Southern Giant Curled Long Standing Mustard

Southern Giant Curled Long Standing Mustard is a vegetable we’ve test grown in recent months with great success in San Francisco, CA. If it can grow here, with our intermittent fog, it can probably grow for you. As with most vegetables, Southern Giant Curled Long Standing Mustard likes a lot of sun. It can tolerate up to a half day of shade. It is fairly pest and disease resistant. We believe this is due to the rough texture of the leaves, and of course the breeding. This vegetable can have leaves cut consistently and keep producing. Because this is a leafy vegetable, it can be grown for quite a bit of the year in most climates. As with most vegetables, it likes rich aerated soil, not to dry out for too long before next watering, and good air movement. When cooking this vegetable a few ideas are steaming it, cooking it in olive oil until it turns dark green, or including it in a dish. It seems to us to be most similar to Kale due to the texture and flavor of the leaves.

Angel’s Trumpet is quite the rewarding plant to grow. This vigorous plant (also can be trained to grow as a shrub or tree)  loves full sun, has fragrant flowers, and grows six to eight feet in height when mature. This plant can grow well in a pot or the ground. It does not like to dry out between waterings, and cannot get colder than 20 degrees Fahrenheit. Here is a beautiful white potted variety that can be transplanted into the ground, a pink one just like the one in our garden photo below you can grow from seed, an orange one that can be grown from seed, and a beautiful potted peach variety.

Sunflowers are quite an amazing annual. They can grow in sunny, somewhat foggy, and partial shade areas. They can be anywhere between 2-14 feet in height, with one to ten flowers on a plant. They grow fast, and many tolerate substandard soils. They are also fairly drought tolerant. Many are so tough, wind does not bother them. They can be used for a privacy screen between your house and that of a neighbor. To do this, we recommend not just one row, but 2-3.

We recommend planting sunflowers in pots or a clearly defined area first. That way, when they sprout, they can be replanted to exactly their final location.

After a sunflower is done blooming, we recommend cutting the head and drying it to keep the seeds. Another way to keep the seeds for later growing is to put a thin cloth around the head and twist tie it. Or, of course if you like you can let birds eat the seeds when it is done flowering.

Below is a photo taken today in our San Francisco California garden. These sunflowers are 3-7 feet in height. They would have grown taller, but we experimented here with letting them all grow in small pots until they were 1-2 feet tall, and then planted them out. This meant they were used to being confined so now will not grow as tall. That is a good way if you like to control the size of your sunflower plants. Click here to see our favorite sunflowers.

Marigolds can be one of the most fun and rewarding annual plants to grow from seed at home.  Marigolds exhibit beautiful, brilliant yellow, orange, or red blooms.  They have compact bushy growth and can bloom for weeks to months.  Although marigolds can be planted from seed directly in the garden, I prefer to plant seeds in a sterile medium inside it the house in a window, in the basement under lights, or in the garden in trays.  This way once plants are large enough, they can be transplanted into the garden.  Marigolds are terrific for container gardening, sunny borders, or filling in empty areas between other plants.  Marigolds do not tolerate frost well so should be planted in the spring after danger of frost.  Marigolds like full sun.  Seeds can be planted 1/4″ in depth.  I generally plant marigolds seeds very close together and then thin them to between 1 inch to 12 inches apart.  The amount that you thin them will depend on how dense you want your marigolds to grow.  The marigolds in the photo, Happy Days Red, are planted very close together for a more impressive show.  Most marigolds bloom at a height of 3 inches to 12 inches. The marigolds in this photo are about three months old, from seed to bloom.

Lavender is one of the most aromatic,  rewarding perennial plants to grow.  After Lavender gets established it can be a wonderful drought tolerant plant.  The foliage and flowers of a lavender plant are usually nicely fragrant.  The flowers can be purple, white, or a combination.  Foliage can be green to silver to bluish.

Lavender plants attract butterflies to the garden as well as bees and other beneficial insects.  Lavender plants like part or full sun, with six or more hours of direct sun being ideal.

For the first number of months that you grow Lavender, it is important to water regularly.  After the plant is established, a more arid dry environment is permitted due to the deep roots of the plant.  Lavender plants bloom generally in the summer.  Spacing between Lavender plants is usually best to be between 15 to 25 inches.  Lavender plants grow at a medium pace but can grow fast.  Generally Lavender will be one foot to 3 feet in height, and can be anywhere from 2 inches wide when young to many feet wide when established.  Lavender is generally not happy below 32°F.  It is best to cut back lavender flowers after flowering To promote more bloom.  It is not important to fertilize lavender, but some can be beneficial.  When planting use a porous mixture with compost, sand, and other well-drained rich nutrients. The average size of a lavender plant is about 3′ x 3′.

Many people ask me when is the best time to start planting indoors and outdoors. Although I would say anytime, now really is the perfect time. If you are in a colder climate, start planting indoors in trays. If you are in a warmer climate, plant in the ground. The banner ad below has some great web specials from Wayside Gardens.

Here are 5 watering tips to use when you water your outdoor and indoor plants.

• Do not water from above the leaves. Water at the base of the plant, just above the roots.
• Water in the morning or late afternoon so that the base of the plant can dry by evening. This timing of watering also allows the temperature not to be at peak. Watering in the morning gives the plant all day to absorb water.
• Do not water in the evening. This can prevent fungus and other diseases.
• Feel the surface of the soil as well as underneath the soil. If it looks dry from above, it may still be wet underneath.
• Plants that have been in your garden and established for more than a year will not need to watered as frequently as new plants. This is because well established plants will have stronger, more resilient root systems.

Here are some tips for bringing plants indoors for the winter from outside. First, examine the plant for insects, disease, and pests. Second, spray down the leaves of the plant with insecticidal soap. Third, isolate the plant for a couple of weeks so it doesn’t affect other plants. Fourth, after bringing the plant in with your other plants, go less on the fertilizer and watering so the plant can rest.

When it comes to fertilizing annuals and perennials in your garden, these two kinds of plants can be treated differently. First, divide your plants into groups of annuals and perennials. They can be physically divided, or divided in your mind. Annuals and perennials have different nutritional needs.

Annuals prefer a water soluble fertilizer that is high in phosphorus (the middle number) for their blooms, such as 15-30-15. This is the perfect fertilizer (click here). The water soluble fertilizer gets nutrients to them fast.

For perennials I prefer a granular fertilizer, roughly 10-10-10. This is a good long lasting fertilizer (click here). You can put the granular fertilizer around the base of the plant and it will release into the soil.

For both annuals and perennials, fertilize every 2-3 weeks during the growing season, and every month at other times of the year. This is a great fertilizer for everything (click here), including diseases. This is another good fertilizer (click here).

When working to grow vegetables in your home garden, these are five useful tips to keep in mind.

1. Vegetables generally love at least 6 hours of sun per day.
2. Vegetables like well amended, good draining soil.
3. If you can mix in compost, cow manure, and peat moss when planting, vegetables will love it.
4. When selecting vegetables for your garden at home, talk to people in your neighborhood to see what thrives. You can also ask garden experts in stores and garden centers.
5. Generally, the easiest plants to grow include beans, carrots, tomatoes, cucumbers, and squash. One good way to plant your vegetables is to plant in a number of quadrants and rotate after plants are done. You can plant root vegetables such as radishes and carrots in one quadrant, vine vegetables such as tomatoes and squash in another, and so on. By doing this, different kinds of nutrients are pulled out of the soil, and as you amend the soil you have time to replenish important nutrients.
