Summer flowering bulbs are warm-weather plants that can offer blooms throughout the hottest parts of the year. From day lilies to begonias, there are a number of summer flowering bulbs to choose from. Planting these bulbs is not difficult as long as you do so at the right time. Hardy bulbs can be planted earlier than tender bulbs. If you plant summer flowering bulbs at the right time, you will be rewarded all season.
Start tender bulbs, like elephant ears, indoors around April or May if you live in a cold climate. If you live in a warmer climate you can start them as early as March.
Fill a well-drained pot with potting soil. Place the bulbs in the pot at a depth of about three inches and cover with soil. Water the soil and place it in a dark, warm area with a temperature between 65 and 75 F.
Choose a place in your garden to plant the summer blooming bulbs. Some bulbs like full sun, while some prefer full or partial shade. Consult each bulb's preferences to choose a place that is perfect for the plant.
Improve your soil. Add compost or manure to your soil and work it in to a depth of six to eight inches before you plant summer blooming bulbs.
Plant hardy summer blooming bulbs, such as alstroemerias, outside once the last frost has passed. Dig a hole for the bulbs at a depth about three times the height of the bulb and space each hole about three times the width of the bulb.
Place the summer blooming bulbs in the holes, one bulb per hole, and cover with soil. Water the bulbs for two to three minutes.
Plant tender summer blooming bulbs outside once the soil temperature is 60 degrees F. Dig a hole for the transplanted bulbs about three times the bulb's height and space the holes three times the bulbs' width apart from each other.
Place the tender summer blooming bulbs in the holes with one bulb per hole and cover them with soil. Be sure the green sprouts are above the surface of the soil. Water the bulbs for two to three minutes.
