When to Plant Summer FloweringMost summer flowering bulbs can be planted in spring once the chance of frost has passed, which gives you plenty of time to pick the best matches for your creative goals and garden conditions. You might wonder why summer bulbs go into the ground in spring, while fall bulbs go into the ground in fall. The difference is in the structure of the bulb itself.
Plants like cannas and lily-of-the-valley are not actually bulbs in the same way that tulips and daffodils are bulbs. These plants grow from rhizomes or tubers. For that reason, they generally don't need a cold period in the same way that bulbous plants do, and they need more energy to protect themselves over the cold winter.
Wait until after your region's last frost date to plant your bulbs. Most summer bulbs should go in the ground after all threat of frost has passed. For Zones 3 and 4, you should plant summer bulbs in June. Hardiness Zone 5 allows for planting around Memorial Day, while Zone 6's final frost date is around Mother's Day. Hardiness Zone 7 gardeners can plant in late April. Gardeners in very warm climates, including Zones 8, 9, and 10, should plant as early as mid-March.

How to Plant Summer Blooming BulbsPlanting methodology for summer-blooming bulbs differs greatly by species and by bulb type. Planting lily rhizomes may look a bit different than planting gladiolus corms. However, there are a few major rules to abide by while planting summer bulbs.
How to Care for Summer Bulbs during SummerBecause summer bulbs do most of their growing during the hot season, they have somewhat needy watering requirements. Allow the soil to dry out between waterings, but do water your summertime bulbs regularly, and soon after the soil goes dry.
Some bulbs do not require much fertilization, but summer bulbs tend to have large leaves and heavy flowers that can use a bit of a boost. Most of these flowers come from tropical locales with rich soil. Fertilize monthly with a balanced fertilizer for maximum blooming.
Keep an eye out for pests and slugs, which are known to eat the leaves of tender summer plants. Slug bait can keep slimy slugs and snails away, and neem oil is a wonderful, all-natural insect repellent.
How to Care for Summer Bulbs over WinterMost summer bulbs, including tender gladiolus, dahlia, elephant ears, and tuberose, need to be lifted in the winter. They won't survive in freezing ground, or in temperatures below a certain threshold. Check your zone and your plant's heat requirements, and decide whether it makes sense to lift your bulbs in winter. Summer bulbs can be kept indoors in their containers, using a heated greenhouse or a non-freezing garage. Or, lift the bulbs themselves from the ground, and allow them to cure on sheets of brown paper for a few days before storing them in breathable material, and cool-but-not-freezing temperatures, for the winter.
