It sounds as though your orchid is getting too much water. Epiphytic and lithophytic Vanda orchids are naturally very sensitive to over-watering, but the terrestrial species will also be hurt if you leave them with their feet wet. Always let the potting medium dry out thoroughly before you water your Vanda orchids.

The recommended day temperature for Vanda orchids is 75 - 85?? F. If you want to provide your plant with ideal orchid care, you should lower the temperature to 65-75?? F during the night to mimic the conditions found in the natural Vanda orchid habitat. Healthy and well established Vanda orchids can usually cope with occasional temperature extremes as long as they are brief.

An important aspect of Vanda orchid care is providing your plant with sufficient amounts of light. Vanda orchids need a lot of sun light, but should be protected from intense midday sun. Ideally place your plant in a spot where it can enjoy full morning and afternoon sun while being shaded from 11 am to 3 pm. Yellow leaves indicate overexposure to strong sunlight, while dark green leaves indicate that your orchid needs more sun. Strive to keep the leaves light green.

Suitable Vanda orchid care that includes sufficient amounts of feeding can make your orchid bloom more than once a year. Use a high nitrogen fertilizer (25-9-9) year round. For a normal strong fertilizer, one teaspoon a month will be enough. Ideally split up the dose and provide your orchid with several feedings instead of giving it all its food in one large serving.

By adjusting the growing conditions, I'm sure your Vanda will bloom for you. Enjoy!
