One of the biggest challenges of growing in a small space is finding the room to grow flower bulbs. While perennial bulbs, like daffodils, will require more thought. I generally can plant tulips anywhere, because I treat them as an annual which will be removed after bloom. This fall, I’m planting roughly 1500 tulips in the backyard. It is for this reason, that trench planting tulips is such a helpful technique.Â
To begin trench planting, I’ll need to dig a trench. Obvious, right! I generally make the trench about twice as deep as the height of the bulb. If in doubt, you can always reference the planting depth on the bulb packet instructions. 
While several bulb packets suggest a large spacing, I like to pack the bulbs together closely (but not touching). I usually allow just under 1 inch between bulbs. Since tulips are true bulbs, the flower bloom size is already determined. 
Do you have any tips and tricks for easily planting tulip bulbs? If so, I’d love to hear all about it in the comments below. I hope you’re having a wonderful day!
I’m curious, why do you treat them like an annual? Do they not grow back each year?
Those bulbs look big and healthy.
