Winter Gardening Tips
Don @ Dolins Garden Center (801 62nd Ave N) joined us at the Historic Kenwood Neighborhood Association general meeting on 1/7/10 and brought some plants and gardening tips.
- He reminded us to try and use plants that are freeze tolerant.
- To protect palms from frost/freeze, cover palms with sheets and place a light bulb underneath at the top.
- Some good cold hardy plants - snap dragons, flowering kale, petunias. dianthus, pansies, sweet alyssum, straw flower, verbena
- Some plants that are not cold hardy in our area - geraniums, pentas, impatiens, hibiscus, cardboard palm, carissa, some ixoras & bougainvillas
- Don’t trim damaged plants yet; the damaged part will help to protect the healthy part of the plant. Wait until the end of February to trim them when we are most likely past the frost/freeze danger.
- Interesting Fact – The sun melting/burning ice off is what actually burns the leaves, not the cold. Hose off the frost in the morning to minimize this.
- Snow bush worms have come back. Spinosad will get rid of them. This is safe to use on all plants including fruits, vegetables and herbs. An added bonus, it will also kill fire ants.
- Grasshopper problem? Try Carbaryl (Sevin). Fairly safe to use, does not kill them but they go away.
- Top 10 best indoor plant air purifiers - Areca palm, ficus (long leafed), ivy, Janet Craig dracaena, peace lily, dwarf parlor palm, Rhapis/lady finger palm, Robellini palm, Boston ferns.
- New regulations will be imposed in 2011 that will prohibit fertilizing landscape plants and turf from June 1 – Sept 30. The nitrogen and phosphorus in fertilizer products are washed into the bay/gulf during our rainy season and negatively impact the quality of the water.
- Earth Boxes – These are self-watering planter boxes with everything you need. Great for growing veggies and herbs. $59.99 at Dolins.
- St Augustine grass – Uses too much water and chemicals. Should choose some other type of grass
- Poinsettias – After the holiday, keep warm and dry. Can be replanted in late March/early April. Trim in April and again in August, and keep in a dark spot in your yard away from house and street lights.
- Roses – Cut them back early Feb.
- Citrus & Palms – Fertilizer Feb, June & Oct (8-2-12 formula for palms)
- Send email to mail@Dolinsgardencenter.org to request email newsletter.
STAGHORN FERNS
The garden workshop usually has a topic or plant that is researched and discussed informally at monthly meetings. Recently, CF Hawkins, the leader of our group presented do's and don'ts and methods of mounting for Staghorn ferns.
In researching and after spending years of growing this beautiful tropical, there are two points that stand out among all the rest.
> Most people over water their Staghorn
Given that these plants originated in jungles of Africa, Madagascar and Australia, it was very unlikely that there was someone to give them a drink from the hose. Staghorns like other epiphytes get their food and water from the air and the moisture in the air. This doesn't mean that you never have to water--it just means that if the humidity is high, and we are getting some rain, watering will not be necessary. The bigger the plant the longer it takes it to dry out, so keep that in mind. Place the plant in the dappled shade of an existing tree to replicate the sunlight in its homeland jungle and it should be very happy.
> Improper Mounting can shorten the life of your plant
In their natural setting Staghorns grow vertically. That is why potting in most incidences does not work for very long. The plant will stay too moist and the fronds will not develop properly. Creativity can be key when mounting your fern as long as the vertical element comes into play. After choosing which type of base you want to use-- whether it be a board, a wire basket, or something a little more unconventional like a fish basket or a antique mailbox, just make sure it is large enough. Staghorns can get very big within just a couple of years if the conditions are ideal, which they usually are here in St. Petersburg (watch out for the occasional frost). When you mount or remount your fern the plant should look too small for the vessel you choose.
Sphagnum moss is the perfect medium to put with your fern. The moss will keep the newly "planted" fern from drying out too quickly and provide some extra nutrients (later when established a natural fertilizer like fish emulsion is the perfect balance for the established plant). Besides thinking big to ensure a long life, think heavy and strong. A mature Staghorn can weigh a lot. After a rain it can double its weight so think ahead as to how you will secure the fern as it starts to mature. Another very important factor is how you secure it to your vessel in the first place. A strong fishing line or a chicken wire base is recommended. Although not the most attractive thing when first mounted --as the plant grows you will not be able to see what has been used to secure the plant.
