Rabbit Foot Fern

 

Rabbit foot fern has lacy leaves.

Rabbit foot fern, Davallia fejeensis, is one of those few plants that actually seems to be happier in pots, particularly unglazed terracotta pots that stay damp where its oddly fuzzy rhizomes creep over the edges. Besides, pots have the advantage of portability, so that appealing plants can be brought into the home as houseplants, even if only for a few months at a time. Rabbit foot ferns that lose leaves because the air in the home is too dry should recover if moved to a shady and humid spot out in the garden for a while.

The fuzzy rhizomes are as appealing as the foliage, and can creep a foot or even more if they wrap around a pot. They rot if buried, so should be spread out over the surface of the potting soil when small plants get put into larger pots. The very lacy foliage can get a foot deep in damp and partly shady spots. Foliage is shorter and more dense with more sunlight.

Late Night Terror For Foliage

Snails and slugs really crave hostas.

Snails and slugs really enjoy all the new seedlings and fresh foliage that is growing in the garden while the soil is still damp from earlier rain, and the weather is getting warmer. They are neither too smart nor too fast, but they are very hungry, and do their damage at night when no one is watching. They hide before the sun comes up.

The same lush foliage that they eat is also where they often live. However, they also live among lily-of-the-Nile and some ferns that they do not damage very much, as if they think that no one will look for them there. They also hide under any sort of debris and in valve boxes. Removing such debris and unwanted weed foliage diminishes their habitat.

Pieces of damp cardboard intentionally left out in cool and damp spots in the garden overnight can attract snails and slugs as they seek shelter in the morning, and then be flipped over during the day to collect and dispose of the surprised snails beneath. It is sneaky, but effective. People who happen to be up late can hunt for snails while they are out and about. Otherwise, hunting for hiding snails and slugs by daylight takes a bit more diligence.

Saucers or plastic lids containing puddles of beer is supposed to keep snails and slugs out drinking until they get roasted when the sun comes up. The problem is that the beer gets washed away whenever the garden gets watered. Besides, it does not really kill very many victims. Salt around the most susceptible plants likewise gets washed away, and can be toxic to the plants that it is supposed to protect. Keeping water in drainage saucers below potted plants is a problem for drainage, and allows mosquitoes to proliferate.

Copper tape that can be purchased from nurseries or hardware stores is an effective barrier for snails and slugs, but only if the susceptible plants are completely surrounded, and only if leaves or stems that extend over the copper do not touch anything outside. Copper tape can be self adhesive or stapled to wooden planters. Bare copper wire is just as effective. If wrapped around tree trunks, copper tape or wire should have some slack to allow for growth. An extra bit of self adhesive copper tape pressed against itself to form a tab that it can be pulled apart as needed should work well. Copper wire only needs a small loop of extra wire.

Squirrel!

Technically, this old article does not conform to the ‘horridculture’ meme for Wednesday. I just dislike squirrels.

P80408Wildlife and domestic animals seem to follow me everywhere I go. When Brent and I lived in the dorms at Cal Poly, our room was known as the Jungle Room, not only because of all the greenery, but also because every little bird that got knocked out while trying to fly through the big windows at the dining room was brought to our room to recuperate. A baby squirrel that weaseled into my jacket while I was out collecting insects for an entomology class lived with us for a while. There were two baby ducks that need a bit more explaining.

When I moved south of town, where my roommates boarded horses, the horses worked diligently to open their gate to come to the house to eat my rare plants. The neighbor’s cattle sometimes did the same! When it rained, creepy crawdads came out of the ditch at the railroad…

Grape Hyacinth

Grape hyacinth is very reliably perennial.

Are they reliably perennial or invasive? In ideal situations, old fashioned grape hyacinth, Muscari armeniacum, can get a bit too eager to proliferate and migrate. Not only do their bulbs divide efficiently, but their seed disperse beyond bulb colonies. However, bulbs do not migrate too rapidly for containment. Thorough deadheading inhibits seed dispersion.

Grape hyacinth provides some of the earliest spring bloom. Floral spikes of tiny rounded flowers do not get much more than six inches tall, but are delightfully abundant. The rich blue color is exquisite. Hybrids and other species can bloom with pale pink, pale purple, white, yellow, or various shades or tints of blue. The grassy foliage is somewhat rubbery.

