My Trailing Begonias Have No Flower Buds

Question

I have 50 begonias which I stored over winter, they have lots of leaves but no flower buds. Can I have enriched the potting compost could this have caused this problem. can I reverse this.

Answer 1

If you have added too much nitrogen, then you can offset with potassium and phosphorus. If you have added enough nitrogen to start showing burned tips, then you will have to start with fresh soil.

This is almost always caused by too much nitrogen, and not enough phosphorus and potassium, with more emphasis on phosphorus.

Before fertilizing, make sure that your soil test confirms that you need to feed. Once it has confirmed what the soil lacks, if anything, then you can add just those nutrients.
