I been growing aloe vera in containers for years.. I live in SW Virginia.. I always plant them in a clay pots with an all purpose soil that drains well.. In the winter time you need to put them by the window that gets the most sun (high light)... It needs at least a half a day but will adapt to less.. I set my plants outside in the spring two weeks after the last frost and water as need.. Be sure not to leave in standing water and let soil dry completely before watering again... Best temperatures are 70* days and 50* nights.. Be sure to that the frost doesn't get to it in the fall The plant will eventually grow sprouts (offsets) and should fill out the whole container.. When I transplant, I just pull of small sprouts (offsets) with roots and transplant in small clay pots.. One good size aloe can make many plants in a small time under proper conditions.. The most common problem is overwatering because it causes the plant to rot.. Aloe plants are like a cactus It's ok to lightly fertilize in the late summer/ fall.. The leaves may be plain green, variegated, or spotted with white or gray... The leaves will turn a brownish color if left out in full sun, during the summer, (8hrs of full sun)... if that happens just relocate the plant to another location with less full sun.. Sometimes in bright light plants may produce spikes of orange, yellow, or red fowers in the fall to winter... Plants can grow 2 ft tall and have thick leaves, (sometimes 3'' wide) filled with gel-like juice Aloe will grow if neglected...
