Plant Parenting: Use Coir to Increase Humidity for Seeds

June 10, 2020

Maintaining proper moisture is key to successful germination and healthy seedlings. The growing media should always be damp to the touch, like a wrung-out sponge. Never let it dry out, but don't let it stay too soggy either.

One trick to maintaining even moisture as seeds germinate and keep the surface of the soil from drying out is to sprinkle a thin layer of a material such as coir or vermiculite on top of the soil. I prefer to use coir. These materials will hold additional moisture, which can help prevent your seeds from drying out before they germinate.

Coir is a lightweight material made from the byproduct of coconut husks. It absorbs and holds water, while aerating the soil. Coir typically comes in a compressed block that you soak in water to rehydrate. After it soaks up water, coir becomes light and fluffy.


Plant Parenting: Thinning Out Seedlings

June 10, 2020

Once your seeds have germinated, it is time to thin their numbers. This part can be tough—no one wants to kill the seedlings they just grew.

When too many seeds germinate too closely together, the seedlings can struggle. It is tempting to let them all continue to grow, but your seedlings will be better off if you cull the weakest ones. More than one seedling per cell causes too much shading and resource competition, resulting in weaker seedlings overall.

If multiple seeds germinate in the same cell, keep the strongest and snip off the extras.
PC: Leslie F. Halleck

After your seeds have sprouted, choose the strongest, stockiest seedling in each cell and snip the remaining seedlings at the base. Throw the excess seedlings on your salad or feed them to any critters that would appreciate some greens.


Plant Parenting: Herb Stem-Tip Cuttings

June 8, 2020

When it comes to plant cloning, you'll probably take more stem cuttings than any other type. Herbs are a fantastic place to start multiplying your outdoor garden this spring as they are easy and quick to root by stem-tip cuttings.

Above, I used small short snips to remove a 2-inch section that contains two or three nodes along the stem. Each of these herbs will typically root directly in water, if I choose not to root them in a growing media. Make sure to remove any leaves that will be below the water or soil line.

I used a porcelain sprouting plate to keep cuttings from falling into water.
PC: Leslie F. Halleck

Don't overcrowd your cuttings. While you must maintain humidity around the cuttings during rooting, they also need good air circulation. Rooting media should be kept moist, but not soggy.

Herb tip cuttings can also be rooted in a lightweight growing media. Dip cutting in rooting hormone before sticking them. And be patient: while most herbs root relatively quickly, you will find that different plants will require more time than others.


Plant Parenting: How to Know When to Transplant

June 8, 2020

Two common mistakes that new plant propagators make include transplanting young seedlings or clones before they've developed a large enough root system -- or waiting too long to transplant. If you’re not sure how to gauge when a young plant is ready for transplanting to a larger container, the root system will tell you.

These tomato seedling shave started developing their first set of true leaves. Time to check their root growth!
PC: Leslie F. Halleck

After gently removing two plugs from the growing tray, I can see that the tomato seedling on the left has rooted completely to the bottom of the cell and is ready for transplanting. The plug on the right belongs to a slower-growing dwarf variety; its root system hasn’t quite filled the entire plug and some soil has fallen away when I removed it.

PC: Leslie F. Halleck

If you transplant too soon, you risk failure,since the root system isn't big enough to handle the disruption or a bigger pot with more soil.

Waiting too long may stunt the plant & they may not recover.


Plant Parenting: Crops Vary in Days-to-Harvest

June 3, 2020

Are you wondering when to start seeding your spring & summer vegetables? For all crops, you have to take the days-to-harvest into consideration.

Days-to-harvest varies, depending on whether you direct seed or transplant your edible crops.
PC: Leslie F. Halleck

The number of days-to-harvest can vary significantly, depending on whether you direct seed a crop into the garden or first grow a transplant. If you direct seed your crop into the garden or the container in which it will grow indoors, the days-to-harvest number on the seed packet is calculated from the date of germination.

For tomatoes, days-to-harvest start once they are planted into the garden.
PC: Leslie F. Halleck

Tropical crops, such as eggplant, peppers, and tomatoes, are typically started early indoors as transplants, allowing for bigger plants in the outdoor garden once temperatures are appropriate. For these crops, the days-to-harvest is counted from the date they are transplanted into their final container or outdoor garden location.

This is why you see southern gardeners starting their tomato seeds seeds indoors in January.


Texas: Lawn & Garden Tax Holiday!

May 1, 2020

Lawn & Garden Tax Holi​day ​Memorial Day Weekend 2020

Saturday, May 23 - Monday, May 25, 2020

The Lawn & Garden Tax Holiday was created in 2016 to encourage responsible water use in Texas. Over Memorial Day Weekend, retailers can sell select water saving products without charging sales tax (includes all plants & more). Below is a list of the items that qualify for the sales tax exemption:

Picture WaterSense Products During Memorial Day Weekend, retailers do not need to charge sales tax on any product tax free that displays a WaterSense label or logo. These items can be bought for either personal or business purposes.

Water-Conserving Products

Consumers can also purchase certain water-conserving products tax free. Unlike WaterSense-labeled items, these items are only exempt when purchased for use at a residential property.

