| Hi expert, I bought two very expensive Monrovia Snowmound Spirea and had them shipped to me from Oregon about a month ago. I transplanted them in 20 gallon pots each immediately in very good potting soil. They're growing like CRAZY, however I have no flowers, not one. I see millions of buds, but they don't become white. I checked out everything about these plants before I bought them: I'm in the right zone, they are in full to partial sun, they are able to drain well and they are growing well, as I said and I fertilize them with Miracle Grow. Additionally, they did have a few flowers when I recieved them. Where's my flowers now? I bought these because I saw the beautiful flowers in your pictures. The only thing I can think of is they can't handle full sun and maybe it's burning the tiny flowers before they bloom or they don't like my fertilizer? Can you help. Thank you!

| Spiraea are some of the toughest, easiest shrubs to grow. They perform well in full sun or light shade, tolerate poor soils and little water. You may be treating them too well - fertilizer that's high in nitrogen will produce lots of green growth, often at the expense of blooms. I'd hold off on the fertilizer for a while to encourage bloom. Bridal wreath spiraea such as yours should be pruned after normal bloom time (late spring or early summer). Wood that has bloomed (or attempted to bloom) should be cut to the ground. This will encourage new flowering wood and a few late-season blooms. The combination of pruning and a less-rich diet should get your plants back into bloom. Best wishes with your garden! |
