Every single bud in your garden is like a little promise from your plants.
But, when these buds collapse for no reason, it may bring tears in gardener eyes.
So, What is Bud Blast?
Bud blast is a term used to describe flowers that have prematurely aborted before or soon
after opening that means premature bud drop off.
What Causes this premature Bud Blast in Flowers?
The good news is that the most common factors involved in this bud blast are environmental
factors and hence can be easily diagnosed and treated.
Just analyse the causes that I shall be listing out now and find out which one is fitting
to your plant and solve your problem.
So lets list out the causes of this problem one by one:
1.
Water stress: Improper watering causes a great deal of stress to plants.
Under watering may cause plants to redirect water from enlarging buds to the food-producing
areas of the plant.
This is an act of self-preservation by the plant.
And Over watering often leads to root rot, or other fungal infections that may destroy
the developing flower buds.
Now The Solution to this problem: Always water the plants when the top one or two inches
of the soil is dry, and add a thick layer of mulch to keep moisture levels more even.
You can watch my separate video on What is Mulching and what mulching materials you can
use for mulching your plants.
Find the link at top right corner of this video, but lets first complete this topic.
2.
Temperature Extremes - Extremes in temperature can influence the buds development.
When temperatures fluctuate, the plants get stressed and may respond by dropping their
buds and flowers in an attempt to survive or conserve energy.
Solution: Moving plants may correct the problem, If its winter, you can start covering them
with polythene covers by small making holes in them or you can also use some support sticks
or a garden trellis and then wrap around with a blanket or a polythene cover to provide
the correct temperature as required, specially in night time.
3.
Pest Attack: Pests also can cause bud drop specially in hibiscus.
Insects like Aphids are small, sucking insects that will cluster on the new growths and buds.
They are easily visible and can be easily diagnosed, and can be controlled with any
general-purpose insecticide.
You can watch my separate video on How to Control Aphids and Whiteflies after you finish
this video from a link at top right corner of this video.
If you cannot control organically, then use azathion or malathion organophosphorous chemical
spray to control these pests.
4.
Wrong Lighting - This is also connected with temperature extremes.
Light has a direct effect on how well the plant can produce food and survive.
Often, buds fail when high light plants are in low light settings and vice versa, that
is plants accustomed to low light situations may overheat in direct sun, causing buds to
fall off.
Move these plants to more appropriate lighting conditions.
One hint here is: Avoid direct sunlight exposure during noon, thats when the sun is at its
peak.
5.
Humidity - Insufficient humidity can interfere with proper bud development.
Also when humidity fluctuates considerably then it will lead to buds that drop off.
If you want to increase humidity, you can make a humidity tray and place your container
on this.
Simplest humidity tray consists of some small pebbles in a tray filled with water, which
can increase the humidity around the plant.
6.
Young Plants - Younger plants often lack the root structure to support blooms and this
might lead to aborted blossoms.
7.
Recent Repotting or Transplantation is another reason.
What you can do in this case is, pick any blooms off the plant to allow the root system
to develop better before permitting it to bloom again.
8.
Transportation of the plant : which can be another reason that can be considered for
buds falling off because of weakening due to the stress of transportation.
So there we have it folks, that was our episode on the reasons and solutions to the problem
of premature buds falling off.
