California’s 2013 was the driest year on record in 119 years.
Drought won’t stop us from growing tomatoes, but we do need to adjust some of our veggie variety plant choices.
Herbs by nature are naturally drought tolerant since most of them are Mediterranean.
Veggies are generally not naturally drought tolerant. Most are seasonally advantageous short rooted annuals, not deep rooted perennials. They grow quickly, need water to do that. Period. To produce fruitfully, they need to be able to make generous leaves to support photosynthesis to produce generous fruits and lots of them. Yet there are more heat loving varieties that do thrive in dry areas.
Some of us very coastal gardeners will be quite happy for the heat! It will mean we can grow plants we couldn’t before, like melons, pumpkins, large fruited eggplants, okra, that gardeners further inland, in the hot foothills, or south of us have been enjoying all along! There are even drought tolerant varieties of melons like Blacktail Mountain.
One drought solution is to grow only super prolific plants for the most return per square foot, especially the drought and heat tolerant varieties! These 5 are a great backbone-of-your-garden veggies!
- Indeterminate tomatoes produce all summer long from one plant! No need to replant determinates costing periods of time with no production and additional water usage. Of the heirlooms, Pineapple, per Bountiful Gardens is the most cold-hardy and drought resistant large tomato they have seen.
- Pole beans! Same issue with bush beans as with determinate toms. No need to replant bush beans costing periods of time with no production and additional water usage. Pole beans produce all summer long. Try Rattlesnake bean, aka Preacher Bean. 100-degree heat doesn’t stop them from producing lots of beans.
- Zucchini Dark Star, produces in only 50 days. It is the result of organic growers working together to grow an open-pollinated heirloom-type zucchini that could outdo the modern hybrids. The result is a zucchini with great performance in cooler soils and marginal conditions, along with a big root system that goes deep to find water and resist drought.
- Giant Fordhook chard, BountifulGardens.org says it is tolerant of drought and heat in our research garden.
- Kale! Curly leaf is super productive per its footprint! In our warmer weather Curly leaf kale, a favorite, is more susceptible to aphids, and those little devils are hard to get out of those convoluted leaves. One thing you can do is pick more frequently to keep new growth coming fast. And it will be a must to do frequent routine pest checks; keep flushing them away.But how about a heat tolerant flat leaf kale like Thousand Headed Kale?! It has multiple growth points instead of just one, so it puts out a lot more foliage and tender shoots. Huge plants make lots of food. A must for self-sufficiency.
Another super Brassica is perennial Tree Collards! From Africa to Los Angeles, TCs grow 6′ tall average, but up to 11 feet, live 4 to 5 years in continuous production! No lost harvest time because of needing to be replanted. TCs are high in Calcium, and unlike spinach, chard, and beet greens, collard greens don’t contain high amounts of oxalic acid, an anti-nutrient that can deplete your body of important minerals like Iron.
Check out Bountiful Gardens! They specialize in heirloom, untreated, open pollinated varieties for sustainable agriculture. In the drought tolerant section they say, ‘Please note that this does not mean that the crops listed don’t need some watering – these are crops that will grow with less water and all of these crops will need moisture to get established.’
Try new plants from arid countries. Maria Arroyo at our Santa Barbara Community Gardens office recommends a traditional local plant, zapatas, Prickly Pear! Both pads and the fruits are edible! The fruits, tunas, are used in brilliantly colored healthy anti inflammatory juices, uh, margaritas, a jelly candy, and jams. The pads, nopales, are used various ways. From Phoenix Arizona, here is Kymm Wills’ easy Nopales Recipe! When & how to harvest those dangerous nopales! Or, check out your local Mexican market.
I have been thinking of the Santa Barbara Mission traditional La Huerta corn. The cobs are quite small. That is likely what happens generation after generation when there is little water. Bet the New Mexico/desert varieties have small production as well. In some instances we will need to adjust our expectations about how much yield to expect when we use less water. We may need more land to plant more for the same previous yield.
This is time to check out southern university sites in states like Texas, New Mexico, Arizona, maybe Florida, hot states, for their successful heat loving varieties. Please report in to me your location and ones you try that prove successful. Please save those seeds!
Our planting techniques need rethinking. One simple garden practice to change is to plant IN furrows and basins/wells, like Zuni waffle gardens, would keep water right and only where it is needed rather than randomly watering an entire area. A more refined furrow technique is to make a deep furrow, flatten the top, about 8 to 10″ wide, and make a mini furrow there on top! With gentle and careful hand watering, your water stays right at the top where seedling roots need it, rather than running off and eroding the sides of the furrow, lost to evaporation. The bottom of your furrow stays dry and you footwear doesn’t get muddy! Later on, as plants get bigger, roots go deeper, you can water in the main furrows.
Soil amended with compost, worm castings or Sphagnum peat moss has greater water holding capacity.
- Santa Barbara County is #12 in California agriculture production.
- Broccoli is our #2 crop (strawberries #1), 20% of US production! Most of what is exported goes to Japan, cut in special forms to their taste!
- Farm production is up to 3B/yr.
- We could be in a 500 year drought. Farming as we know it will be changing. Wells are drying up.
- Nutrition is the base cause of noncommunicable diseases, 50+% overweight, 8% diabetes, our life expectancy now declining.
- Amazingly, we import 95% of our fruits and vegetables. Yes, you read that right. Suggestions – increase local food distribution, grow more at home!
- Mexico has the highest obesity rate in the world.
- Europe now has a 50% reduction of meat and dairy use.
- The Santa Ynez Valley Fruit and Vegetable Rescue gleans a 2nd harvest of unused produce, ie misshapen, too small, from farms, farmers’ markets, for seniors, youth, and others in need. Wonderful story!
Which Landscape Plants to Save? TREES!
Trees are long term plants, and they make shade. Shade means cooler, less evaporation, and though trees use water, they also preserve water.
I like Joan S Bolton’s thorough and thoughtful, informative professional post. HOW TO KEEP YOUR TREES HEALTHY DURING THE DROUGHT
Here are some more details at SB County Agriculture & Weights & Measures Newlsetter. See Page 4, Our Oaks are Thirsty by Heather Scheck.
Stay strong in these challenging times. Enjoy the changes. To your good health and happiness!
The Green Bean Connection started as correspondence for the Santa Barbara CA USA, Pilgrim Terrace Community Garden. All three of Santa Barbara city community gardens are very coastal. During late spring/summer we are in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is. Bless you for being such a wonderful Earth Steward!
