A Good Mum

Much smarter now than when I moved here, especially in the ways of plants, when I watered the sunny yellow potted Belgian mums I frittered away $5.99 on and chose from dozens, and the water ran right out through the bottom and the blooms drooped as if aphids had got at 'em, I said to myself, "They're root-bound, that's why."

So animated with color and life that they are great company, they attracted another friend, the green one whom you see here. The mums come indoors at night because squirrels will wantonly destroy anything they see that I treasure. I was, however, thrilled to correctly identify the problem, tickle and rip their tough strangled roots apart, and transplant to a slightly larger pot where the mums now thrive. I've always been a talented transplanter; even Demetrius, the genius gardener, agreed I had the knack. Maybe I should try heart and liver transplants. The blooms perked up, and from day one have brightened the whole scene. So glad I paid the $5.99. When September comes, one must do everything possible to stay an optimist.

Trees in Love

Two trees embracing and kissing on the Divine Property, and I never noticed them until now. Views from both sides.

Beautiful Horrible

A new low: People throwing spaghetti from their cars into the roadside trees, I thought. But this showy jellylike ornament on a cedar branch, common after heavy spring rains, is Cedar-Apple Rust, not a fungus but a gall that grows only in the presence of both red cedar trees and trees in the apple family (including the hawthorn tree, bearer of Missouri's state flower). The same spherical gall can flower brilliant pumpkin-orange like this repeatedly during the spring, when rainy days alternate with dry. In a sinister and monstrous way it's pretty but not good news for the tree, and it's contagious.

A website explains: "Spring rains cause horn-like structures, called telia, to extrude from galls. When these horns absorb water, they become jelly-like and swollen. Between rains they dry to dark brown threads. The telial horns are comprised of thousands of two-celled spores called teliospores. Swelling and drying of telial horns may occur 8-10 times during the season. Each time, the horns push out further and expose more teliospores until the supply is exhausted."

I suppose it's just trying to make a living like everybody else.

Tomato Growing: Six Tips for Success

1. Gardener or guest, don't ever caress, pluck, fondle, feel up, or otherwise play with a tomato plant's foliage so you can inhale its gorgeous tomato scent. That's how animals locate tomato plants: by scent. Hands off.
2. When staking, wash and dry the stakes first and then use twine, organic preferred. Don't tie it tightly and avoid twist-ties, rope, thread, cloth, clamps or rubber bands which can scar the stem or hold water and cause rot.

3. Spraying or dousing the plant with water encourages fungus and leaf yellowing. Water at the soil level, splashing as little as possible.

Big Boys, July 4th
4. Use freshly-cleaned scissors to clip away "suckers" (upstart leafy growths in the "Vs" of the tomato branches) and THEN use the scissors to clip yellowed leaves from around the bottom of the plant. Clip away only the leaves that are majority-yellow. Do this in the morning so that the scars (and resulting tomato scent) can heal by nightfall, when the raccoons and skunks prowl. Gather the cut foliage and dispose of it far away from the garden.

5. Every other day, water until the bed has standing water.

6. To rid the leaves of "tiny white winged bugs" (thrips), Method 1: Boil a pinch of tobacco in two cups of water  (it stinks) and when cooled, pour this in a circle around the affected plant. Boiling this mixture hard kills any tobacco mosaic virus the tobacco might be harboring. Method 2:  Blast the bugs off the leaves with a brief spray of water. Spray sidewise, not downward toward the soil. Once should do it. This is the only time you break Rule 3.

The tomato is ripe if it's evenly colored and releases easily from the plant. Resist the urge to leave it hanging hoping it'll be growin' a little redder or bigger; that's just asking a critter to come and get it.

That's Not Spit On That Plant

Looks like somebody spit on it, but at the center of the white foam seen in crevices of roadside plants like these is the "spittlebug," well-hidden although you can find him if you want to look through the spittle. But he's counting on you to pass by. What happens is that a spittlebug egg has overwintered in the host plant, has hatched and become a nymph which drains the plant of its sap. The nymphs create the camouflaging "spittle" foam and hide in it for up to seven weeks as they develop into spittlebug adults. Adults lay a new set of eggs so a new set of nymphs can come along next year, and that's God's truth and the way He made 'em.

Fall Webworms

Hated seeing two-foot-long webby bags full of little maggots, ugly as sin and getting bigger every day, hanging from the old hickory tree that shades the house. Two of their bags were within reach of the ground. Had an urge to burn them.

Tried matches. The web would not light. At last I hit on wrapping pages of newspaper around the webs and setting them on fire.

After that was done I finally looked up the fall webworm, Hyphantria cunea. They weaken all kinds of deciduous trees by skeletonizing the leaves. Turns out that burning the bags, after wrapping them in rags, is a time-honored way of getting rid of them. The bags that can't be reached from the ground can be torn open with a stick or rake so that birds may come and feed on the webworms.

Odd-Looking Balls


Odd looking pods about the size of golf balls found here and there on the ground. Never seen them before. Looked them up in tree books. No luck. Opened (pictured at right), these light hollow spheres contained marvelous white dry fluff, but no seeds. Turns out this was a home of the parasitic Oak Apple Gall Wasp, Biorhiza pallida. And a fine comfily upholstered home it is. The wasp who dwelt in its center was long gone, to lay her eggs at the base of the oak tree and further parasitize it. These "pods," or more precisely "galls," may grow on either oak twigs or leaves. So if you see these they aren't spring fruits. Photos taken 11 May.

Oak Cherry Gall Wasp


Never saw this before, thought it was a fungus, but no; these are former homes of gall wasps who specialize in setting up housekeeping on the undersides of oak leaves. Taken yesterday. Latin name Cynips quercusfolii. Say that and you've said a mouthful.