If they do not migrate efficiently enough, established colonies of grape hyacinth are easy to divide in autumn. Of course, it will be necessary to mark their locations as their foliage dies back at the end of spring. Division is easier and faster than growing new plants from seed. If hybrids produce seed at all, it may not be viable. If it is, it may not be true to type.

Deadheading Spring Bulbs Conserves Resources

What happens when daffodils finish blooming?

Now that the various spring bulbs have finished blooming, or will soon, many will benefit from deadheading. The techniques are simple, and actually benefit many plants besides spring bulbs. In the most basic terms, deadheading is merely the removal of deteriorating flowers after bloom. Ideally, it should happen prior to the development of seed structures.

A most obvious advantage of deadheading is that it eliminates unappealing carcasses of finished flowers. This neatens the appearance of remaining foliage. The foliage of some spring bulbs shrivels soon after bloom, but remains intact through the process, to sustain development of new bulbs. It is easier to ignore without prominently shabby floral stalks.

Deadheading also conserves and redirects resources that would otherwise sustain seed production. Such resources can instead promote vegetative growth, including production of new bulbs to replace the old. Furthermore, depriving bulbs of seed provides an added incentive for vegetative regeneration. If unable to survive by one means, they try another.

Some bulbs are more reliant on deadheading than others. Grape hyacinth and snowdrop are too profuse with bloom for minor seed production to inhibit their performance. In fact, they produce viable and genetically stable seed, which could be an advantage if more of the same are desirable. Although seed production is limited, seed disperses extensively.

Dutch crocus are an example of sterile hybrids that are unable to produce viable seed, or waste associated resources on such efforts. Other extensively bred bulbs that are not so sterile may not be true to type. Consequently, their progeny are likely to be very different. Freesia do not require deadheading, but can produce feral seedlings with insipid bloom.

Lily, narcissus, daffodil, tulip and hyacinth are some of the popular spring bulbs that now are ready for deadheading. Summer bulbs and perennials will get their turn later. Canna, dahlia and perennials that continue to bloom through summer will be tidier, and perhaps bloom more abundantly with efficient deadheading. They need not wait until next year to express their gratitude.

Happy Easter!

No one should be blogging today. I wrote this three years ago, and not on Easter.

P80401Happy Easter!

This is one of those holidays when no one should work, which is why I wrote this a few days ago, and scheduled it to post today. I hope you are not reading this today. You have more important things to do. Lent and the forty days of fasting that goes with it are over, so you can eat all the Easter eggs and anything else you want.

The only work that should be done today are chores that can not be delayed until tomorrow. With the weather warming (at least in our region), watering might be one of those chores. For most parts of the garden, this might be the first watering since autumn. Although the rain has been meager, cool weather had kept things damp until now. Resuming watering is typically an easy task. It sounds simple enough. Water is water – right?

I get all…

Cherry Blossom Festival

My Six on Saturday post this morning linked to this three year old article, which describes how the historic flowering cherry trees have been deteriorating for quite a while.

tonytomeo's avatarTony Tomeo

P80324KI would say that this is our own private Cherry Blossom Festival, but it really gets a crowd. These two old trees are at the edge of the main roadway through town, so several people driving by stop to take pictures. They may not seem to be very impressive compared to healthier flowering cherry trees, but they are what we have, and we are happy to get the bloom.

Decades ago, fruiting cherries were some of the more common orchard trees in the Santa Clara Valley. Flowering cherries were only somewhat popular in home gardens, and might have been less popular without the Japanese influence. They are more popular in cooler climates, not only because they are happier in cooler climates, but also because those who live where winters are harsh have a better appreciation for bloom that so happily celebrates the end of winter.

