Celebrate our national tree holiday! Perfect as a gift-with-purchase or giveaway item for National Arbor Day (last Friday in April), Jonsteen’s Arbor Day Grow Kits provide everything needed to germinate a variety of tree species from seed. Every kit grows at least one tree, and, like all our Grow Kits, they're 100% guaranteed. Trees do so much to make our planet livable. Here’s a chance for you to promote Arbor Day and do something for trees!
