Shamrock luck!

Shamrocks  are for  good luck and are a popular house plant, especially during St. Patrick’s Day. 

Shamrocks are easy to grow if you follow these five simple and easy to remember steps:
·       Shamrocks prefer direct sunlight, be sure to place your plant in a window where it will receive plenty of light. Shamrocks will flower, even during winter, if they receive enough light. Each night the plant's leaflets fold up , then reopen in sunlight the following day.
·       Shamrocks like food! Fertilize them regularly with either a liquid houseplant or time release fertilizer during their growing season- always following label instructions.
·     As a houseplant, they prefer moist soil. Avoid allowing your shamrock to dry out during the growing season.
·       Give your shamrock a growing temperature between 50 and 70 °during the growing season. They can be placed outside after danger of frost has passed and are a beautiful addition to your pots or in a grouping of pots.
·       Shamrocks have a dormant period. When your shamrock
 goes dormant, usually in late summer, don’t fret! Just place 
it in a cool, dry location out of direct sunlight for 2-3 months. The purple-leaf types only need one month of dormancy!

Since your shamrock grows from small bulbs, it's easy to divide and create new plants. 

Here's a short video with how-to steps for propagating
Happy St. Paddy's Day to you!

Tomato Types

 What is Determinate or Indeterminate tomato seeds?

Determinate tomatoes are varieties that grow to a fixed mature size and ripen all their fruit in a short

period, usually about 2 weeks. Once this first flush of fruit has ripened, the plant will begin to diminish in vigor and will set little to no new fruit. 

Indeterminate tomato varieties are vining plants that continue growing in length throughout the growing season, which is why you will sometimes see them referred to as "vining" tomatoes, Indeterminate tomato varieties will also continue to set and ripen fruit throughout the growing season, until the plants are killed off by frost.  

Both determinate and indeterminate tomato varieties have their pluses and minuses. It really depends on what you are going to be using the tomatoes for and also, how long is your growing season. If you want a thick tomato for making sauces, you are better off with a paste tomato and those tend to be determinate.

If you tend to eat your tomatoes fresh and want a season-long supply, go for indeterminate varieties.

An heirloom tomato (also called heritage tomato) is an open-pollinated (non-hybrid) heirloom cultivar


of tomato. Any tomato that is at least fifty years old and is not a hybrid. According to tomato experts, heirloom tomatoes can be classified into four categories: (image Black Brandywine)

  • family heirlooms,
  • commercial heirlooms,
  • mystery heirlooms, and 
  • created heirlooms.  
They usually have a shorter shelf life and less disease resistance than hybrids bred to resist against specific diseases. They are grown for a variety of reasons, such as for food, historical interest, access to wider varieties, and by people who wish to save seeds from year to year, as well as for their taste.

When the plants of an open-pollinated variety self-pollinate, or pollinated by another representative of the same variety, the resulting seeds will produce plants roughly identical to their parents.

 Hybrid tomato – A tomato bred by crossing varieties. Hybrids offer better disease resistance, higher

yield, and other improved traits.

Early variety – A tomato that matures in 50 to 60 days; these are prized for early harvests and late summer planting for a fall crop. Sometimes we refer to tomatoes that mature in more than 60 days as “early,” but only in comparison to their peers. For example, the earliest beefsteak type is only early compared to other beefsteaks. Beefsteaks are typically longer maturing than other tomato types because they are so big! 

Tomato Disease Resistance Codes 
Tomato names are often followed by capital letters that stand for resistance to certain diseases. This is very important because these diseases can wipe out a tomato crop.

Xeriscape not ZEROscape

Drought tolerant landscape doesn’t have to mean gravel, and spiky gray plants. Xeriscape (xeri=Greek for dry and scape=view) emphasizes the use of drought tolerant plant species combined with creative landscaping practices to conserve water.

The following terms: water-wise, drought tolerant, water thrifty, and water smart all refer to plants requiring less water in a managed landscape. We all want to use less water in our landscapes and don’t want to be that house with the ugly brown yard.

Whether you have established landscape or total do-over, take a look at the following Eight Principles of Xeriscape:

1. Plant and Design comprehensively from the beginning.

  • Lower your water bill.
  • Create a more interesting landscape. Plan your annual flower and vegetable gardens and create a planting guide.
  • Invite more pollinators into your landscape.
  • Don’t just plant and hope for the best
  • Create a landscape plan. Identify all the plants in your landscape, their water, sun, and soil needs, and the seasonal maintenance for those plants.
  • Record the micro climates in your landscape. Record the plants you add and take out of your landscape and why. Record monthly and annual tasks to remind you when to perform them.
  • Develop a fertilization and mulch plan.

