What Is Wrong With Wisteria

danil123 added on October 4, 2011 | Answered

Please tell me what is wrong with my wisteria or the way I care for it. The wisteria does not flower, has yellowish leaves, and does not spread. I live in a warm climate=CA. I planted 3 foot tall wisteria I bought at Home Depot, which had flowers. After I planted it, it grew somewhat. . . spreading its vines, but then it slowed down to almost complete stand still. The leaves appear dry and yellowish. I water it about once a week. It is exposed to full sun. It is still alive, but it has been struggling all spring and summer.

If this is the first year that it has been planted, then this is typical, as far as growth. Wisteria need about 3 years to settle into an area and grows slowly and then after that, you will need a machete to keep it in check. If it has not been 3 years, give it a little more time. You have to understand that nurseries that sell plants can keep plants in ideal and atypical conditions that force plants to bloom when they are not ready so that the stores will be better able to sell them.

The yellow leaves though are a problem. This can be caused by several things. The first is that it is not getting enough water. Again, if this is its first year, it will need quite a bit of water to get well established and you may want to increase water until you see it improve. Nutrients may also be an issue and a balanced fertilizer may also help. The plant may also have pests or fungus that are affecting it, so treating the plant with a pesticide and a fungicide as a precaution is recommend.
