| The past few spring when I started my Amaryllis bulbs I found many of them had been bored into by (narcissus bulbfly?iris borer?). When I cut is open I find a dark brown mess in the center and a good sized grub. i assume this is because i put the amaryllis outside under a tree in the spring after blooming. What can I do this year to deter these pests, which are destroying my best bulbs? |
| How disappointing for you! There are two simple ways to protect the bulbs. One is to wrap each bulb in window screen to keep the grubs from entering and feasting, the other is to line the planting hole with rocks or sharp shards from broken sea shells. A one inch barrier of sharp stones or gravel all around the bulb will keep the grubs at bay. If you are so inclined you can treat the soil with Grubex or other grub control product. |
