10 Dwarf Olive Tree seeds. Growing a potted olive tree indoors has become popular. One reason people are taking to olive trees as houseplants is that caring for olive trees inside is easy. These trees tolerate dry air and dry soil too, making it an easy-care houseplant. And the trees are attractive too. The branches are covered with narrow, grey-green leaves that have furry undersides. Summer brings clusters of small, creamy flowers, followed by ripening olives.
Start by cutting off one end of the outer seed coating; then soak the seed in fresh water for 24 hours. This helps speed up germination. Then sow the seed indoors using potting mix and a pot with bottom drainage that's placed near a sunny window, sow around 1cm deep and cover with soil. Expect approximately 40 days or longer for the seeds to germinate, keep the area watered while you wait. Whether seeds are in pots or in the ground, water them when the top 1 inch of soil dries out, applying enough water to moisten the seed. Once the seed sprouts, continue to water. This variety is self-pollinating so you may even get olive fruits if it is kept in ideal conditions in a warm sunny location.
