Waco Gardening Tips: SEPTEMBER

Herbs and veggies to plant this month.   

It's the last month to plant items in bold.  If a bolded item is grey that means the best two guides for this area, the Aggie Fall Direct Seeding Guide (AG) and the The Central Texas Community Gardening Guide (CTG) differ on whether this is the last month.

MORE PLANTING TIPS

• This is the month to transplant iris and calla lily.  There's a great video on how to divide and transplant iris here.  (But if they don't absolutely need dividing, possibly wait until next year.)
  
  
• Providing some shade for your plants may help with September heat.  Dorris at FlipFlopGardener suggests plant umbrellas (and gives some nifty instructions on how to set them up.   I've used plastic flowers to shade my read seedlings until they were strong enough to grow without shade, and it worked well.  

Some info from this page (but I'm not sure what...cause this is a post I re-did from a previous post) may have come from the Mother Earth News Website.

SOURCES 

Most of the info for this month's planting guide came from the Aggie Fall Direct Seeding Guides (which is now down from the site, but has been archived by the Way Back Machine), or The Central Texas Community Gardening Guide (CTG).   Some info also came from from the the 2023  Farmer's Almanac planting guide for Waco  which are marked with an*,  and the and  Month to Month Gardening in Texas, which are marked with ** (and has a note below).     I've been told the Farmer's Almanac is not as accurate as the Aggie Guide, but will include info from it only for veggies not listed in the Aggie Guide if I can find any evidence they grow in Central Texas (a mention on a gardening forum, whatever).  I will also use it for dates for planting indoors to transplant if it seems to be within a reasonable period from the Aggie transplanting guidance, since their guide doesn't cover this.

A few sources came from Central Texas gardening blogs or other sources, which I linked to.

**Note that Month to Month Gardening in Texas is not as specific by region.  It says that the last date to plant onion, leeks, and shallots is Oct 1.   The Aggie says in our zone we have til November 1.  The Central Texas Community Gardening Guide (CTG) says you can plant sets this month, and doesn't mention seeds.  I've planted onions and chives, both seeds and onion sets, all through the fall in Waco, and had them survive all through the winter, so I am not marking these as "last chance to plant."     


**** I have successfully planted dill in the fall, but I can't remember when I planted, so I'm going with the Farmer's Almanac "last planting date" here, even though it conflicts with their other planting dates.  The Aggie guide doesn't mention dill.

Waco Garden Calendar: April

 

What to plant in April:  

April is a BIG month for planting.   There is a LOT of things that can be planted this month, and not much left to plant in your veggie garden by May. 

I originally got this info from a book called Month-to-Month Gardening in Texas, but have now updated it with the Aggie Spring Planting Guide and the The Central Texas Community Gardening Guide (which are both more specific to this region).    A few of the pics no longer match but I'm a bit lazy to change it.  

This is the last month this Spring to plant the items in bold.  Those with "plant by" dates before the end of the month are noted.  The rest you have time to plant later if you want to.

*According to Aggie Guide

**According to The Central Texas Community Gardening Guide

***The Central Texas Community Gardening Guide and Aggie Guide disagree.  See plant below for details:

• Cantaloupe: Cnt. TX Guide does not suggest direct planting these by seed in Spring, but the Aggie Guide says you can.
• Eggplant:  : Cnt. TX Guide does not suggest direct planting these by seed at any time, but the Aggie Guide says you can plant this month.
• Lettuce:   Cnt. TX Guide says you can plant leaf lettuce (not head) this month, but Aggie guide says lettuce should be planted by March 15 (but does not specify leaf or head)
• Watermelon: Cnt. TX Guide does not suggest direct planting these by seed in Spring, but the Aggie Guide says you can.

I found the photos for my mosaic on Flickr, and the photographers were nice enough to offer up for use through Creative Commons (click on the links to see the photos larger).  Yes, the Sountern Peas (ie cowpeas) in that picture are blighted (that was just a hard one to find, so I took what I could get.)

*Both Aggie Guide and Cnt. TX Guide suggests an earlier plant by date, so these are no longer listed to plant this month.  I think the original was from a book on gardening in Texas, so it had less specific dates on some of these. It's not worth editing the picture over. 

Waco Garden Calendar: March

Below you will find a list suggested plant dates for March!

Instructions on seed packets will often say "plant after danger of frost." Well, ok, when is that? And how cold does it have to get for that frost to kill my plants?

Well, I looked it up on the Farmers Almanac and The National Garden Association and found that temps below 36°F are considered a danger zone, because colder temps higher up can cause frost to fall on plants below.   29°F to 32°F is considered a light freeze and will kill tender plants. 25°F to 28°F considered a moderate freeze is "destructive to most vegetation", and temps of 24°F or colder is a hard freeze and is even more destructive.  Past March 15 risk of a light freeze is lower, but if you want to be extra safe, you can wait until it's less likely to fall under 36°F at March 27.  Regardless, check the weather and don't plant if the weather is expected dip under 36°F that week.

***The Central Texas Community Garden Manual says plant seeds indoors this month, and the other guides say wait until February or mid-March and plant directly.  I've put cilantro seeds out starting in January, so I think anytime in March you want to plant them is fine.  No need to wait.

Waco Garden Calendar: February

 

Here's what to plant in February!  

Some notes from the The Central Texas Community Garden Manual.

"The earlier you plant in February, the less insect and disease problems you’re likely to have. "

But, since our last frost date isn't until March, there's some risk to it too.   Definitely wait to plant until temps rise above freezing (except for indoor planting).

Waco Garden Calendar: January

 

January may not seem like a great time for gardening, but there's actually somethings you can plant outdoors now, and a lot you can get started indoors.  

Direct Seed Or Use Sets:

Carrots (Aggie guide says after Jan 15, Central Texas Manual says after Jan 1)
Cilantro**

Onion (sets only - after Jan 15)***

Peas, snap (before Jan 15)

Spinach


Plant Inside To Transplant Later:
(Bolded means last month to plant these inside to transplant this season.)

Bell Peppers 
Broccoli
Cabbage
Cauliflower
Celery (after Jan 11)
Eggplant (after Jan 15)
Kale
Leeks
Lettuce (Head, not Leaf)
Oregano (after Jan 11)
Pak Choi
Pepper (Hot or Sweet)
Rosemary (after Jan 11)
Swiss Chard 
Squash (after Jan 15)
Tomatoes (after Jan 25)

Zucchini (after Jan 15)




**None of the garden guides list Jan as a time you can plant Cilantro...but I've had it sprout in Jan before. And I've heard of people up north overwintering these in the snow, so it's not likely a frost would kill it.  Plus, getting this in early means you might actually get enough to use before it gets warm and bolts.  They can be tucked between items that are slower growers.

***The Central Texas Community Garden Manual says plant seeds indoors this month, and the other guides say wait until February and March and plant directly.  I've put out onion sets straight outside in January before and they did fine.
