Watering your chrysanthemums doesn’t have to be a difficult task. In fact, with a little bit of care and attention, it can be quite easy to keep them healthy and hydrated. Here are a few tips on how to best water your mums:

Morning Watering

As with most plants, water your mums in the morning. It will allow them to absorb the water before the heat of the day sets in.

No Overhead Watering

Water at the base of the plant, not overheard and onto the leaves. The roots are where the plant takes in most of its nutrients and moisture. Watering the leaves of the plant can cause fungal diseases like powdery mildew.

Water Deeply

When it comes to watering your chrysanthemums, watering deeply is best. But you don’t want standing water to form– It can lead to root rot. So, provide enough water to reach the roots and let the soil drain well. If there is a plate underneath your pot, remember to empty them out after an hour.

Keep the Soil Moist

To ensure your mums thrive, plant them in rich, well-draining soil. Keep the soil moist but not soggy, as excess moisture can lead to rot. Pay close attention to your soil during and after planting to be certain the moisture levels remain ideal.


Mulching your mum is a great way to conserve soil moisture and keep weeds out. Just spread the mulch around evenly, so your mum can enjoy all the benefits!

When taking care of chrysanthemums, a few general tips will help keep your flowers healthy and beautiful.

First, plant your chrysanthemums in an area that gets plenty of sunlight. These flowers need at least six hours of direct sunlight each day to thrive, so choose a spot away from obstructions like walls or trees. Secondly, water your chrysanthemums regularly. These plants prefer moist soil, so check it frequently and water as needed.

Lastly, mums are heavy feeders. The best times to fertilize chrysanthemums are right as new growth springs up and again around the start of August and during the spring. Pick a slow-release fertilizer for the best results. A balanced fertilizer will help your mums grow strong and healthy, so they can put on a beautiful display all autumn long.

Chrysanthemums add a splash of color to your garden and make everything look more cheerful. But what if you don’t have a lot of outdoor space? Or what if the weather isn’t cooperating?

Don’t worry! You can still enjoy beautiful mums even if you have to keep them indoors in pots. Provide them plenty of sunlight near a sunny window, but keep an eye on the temperature. If it gets too hot, you can always open a window or move the pot away from the direct sun during the hottest part of the day.

Water them regularly during the establishment phase, and then keep an eye on the soil moisture levels. If your mums start to dry out, water them well.
