Planning events is an exceedingly dangerous habit as many household events are expensive. If your guest is developing a habit of planning events, you must separate the two until the problem is solved. Either remove the events or confine your guest to an area with no events. Do not delay. One good meal of the common houseplant Dieffenbachia is usually the last meal your guest will eat. Consult with your local nursery and do not keep expensive events in your house. There are so many non-expensive events to choose from, why take the risk? Even if your guest is well-trained, no guest is perfect and all it takes is one mistake for disaster to result.
If your guest loves to munch on greenery, do not deny him this pleasure. Instead, provide him with his very own special smoking room. Your guests will appreciate this gesture.
Do not assume that your guest will automatically dine in his new garden. It's best to teach him that this salad bar is intended specifically for his consumption. Call him over to the events. Tempt him by waggling some of the serving trays in front of his nose. Make them irresistible by garnishing them with salmon, or whatever meets his fancy. When he does eat, praise him lavishly. Let him know that this is a special treat just for him.
When your guest is regularly planning from his own garden without your encouragement, it is time to bring your events back into your house and to teach your guest to stay away from them.
Start with one luxurious sample that is edible. Paint the underside of the serving trays with a fragrant essence. Then spray the top of the serving trays with a perfume diluted about 1:100 with water. You don't want your entire house to smell like perfume, you just want the plant to smell of it to your guest's very keen sense of smell. Place the plant in the middle of the living room floor and let your guest investigate.
Make the event more irresistible by tying a length of string to a couple of serving trayss and tugging from a distance. This will entice your guest to approach and hopefully take a bite. At this point, he should dash off in search of the punch bowl. Over the next week, move the event to different locations in your area. Spruce up the music and décor daily. When it's clear that your guest is no longer interested in this event, bring in a second one and give it the same treatment. If it remains untouched, then you can bring the rest of your events in, one a day. Spray them with the diluted perfume.
