It\u2019s also important to prune some of the older canes right down to the ground \u2013 not just the ends of the branches. This allows new canes to emerge and encourages more vigorous blooming.<\/p>\n

4. Late Freeze<\/h2>\n

If the temperature takes a dive just as the buds are opening or while they are developing, you may find that they freeze in place and never open.<\/p>\n

An unusually cold winter can also take a toll on a shrub\u2019s ability to flower, and branches may die off or suffer frost damage.<\/p>\n

\n

You can inhibit the effects of excessive chilling and freezing by wrapping smaller shrubs in burlap when extremely low temperatures are in the forecast.<\/p>\n

In addition, if you water shrubs occasionally during the winter, when the weather is dry and the ground isn\u2019t frozen, they may be better equipped to handle a sudden deep freeze.<\/p>\n

Believe it or not, plants with water inside them are less likely to suffer freeze damage than those that are very dry.<\/p>\n

5. Old Plant<\/h2>\n

Shrubs that reach mature dimensions with infrequent pruning are likely to have a lot of old wood that no longer bears flowers, because they are slowing down in their old age.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

You can rejuvenate old plants with a deep pruning<\/a><\/strong>. Remove about one third of the plant by cutting old canes to the ground.<\/p>\n

Be sure to open up dense middles so that the shrub receives sunshine all the way to the ground.<\/p>\n

In a couple of years, you should have an abundance of fresh canes and blossoms.<\/p>\n

6. Premature Bloom<\/h2>\n

Sometimes the weather plays tricks on us, with a false spring or Indian summer. This can also fool the shrubs into thinking it\u2019s time to bloom.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

I\u2019ve had forsythia bloom sparsely in the fall, and then sparsely again the following spring.<\/p>\n

Off-season blooming may even result in no spring bloom, if enough buds have a chance to open in the unseasonable warmth.<\/p>\n

This is one cause without remedy, but it doesn\u2019t mean there\u2019s anything wrong with your plant.<\/p>\n

7. Too Shady<\/h2>\n

Ideally, forsythia thrives in a full-sun location. If it\u2019s planted in a shady spot, this may be the cause of few or no flowers appearing in spring.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

If you have a plant that isn\u2019t getting at least six hours of sunlight a day, consider moving it.<\/p>\n

If this is not feasible, evaluate nearby trees and shrubs to see if they may be pruned to allow more light to reach your forsythia.<\/p>\n

And remember the importance of sunlight for future plantings!<\/p>\n

Blooms You Can Count On<\/h2>\n

Knowing these seven reasons why you forsythia may not bloom takes the mystery out of the occasional disappointment and enables you to be proactive in most cases.<\/p>\n

\n

With the exception of premature blooming which you can\u2019t control, there are ways to avoid the other causes and foster the growth of thriving bushes flush with bright yellow blossoms that bid a cheery goodbye to winter.<\/p>\n
