Frustration is Building....

My garden is stagnating. I've heard from gardeners all around town who are having the same problem. No rain plus weird inconsistent temperatures is stalling our veggies' growing patterns. Broccoli and other crops put in around September did their thing and are setting their second batch of crowns, but it seems that everything put in after that is just sitting. Waiting. Germinated then stalled. My garden is plagued with snails, which do their best to eat up all my germinated kale seeds and beet greens.


What is a gardener to do with weather doesn't do its part? Get frustrated, for one. And make due with what you have and what does work. And, add some fertilizer in hopes of making your plants happier. Seaweed is a great tonic to add to plants any time they need a little extra boost. You can buy powdered seaweed that you add to water and feed the soil and foliage for a little boost. If your crops are nice and green but lacking crowns or fruit, add a fertilizer with a large middle number. If your crops are just sitting there doing nothing, add some high nitrogen (first number) fertilizer. Side dressing with compost is always a good idea: make your own or purchase some from an organic nursery. No rain means you'll need to water a little more than you'd like, but cooler temperatures should keep the garden from drying out. Highs in the 70s aren't going to make your broccoli or cabbage any happier, so be sure and water on those mornings.



And at the very least, eat up what is available. This strange 'indian autumn' is at least providing more tomatoes and peppers, so have a nice hot bowl of chilly! Broccoli greens are edible, so even if you aren't getting the prize winning crowns you hoped for you can have a nice saute. And if you just can't stand watching your seedlings sitting there in a coma - head out to your local nursery and buy some lettuce and chard starts. They'll fill up the empty spaces, act as living mulch, and be edible in no time. Hopefully! You can also provide water and seeds for the local birds that will bring some welcomed color back to your desolate landscape.

Here in Austin we're lucky to have mild seasons great for growing veggies all year long. Sometimes the weather doesn't cooperate and things don't go as planned, but that's part of being a gardener: there's always a new challenge and something new to learn. At least the garden isn't covered with 3 feet of snow!

Garden Watch: Caterpillars On The Loose

The broccoli is growing crowns, the kale is leafing up fantastically, the chard is out of this world: but what's this? Little holes in those big, beautiful leaves?

One little caterpillar can do a whole lot of damage
Caterpillar Attack!
It is important to spend some time in your garden to observe the health of your plants and check for potential marauders. My garden is most often plagued with snails: they can at times be seen in vast herds on the walls of houses in my neighborhood and take advantage of rains to sneak attack the veggies trying to enjoy the drink as well. Nasty snails.  Along with snails are their covert friends: caterpillars. Small, green and camouflaged; large, fuzzy and obvious: all caterpillars want is to defoliate your lovely veggies and herbs as quickly as they can digest. Granted, some will turn to beautiful butterflies and should be left alone or even provided with specific habitat (ie dill plants for the swallowtail butterflies). This time of year though, most of the caterpillars in the garden should be hunted and squished - or fed to the chickens.
What to look out for:
  • Holes in leaves - may be small and round or jagged and 'chewed' looking
  • Broken stems or leaf stalks
  • Holes in tomatoes and other fruits
  • Strange grenade looking dung

Leaf damage like this can be caused by snails and caterpillars

The hornworms of Summer
If you see any of these signs, go in for a closer look: turn over the leaves of your plants and you may find an unwelcome visitor. Caterpillars will most often hide on the underside of the leaves and down in the center of a plant or flower. Tomato hornworms are remarkably well camouflaged and can sometimes only be spotted by the tell tale signs of leafless stalks amongst an otherwise healthy tomato plant, and the conspicuous grenade shaped dung they leave behind.
What to do with the critters once you've caught them? I generally squish the smaller, green caterpillars  or cutworms found on my brassicas and in the soil. The larger worms get tossed to the chickens to their delight - or thrown into the street for the mockingbirds to dispatch. It's not the most gentile job in the garden, but your plants will thank you for being their hero. They can't run away from threatening critters, and they'd much rather have your hands on them than nasty chemicals. However, If you have a bad infestation of caterpillars or a very large garden area you can supplement handpicking with BT (Bacillus thuringiensis) a natural soil bacteria that can fight off hoards of nasty caterpillars too vast to be handpicked. The great thing about BT is that it only targets the caterpillars and spares the beneficial insects.

Take some time to look over your plants today, it might just save their life - or at least maximize the bounty for you instead of for creepy crawlies. Also, please mind the lower temperatures during this lovely season. Temps below 40 may be too chilly for certain plants, especially tropicals and citrus. When our first freeze does show up in the forecast - pick what tomatoes and peppers are still on the vine and wrap any other sensitive plants with freeze cloth or old sheets.
