Growing Tulips

Be sure to start planning your tulip bed ahead of time. There are so many varieties and ways to plant your bulbs, that you should plan how you want to arrange your bulbs. Tulips grow their best in full sun and must have well drained loamy soil. Tulips are bulbs and are planted 4 to 6 inches into the soil. This can be a problem if you have a lot of water building up in the soil as this will cause the bulbs to rot. There is a lot of information available on how to plant and care for tulips available.

Many tulips are actually hybrid cultivars that are grown in home gardens ,as well as pot plants and as cut flowers. You will find many species that are easily grown in your area. Tulips are easy to care for once they are planted.

Soil Preparation and Planting of Tulips

You should dig your soil up to a depth of 8 to 10 inches and work in plenty of manure or compost and finish off with bonemeal. Bonemeal should be added at 3 oz.per sq. Yd.

Bulbs should be planted 4 in. Apart and in holes 4 to 6 inches deep during the months of September, October, and November. This will depend on the region of the country that you live in. You don’t want to plant the tulips too early and have them to begin growing prematurely.

Plant them firmly into your 4-6 inch hole and add your bonemeal before covering and watering them. Don’t water too much.

Lifting Tulips

Tulips can be lifted in June or July when leaves have died down and store in shallow trays in a cool, dry place until replanting time. The small ones that you dig up should be planted in a nursery bed with other small bulbs so they can grow and mature. They will not bloom if planted when they are small. The larger bulbs should be stored where they can be kept dry until the next planting season arrives.

Many people practice putting bulbs into the refrigerator about 6 weeks before they are to be planted so they can get use to the cool temperatures.

Tulip Diseases

Tulips will be effected by the ordinary pests and diseases that attack most plants, such as, aphids, caterpillars, slugs, mice, and gray mold. Bulbs have some particular troubles of their own.

Tulips may be damaged by a disease known as Botrytis Blight -'Tulip Fire', which causes leaves, flowers and stems to wither as if burned. They will have tan spots on the flowers or leaves. If this disease is troublesome, spray with folpet fungicide every 10 to 14 days from March to May, except while plants are flowering.

Eelworms (a nematode) sometimes infest bulbs causing distortion of leaves and stems. Such plant should be burned and the site not used for bulbs for several years.
