Keeping this in view, can mums get too much water?
Water, But Not Too Much Mums do not like to get dry. When their leaves are drooping, which can happen incredibly quickly, they are way too dry. Try to water them before they get to that point.
what time of day do you water mums? Slowly add water to the soil around the mum with a watering can, hose or sprinkler. Morning is the best time to water, as this will allow the leaves to dry in the sun. Water left to sit on the leaves can encourage fungal growth. For this reason, water as close to ground level as possible.
Correspondingly, how long do potted mums last?
Garden mums may be grown in containers, or planted in beds with existing shrubs and flowers. Flowers generally last about two or three weeks, depending on the outdoor temperatures and how far along the blooming process was when the plants were purchased.
Should you deadhead mums?
Deadhead mums in late spring to mid summer. This is right before blooming season, so the flowers have time to branch off from the cut stems. If you are growing your mums in a greenhouse or indoors, you can deadhead them as soon as you see dead growths since the mums won't be exposed to cold weather.
