Tips for selecting healthy holiday plants

It’s poinsettia season and this Mexican native is everywhere, forced into December bloom. The poinsettias available today are better than the ones sold a generation ago – and it’s not just the wider range of colors.
“Breeders are also enhancing features that make the plants more enjoyable for everyone,” says Diane Blazek, executive director of National Garden Bureau. “They’re developing varieties that bloom earlier, have longer-lasting blooms, and unique bract shapes.”
The bracts – what most people think of as petals – now come curly, skinny or extra wide. No matter the bract shape, the key to selecting a fresh poinsettia that will last until New Year’s is focusing on what’s at that center of those bracts – the small yellow true flowers or cyathia. They should look fresh and not turning brown. Any poinsettias missing those little yellow flowers are past their prime.
The bracts should appear fresh, too, but also notice the dark green leaves lower on the stem. Make sure the foliage looks healthy and not drooping or falling off.
According to experts, the most common problem with poinsettias is overwatering. People kill them with kindness. Take off the foil wrapper or punch holes in the bottom (and place a saucer underneath). Poinsettias – semi-tropical members of the Euphorbia family – demand good drainage and prefer soil on the dry side of moist. Give the plant a drink once a week (or as needed) and don’t let the poinsettia stand in water. The best way to know if your poinsettia needs watering? Pick it up. If it seems light, it’s time to water.
Cold kills poinsettias; they can’t take prolonged temperatures under 50 degrees. So, if decorating with poinsettias outdoors, bring them inside or protect them at night. They prefer bright light and temperatures between 65 and 70 degrees (just like most people do).
Contrary to popular belief, poinsettias are not poisonous – to people, dogs or cats. Studies at Ohio State and Washington State universities debunked myths about poinsettia toxicity. A 50-pound child would need to eat more than 500 poinsettia bracts to reach a toxic level.
That doesn’t mean poinsettias are edible. Their milky sap will cause mouth and skin irritation (and keep any person or animal from munching them).

Garden Checklist for week of Nov. 3
November still offers good weather for fall planting:
* If you haven't already, it's time to clean up the remains of summer. Pull faded annuals and vegetables. Prune dead or broken branches from trees.
* Now is the best time to plant most trees and shrubs. This gives them plenty of time for root development before spring growth. They also benefit from fall and winter rains.
* Set out cool-weather annuals such as pansies and snapdragons.
* Lettuce, cabbage and broccoli also can be planted now.
* Plant garlic and onions.
* Keep planting bulbs to spread out your spring bloom. Some possible suggestions: daffodils, crocuses, hyacinths, tulips, anemones and scillas.
* This is also a good time to seed wildflowers and plant such spring bloomers as sweet pea, sweet alyssum and bachelor buttons.
* Rake and compost leaves, but dispose of any diseased plant material. For example, if peach and nectarine trees showed signs of leaf curl this year, clean up under trees and dispose of those leaves instead of composting.
* Save dry stalks and seedpods from poppies and coneflowers for fall bouquets and holiday decorating.
* For holiday blooms indoors, plant paperwhite narcissus bulbs now. Fill a shallow bowl or dish with 2 inches of rocks or pebbles. Place bulbs in the dish with the root end nestled in the rocks. Add water until it just touches the bottom of the bulbs. Place the dish in a sunny window. Add water as needed.
* Give your azaleas, gardenias and camellias a boost with chelated iron.
* For larger blooms, pinch off some camellia buds.
* Prune non-flowering trees and shrubs while dormant.
* To help prevent leaf curl, apply a copper fungicide spray to peach and nectarine trees after they lose their leaves this month. Leaf curl, which shows up in the spring, is caused by a fungus that winters as spores on the limbs and around the tree in fallen leaves. Sprays are most effective now.
