The hot, wet summer has been particularly good for growing melons. Cantaloups, honeydews and watermelons all seem to be enjoying the heat and humidity, more than I am.

Once the melon fruits form and start to grow big, the question always comes up about when to harvest the fruits. So, let's talk about harvesting melons.

The easiest melons to know when to harvest are the muskmelons or cantaloups. These are the netted melons. When the skin netting turns brown and the fruit easily slips off the vine when gently lifted, you can harvest. They also will have a sweet smell. Cantaloups are unique in that you can harvest a little earlier than when fully ripe and they will continue to ripen indoors.

Honeydew melons tend to have a smooth skin. There are many types of honeydews, but most do not continue to ripen after harvest. So, you need to wait until the fruits are fully mature to pick. Signs of a mature honeydew melon include a sweet smell and a change in skin color.

Watermelons are another melon that doesn't continue to ripen after harvest and it can be hard to know when they're fully ripe. The old folklore method is to thump the fruit with your thumb and listen for a hollow sound. That technique takes practice. A more reliable method is to look at the tendril or curlycue closest to the watermelon fruit. When it has dried up, check the watermelon belly. If it's turning a yellowish color, it's time to pick.

After harvest, store melons in the crisper drawer in your refrigerator if you won't be eating them soon.

Late summer is often a time with little color from shrubs in our yard. That's why I love Rose of Sharon.

Rose of Sharon's name is misleading. It's neither from Sharon, Israel or a rose. It's in the mallow family haling from Asia and is the National Flower of Korea. It came to Europe in the 1600's and North America during the colonial era. Thomas Jefferson particularly loved this shrub. This deciduous, hibiscus-family shrub has beautiful, white, pink, red, lavender, blue or bi-colored flowers that bloom now until fall. The flowers are edible and used in making foods and tea.

These shrubs grow 7- to 12- feet tall and make a statement with tons of colorful blooms. The 'Chiffon' series features white, pink, blue, lavender, or red flowers. The ' Pillar' series grows 10 feet tall, but only 4 feet wide, making it a good choice for narrow, side yards. There are dwarf varieties, such as 'Lil Kim' , which grow only 3- to 4- feet tall, and 'Sugar Tip', which is also short with variegated foliage.

Rose of Sharon flowers best in full sun, but can take some afternoon shade. Grow plants in well-drained, fertile soil. Prune in late winter to keep the shrub short and remove errant branches. Rose of Sharon flowers off the new branches formed in spring. Some selections are grafted with a different variety as the rootstock. If your Rose of Sharon magically turns a different color one year, it may be the rootstock is growing and flowering. Rose of Sharon is drought tolerant and deer proof, but remove self sown seedlings in spring.

There are few animal pests as clever as the raccoon. With their dextrose hands and feet, they can get into garbage cans, sealed compost bins and gardens with relative ease.

I avoided growing sweet corn for years because of raccoons. Then I thought I'd try popcorn. I figured popcorn doesn't have sweet kernels so the raccoons would leave it alone. That worked for a few years, then they found my patch. As usual, the night before I was ready to harvest they struck, munching only bits out of multiple ears and pulling down the stalks. I've seen similar raids on melons, beans and tree fruits!

So, what to do about raccoons. First of all, don't leave any standing water in your yard such as birdbaths and kiddie swimming pools. Raccoons love to clean their food before eating it.

Most fencing is not going to stop a nimble raccoon. They can scale even a tall wire fence. They can even use their hands to open up chicken wire fences cobbled together around a garden. The best fencing is wire cages with tops that completely cover the planting. Stake the cage down well. Of course, that won't work for my 6 foot tall corn stalks.

So, this year I bought a portable, solar, electric fence kit. By setting it up early around the corn patch, I hope to train the raccoons to stay out. It has a solar panel that charges the wires during the day and a battery to keep it charged at night. I just have to keep weeds and grass from touching the fence. Wish me luck!

One type of perennial flower that I really love is shrub-like perennials. These are plants that quickly grow large in one season and even when they aren't flowering, put on quite a show. The one that's blooming right now is hardy hibiscus.

Hardy hibiscus grows in zones 4 to 9 and is different from the woody, tropical, shrub hibiscus. The hardy hibiscus is a perennial, but dies back to the ground each winter. That doesn't stop it from being a showpiece! The 8-inch diameter, colorful flowers appear on shrubs that can grow 3- to 6- feet tall. The colors range from pure white to deep red in the 'Luna' series. This series only grows 2- to 3- feet tall. There are varieties with burgundy colored leaves as well such as 'Midnight Marvel' and 'Evening Rose'. There are bi-colored varieties, such as the pink and red 'Perfect Storm', and even a light yellow colored variety called 'French Vanilla'.

For best flowering, plant in full sun on well-drained, moist soil. Add compost in spring once the plants emerge and keep plants well weeded. The plants die back to the ground in fall, but leave the stems into winter as beneficial insects sometimes overwinter in them. Cut back the stems in spring and be patient. The new shoots are often slow to emerge from the ground.

Hardy hibiscus has few pests, but the hibiscus sawfly can defoliate leaves in late spring. Check for these small caterpillars on the underside of the leaves and handpick them or spray with an organic product such as Spinosad, in the evening when bees aren't active.

