Q.how to grow lavender inside
I was given lavender seeds and wanted to grow in pot inside if possible
Lavender is a Mediterranean plant that loves hot weather and sandy soil. I think you will find that it doesn't thrive indoors but you can try. First, it takes 2-3 weeks at 75F for seeds to germinate so be patient. If your home is cooler, germination will take longer. To regular potting mix add coarse sand or pebbles or additional perlite. The roots will rot in normal potting soil. Let the soil dry between waterings and provide supplemental light to stimulate bloom and growth. Fertilize at no more than half the rate recommended before it blooms and maybe 1/4 between end of blooming and winter dormancy. Do not fertilize over winter and decrease the amount of water it receives unless your house is very dry in winter.
