I Have Noticed Just Recently That My Newly Planted Annuals…
Veronica Asked
I have noticed just recently that my newly planted annuals are not doing so well, so I fluffed the mulch around them only to find the nightly watering I do is not getting down to the roots. The perennials that share the same beds have been doing really well. The mulch I have down is just regular mulch.
The Gardener’s Answer
Hi, Veronica: Watering our annuals is crucial for their success. This is especially true in the extreme heat we have had early this season. Annuals in the ground may require less moisture than those in containers but until they develop a larger root system they will likely need to be watered three to four times a week depending on rainfall amounts. If they get a good soaking rain they should not need to be watered daily. Ideally watering should be done in the morning or afternoon while the sun is still out and the foliage can dry off before nightfall. When we water at night the foliage does not have a chance to dry off and fungal problems are more likely to occur. As far as your perennials, they will not require as much moisture as your annuals will since they have established root systems that can find water further down in the soil. Overhead watering with a hose is usually how annuals get watered in the ground. This is fine as long as they receive enough moisture but if you have a nozzle with a soaker option this would be great. This option helps the water to be released in a concentrated area as opposed to the regular shower spray that randomly sprays droplets of water. So next time you water, make sure to give your annuals a good soaking. Feel the soil to be certain before rolling up your hose. The mulch will help keep the moisture in but make sure it is not too thick; it should only be 2 inches thick. Otherwise it’s hard for the water to reach the root system and too much mulch can create an environment for insects and disease to live. Your annuals will also benefit from a slow-release or water-soluble fertilizer
