Stay cool. Make shade. Have a drink. Go to the beach. Harvest in the morning. Harvest in the evening.
It’s summer for all of us now — inland it’s felt like summer for a month already; but within a mile of the beach, it usually only starts feeling summery around the Fourth of July.
Take it easy in the yard this time of year. You should have planted and set up irrigation already, when it was cool. Your only job now is to reap and eat.
Make yourself a “Garden on a Pizza” pizza, like the one I made in the photo above. You can’t go wrong, just pick and chop and place. On that one I added basil, garlic, peppers, and tomatoes from my garden, plus nectarines that my mom brought me from her tree. Spicy and sweet.
While July is the zenith of summer harvest activity, it’s the nadir for planting. If you do plant — vegetables or fruit trees — the key is to thoroughly water the soil surrounding the planting hole. The moisture there from the winter rains is now all but dried up, and that dry soil will literally suck the water out of the hole where you put in a new plant. So, upon planting, water about six inches to either side of a new vegetable and two feet to either side of a new tree, and soak it so the water goes at least as deep as the plant’s roots. It’s vital. I’ve learned this lesson the hard way, having lost plants in July in years past because of not doing this.
In addition . . .
Sow and plant
– Sow or plant these vegetables any time in July (these produce before it cools down in the fall): basil, beans, corn
– Sow seeds of these vegetables, especially later in July, or wait until August (these produce after it cools down in the fall): brussels sprouts, cabbage, kohlrabi, broccoli, cauliflower, seed potatoes; it takes just under two months for these crops (not potatoes) to go from seed to a plant of good transplanting size
– Plant seedlings of these vegetables, preferably no later than mid-July: tomatoes (small-fruited types like cherry are safest, but see note below on “fall tomatoes”), tomatillo, pepper, squash (“summer” types like zucchini and yellow crookneck are sure bets for a fall harvest), sweet potato (slips); if you plant later than mid-July there’s a good chance you’ll get little harvestable fruit before it cools in the fall
– Plant “fall tomatoes” by mid-July; I find that early planted tomatoes (March) tend to become less productive toward the end of summer and into fall, so I’ve gotten into the habit of planting a few new ones in early July in order to ensure fresh tomatoes off the vine into fall; I usually don’t get maximum production out of these plants unless we have an Indian Summer, but they’ll likely produce better than your older ones that you planted in spring; I planted a handful of varieties on July 8 last year and got decent production from most, but the best were ‘Champion’ (photo above); an ideal site for fall tomatoes is one that will get low-angle, southern sun in the fall so the fruit ripens well at that time
Harvest and eat
– Eat these vegetables (had you planted them): tomatoes, tomatillos, potatoes, corn, greens, onion, garlic, lettuce, beets, carrots, peppers, eggplant, squash, basil, cucumber, melons, beans
– Eat these berries and fruits (had you planted them): blueberries, strawberries, grapes, avocados (Hass, Lamb, Reed), Valencia oranges, apricots, peaches, nectarines, plums, SpiceZee nectaplums
– Give deciduous fruit trees a pruning if you want to keep them down in size; this lets more light onto lower branches throughout the rest of summer, which encourages those lower branches to be fruitful next year; see this post about why I keep my deciduous fruit trees pruned to about eight feet tall; and see this post about how to do the summer pruning
– Protect avocados from sunburn; if a branch is exposed to hot summer sun it will burn and the branch will decline in health, so apply a sunscreen of diluted white latex paint (as I wrote about in this post)
– Water deeply just before a heat wave hits; this is particularly helpful for vegetables and avocado trees (see this post for more about watering through a heat wave)
– Stress not about powdery mildew on squash leaves, tomato foliage, melon, cucumber and pumpkin leaves because there’s nothing you can really do about it; there is no product you can buy that will eliminate it, and there is nothing you can do to your plants (such as changing your watering method or pruning out leaves) that will eliminate it; my experience with it in different gardens is that plants closer to the ocean suffer from it more often, plants in full sun suffer from it less often than plants in some shade, some years it’s worse than others, some varieties of certain plants (such as tomatoes) get it worse than others, and as some kinds of plants get old, such as squash, they almost always get it; see this webpage from the University of California for photos of powdery mildew and details about its growth and methods of control; the bottom line is: if powdery mildew wants to take down your vegetable plant, it will, so don’t waste your energy jumping through hoops to try to stop it — P.S. I’d be happy to hear if you have different experience with this
– Stress not about those squiggly tracks caused by leafminers on your citrus leaves; citrus trees usually flush new growth around this time and little insects called leafminers like this new growth, but fear not because they don’t do serious harm to a tree and they don’t do any harm to the fruit; the damage is basically cosmetic; see my post about leafminers on my lime tree a few years back
