Gardeners urged to check 3 important signs now to help encourage dahlia blooms

Dahlias are a magnificent flower to have adorning the garden throughout summer, offering an array of brilliant hues spanning the spectrum. With a variety of shapes and sizes, dahlias can help illuminate outdoor areas right through until October.

Nevertheless, if you have recently planted several tubers and have yet to witness any development, there are a handful of indicators you ought to watch for to ensure the blooms are progressing properly. Gardening expert and TikTok creator Ish recently revealed the signs gardeners should monitor, and the remedies available should any problems arise. Ish said: "If you planted your dahlias two, three, even four weeks ago and they still look a little bit like this, don't be disheartened, it's actually incredibly common.

"But knowing the right signs will help you know if your dahlias are absolutely fine."

Should your dahlias have not emerged yet, these are the several factors you ought to be monitoring, and the ways you can help stimulate them to sprout in the coming weeks. There could be several explanations why the bulbs have not emerged yet.

The primary concern that might be impacting your plants is that the ground could be excessively cold. Ish clarified that dahlias flourish when there is a hint of warmth in the earth, reports The Mirror.

Should the ground be too chilly, the flowers will stay dormant or dramatically decelerate the plant's development. Gardeners should also examine the dampness of the earth. Ish said: "It also likes a consistent moisture, as well, in the soil. Not too soggy, but enough just so it can start soak it in, a rehydrate, and as a result, it'll thrive there too.

"But don't think it's not doing anything, it might still be generating roots underneath the actual tuber itself and getting itself started. But if you are worried, it's really easy to check."

To assess whether your dahlias have made any headway, simply brush aside the topsoil around the tuber and give it a gentle squeeze, ensuring it still feels firm to the touch.

Should the tuber feel soft and squidgy, it may have received too much water and started to rot. You might also discover some small nubs, which is a good sign of life.

Ish continued: "But don't panic. In the next few weeks, these will come up, you will have gorgeous dahlias and they will look fantastic. It's just a patience game."

Dahlia bulbs ought to have been planted in recent weeks, though planting can continue throughout May. Sprouting is a promising sign, and once they establish themselves, gardeners can expect to see blooms appearing from July through to October.

Once dahlias reach approximately 20cm in height, experts at Gardeners' World advise pinching out the primary growing tip to promote additional side shoots. The publication explained: "Remove the main shoot (in the centre of the plant, growing upright) down to the top pair of leaves, using a sharp knife or your thumb and forefinger."

Once your dahlias have bloomed, it is advisable to feed them every two weeks using a high potash fertiliser, such as tomato feed, to encourage a continuous display of flowers.

Additionally, ensure the plants are watered on a weekly basis. Deadheading is equally essential, as it plays a crucial role in extending the flowering period.

Gardeners' World advised: "The difference between buds and spent flower heads can be confusing - the buds are round, while spent flower heads are more pointed. Remove the whole flowering stem."
