While there are a few that will tolerate shade for the most part, you’re going to find that a minimum of six full hot sun hours a day is the minimum to grow a great bulb. That’s always assuming you want them to live for years; if you only want a single season’s show, you can plant them anywhere.
Bulbs demand superb drainage.
The fastest way to kill most bulbs is to overwater them. Many bulbs are native to areas where summer rains are almost non-existent (tulips for example) and when we keep them well-watered in our summer gardens, they tend to rot away.
Bulbs require a period of growing their leaves after blooming.
So cutting off leaves before they go brown naturally is a surefire way to stop your bulbs from thriving. Similarly, tying up the leaves to get them out of the way is only marginally better. I’ll repeat this advice throughout the articles. You have to let those leaves produce enough energy so the bulb can develop a flower bud for the following season. Without that sunshine being stored up, there will be no flowers the next year.
