COLD TOLERANCE OF SWEET BROOM HOW TO

This not so spring like look results from the plant’s inability to absorb potassium from the soil, due to cold. But moved outdoors from a warm greenhouse to a cold garden will cause the needles to color up orange and red.

I have had angelina survive the winter in a small pot I had forgotten to get in the ground. However the heuchera Creme Brulee seems to shrug off the cold. Lime leaved heucheras do not have much tolerance for cold. Forced pots of hyacinths need some limited exposure to the elements before they are placed in a spring container.

A hothouse grown perennial may react poorly to being put outside without a hardening off period. Other growers pot up bare root perennials in early spring, and bring them on in a warm greenhouse. Some growers winter their plants in tunnel houses with no heat, so they are subject to the same cold conditions as perennials already planted in the garden. The same would be true for spring flowering perennials. However, peas that that has been germinated or grown in a warm greenhouse will react poorly to a drastic change in environment. Pea seeds can be sown when the soil is workable, and the soil temperature is 45. Early vegetables that are sown directly in the garden do not experience transplant shock. A few hours a day in a shady place, then the day outdoors in the sun. Hardening off is a process of exposing seedlings to the reality of seasonal weather, a little bit at a time. Gardeners who start their own vegetables from seed indoors know that those seedlings need to be hardened off before placement in the garden. Placing them outdoors in cold April weather did not send them into shock. The pansies had had months to become accustomed to cooler conditions. This project was planted solely with plants that had been sown and grown to a good size last fall, prior to being wintered in a cold but not freezing house. That does not mean that they will not adapt and tolerate it.

How to best avoid cold damage in early spring is to be sure you are using plants that have had the opportunity to become accustomed to, or the inclination to tolerate the cold. We planted containers for a client in downtown Detroit Thursday and Friday of last week-a dicey move, considering the overnight temperatures were very cold. The overriding concern is always the cold. Planting containers for early spring has its pleasures and its pitfalls. At this moment, I am trying to stay focused on all thing spring. It can be heartbreaking, getting ahead of the weather. I would only suggest that your awesome early picks need to be, at the very least, housed in the garage until the night temperatures are reliably over 50 degrees. Every serious gardener wants to purchase the best from a big collection. If you do not have a glass house to protect annual topical plants from the late spring Michigan weather, focus on what the spring has to offer. The transition from a hot house to your garden can be a huge shock to those plants. A greenhouse crop of container plants is usually available for purchase way ahead of predictably warm weather outdoors. Those sunny days in April push those plants with tropical origins into very active growth. A greenhouse, on a sunny day in March, gets very warm, as in upwards of 80 degrees. Their place on a greenhouse bench is an ideal world. Everything regarding their culture is right as rain. The tropical annuals that are greenhouse grown for summer containers are living in a warm world right now. Containers planted with spring and cold tolerant plants deliver every bit of three months, and will happily accompany your spring garden coming on.

Refrain from planting these cold sensitive plants until the soil and the air temperatures warm up. Annual plants that are greenhouse grown for summer containers will not like our cold soil, or the cold air. My recommendation for containers this 17th of May in Michigan? Do not be thinking coleus, New Guinea impatiens, begonias, licorice in any of its forms, sweet potato vine, cannas – the list of summer container tropical that do not tolerate cold soil is long. Planting containers for spring is a great idea.
