The gladioli thrip, a very tiny, black, winged insect, is a real threat to Gladioli flowers and plants. It sucks the juice from the plant, leaving a silvery appearance, eventually causing the plant to turn brown. Gladioli thrips also cause deformed flowers and prevent flower spikes from opening.
Why does Gladiole suffer?
Gladiole suffer when forced to compete with weeds. Remove the weeds. The new corm and the new roots are formed on top of the old one during the growing season. Deep cultivation when near the roots breaks off the new roots and slows up growth. Thrips cause deformed flowers and prevent flower spikes from opening at all.
Stage 1: Proliferation (Rooting)
The root system is one of the most important aspects of a plant’s survival and growth. The roots provide stability to the plant while growing, and they absorb water and nutrients that will help with its growth.
Stage 2: Proliferation (heading)
At this time, the plant should be kept in moderate to bright sunlight but no direct sun because it needs to produce its foliage or flowers during this phase.
Stage 3: Proliferation (flowering)
When it’s ready for flowering, which is usually about two months after proliferation (heading), it should be in full sun all day long with no shading. It needs lots of light available because there will not be enough energy to produce flowers without enough sunlight.
Stage 4: Flower development (stretch)
After all that growth, now through stretching, it’s time for your plant to produce its flowers. Although there are still some leaves on the flower stem at this stage, these will soon be shed as it develops.
Stage 5: Flowering (bud formation)
The good news is that your flower heads are now beginning to appear! But now, we need to start encouraging those flower heads into forming buds by keeping the plant in a cooler, dark place with less water.
Stage 6: Flowering (flower development)
There are now flowers on your plant! To encourage more bud formation and increase the chances of good coloring, reduce watering, keep the plant in the dark place, and reduce fertilization.
Stage 7: Flower development (deadheading)
Once you’ve removed your spent blooms, don’t stop removing them until the plant produces new flowers. This helps encourage more vigor and flowering later in summer; we call it rejuvenation, which means removing spent blooms before they turn brown.
How to grow gladiolus?