If you’re lucky, around mid-July, warm weather loving veggies are thriving. I recently returned from a trip to find our okra had grown a few feet while I was away.

Okra is a traditional Southern vegetable that should be grown in Northern gardens, too. Plant dwarf, quick maturing varieties now and harvest in 2 months. Dwarf varieties, such as 'Jambalaya' and 'Baby Bubba', only grow 3- to 4-feet tall and produce okra pods quickly in the summer heat. Try planting okra where lettuce or peas have gone by in your garden. The dwarf varieties are also great to grow in containers, too.

Okra is a vegetable that some people love and others hate. The pods have the best taste and texture harvested when they're less than 4 inches long. Young okra pods are more tender and have less of a “slimy” nature. Eat them in soups, stews, fried or sautéed. Okra is in the hibiscus family, so the flowers are edible and delicious stuffed, fried or used as a garnish.

Plant okra in full sun in the hottest spot of your yard on compost amended soil. Like the song by the duo Hot Tamale sings, “the okra don't grow if the water don't flow,” so keep the soil moist.

When harvesting, wear gloves and a long sleeve shirt as some gardeners can get a skin rash from the okra leaves. The pods are attached strongly to the woody stems so use a hand pruner to harvest them. Harvest every few days as the pods grow fast and furious in the heat. The more you harvest, the more pods you get.

With our warming climate comes many challenges. But one advantage is the possibility of growing some plants that normally would not thrive in Connecticut. This is true of crepe myrtle. Known as the “lilac of the South,” crepe myrtle has traditionally been successfully grown in zone 7 and warmer climates. But now with new hybrid, sterile, varieties from the National Arboretum and warmer winters, we can grow crepe myrtles in zone 6, and even zone 5, which opens up the possibility in all of Connecticut.

Crepe myrtle varieties come as shrubs or small trees. Choose the right type for your yard to avoid drastic pruning. Some of the best shrub-like crepe myrtles include the 2 foot tall 'Chickasaw' with small purple colored flowers and the 6 foot tall 'Caddo' with bright pink flowers. For small trees, try varieties such as the 10 foot tall 'Tonto' with red flowers and 'Natchez' with pure white flowers on 20 foot tall trees.

Crepe myrtles flower best in full sun on well-drained soil. They bloom in midsummer on new spring growth. Prune in late winter to encourage more growth and flowering, reduce the plant size and improve the structure.

The midsummer flowers are a treat when few other large shrubs and trees are blooming. Also, the bark exfoliates creating an interesting tree for winter viewing.

Crepe myrtle are good city trees because they tolerate pollution. Crepe myrtle has few pest problems other than powdery mildew and fungal leaf diseases during our humid summers. If powdery mildew is an issue in your yard, try growing disease resistant varieties such as 'Caddo', 'Hopi' and 'Tonto'.

I'm always looking for the most recent techniques to help protect our plants from deer and other critters. Deer browsing our shrubs, vegetables, and flowers is a constant source of angst for home owners. Fencing deer out of your yard is often not practical for a suburban homeowner, so repellent sprays are really the next best option.

Recent research at the Connecticut Agricultural Research Station, reported by Connecticut Gardener magazine, highlights the best repellents. Essential oil based repellents, containing oils such as mint, thyme or pepper, often evaporate quickly. Odor based sprays, such as those containing rotten eggs or blood meal, are more effective, but eventually wash off plants after about 5 weeks. In their research, the best deer repellent sprays were fat based. Fat based sprays don't smell bad to humans, don't need reapplying after rains and gave plants months of protection.

Fat-based repellent sprays were discovered in Austria when farmers noticed that deer avoided plants that had raw sheep’s wool hanging on them. Raw sheep's wool has lanolin-based fats that repel deer. Lanolin is a byproduct of wool processing and is safe for people, wildlife and the environment. While their research showed three months of protection from lanolin-based sprays, these commercial products, such as Trico, are very expensive.

A less expensive home remedy alternative that proved as effective as lanolin-based sprays is milk fat. Mixing Half & Half with equal parts water in a sprayer worked as well as the lanolin sprays.

The warm, wet spring and now summery weather has encouraged our summer squash and zucchini to thrive. But we're not the only ones enjoying these plants. Squash bugs are here and laying eggs on the undersides of summer squash, winter squash, and melon plants. You may not see much damage yet from the squash bugs, but if allowed to thrive, your squash patch will be a mess come August.

Squash bugs are brown or grey colored with a shield shape on their back. They emerge in spring after overwintering under dead leaves, rocks, wood, and other garden debris and start laying copper colored eggs in organized clusters on the leaf undersides. The eggs hatch into miniature squash bug babies that continue to feed on leaves and flowers. The population usually explodes come August when it's too late to really control them.

So, let’s do a little prevention now. Companion planting seems to help. Research from Iowa State University showed that interplanting nasturtiums among your squash deterred egg laying. The nasturtiums emit a fragrance that masks the squash so the squash bugs can't find the squash plants. Grow the trialing type of nasturtiums to have a good mass of plants. You can also check the undersides of the leaves every other day for egg clusters and squish them. You can also cut them out with a scissors if squishing isn't your thing. Finding and squishing the adults is good also.

The organic spray, Spinosad, can be used to kill the adults and young. Spray when the squash aren't flowering and in the evening to prevent harm to pollinating insects.
