Hardy Trees, Shrubs and Vines

The roots of hardy plants grow during our cool months even though their leaves may be changing color or falling from their branches. This provides a better root system so they thrive in spring and can survive the long, hot summer. Live oaks, magnolia, cedar elm, hawthorns, holly, sage, junipers, roses, just to name a few, are winter hardy and would be appropriate to plant now. Read more: Plant Hardy Trees And Shrubs Now

Christmas cactus is one of nature’s gifts for those who are gardening challenged. Just keep them dry and in very filtered light. How’s that for easy?

A beautiful holiday plant, the Christmas Cactus blooms at Christmas and also sometimes around Easter if cared for properly. Keep the plant in a well lit location (like near a window) away from direct sunlight-too much heat and light can stunt the growth and burn the leaves. It should also be away from drafts, heat vents, or other sources of hot air. Feel the soil with your fingers; if it is dry, it’s time to water thoroughly. Before watering again, check to see that the top inch of soil has dried thoroughly first. Mist leaves as well as watering the soil. Read more: Christmas Cactus.

Fall bulbs like paper whites and amaryllis, will make a spectacular show this winter and spring, and now is the time to buy them.

Paperwhite Narcissus
1. Refrigerate for 4-6 weeks prior to planting.
(plant around Thanksgiving for holiday blooms!)
2. Fill a clear vase with a few inches of pea gravel.
3. Nestle bulbs side by side into the gravel.
4. Add water up to the bottom of the bulb and
place near a sunny window.

Amaryllis
Plant in a pot or in the ground. If planting in the ground, place in morning sun and afternoon shade. Every three years in October, you can dig up and divide these bulbs as they multiply underground! Feed regularly with Hi-Yield Bone Meal every 4-6 weeks.


Fertilize

BEDDING PLANTS
with Osmocote Time Release 14-14-14 or Miracle Gro. Organically with Hastagro, Medina Growin Green, Lady Bug John’s Recipe, or Milorganite.

Do not fertilize TROPICALS. They need to rest.

LAWN
If you didn’t fertilize your lawn in October or November, instead of applying a chemical fertilizer, we recommend you use an organic fertilizer such as Lady Bug Lawn & Garden, Medina Growin Green or Milorganite. These products feed the grass & soil microbes slowly and naturally.



Watch Out For

SCALE
insects on hardy trees and shrubs. Spray with Neem Oil spray or Dormant Oil.

LAWN FUNGUS
This can be a major problem after long periods of wet, cool weather or over watering. There are two major kinds of lawn fungus – Take All Patch and Brown Patch.

Treat Take All Patch with Fertilome Systemic Lawn Fungicide. Organically with Nature’s Blend Organic Compost, or Peat Moss. Treat Brown Patch Fungus with Bayer Lawn Fungus Granules, or Fertilome F-Stop Granules. Organically with Serenade.

Water

Only as needed – but dry cold fronts, high winds and low humidity can dry plants quickly.

Established lawns only need water every couple of weeks, provided we don’t get rain.

Be sure to check your sprinkler system and adjust accordingly.

Prune

  • Perennials that have finished their bloom.
  • Pick spent flowers from annuals to prolong their bloom season.
