Tulips like the sun and do best in places with much light. They need at least six hours of direct sun daily. In regions with higher temperatures, a bit of light shade works for them and even afternoon shade can help the flowers stay fresh more long.
When tulips lean down or do not seem to flower, they commonly lack sunshine. Too much sun however can hurt the leaves by burns. The ideal is light quite strong to grow healthy flowers, without risk to burn the plant.
How to Grow and Care for Tulips
Tulips need ground that drains well. In wet soil they easily rot and hardly form roots. The best way is to plant them in a sunny place with good drain.
Under leafy trees or in half-day solar areas they also can grow well. Tulips adapt well in the USDA Hardiness Zones of 3 to 8.
The bulbs are planted in the soil at the start of October, in about 20 centimetres of depth. Groups with odd numbers, as three, five or seven, look nicer than lines. Tulips in full sun reach their biggest height and flower size.
Through sunlight the leaves bring energy to the bulb for the next season. When the flowers fade, you cut the old parts and leave the leaves to dry naturally, because that helps to store energy in the bulb.
Tulips belong too the spring. First the leaves come from the bulb, later the flower appears, then it fades. They favour long, fresh and sunny spring.
Also the warmth matters, they handle early spring changes of temperatures, if only there does not come long cold during more than some days. In warm climates tulips hardly bloom again faithfully.
Some interesting species deserve attention. Meteoric Sun is a hybrid of the group Giant Darwin from around 1985. It shines in silver orange with rosy gloss and yellow center.
The stem is strong, and it has nice perfume. Novi Sun, hybrid of 2016 in golden yellow tone, has big flowers in form of cup, up to 15 centimetres broad, on stems of 55 to 60 centimetres tall. Its strong stems resist spring storms.
Solar Lover is a double tulip that changes its colour as it grows. It starts golden-yellow, later turns to tangerine orange and becomes deeper with scarlet strips. The stems reach 40 to 45 centimetres, holding flowers up to 10 centimetres broad.
There is also a species commonly called Eye of the Sun because of the yellow star in its centre.
For tulips cut in vases, remove the bottom leaves under the line of water, so that the water does not rot. Keeping the flowers away from direct sun and warm places, you helpsthem stay fresh more long.
