Root Knot Nematodes

Root Knot Nematodes Root Knot Nematodes (Meloidogyne spp.) are parasitic microscopic worm-like animals that infest plant roots and interfere with the uptake of water and nutrients. Infected plants will appear stunted, they may wilt on hot days even though soil is moist, they may have chlorotic or light green leaves and usually have reduced yields.       The roots will have "knots" on them where the nematode has entered the plant, and the "knots" do not come off easily, as can be seen on this nematode infested potato.   [...]

Gummosis in Fruit Trees

After the Freeze 2021

Freeze Damage to Plants I am sure everyone is anxious to know what damage the extreme cold temperatures have done to our landscapes. Unfortunately, it is too early to tell in most cases. You will hear me repeat this, I am certain, but “time will tell”. I know it is difficult to have patience, but because there are so many factors that can influence how a plant might be affected, that is exactly what we will have to do. Try to get used to the “ugly landscape”, as we really [...]

Why Did My Plant Die?

One of the most common questions we get at the nursery is about plants dying. Each situation is unique, as the conditions each plant is grown in is unique. But what happens when you plant several plants and only one or two dies? To be more specific, “Why did one plant die and all the others that I planted at the same time and treated the same way are fine?” I hope to be able to guide you through the diagnostic process and give you some things to think about [...]

Fire Blight on Pear Trees

For the third year in a row, Bradford Pears have been blooming during a rain event! Why does that matter, you ask? Because a very bad guy, a bacterium called Erwinia amylovora, or Fire Blight, enters the plant through the flower via splashing water. The first symptom to appear, shortly after bloom, is a blossom blight. The flower will appear water-soaked, then turn black. The most obvious symptom of this disease is the shoot blight phase, in which the tip of the shoot turns brown or black and bend over [...]

Citrus Troubleshooting: Common Problems

Nutrient deficiency: Iron deficiency is common in areas with calcareous soils and alkaline water. The iron may be present in the soil, but it is in a form that is unavailable to the plant when grown in alkaline conditions. Deficiency occurs on young leaves, and the veins remain green while the rest of the leaf is yellow. This condition can cause dieback of limbs and small fruit. Iron deficiency is also associated with excessively wet soils or prolonged wet conditions, as this depletes the root system and uptake of nutrients [...]

Growing Blackberries in Central Texas

Most of the varieties with thorns were developed in Texas. ‘Brazos’ is an old, reliable and tough variety, developed at Texas A&M in [...]

Citrus Harvesting: Is It Ripe Yet?

Knowing when to harvest any citrus fruit involves the question of the degree of maturity. Because citrus pass from immature to mature to over- mature slowly while on the tree, the fruit can be harvested over a period of months with small changes in fruit quality. Fruit color is a poor indicator of ripeness. Many fruits have fully colored rinds a long time before they are “ripe”, and others are green when sugars are high enough to make the fruit sweet. Citrus does not increase in sweetness or ripen more [...]

Growing Blueberries in Central TX

Rabbiteye blueberries can be grown successfully in whiskey barrel sized pots in Central Texas. Because they require acid soils, use a quality potting soil mixed with 1/3 sphagnum peat moss. The pot should drain well, and no saucer should be placed under the pot to ensure thorough drainage. Blueberries require full sun to produce well. Use a fertilizer formulated for acid-loving plants, such as an Azalea/Camellia/Gardenia fertilizer. Do not apply any fertilizer the first year. Starting the second year, fertilizer in late winter to early spring. DO NOT use a [...]
