helianthus are among the most commonly develop flora in the UK .

Many mass find those freehanded disc - influence flowers not only follow the sunlight but , in a manner , resemble it .

In fact , on tall varieties , those bright yellow rays against a down in the mouth sky are a deal to uplift a dispirited affectionateness .

However , sunflowers also give gardeners all over the world causal agency for business , as every now and again they sag !

Sunflowers can droop for any one of a miscellanea of reason , include :

a sunflower with a thick stem and no support beginning to topple over

Underneath we take you through these reasons so you may have the best chance at rectifying the issue .

1) Blooms Dying Back

Sometimes , what you are worried about is not a drooping plant but a dying blossom .

You need not do anything other than harvest the seeds at the appropriate time or deadhead the fading blossom .

2) A Lack Of Support

Some types of helianthus are top - heavy , mean their stems are not strong enough to keep upright under the weightiness of big efflorescence heads , so they droop .

This intellect for drooping is normal .

All you necessitate do is provide bread and butter to the plant by inserting a stake or cane into the ground and loosely tying the root to it , especially at its upper half .

Gardening Expert Dan Ori tells us inviolable but loose is the way to tie helianthus , particularly   near the top as the works will want to conform its position towards   the sun throughout the day . This cognitive process is call   phototropism .

For specific instructions please see our pathfinder onhow to support tall plant .

3) A Lack Of Water

Sunflowers are thirsty plants and insufficient weewee will make loll and wilt .

This problem , cater you have caught it in salutary meter , is not really a problem at all .

Simply give the plant a thorough watering with coolheaded water in the aurora , watering at the stain personal line of credit .

We only hope that you are not discover this problem and its curative on a hot , sunny good afternoon !

If you are , use cold wateror look until late evening . Keep the affected plants properly hydrate .

4) Pests Or Diseases

sunflower are mainly trouble - liberal flora .

However , they can occasionally succumb to pests and disease , especially when conditions are sub - optimal .

Crowding , a closed - in grow spot , overwatering , damp foliage and weeds increase the betting odds of pestilence attacks and disease .

The specific pest infestation or disease will have to be name and , if possible , treat .

5) Transplant Shock

Sunflowers do not take well to transfer for a multiplicity of reasons .

Even if you have been especially thrifty , helianthus roots are not adaptative to new conditions and begrudge being disturb .

Another factor is a sudden change in environmental conditions as a result of footling or no hardening off .

There is not much you may do except keep the plant well - hydrated and keep your fingers span .

If you have all of a sudden transplanted the sunflowers from a partially shaded spot to a spot in full sun , arranging a irregular barrier to provide shade during the afternoons may aid .

Going forward I suggest that you inseminate seeds directly in overt terra firma or , if you ’re not too deep into summer , why not do it now ?

6) Phoma Black Stem

Phoma bootleg stem is a fungal disease that can move sunflowers.1Phoma Black Stem . ( n.d . ) . National Sunflower Association . recall April 14 , 2023 , fromhttps://www.sunflowernsa.com/growers/diseases/phoma-black-stem/

Waterlogging due to overwatering , wretched - draining territory , consistently tone down foliage or overcrowding are contributing factors .

regrettably , there is no known cure.2Phoma Black Stem / Phomopsis Stem Canker . ( 2019 , July 22 ) . University of Nebraska - Lincoln . call back May 22 , 2023 , fromhttps://cropwatch.unl.edu/plantdisease/sunflower/phoma/phomopsis

The stricken plants will have to be uprooted and cast out of .

This fungus often lives in the territory , so it would be wise to reset the reason and grow something robust in that spotlight instead in the futurity .
