This can vary per perennial variety, but in general they prefer the same planting conditions.
Here are the general steps to follow when planting spring bulbs:
• Choose a planting location that receives adequate sunlight and partial shade, has well-draining soil, and is large enough to accommodate the number of bulbs you want to plant.
• Prepare the soil: clear any weeds, debris, or rocks from the planting area, and loosen the soil to a depth of at least 8 inches. Add compost or other organic matter if your soil is poor.
• Dig planting holes: use a trowel or bulb planter to dig holes that are two to three times deeper than the bulb's height. Space the holes according to the recommended distance for your particular bulb variety. Do not bury your bulbs!
• Plant the bulbs: place each bulb in the hole with the pointed end facing up. Cover with soil, firming gently to eliminate air pockets. Water the area thoroughly to settle the soil and initiate root growth.
• Mulch the planting area: apply a layer of mulch to help conserve moisture, regulate soil temperature, and suppress weeds. Pine needles, shredded leaves, or straw are all good choices.
• Mark the planting area: use a garden marker or label to mark the planting area, so you don't accidentally dig up or disturb the bulbs before they have a chance to sprout.
• Care for the bulbs: after planting, continue to water the bulbs regularly to keep the soil moist but not waterlogged. Avoid overwatering or allowing the soil to dry out completely. Fertilize every two to four weeks during the blooming season. As the bulbs emerge, provide support if necessary and remove any dead or damaged foliage as needed.