2. Create practical turf area. Consider size, shape, and appropriate grasses. Turf uses the highest percentage of water. When planning, consider regionally appropriate turf. Sheep’s fescue (Festuca ovina), and Buffalograss (Bouteloua dactyloides) are two examples of grasses that require less water and grow well in the Treasure Valley. Raise mowing height to 2-4 inches on your mower. The taller grass shades the ground so slows evaporation and promotes deeper root growth. Research shows mulching the clippings instead of removing them, can replace one application of fertilizer per year.

You might consider replacing some of the grass with a  more planting beds for flowers or vegetables. Don’t forget to check your HOA rules when considering the removal of turf.

3. Choose plants for your growing zone.
Once established, regionally appropriate native and low water use plants require little water beyond the normal rainfall (about 12 inches per year of precipitation in the Treasure Valley with 5 of those inches between April-October. Consider soil type, exposure to sun, and choose the right plant for those conditions. 

4. Consider improving the soil with organic matter.  Healthy soil retains water and absorbs excess nutrients, Have your soil tested for nutrient content, PH, soil composition and organic matter. The report will give you suggestions for adding anything that is lacking.

5. Strongly consider using organic mulches such as wood chips.  Adding mulch controls weed growth and slows evaporation, so conserves water. 

6.Irrigate efficiently. Create zones to provide the right amount of water at the right time by grouping plants according to their water needs. Your tree, shrubs, flower and raised beds have different water requirements than your lawn. Consider drip irrigation or soaker hoses for flower beds, shrub and trees. More targeted watering cuts down on weeds and uses less water.
Avoid sprinklers that produce a fine mist or spray high into the air in order to reduce water loss from evaporation and wind.  To check your sprinkler output, use tuna cans or similar straight-sided cans placed at various places around your lawn.  Run lawn sprinklers for 5 minutes and measure the output.  Now calculate the time needed to get  1 inch of water per week on your turf.
Water requirements change often so don’t just set automatic systems and forget them. Review the water requirements often taking into account rainfall, temperature and wind. Adjust the time you water accordingly.

7. Water Harvesting. Direct your roof water into rain barrels or onto your landscape. This recharges Idaho's aquifers as well as irrigating our arid environment. Here's how to build a rain barrel.

8. Maintain your established landscape.  Learn how to prune and fertilize each plant in your landscape and record the requirements in your maintenance schedule.

.Consider visiting xeric demonstration gardens in the Treasure Valley area. Hopefully they will inspire you to improve water conservation in your own home landscape.

The Idaho Botanical Garden has several gardens within its footprint, including The Water Wise Garden and The Fire Wise Garden.

 
These following two links will give you an extensive overview of xeric gardening.

How are your overwintering bulbs: Dahlias, Cannas, Gladiolas, and more...?

Dahlia
If you are trying to overwinter bulbs (includes tubers, corms, and rhizomes) such as Dahlias, Tuberose, Amaryllis, Canna Lilies, Gladiolas - now is a great time to check them to see what condition they are in. Here are the main things to check:

#1 Check for Disease If bulbs are damaged in digging and not "cured" well while preparing them for storage, you can get a soft rot in them and it will spread from bulb to bulb, or tuber to tuber very fast. A fast way to check for this is to use your nose, the rot will give off a rather bad smell, once you detect the smell, then use your eyes to look for discolored material or material that is oozing and looks moist.
Remove all bulbs that show the discolored symptom or are soft, you should also check with a master gardener to see is there is a fungicide that you can treat the ones not affected to protect them.

 #2 If you have put the bulbs in an organic bedding material, check it for moisture content - if it is damp that could increase problems with soft rot.

#3 Check the bulbs to see if they are wrinkling up which shows that they are drying out. Outside air can become very dry when it warms up causing a severe problem in over wintering your live material. 

Tubers such as dahlias are very prone to not surviving the winter unless they are in bedding material. If the bedding material is too dry,  it can allow the bulbs to dry out and die, of course if it is too damp then soft rot can be a problem.

#4 Check the temperature of the area you are storing them in. It should be less than 50 degrees F. and more than 40 degrees. It is very important that the bulbs do not freeze and if it gets too warm the bulb will start to grow and that can kill it.
