>>775895Is that Salvia officinalis?
Better place it outside, it really needs a lot of light to not become leggy from my experience, this should also help with the insect problem
Plus, if only managable amounts of potting soil are concerned, you can simply sterilise it by putting it in an oven for a certain amount of time

>took a tiny cutting in late January from a friend's garden>put in water glass on my window sill>got roots by mid-February>planted in a pot and placed under grow light>planted out in the garden in mid-MarchSince then, it has grown into quite a remarkable shrub, considering it's been only 3 months.
I also have some seedlings, sprouted mid-February, that are placed in different parts in the garden since late March, but they're not quite as big yet. They grew leggy as fuck while inside even despite sitting directly on a SW window and having alu foil behind them for extra light, but once I planted them out they became bushier too
>>776108Well our "Blumenerde" we get to buy mostly contains still lots of uncomposted organic material, drains extremely well compared to our clay-like garden soil, and has a rather low pH of 5-6 (my garden soil is around 8-8.5)
