In spring we receive many compliments for the beautiful snapdragons growing in our garden. But to have tall fragrant snapdragons in the spring garden, you must plant them in the fall.
Snapdragons enjoy sunlight, but partial shade is best in the deep south. I have found my snapdragons to bloom best with morning sun and afternoon shade or a little filtered sun all day.
Snapdragons prefer a fluffy, nutrient-rich soil. When planting, mix in enough compost or humus to make a fluffy mixture that will not compact. This ensures good root growth which will in turn provide lots of top-growth and blooms.
Snapdragons are not very drought tolerant, so water weekly in the absence of rainfall.