Items are tax free during the holiday that are used or planted for:

  • conserving or retaining groundwater;
  • recharging water tables; or
  • decreasing ambient air temperature, and so limiting water evaporation

Examples of items that qualify for the exemption include:

  • a soaker or drip-irrigation hose
  • a moisture control for a sprinkler or irrigation system
  • mulch
  • a rain barrel or an alternative rain and moisture collection system
  • a permeable ground cover surface that allows water to reach underground basins, aquifers or water collection points
  • all plants, trees and grasses
  • water-saving surfactants
  • soil and compost

Examples of items that do not qualify for the exemption include:

  • construction/building materials
  • awnings and other items used to create shade
  • air conditioners
  • ceiling fans
  • sprinklers

Plant a Container Victory Garden 2.0

April 16, 2020

This post is provided as an educational/inspirational service of the National Garden Bureau and their members. See original post here: https://ngb.org/2020/04/08/container-victory-garden/

Grow a Container Victory Garden? Yes, You Can!

James H. Burdett did not address container growing in The Victory Garden Manual, but times were different in 1943. Today, growing edibles in containers is probably one of the fastest emerging trends we are seeing. Plus, with vegetable breeders working on more compact varieties, your choices for what to grow in a confined space are countless.

Ten Tips for Growing a Container Victory Garden 2.0:

1. Don’t underestimate the size of container needed for growing some vegetables.

Bigger is almost always better, but with larger containers comes a need for more soil and thus weight becomes a consideration, especially if you plan to move your containers often. Drainage is very important in a container as is soil depth. Good guidelines for choosing containers are provided in this article. For some additional vegetable container guidelines, this article will help.

2. Just as with in-ground plantings, you need enough sunlight.

Containers need 6-8 hours of sun per day to produce, but unlike in-ground plantings, you can move containers around to get more sunlight. Consider using containers with wheels, or otherwise easily movable containers, so they can receive enough sunlight.


3. What about wind? Are you on a corner balcony of a tall high-rise?

Think about how the wind might impact fragile plants or even topple the containers. Consider clusters of containers. Not only is it aesthetically pleasing, with plants providing some needed humidity for their neighbors, but also some plants can protect other plants from wind.

4. Vining crops need trellises

not only for support but also to grow upwards, saving horizontal space which might be at a premium.


5. Soilless potting mixes are great for containers, providing good drainage with less weight (less chance of soil compaction).

The larger the container, the more potting mix you’ll need which means less frequent watering.

6. Consider drip irrigation or self-watering containers depending on your availability to water frequently enough.

Container gardens do require more frequent watering (sometimes multiple times each day if it’s hot and dry) than in-ground plantings.


7. Proper fertilization is more important for container plantings.

More frequent watering can wash out some of the nutrients a plant needs to produce vegetables.

8. As with in-ground plantings: Know your zone and know your last frost date…

without that knowledge, you are setting yourself up for disappointment.

9. Think combinations!

Why not plant basil with a tomato plant? Or put beans with carrots? Spinach and onions work well together too. Some vegetables are pretty enough to be front and center and act like ornamentals!

To make it even easier, many suppliers and garden centers have searchable options for varieties that grow well in containers. Here are a few:

    1. All-America Selections
    2. Johnny’s Selected Seeds
    3. Burpee
    4. GardenTrends/Harris Seeds
    5. Park Seed
    6. Territorial Seed
    7. True Leaf Market
    8. West Coast Seeds

10. And last, but not least, don’t forget to plant some flowers for pollinators!

Flowers that attract bees are good and necessary no matter how or where you plant your vegetable garden.

Note: Currently there is a very high interest in gardening. Please be aware that many online suppliers are experiencing extremely high demand. Thus, there may be shipping delays and inventory shortages. Please be understanding and supportive during these strange times of uncertainty.


SUCCULENTS: Little Prince of Oregon Plant Unboxing!

March 31, 2020

Unboxing: Succulents for Your Indoor Garden

If you know me, you know I'm a big fan of tiny plants and unusual succulents, and am always on the hunt for new plants to collect. With many of you sheltering in place right now and spending a lot of extra time with your gardens and houseplants, I thought now would be a great time to share one of my favorite online retailers of unique plants.

I recently received a box of amazing Petite Prince succulents (some in their Plant Poppers line) from Little Prince of Oregon Nursery and wanted to share some of the amazing tiny plants they sent me. I'm often asked which type of succulents can be grown indoors with lower light levels, so I in the video I thought I'd share some of the plants I received that are perfect for beginners or indoor gardeners without a lot of space, specifically species and varieties of Haworthia.

At the end of my video I list all of the species Little Prince included in my box, and below I've added photos and descriptions of the species they currently have available at their retail shop. There were a few species I received that they don't quite yet have available, so I'll include those on a future post once they are ready!


Available Plants Included in my Unboxing

Click on the images of each plant if you want to visit the Little Prince retail shop!

Haworthia angustifolia

Haworthia angustifolia is an easy-to-grow haworthia featuring adorable, narrow, lanceolate leaves in a dense clump. I love this species because it looks fairly different from many other Haworthia. Tiny and compact for tiny pots! Low to Medium light.

Alligator Plant, Haworthia tessellata

Haworthia tessellata is an interesting, star-like rosette of thick, rough, green succulent leaves with distinct veining that looks oddly like alligator skin.