These particular trees are unfortunately…

Six on Saturday: Festival des Fleurs de Cerise

Beau prefers French. I do not know why. He was born in Missouri. His name is derived from ‘Hobo’ (‘HoBeau’). Since vehicles here are traditionally named after places, he may believe that his name was derived from ‘Boulder Creek’ (‘Beaulder Creek’) or Bonny Doon (‘Beaunny Doon’). Nonetheless, there is nothing French about Beau. I do not argue. Nor do I argue with Rhody if he insists that Beau is a Pontiac rather than a Chevrolet. If he believes that we ride in that kind of style, it is just fine with me. Anyway, after last Saturday, some wanted to see Beau.

1. Two years after we intended to remove this pair of historic flowering cherry tree, they get to bloom one last time. Sadly, their demise can be delayed no longer. Their trunks are too rotten.

2. Three similar flowering cherry trees down the road have been recovering from foliar disease during the same two years. They are neither as pretty nor as distinguished, but have potential.

3. Adjacent to #2, this most garish flowering cherry tree is the most prominent. Unfortunately, like #1, it is deteriorating, so will also be removed after bloom. Half of the canopy is necrotic.

4. This one should succumb instead. To me, weeping flowering cherries look weird. This one was in bad condition when I met it. Unfortunately, my efforts to renovate it have been effective.

5. Oh, my favorite. The flowers are double, but not as fluffy as those of #3. It really is as white as it looks, without any blush. The tree is disfigured and shaded by redwoods, but blooms well.

6. Beau was the unseen star of my previous Six on Saturday. He is neither French nor related to ‘the’ Beau of the Frustrated Gardener, but is pretty cool anyway, and drives on the right side.

This is the link for Six on Saturday, for anyone else who would like to participate:

California Poppy

Wild California poppies are bright orange.

Even after so many pretty shades of yellow, red, pink and and white have been been developed, the natural orange of the native California poppy, Eschscholzia californica, is still the best. That is probably why they all eventually revert to orange after reseeding. Although native, they do not reseed everywhere, and actually seem to be more reliable in unrefined and unamended areas of the garden than in rich soil with generous irrigation. However, a bit of watering can prolong sporadic bloom until autumn. Bloom otherwise ends before warm summer weather.

California poppy is grown as an annual because the perennial plants get tired rather quickly. They fortunately self sow prolifically. Flowers are typically about two inches wide, with four petals. The intricately lobed leaves are slightly bluish. Foliage is not much more than half a foot deep.

Weeds Are Full Of Surprises

Pokeweed is rapidly becoming more common.

While it was busy naturalizing in Australia, South Africa and southern South America, the California poppy was getting forced out of parts of its own native range by more aggressive exotic plants that were also busy getting naturalized. Technically, any plant that is not native is exotic. Any exotic plant that becomes naturalized in a foreign environment is able to proliferate without any help, as if it were native. Naturalized exotic plants that get too aggressive become invasive weeds.

Weeds are plants where they are not wanted. This is a very broad definition that includes plants ranging from simple little dandelions in urban lawns to humongous bluegum eucalyptus in forests. Naturalized exotic weeds can be much more problematic than weeds that can only proliferate where they get watered in gardens and landscapes, because they can get established where they are not expected.

Water hyacinth that clogs the Sacramento and San Joaquin River Delta is not often a problem in terrestrial landscapes. However, giant reed, pampas grass, Acacia dealbata and blackberry brambles can infest home gardens just as easily as they infest wild lands. Because they do not need to be watered, they can get established and grow quite large in unused parts of the garden before anyone notices.

Many naturalized weeds somehow seem to much more aggressive and problematic than even the most prolific of native plants. Even the common native lupines are relatively docile compared to annual oat grass. Native blackberry may seem impossible to eradicate, but is actually neither as persistent nor as unpleasant to handle as the exotic Siberian blackberry!

Young weeds are easiest to pull now while the soil is still evenly damp, and young roots are only beginning to disperse. They will be more difficult to pull after roots are dispersed and soil hardens. Tree weeds and large perennial weeds that were cut down last year instead of pulled will likely need to be dug. Bermuda grass is a relatively low perennial grass that always seems to be difficult to dig. Mowing or cutting down annual grass weeds with a weed whacker will not eliminate them, but limits the development and dispersion of seed for the next generation. Burclover, sowthistle, bindweed, purslane, spurge and the various oxalis are some of the other common weeds that really get going this time of year.
