Some varieties of magnolia bloom earlier, others later. Overall, however, the flowering period of these stunning plants lasts relatively short, only a few weeks. In our latitudes, the first varieties begin to bloom in March, and other evergreen varieties, such as Magnolia grandiflora, even until June.

This beautiful ornamental shrub needs favorable conditions to bloom. You need a well-watered soil, a warm season and a lot of sunshine to achieve the best possible and longest possible flowering period. If you give your magnolia tree the best care possible, you could extend the blooming period as a result. During the blooming period, pay special attention to watering regularly so that the flowers don’t fall off too soon. Make sure there is no garden pathway over the roots that is highly trafficked, and keep the area above the roots as free of weeds as possible.


Magnolias the right soil

The optimal magnolia soil is a nutrient-rich, well-drained soil that has a neutral to slightly acidic pH. When planting this beautiful ornamental shrub, be sure to add organic compost to the soil and water it well. Make sure the root zone is as dormant as possible. That means removing weeds, not letting the garden path run too close to the plant, and also keeping possible underground pests away.

Magnolia flowering time: proper watering

Watering properly in the magnolia blooming season

Water your magnolia tree first once a week and then once a month for the next two growing seasons. If the magnolias are in more sandy soil, they will need less water than if they are planted in clay soil. However, then you will need a greater amount of water per watering. Plants that are watered incorrectly or not watered enough may produce shorter bloom times. Add a layer of bark mulch around the trunk of your plant to help keep the soil moist around the roots.

Cut back magnolia, or not?

Prune magnolias or not

Magnolias should only be pruned once in a while and rather irregularly. The need arises when you need to remove dead or damaged branches. Incorrect or too frequent pruning can cause the magnolia to become damaged or bloom less.

What factors can cause the magnolia tree not to bloom? If you were to approach the diagnosis systematically, the first and foremost question to answer would be: Is this the right climate zone for my magnolia species? Most magnolia species are designated for climate zones 7 – 9. They love warmth and direct sunlight. If temperatures are too low during the season, that could be why the magnolia is not blooming or the buds are not coming up. Also, late frost can cause the development of the flowers to be disturbed, and therefore it does not bloom at all.


If they can rule this out, see if their plant has enough sunlight, this is another factor. Magnolias will tolerate partial shade, but they bloom best when they have enough sunlight.

Soil quality

Another reason the plant may not bloom could be soil that is too low in nutrients. Check the soil quality, a soil test should reveal if this is the reason for non-blooming. The magnolia should have slightly acidic, humus-rich, nutrient-rich soil, with a pH of 5.5 to 6.5. Add appropriate organic fertilizers and the necessary nutrients to the soil for magnolias by doing the following: Drill small holes 30 cm deep, 15 cm apart, in the soil along the outermost line of the tree’s canopy perimeter. Add in the missing nutrients and then water well.

What care does the plant need after flowering?

You do not need to remove the faded flowers of the plant, as they fall off by themselves and form a beautiful carpet on the garden soil. Since magnolias are very sensitive to pruning, you should do this only if absolutely necessary. After the flowering period, you could see if there are some damaged or dead branches here or there and then remove them. It is important to be rather minimalistic about it. Otherwise, your magnolia may resent you and refuse to bloom beautifully again. We wish you a richly blooming and fragrant magnolia tree and much joy in your garden!
