Are Gardenias Considered Acid-Loving Plants?
Yes, Gardenias are acid-loving plants. They do better in acidic soil than neutral or basic soil. They love soil that is full of nutrients, which means you need to add manure and peat moss to your soil to maximize the blooming potential of the flowers.
Gardenias will flourish in moderately low temperatures of between 65-70F during the day and 60-65F at night. Your gardenias will form flower buds only when you meet all these conditions.
Avoid planting gardenias near a foundation or a concrete wall. The alkalinity of the structure will affect the growth of your plant. Don’t use concrete vases for your gardenia plant.
Use diluted fertilizer for these low-pH plants every two to three weeks. Do this between March and October when it is the growing season. When it gets to November, cut them below the leaf node to encourage blooming.
When applying fertilizer, use either of two methods; mix it with the soil and then pour water on the plants. Alternatively, you can add the fertilizer to water and then apply the mixture to the soil.
Avoid splashing water on leaves and flowers if you go for the second method. Also, try to use less fertilizer than recommended. It helps to reduce the chances of burning the leaves and flowers.
