How to get Iris to Bloom Again: Why Iris Won’t Bloom 

Some irises grow from rhizomes while some other species grow from bulbs, both are underground reservoirs where growth processes are initiated for the iris to spring up and bloom afterward.

If something is wrong with the rhizomes or bulbs underground, then it will affect the production of fruits upwards. If the rhizomes or bulbs are rotten or not well-formed, healthy stems won’t sprout and that includes leaves.

Soil can also be another issue too, the iris plant needs a well-drained soil that receives ample sunlight so flowers can grow seamlessly. This also implies that if the plant is deficient of sunlight, it won’t bloom or it might lead to stunted growth. 

Another cause why the iris won’t bloom can be linked to the depth of planting. If the planting is too deep the iris will not grow flowers. 

Some other conditions that are precursors to the failure of your iris in blooming are overcrowding, unfavorable weather, insect infection, and plant diseases. 

But there is always a solution and that’s why you are reading this. So let’s get down to the meat of the subject.

How to get Iris to Bloom Again 

Here are some of the ways you can get your iris to bloom again:

Streamline Sunlight Conditions 

If the conditions surrounding your irises are shady, your iris won’t bloom. You can remedy such a situation by reducing the shades on your iris. Some species of the plant might need at least six hours of ample sunlight a day to blossom.

Anything you can do to allow for ample sunlight on your iris plant would do. From pruning other trees serving as shades to transplanting the iris to a new location where they will receive much sunlight would do the magic. 

Watch out for depths

When the depth of the rhizome or bulb is too deep, the iris will suffer for it. If you notice that your iris plant is not blooming, check the depth of the rhizome, if it is too deep, uproot and replants just beneath the soil.

In some cases like clay soil, a part of the rhizome should be above the ground. Clay soils are very rigid and won’t help the growth of iris, asking for blooming would even be too much of a demand. 

Reblooming Iris Watering Appropriately

Irises naturally do not need many efforts from you when it comes to watering, however, they should be watered every week following any successful planting season.

For irises that are rebloomers, you need to keep up with the watering through summer especially when there is less rainfall till they begin to bloom again. If there is drought, then you need to water generously. Water irises in a way that the water would permeate deep into the soil.

How to get Iris to Bloom Again: Get Rid of Faded Blooms

As part of paying attention to your iris, faded blooms are to be removed by cutting the stalks with a pair of scissors or hand clippers close to the base of the plant. Just like trimming flowers allows for better growth, beauty, and glory, the same goes for irises.

Removing faded blooms can help the iris plant conserve energy in their rhizomes which are to be utilized for blooming rather than exhausting them in the making of seeds. Faded blooms can still produce seeds but that will be at the expense of the energy that would have been used for blooming. For rebloomers, it can also lead to luxurious reblooming for them.

Reduce Overcrowding around the Irises 

The rhizomes are bound to expand with time and that will lead to some sort of clogging in terms of space around each other. They become too attached to each other and inhibit their successes.

You need to uproot the rhizomes and separate them from each other. After the separation which should be done with a knife, you can replant them as soon as possible. This should be done every three to four years, by then the rhizomes would have merged themselves together again leading to another crowding. They would bloom better after you’ve succeeded in splitting them. 

Limit the competition from other plants

Plants can be very greedy at times in terms of mutual resources beneath the soil. If your irises are surrounded by other plants, it means the resources in the soil like nutrients necessary for growth and blooming would be limited.

Get rid of weeds, that’s a thumb rule already and every other plant that you feel might be shortchanging your iris in terms of resources under the soil. Some of the competition might lead to shades that limit sunlight. Your plants would respond to all of these unhealthy conditions by failing to bloom.

You can fertilize them 

They are plants and they need some ingredients to boost their growth and in the case here, their blooming. You can fertilize in early spring as soon as they start to grow and fertilize a month later after they would have bloomed brilliantly in summer. Follow descriptions on the application of the fertilizer to the latter and you would have nothing to worry about. 

Conclusion 

Irises can be brought back to life after they’ve failed to bloom for a season. This can only happen if you’ve checked all of the possible causes that must have led to their deterioration in blooming. Pest and diseases are not to be ruled out, you can consult an expert for professional solutions if this is the problem. Your irises would begin to bloom again if you apply everything you’ve read here.
