Every gardener knows the feeling: you've carefully planted something new, watered it faithfully and given it plenty of care, only to find that the flowers never to appear.
It can be disheartening when all that effort doesn't reward you with a display of blooms. The good news, however, is that the situation is often salvageable.
The first step is identifying the root of the problem. From unusually warm weather and incorrect pruning to unrealistic expectations about when a plant should flower, there are several possible reasons blooms fail to appear. Here are four of the most common culprits.
1. Your plant needs more time to establish
Some plants simply take longer than others to start flowering. According to the Royal Horticultural Society (RHS), newly planted flowering shrubs and trees often spend their first few seasons directing energy into developing roots and shoots, rather than producing blooms.
Some shrubs can take several years to establish fully, but once they've laid down a robust root system, they'll reward you with a spectacular display. After all, patience is one of a gardener's greatest virtue.
The same applies to mature plants that have been moved. Even if a shrub flowered reliably in its previous position, transplanting can temporarily interrupt blooming while it re-establishes the roots to absorb enough water and nutrients, says the RHS.

2. You pruned at the wrong time
Pruning at the wrong time of year is one of the most common reasons why flowering plants fail to bloom.
"Pruning at the wrong time of year or in the wrong way can literally cut off dormant flower buds; the coming year’s flower display," cautions the RHS. "Hard pruning stimulates leafy growth instead of flowers, so keep pruning to a minimum if flowering is sparse."
Before reaching for the secateurs, make sure you understand the pruning requirements of the plant you're growing. Our pruning guides cover every everything from wisteria to roses, helping you cut back at the right time for the best display.
Also remember that if you have indeed pruned at the wrong time, you may have sacrificed next season's blooms, but the good news is that your plant will almost always recover.
3. Pests damaging your plant below the soil
You've dutifully planted dahlias, cosmos and zinnias only to be disappointed by a lacklustre display, hidden pests beneath the soil could be to blame.
"While warm weather encourages flowers to flourish, it can also create ideal conditions for pests that can weaken plants and reduce their performance," says a spokesperson for the organic pest control specialist Nemasys.
"Many flowering plants rely on strong, healthy root systems to support continuous blooms. But when roots are damaged by pests in the soil, gardeners may notice poor growth, wilting and fewer flowers."
One option is using naturally occurring beneficial nematodes to control the likes of sciarid flies, caterpillars and thrips. Simply mix them with water and apply with a watering or spray can, allowing the microscopic nematodes seek out and control larvae beneath the soil.
4. It's a poor-quality plant
Sometimes you can do everything right and still fail to see flowers. In that case, as heartbreaking as it may be, the problem may lie with the plant itself.
"Those with weak or non-existent root systems will take a long time to establish. Those bought in flower sometimes take a while to settle back into flowering mode," says the RHS.
The RHS also notes that some seed-raised plants never flower because of their genetic make-up. For more reliable results, the organisation recommends choosing healthy, well-grown cultivars with a proven track record of good performance.
