Darwin Tulip Mix

Upon Arrival:

Plant the bulbs as soon as possible once you have received them. If you cannot plant the bulbs as soon as they have been shipped to you, remove the bulbs from plastic bags and put them on trays with damp peat moss or sawdust in a cool, well-ventilated place until you have a chance to plant them. Do not store them at temperatures below 4°C. Generally, all bulbs planted in the fall are hardy and do not need any special protection unless specified.

Where to Plant:

The most important rule when planting bulbs is to choose an area that is well-drained. Most bulbs will rot or deteriorate quickly where soil is constantly damp. Most bulbs thrive in full sun, or at least 5-6 sunny hours daily.

General Planting Info:

Plant bulbs individually by digging a hole for each bulb with a trowel or bulb planter, or place several bulbs on the bottom surface of a larger hole, then cover with soil. As planting depths and spacing varies depending on the type of bulb, refer to the cultural information found later in this guide. Be sure to loosen the soil at the bottom of the hole and work in a handful of organic fertilizer such as Veseys Bulb Fertilizer. Then press each bulb firmly into the soil, top pointing up and fill in the hole. When in doubt as to which way is up on a bulb, plant it on its side and let 'Mother Nature' decide!

Planting Tulips:

Plant tulips about 6” to 8” deep measuring from the base of the bulb. If you add mulch after planting, include this as part of your overall planting depth. Deeper planting (8"-12") will prolong the life of many of the later varieties, especially the Darwin Hybrids, for several years. Space bulbs 4"-6" (9 bulbs/squ.ft.-5 bulbs/sq.ft.) apart. If tulip bulbs send up leaves with no flowers, it’s time to replace them.

Growing:

Plant in full sun. At least 6 hours of direct sun per day. Though too much water is not good, sufficient water at the time of planting is necessary to get them growing and to ensure the start of a strong root system. Always grow tulips in well-drained and airy soil. Wet and/or compacted soil promotes fungus and disease and can cause bulbs to drown out due to suffocation. Adding compost or other organic matter to soil will make it drain better. We recommend raised beds in wetter areas and suggest that you have at least a 10” depth of loose airy soil. Proper soil drainage is very important when planting bulbs. After the tulips have passed their peak, remove the flower stalk to prevent seed formation and let the leaves die down normally. Leaves should be allowed to ripen for at least six weeks after blooming. This will help the new bulblets grow bigger. Fertilize in early spring or fall with a low nitrogen fertilizer such as Bulb Fertilizer or top-dress with rotted manure or compost.

Perennializing Tulips:

How well tulips grow in future years (perennialize) depends a lot on the cultural conditions in your garden. Tulips are indeed true perennials, but they need the cold winters and hot, DRY summers of their native foothills of the Himalayas, or the steppes of eastern Turkey. By choosing carefully among the wide selection of tulip varieties, you can enjoy successive bloom for at least six weeks. Do not water or fertilize during the summer.
