Early Weed Control In Satsuma’s

UGA Extension Agent in Lowndes County, Jake Price, has this update on weed control:

The warm weather we have been experiencing is unbelievable. Usually we can depend on Jan and Feb for some cold temperatures. With these temps trees may be waking up early which is not good especially if we have a late hard freeze. Time to apply the first application of fertilizer is approaching as well (late Feb to early March). Also if you plan to use a preemergent herbicide, it will be wise to put that out very soon. Attached is the fertility recommendation for satsumas from Auburn University and a fact sheet on herbicides and leaf miners.

If you have been using the same herbicides/pesticides over and over, it will be smart to rotate other materials that are not in the same class. There are a couple of miticides that will also have efficacy on citrus leaf miners, (Ari-Mek and Micromite). Citrus leaf miners have not been damaging our first flush of new foliage so wait until after bloom to apply any insecticides. This will also be a more “bee friendly time to apply your pesticides”. This is usually around the first of May.

Pre-Emergent Weed Control

These herbicides should be applied to a fairly clean soil surface prior to emergence of weeds. In Georgia/North Florida late winter is a good time for the first application. At least two applications are needed per year. Common practice in Florida groves is to not use pre-emergence herbicides on newly planted trees although several herbicide labels below allow for their use.


Post-Emergent Weed Control

These herbicides are either systemic or contact herbicides. Systemic herbicides are translocated throughout the plant while contact herbicides kill plant parts in which they touch. Drift from systemic herbicides will likely cause more damage to trees.


Mechanical Weed Control

The use of landscape fabrics around trees can help eliminate weeds. Also, the use of BH-10 (both hands, 10 fingers) can be used around trunks of small trees where cultivation or landscape fabrics are not applied. Cultivation or tillage can be used but at the risk of damaging fibrous root which can lead to invasion of pathogens or insects.

For more information, UF has a publication on 2015 Citrus Pest Management – Weeds.

Late Irrigation In Satsuma’s


We are learning a lot this season as we experience abnormally dry weather this fall. It’s normal to be dry in October, but going into October dry is not normal. Once daylight shortens and temperatures drop, these plants move into a cold acclimation period as they prepare for dormancy. The water demand is lower. With 80 degree temperatures and no rain through October, you feel like you gotta run irrigation to get plants through the fall. When should we cut it off?

Last winter was not good for the southern peach crop, but good for citrus production. The satsumas had a great winter last year, with only a few nights getting into the mid 20s. The trees looked much better this season. These trees are between 3 and 4 years old now. They are producing satsumas but the taste is not ready.

This week, we noticed lots of suckers growing from limbs. It being November, this is really the time when these trees need to be shutting down, sending more sugars to the roots to prepare for the winter. We believe our watering through October has kept these trees producing shoots. UGA Extension Pecan Specialist Dr. Lenny Wells reminds us not to run too much irrigation on young pecans trees as they need to go dormant.

When we looked at the soil around these satsumas, we found plenty of moisture. This was inside the row between the trees. It’s actually safe to turn off irrigation when moisture is present between the trees 6 inches down. These roots still have plenty of moisture.

Satsuma Grower’s Fall Update – October 5th

Sunburned Satsumas


Lowndes County Agent Jake Price coordinates our Satsuma production updates and manages a rootstock variety trial below Valdosta. He has come across some sunburned fruit I want to share.

Portions of the fruit, (blossom end mostly) are turning yellowish orange. This is from intense sunlight causing a burn on exposed fruit. This can cause the cells underneath the burn to dry up and reduce fruit quality. The fruit I have dissected do not seem to be dry underneath the burn at this time but that could change. There is really nothing that can be done about this. There has been some work done using kaolin clay to cover the fruit but it is washed away with rain so it doesn’t seem practical.
