How to regulate the flowering period of camellias? A detailed explanation of the latest methods

1. To make them bloom earlier, you should choose early-flowering camellia varieties. After they bloom in early spring, increase the temperature to accelerate the growth and filling out of new young shoots, and make growth stop earlier; around August, apply a 500-1000 times gibberellin solution to the flower buds that are forming, generally once every 3 days or so, until the flower buds show color, then stop.

If during hormone treatment the flower buds enlarge slowly, after September you can change to applying it once a day. When the flower buds gradually enlarge and the scales loosen, you can peel off 4-6 pieces and continue applying. During the flower-forcing process, you can apply 2-3 light fertilizer applications. In this way, camellias can bloom earlier, around October.

2. To delay the flowering period, you should choose late-flowering varieties, wrap the plant to protect it from cold, then move it to a low-temperature room at 2-3°C and give it about 6 hours of weak light treatment each day for about one month, and the flowering time can be delayed. The above is an introduction to the topic.
