Delphinium is a plant with magnificent flowers that quickly conquer the hearts of all flower lovers. And while other houseplants impress with their foliage splendor, in the case of the amaryllis ( Hippeastrum ), as it is also still called, it is precisely this flowering that always tempts you to buy. Because many do not know how you should continue with the care after the flowering phase, respectively, what is necessary to bring the amaryllis to bloom again. The flowering phase is only promoted if the amaryllis care in the fall is right, and today we summarize what you should consider.

The importance of the dormancy phase for the delphinium
In autumn, right after the growth period from May to July, the amaryllis is in the resting phase and this should not be underestimated at all. Only if you “allow” her to go through this period of rest, you will also be rewarded with the long-awaited flowering in the winter. But you can and should help the delphinium to go into dormancy, which ideally you should start as early as August. If not, do it as soon as possible.
Initiate the dormancy phase in August
In principle, you only need to change the amaryllis care in the fall, so to speak, to mimic the seasons as it is known from the wild. In this case, that means that:
- You no longer water as frequently.
- no longer fertilize.
Starting in August, you gradually reduce the amount of water you give. Then, towards the end of the month, stop watering completely. You do not need to fertilize the plant at all from August onwards, because fertilizer stimulates growth and this is exactly what you want to avoid, after all, so that the delphinium can rest. You do not need to change the location. Ideally, your plant will be in a semi-shaded place in the garden, which is pleasantly warm.
Should you cut the amaryllis?
You’ll notice that the green leaves begin to wilt in the fall as a result of altered amaryllis care. We admit, it is not a pretty sight and surely you are tempted to cut them off. However, you would be depriving the plant of important nutrients, which is why we advise against it. Instead, let nature take its course, as this will allow the nutrients contained in the leaves to reach the bulb, which will benefit the later flowering.
Amaryllis care in autumn – What follows from September?
Now it is important to guarantee a temperature for the amaryllis that will allow it to go into dormancy. This is best between 10 and 15 degrees, and the new location should be dark. This is the moment when the plant should completely stop growing and you can also cut off the leaves. From now on, you do not need to worry about the delphinium any further and temporarily leave it to itself.
When do you “wake up” the delphinium again?
Just as you helped the amaryllis plant to fall asleep, you should naturally bring it out of dormancy again. After all, you are playing the role of Mother Nature right now. All you need to do for this is to repot the bulb . The fresh substrate will wake it up, so to speak, so that it can then begin the growth phase. The right time for this is November. Also do the following:
- Choose the right pot size: between its edge and the outermost edge of the bulb should be no more space than for a thumb.
- The bulb itself is not completely buried: A third or maximum half is above ground.
- From now on, the pot is best placed in a warm and bright place (eg, the windowsill).
- Keep the soil slightly moist, but avoid waterlogging.
- Do not fertilize yet. As soon as the first leaves appear, you can start fertilizing the plant, as usual, and in this way make the amaryllis bloom again.
Amaryllis care quick guide – The most important things once again summarized.
If you follow the aforementioned tips for amaryllis care tips for amaryllis care in the fall, the magnificent flowering should occur from about mid-December, so that you already have a beautiful ornament available for the Christmas season, which should give pleasure throughout the winter. We summarize the most important things again briefly and succinctly below:
- Gradually reduce and completely stop watering
- Stop fertilizing
- Remove wilting leaves only when they have completely dried up
- Cooler location between 10 and 15 degrees
- Dark location
- Cut off leaves
- Do not fertilize or water anymore!
- Repot bulb: circumference of pot only slightly larger than that of bulb; plant bulb partially above ground
- New location in light and warm
- Keep soil moist
- Fertilize from the first leaf formation
Tip: Now in the fall is also the perfect time to get new amaryllis plants. These are pre-cultivated and will bloom just in time for winter .
