You've got some new Bamboo plants.
Wet the roots thoroughly, if necessary soak the whole root ball in water until it's saturated. Soak it overnight if possible. It can sit soaking in water for days. If the foliage doesn't look perky after about 4 hours of soaking, spray the leaves with water, and consider enclosing it with sheet plastic.
If the leaves are dry & tired looking, don't worry yet. Leaves will grow back if the rhizomes, roots & stems are OK. Even if your plants were cooked in moving --- it happens--- cross your fingers - soak the plants - many a toasted bamboo has made a wonderful comeback. Bamboo leaves are fragile & temporary, but bamboo roots and rhizomes contain the heart & soul of the plants.
If the permanent planting location is not ready to receive plants, plant them in pots or heel them in by covering the roots with soil and keep them well watered and in shade. We have kept plants unplanted like this for MONTHS with no ill effects. If they aren't too big & you have the strength, move them around in the landscape to see where you want them. It would be better to protect them from direct hot tropical sun until their roots are well-watered into their permanent location.
When planting in a permanent location or in a pot make sure the roots will be kept moist but drained & the pot or hole is somewhat larger than the root mass so the roots don't have to be rudely crammed into their new home. Handle them as little as possible. Plant them a little deeper than they have been growing in a pot or previous location, being sure to cover them with earth and NEVER DRY OUT! To dry them is to fry them!
Soil type doesn't matter much as long as it is soil rather than concrete or pure sand. Don't fertilize with chemicals. Bamboo is a vigorous plant but the roots can be burnt with chemical fertilizers. Potential improvement in growth with fertilizer is small. But the potential harm to the root system is great. Don't do it. The important thing is to keep bamboo rhizomes moist, even to the extent of turning a drip system on low at the beginning of the growing season, letting it drip day & night & not turning it off until the end of the season.
After plants have been established in the ground or in a large pot the canes should be thinned out yearly if you want large canes widely spaced. The thinning should be done in late fall or early spring. At that time each year small canes, leaning canes and deformed canes should be cut at the base using a sawzall or small hand saw and removed from the plant. If this yearly maintenance is not performed the plants will become a tangled rat nest of all size canes pointing in all directions and quite ugly.
That's it - no other maintenance is required, except to keep the plants watered.
