Tulips Early Single Tulip Keizerskroon
- Time for planting
One of the earliest named tulips still in cultivation and unsurpassed for bedding, the scarlet blooms having an edge of golden yellow to give a striking bi-colour effect. Keizerskroon is classified as an Early Single Tulip which are known to be one of the earliest forms of tulips. Originally created by bredding the two species varieties T. gesneriana and T. suaveolens the Early Single Tulips keep their low habit of the their parents, with Keizerskroon measuring up at 40cm which is standard for this variety. Valuable for placing in beds and exposed gardens due to their comparatively short height this April flowering variety can also be forced with Keizerskroon being marked for forcing in the last week of January. It also holds an 'RHS Garden of Merit' award and First raised 1750 sports: 'Rex',('glory of limmen')
Tulips will thrive in almost any type of soil where there is reasonable drainage. During the growing season they like plenty of moisture but the roots must not stand in water. Be careful not to feed tulips during the growing season as this will produce 'leggy' plants. Plant from October until late December 4 inches deep and approximately 5 to 6 inches apart.
Tulip failures are mostly due to damage by slugs and snails. Apply a slug repellant immediately after planting and repeat at monthly intervals until the plants stand well above the ground.
Note: If you are using one of the many available bulb planters be sure that the soil in the whole planting area is well worked to prevent any sitting water at the bottom of the hole made by the planter.
For indoor culture the best time to pot is September or October in fresh soil or loam mixed with sand or leaf mould. Do not use old potting material. Place the pots in a cool spot in the garden and cover with 15cm of clean soil, leave until top growth has attained 8-10cm. Transfer indoors and keep in the dark in a temperature not exceeding 60 degrees Fahrenheit. In a fortnight they made be removed to the light and the temperature slightly raised.
