Question 1

What is the optimal temperature for Cherry plum?

Accepted Answer

The best temperature for Cherry plum to thrive is 65~80℉(18~27℃). During the primary growing phase, the highest temperature tolerable would be 95℉(35℃), while the lowest tolerable temperature would be 15℉(-10℃). This species is tolerant of low temperatures and will survive freezing winters. The perfect, highest, and lowest temperature range:

Perfect：65~80℉(18~27℃)

Highest：85~95℉(30~35℃)

Lowest：-5~15℉(-20~-10℃) or below

Question 2

Should I adjust the temperature for Cherry plum during different growing phases?

Accepted Answer

Research shows that Cherry plum will begin to exhibit signs of stunted growth during prolonged periods of higher temperatures, especially during the development of axillary buds and the growth of main shoots. Keeping the temperatures consistent and cooler, around 65℉(18℃), will encourage vigorous growth after germination or transplanting.

Question 3

How can I keep Cherry plum warm in cold seasons?

Accepted Answer

Cherry plum can withstand freezing temperatures when planted in the ground in areas that don’t get below of 15℉(-10℃) as an extreme temperature during the winter months. But if planted in pots or containers, then their roots must be protected from the winter cold. Do this by wrapping the container in a blanket or bringing it inside where it will be fully protected from the elements.

Question 4

What damage will Cherry plum suffer if the temperature is too high/low?

Accepted Answer

Greater harm will come to Cherry plum if the temperature is consistently too high versus too low.

If Cherry plum gets too hot, seed germination and photosynthesis efficiency is lessened due to hormone triggers caused by heat stress. The plant will show signs through wilting, leaf browning, and potentially death.

If Cherry plum gets too cold, plant functions such as nutrient uptake and photosynthesis will cease, resulting in the possible death of the plant. If a single freezing event occurs during the growing season, then a membrane phase transition might occur, which can cause a cease in plant functions and death of the plant.

Question 5

What tips and cautions should I keep in mind when it comes to temperature for Cherry plum?

Accepted Answer

Keeping the soil temperature consistent is one of the most important strategies to keeping Cherry plum healthy, which leads to successful budding, flowering, and new growth. Do this by consistently watering, adding mulch to bare soil, and planting in the shade.

Question 6

How can I keep Cherry plum warm without a heat pad?

Accepted Answer

Due to the cold tolerance of Cherry plum, heating pads will not be necessary if planted outside in the ground. If the plant is in an outdoor pot, then bring it inside a heated house and place it in a sunny window during the winter months.

Question 7

How can I provide Cherry plum with an adequate temperature condition?

Accepted Answer

To ensure adequate temperature conditions are present, plant Cherry plum in an area with partial shade. If possible, use afternoon shade to provide the best protection during the hottest part of the day. This will also result in lower temperatures in the soil due to increased moisture retention. If Cherry plum is planted indoors, then keep the container away from windows and out of direct sunlight during the summer months to prevent the soil temperature from spiking daily.

Question 8

Should I adjust the temperature for Cherry plum in different seasons?

Accepted Answer

Cherry plum is a mid-temperature plant that can easily tolerate the typical fluctuations of the seasons and remain a hardy species when planted in maintained landscapes areas, containers, or indoors. Therefore, adjusting the temperature during the different seasons is unnecessary for primary growth. If flowering is stunted or impeded, then allowing the plant to experience a season of winter freeze could help to revive flowering.

Question 9

Under what conditions should I stop adjusting the temperature for Cherry plum?

Accepted Answer

If it becomes too difficult to lower the temperature for an indoor plant during the summer, then plant it outside in the ground or in a container. Make sure to plant Cherry plum in a shaded location and water often to keep the soil moist.
