Forget the gym and get to gardening?

Fun workout? We never have enough time to go to the gym or do an exercise so it's good to know that just doing something that you love can give you a workout. We all know that when we are out in the garden it gives us a bit of exercise but we do not realize how much exactly. Research says that three hours of gardening can have the same effect as an intense 1-hour gym session. The study was carried out with a group of 100 gardeners who were asked to monitor the amount of time spent doing a series of common gardening tasks over a four week period. Gardening tasks that were monitored included weeding, digging, mowing the lawn, hedge trimming, trimming shrubs and trees, raking, planting shrubs, and moving garden waste using a wheel barrow. Here are some facts and numbers:
- Just doing half an hour weeding can burn up to 150 calories and tasks that handle heavy electrical equipment such as hedge trimming will give you a good workout burning 400 calories per hour.
- Spending a day or five hours each week in the garden will burn up to around 700 calories
- Over a gardening season that works out at 20,000 calories per year, equivalent to running seven marathons
- The gardening hobby could help burn a million calories over a lifetime.

Calories burned with only 1 hour of:
340 cal - Chopping wood, splitting logs, gardening with heavy power tools, tilling a garden, chain saw. Mowing lawn, walk, hand mower. Shoveling by hand.
272 cal - Carrying, loading or stacking wood, loading/unloading or carrying lumber, digging, spading, filling garden, composting, laying crushed rock or sod. Clearing land, hauling branches, wheelbarrow chores.
238 cal - Operating blower, walking. Planting seedlings, shrubs, trees, trimming shrubs or trees, manual cutter. Weeding, cultivating garden.
224 cal - Raking lawn, sacking grass and leaves
136 cal - Picking fruit off trees, picking up yard, picking flowers or vegetables. Walking, gathering gardening tools.
102 cal - Walking, applying fertilizer or seeding a lawn
34 cal - Watering lawn or garden, standing or walking

Cold protection - winter action for your plant collection

A note from our customer: Last winter was very cold here in Arizona, lower 30's. I used white synthetic sheets (called frost cloth, it is very light and yet effective) to cover my fruit trees, and kept simple light garlands on for the whole night. Sending you couple photos so you can share with others. It worked pretty well for my plants and no cold damage!

With winter approaching, it is time to take some actions to protect your rare plants from cold stress and damage.
If you live in a mild climate, you still need to get ready for the cold nights. When expecting a cold night, individual plants and trees can be wrapped with sheets, or blankets, to protect them from the wind chill. Christmas lights is a good idea for an additional warm up.

For large collections of tropical plants, temporary winter greenhouse doesn't have to be expensive. An easy-assembly mobile carport from a hardware store covered with a plastic or fabric will cost you $100-200. It can fit a hundred plants or more!

If you live in area with a hard freeze, Southern exposure windowsill will work for most of the compact tropicals providing proper care. Larger collections may also move into your garage for a few cold nights, or for longer periods if the garage has a bright light source.

Factors affecting tropical plant winter survival:

1. Duration of cold period. Tropical plants can't stand long periods of cold. A few days of even upper 30's may kill a tropical plant. A few hours of frost may cause leaf drop but the plant will recover.
2. Minimum temperature - of course, the warmer the better. But see 1) - if cold is not for too long, it may be OK.
3. Wind-chill can be more dangerous than low temperatures.
4. Exposure. Southern slopes get warm during daytime and stay warm longer.
5. Protection with a house, fence, larger trees - where a "pocket" of warm air forms and stays - is beneficial.
6. Humidity. A lake or a river nearby (especially ocean) will mild the micro-climate.
7. Individual species hardiness. Don't try to grow Orchid Tree outdoors in New York.
8. Plant maturity and health. A well-established plant with developed root system has more chances to survive cold. If a plant had a good change to develop during warm season (bright light, enough water, fertilizer), it will be more cold hardy. Healthy plant can withstand lower temperature, so proper nutrition is important, including micro-element applications. Large specimens, even ultra-tropical, may survive cooler winter than they normally do in their natural habitat. The Nature provided plants with better hardiness level than it is normally used. To boost plant immune system and improve cold tolerance even more, use SUNSHINE plant boosters. SUNSHINE-T - thermo-protection booster, is specially formulated for winter protection of tropical plants. To improve cold hardiness, spray 1-2 days prior to cold with 5 ml/1 gal solution and continue applications with 2.5 ml/1 gal solution every 10-15 days throughout winter period.
9. Gradual temperature decrease is less dangerous than a sudden drop since it gives a plant a chance to adjust. One sudden freeze in December with prior warm fall may create more damage than a gradual temperature adjustment. If it starts to get cold early in the Fall, plants slow down their metabolism, and the new tender growth won't get hurt later in winter, since the plants are "expecting" the cold.
10. Do not fertilize plants during cool months. Not only because they don't need much food beyond growing season, but also because fertilizer (especially Nitrogen) encourages rapid tender growth that will be damaged by cold and this will stress the whole plant.

Stay warm!

Hardy avocados

Q: I intend to gift three avocados, at least one type A and one type B, to a friend who lives in an area where the temperature never goes below 25F. The idea is to give them a ripening season as long as possible. Which combinations do you suggest, and which are the A and B?

A: When talking about "A" type and "B" type in Avocados, it is referring to the flowers. An avocado will produce both male and female flowers on the same plant. "A" type means that the flowers are female in the morning and male at afternoon. "B" type means that the flowers are male in the morning and female in the afternoon. If you plant to start a commercial growth, then it's important to create a proper mix of both types. However, in hot and humid climate a single tree produces flowers of both types, so it is not necessary to have both A- and B- types planted together in backyard. Even a single tree produces enough fruits for home gardener.

It is also important to know that while there are more cold hardy avocados, it refers to a full grown established tree. They will still need protection from the cold until they are bigger and more established. One can not expect a small tree, which was planted in June, to survive the first winter. It'll take few years until the tree is "harden" enough.

Wurtz Avocado: Fruits from May to Sept. Dwarf hybrid. It is very compact and slow growing, reaching only about 8-12 feet at maturity. Distinctive weeping growth habit. Suited for planters, containers, patios, greenhouse use. Great for dooryard or container growing. The tree can handle temperatures to 25(F) degrees. Production is good and it is a consistent bearer.

Day Avocado: Fruits July to Sept. Day avocado is green, smooth skin and is shaped like a club. The fruit is of very good quality and has a nice buttery consistency. The slender tree is relatively cold tolerant and produces July through September.

Fuerte Avocado: Fruits Nov to June. Relatively cold hardy variety. Green fruit, elongated,flavor excellent, buttery. Vigorous compact tree with decidedly alternate year bearing habit. Ripens November to June.

These three will provide you with fruit ripening during the whole warm season. For the most cold hardy avocado varieties, see this info sheet.
