoors. Keep the medium moderately moist either way in bright light and where temperatures are ideally 23 Degree Cels
